A second sealed and peel-away cavity includes a catheter advancement mechanism which provides for lubricated catheter advancement without actual contact of the catheter by the human hand. An absorption member is provided to semi-solidify urine stored in the urine storage reservoir.

Abstract: A penile catheter system for urine collection or catheterization where an external catheter secures over the penis and connects to a collection bag through a two-way urine valve, whereby urine can be passed to the collection bag through the two-way urine valve, or whereby catheterization can be accomplished through the two-way urine valve by a catheter with a unique shield that protects the catheter from bacteria laden interior walls of an external catheter. A two-way urine valve can be positioned for urine collection or catheterization as desired.

Abstract: A stent for assistance in draining urine from the kidney into the bladder through the ureter which may be partially or totally occluded. The stent has the capability to selectively inject a liquid, such as a dye, into the renal system. The stent is fabricated from a biocompatible tube, preferably of silicone rubber. The proximal and distal ends of the tube are preformed into a pigtail or other shape to secure in the renal and bladder cavities, respectively. The proximal and distal ends of the tube are perforated to provide for ingress and egress of the urine. During the implantation procedure, a guide wire is first advanced to provide a path for positioning the stent. The stent is advanced over the guide wire by pushing with a multiple diameter injection catheter. The smaller diameter proximal end of the injection catheter is positioned within the distal end of the stent at a predetermined fixed distance which occludes the distal perforations.

Abstract: An applicator for an external male urinary catheter is described for applying and securing a catheter to a user. The applicator has a solid cylinder preferably with slits surrounded by a flexible skirt on which the catheter is installed, and the cylinder causes the skirt to invert to apply the catheter to the user.

Abstract: A factory preassembled, preferably partially prefilled three piece penile prosthesis that can be implanted in a patient as one pre-assembled unit and filled without any required further connection or purging of air. The prosthesis has a pair of inflatable cylinders that can be implanted into the corpora cavernosa regions of the penis, the inflatable cylinders preferably being attached to a solid rear portion to which the various tubing is connected. The prosthesis also has a reservoir for implantation into the abdomen, a pump for implantation into the scrotum for transferring fluid from the reservoir into the cylinders, and a controllable valve associated with the pump for retaining the fluid within the cylinders and for controllably allowing it to escape from the cylinders back into the reservoir when desired. When fluid is pumped into the cylinders, the cylinders are inflated to to encourage the penis to an erect position.

Abstract: The present invention comprises a prostate dilation balloon disposed on a urethral catheter, a fixation balloon also disposed on said catheter, wherein said catheter is partially or completely transparent, and a fiber optic endoscope disposed within said catheter. The scope is arranged so that it can visualize the area outside the catheter in order to determine whether the dilation balloon and fixation balloon are properly located within their respective targets within the urethra and/or bladder. The scope is also capable of focusing on objects which may be present in and along the urethra.

Abstract: A penile prosthesis with a two piece inflatable cylinder that provides significant lengthwise expansion of a male penis. The cylinder has an inflatable bellows attached to an inflatable member and a sheath that extends from a base member. The bellows is attached to the base member and the sheath is connected to the inflatable member, such that the sheath will stretch when the bellows is inflated. The sheath surrounds the bellows. The sheath is constructed from an elastic material that can expand up to 100% of its original length. The inflatable member and bellows are connected to a pump which transfers fluid between a reservoir and the cylinder. When fluid is pumped into the cylinder, the bellows and inflatable member are inflated and the sheath is expanded, allowing the inflatable member to move into an elongated position. When the cylinder is inflated the sheath is in tension, wherein the sheath will pull the inflatable member back into a compact position when the bellows is deflated.

Abstract: A scope and stent system, the scope providing visibility not only through the urethra but also through the ureter during the insertion and placement of a ureteral stent. The scope is in the form of a fiber optic bundle having an appropriate provision for lighting and lensing thereof, and preferably having a video camera and monitor responsive to the image formed at the opposite end of the scope for viewing during the scope insertion process. The fiber optic bundle itself is made sufficiently small so that the entire scope may be fabricated with the appropriate dimensions of a typical stent guide wire and made sufficiently flexible for negotiating a tortuous path as required.

Abstract: A technique for the treatment of male impotence. The apparatus to be implanted in the corpus cavernosum of the penis is a cylinder of an implantable polymer. The cylinder is generally flexible and has a plurality of transitions from a lesser diameter to a greater diameter. As the cylinder is filled with fluid under pressure, the areas of lesser diameter tend to expand, thereby effectively lengthening the cylinder without an unacceptable increase in girth. Optional rings may be positioned over the areas of lesser diameter to prevent collapse. An optional outer sheath also improves longitudinal stability.

Abstract: An apparatus for the treatment of male impotence. The apparatus has a cylinder of a biocompatible polymer which is implanted in the corpus cavernosum of the penis. The cylinder is attached at its proximal end to a base mount which is implanted in the pelvic area. In the flaccid state, the cylinder is empty and limp, and a spring within the cylinder folds the cylinder wall in upon itself to decrease its effective length. Fluid is pumped into the cylinder causing it to stiffen in the erect state. The effective length of the cylinder is increased by the addition of the fluid which compresses the internal spring and unfolds the cylinder. In this manner, the length of the penis is increased from the flaccid to the erect state.

Abstract: A penile prosthesis employing an improved pump and valve system. The main body of the prosthesis has at least one inflatable polymer cylinder suitable for implantation within the corpus cavernosum of the male patient. The penis of the patient is rendered erect by pumping a sterile fluid into the inflatable polymer cylinder(s) under adequate pressure.The sterile fluid is supplied from a reservoir and pump implanted within the scrotum of the patient which are linked to the inflatable polymer cylinder(s) by flexible tubing. The reservoir is a relatively low pressure flexible polymer bag of relatively large volume. Coupled to the reservoir by a valved diaphragm is a pump having only much less flexible walls and a relatively small volume.Manual squeezing of the reservoir forces sterile fluid through the valved diaphragm into the pump chamber.

Abstract: There is disclosed a connector for attachment of flexible plastic tubing which is most compatible with filament reinforced tubing which resists elastic expansion. The connector has a central radial flange with opposite cylindrical ends which provide mandrels to receive adjacent ends of tubing. A cylindrical cage surrounds the cylindrical ends and supports chuck members. A pair of collet members are provided which slide over the tubing and the chuck members, compressing the chuck members radially inwardly without axial movement of the chuck members relative to the tubing. This deflects the chuck members into the wall of the tubing, thereby locking the tubing securely onto the mandrel. The collet member has an internal annular groove on its inside wall which receives an outer edge of the chuck members, thereby serving as a detent or interlock to resist the retraction of the collet member once it is moved into final position.

Abstract: A tissue expanding device includes a substantially non-extensible base and a top layer joined to the periphery of the base such that the base and the expansion layer are in contact with each other when the device is in a non-expanded state. In the non-expanded state, the device has a thickness substantially equal to the thickness of the combined thickness of the base and expansion layer.

Abstract: A penile implant includes an elongated member for implantation in the penis that is in fluid communication with a reservoir. The member includes an enclosure having a pressurizable chamber section such that the member is transformable between a flaccid and an erect state and a pump for transferring fluid from the reservoir to the pressurizable chamber. The pump has a valve portion made of a deformable material such that when the valve portion is deformed, fluid flows from the pressurizable chamber to the reservoir making the member flaccid. The valve portion is surrounded by a cushioning material to protect the valve portion from being accidentally deformed, permitting fluid to flow from the pressurizable chamber back to the reservoir.

Abstract: A valve for use in a fluid fillable device includes a main body portion movable from a fluid position to a curled fluid sealing position. The main body portion includes a sealing section made of an elastomeric material and having a passage portion defining a passage for receiving a fill tube. The passage portion is flanked on opposing sides by first and second portions of elastomeric material. The passage portion is in a stretched state relative to the first and second portions, such that the passage portion curls along the passage when the fill tube is removed.

Abstract: A surgically implantable prosthesis, such as a mammary implant, that is rendered rupture-resistant by injecting a liquid with uniformly dispersed lubricating material into a flexible creasable shell during manufacture or surgical implantation. The lubricating material, such as polyvinylpyrrolidone, polyvinyl alcohol, hydroxyethyl starch, or lecithin is uniformly dispersed in a carrier inflating liquid such as normal saline. The lubricating material reduces frictional wear along opposed inner surfaces during sliding contact in a creased area in the shell wall after surgical implantation.

Abstract: An implantable, positionable penile prosthesis which comprises an elastomeric rod and a metal wire coil coaxially imbedded within at least a portion of the rod. The coil has a radius, number of turns per unit length, and wire diameter which combines with the elastomeric rod for substantially retaining the position into which the prosthesis is bent and for inhibiting fatigue of the metal wire coil when the prosthesis is repeatedly bent for positioning.
