Abstract: An external bolster for a medical catheter, the external bolster comprising an integral strain relief member for diminishing the effect of an externally-directed force applied to the medical catheter. In a preferred embodiment, the external bolster is a flexible, unitary member comprising a lower portion and an upper portion. The lower portion comprises an annular base, the base having a top surface, a bottom surface and a central opening. A plurality of spaced apart feet extend downwardly from the bottom surface of the base. A sleeve extends upwardly from the top surface of the base in alignment with the central opening, the sleeve and the central opening jointly defining a bore of uniform cross-section. The upper portion comprises an elbow-shaped tubular member having a vertical portion, a horizontal portion and a longitudinal lumen. The vertical portion of the tubular member is disposed on top of the sleeve, with its lumen aligned with the bore.
Abstract: An endoprosthesis includes a plurality of struts defining a flow passage. At least one strut includes (a) a body comprising a bioerodible material and having a thickness and (b) a coating overlying the body. The coating includes a plurality of regions that allow physiological fluids to contact a plurality of corresponding areas of the underlying body when the endoprosthesis is implanted in a physiological environment. The plurality of regions are sized and arranged so that the contacted areas of the body erode substantially through the body in the thickness direction while the coating remains on the body when the endoprosthesis is implanted in the physiological environment.

Abstract: An intravascular catheter that exhibits the combined features of superior flexibility, softness, radiopacity and oval/kink resistance. The catheter includes an elongate shaft having a proximal region, a distal region and a lumen extending therethrough. The proximal region of the shaft includes an inner lubricious polymer layer, a reinforcement layer and an outer layer. The reinforcement layer comprises a braid having one or more metallic members and a plurality of polymer members wherein each polymer member comprises a plurality of monofilaments, preferably formed of LCP. The polymer members of the braid provide improved flexibility and softness in addition to high burst pressure. The metallic member(s) of the braid provide improved radiopacity and oval/kink resistance. The catheter may also include a longitudinal member extending along the reinforcement layer.

Abstract: The invention generally relates to surgically implantable supportive slings. More specifically, in various embodiments, the invention is directed to sling assemblies for pelvic floor repair that utilize one or more materials, attached without a mechanical fixation device, and related methods of use and fabrication.
Abstract: Stent delivery catheters comprising a hypotube, which may be a micromachined member, disposed on an outer portion of an inner member that may be an extruded multi-lumen member. The hypotube may be secured to the inner member. The devices may be adapted for delivering a self expanding stent by providing a restraining structure or device over the stent during delivery. One or more actuating members are provided through a lumen in the inner member to actuate the restraining structure and release the stent. Methods of use of such catheters are also described.
Abstract: An embodiment of the invention includes a device for collecting body tissue. The device may include an inner member comprising a hollow portion to collect body tissue and a distal end configured to both penetrate body tissue and define an opening of the hollow portion. The device may further include an outer member, co-axially and slidably disposed around the exterior of the inner member, comprising a distal end portion. The distal end portion of the outer member may be configured to penetrate body tissue, prevent body tissue from exiting the hollow portion of the inner member, and allow the distal end of the inner member to extend beyond the distal end of outer member. The opening of the hollow portion of the inner member may be disposed in a plane that is not perpendicular to the longitudinal axis of the inner member.

Abstract: The invention provides, in various embodiments, systems, devices and methods relating to adjustable length implantable sling assemblies for providing support to anatomical locations. In certain embodiments, the sling includes at least one elastic member to aid in the placement and tensioning of the sling.
Abstract: According to an aspect of the invention, urological medical devices are provided, which comprise a prostatically beneficial agent selected from alpha-adrenergic blockers, antispasmodic agents, anticholinergic/antimuscarinic agents, calcium channel blockers, anti-inflammatory agents, hormone affecting agents, anti-cancer agents, and combinations thereof, among others. The urological medical devices are adapted for implantation or insertion into a subject's urinary tract, whereupon at least a portion of the prostatically beneficial agent is released into the subject's prostatic urethra. The release profile of the prostatically beneficial agent is effective to treat a prostatic disorder, for example, benign prostate hypertrophy, prostate cancer or prostatitis, among others. Other aspects of the invention are directed to treating prostatic disorders.
Abstract: A catheter system is provided that permits easy cannulation and radiological examination of the biliary and pancreatic ducts during an Endoscopic Retrograde Cholangiopancreatograhy (ERCP) procedure. The system of biliary catheters provides for a method of gaining access to the biliary tree, particularly when the contralateral wall or septum of the biliary tree interferes with access to the biliary tree. This anatomical interference is remedied using a pulling biliary catheter that withdraws the papilla of Vater away from the contralateral wall or septum by pulling proximally upon a chute expanded within the papilla of Vater. The enlarged opening then permits additional medical devices to be advanced through the pulling biliary catheter into the desired duct requiring the ERCP procedure.
Abstract: A method of preparing a cutting balloon comprises the steps of providing a balloon body having an exterior surface, an unexpanded state and an expanded state; and engaging at least one blade to the exterior surface when the balloon body is in the unexpanded state.
Abstract: Probes that are sensitive to electrode/tissue contact and that are configured to connect an electrode to a power supply and/or provide an indication when the desired level of electrode/tissue contact has been achieved.
