Abstract: A lid for a medical implant has a first part, a second part and engaging means. The second part is rotatable relative to the first part such that, in use, rotation of the second part relative to the first part causes the engaging means to engage with and attach the lid to the implant.

Abstract: The presently described catheter is an improved multi-function hypospadias catheter adapted to be urethrally inserted and secured within a patient's bladder using an attached internal crescent shaped retention balloon. The inverted crescent configuration of the balloon reduces the contact surface area between the balloon and a patient's bladder wall to reduce bladder spasms. The catheter is removed from the patient (when needed) via deflation of the crescent shaped balloon, which deflates completely so as to not contact a patient's urethra during insertion and removal of the catheter. The catheter includes a double lumen with a one-way flow valve. One lumen provides a passageway to drain urine from a patient's bladder. The second lumen provides a passageway to inflate and deflate the crescent shaped retention balloon.

Abstract: In some embodiments, an external bladder management system that is configured to reside within a urine collection receptacle (e.g., a toilet) includes a body that houses a fluid testing chamber. The fluid testing chamber is fluidically coupled to a fluid inlet and a fluid outlet. The system further includes a fluid capturing funnel fluidically coupled to and extending from the body and configured to couple the body to the urine collection receptacle. The system further includes an optical sensor disposed within the body and including (1) an emitter configured to convey light across the fluid testing chamber, and (2) an optical detector capable of measuring an intensity of the light as the light exits the fluid testing chamber. The fluid inlet, fluid testing chamber, and fluid outlet are collectively configured to encourage a laminar flow profile of the fluid as it flows through the fluid testing chamber.

Abstract: In general, the present invention is directed to systems and methods for providing ostomy faceplates in proximity to negative pressure wound devices. This may be achieved, for example through the use of an ostomy appliance or faceplate with a non-circular flange for attachment of a bag or pouch. In accordance with some embodiments, this non-circular flange may be substantially “D”-shaped, and/or have at least one substantially straight edge. In some embodiments, the ostomy faceplate may itself be noncircular and/or “D”-shaped; may include a cutting guide for cutting materials used with an NPWD; may contain an asymmetrically located aperture; and/or may comprise one or more tapered edges.

Abstract: A urinary catheter and container are described. The urinary catheter may have a catheter shaft attached to a handle, and a coating disposed on an outer surface of the catheter shaft. The coating may include a hydrogel, water and/or glycerin, and a polyethylene gylcol (PEG). The PEG may have a molecular weight equal to or less than 600, for example one or more of polyethylene glycol (PEG) 300 and PEG 400. The coating may be applied in a wet state and remain wet for an extended period of time in the container, thereby obviating the need for a lubricant, such as a water sachet or gel package, to accompany the catheter in the container. The container may include a gas impermeable foil material. The container may include an adhesive tab covering a perforated section, the adhesive tab including a pull loop.

Abstract: A medical device wherein the device has an outer surface coated with an oleophilic lubricous coating or the device is formed from a mixture including a polymer and an oleophilic compound.

Abstract: Ureteral bypass devices and procedures for performing internalized urinary diversions within patients. Such a procedure includes implanting a first catheter and securing a distal end of the first catheter within the renal pelvis or ureter of a patient, implanting a cystostomy catheter through and securing a distal end of the cystostomy catheter within the urinary bladder of the patient, fluidically connecting proximal ends of the first and cystostomy catheters to an adapter, and then subcutaneously implanting a sampling/flushing port and fluidically connecting a proximal end of the sampling/flushing port to the adapter via a third catheter to yield an artificial ureteral bypass device, in which the first and cystostomy catheters are fluidically connected together and fluidically connected to the subcutaneously-placed sampling/flushing port.

Abstract: Provided is a medical device with portions configured for fitting and being retained simultaneously into two cavities on opposite sides of the body of a subject, for example the eustachian tubes or the fallopian tubes. The device may include an elongated member with a central segment and first and second peripheral segments extending therefrom. These segments differ in their intended function and eventual in situ positioning: the two peripheral segments intended for insertion and positioning within the two cavities and exerting their function within the cavities. The central segment serves as a link between two peripheral segments and may also be used for some other functions by its position. The elongated member may have elastic properties.

Abstract: A catheter assembly includes a catheter at least partially positioned within a sleeve. The catheter has a coating, which produces a low-friction surface on the catheter when treated with an activating fluid. A protective tip is connected to the sleeve and has proximal and distal internal seals, with the proximal seal at the proximal end of the tip or between proximal and distal ends of the protective tip. A cap of the assembly has a projection, which is removably received within the protective tip for sealing engagement with the proximal and distal seals to define a fluid reservoir within the protective tip. An activating fluid is contained within the fluid reservoir. The projection may be partially hollow to receive a portion of the catheter. The sleeve may be relatively narrow or at least have a narrowed portion for better distribution of activating fluid to the surface of the catheter.
