Disclosed herein are devices for treating symptoms of a urinary tract dysfunction having an expanded volume within the range of from about 1 cc to about 400 cc. In one embodiment, the device comprises a valve having a first membrane and a second membrane with a flow passage therebetween for filling the attenuation device. In another embodiment, the device comprises a valve for permitting the filling of the attenuation device through a filling device.

Disclosed herein is an attenuation device, comprising a flexible housing and a high vapor pressure media having a vapor pressure approximately equal to the intravesical pressure of the bladder and a permeability of less than 1 ml / day at body temperature through the outer wall of the flexible housing. In one embodiment, the high vapor pressure media comprises perfluorooctylbromide. In another embodiment, the high vapor pressure media comprises perfluorohexane. In yet another embodiment, the high vapor pressure media comprises perfluorodecalin. Also disclosed herein is a method of treating a patient, comprising providing a compressible attenuation device and introducing within the attenuation device at least one high vapor pressure media.

The present invention relates to the regeneration, reconstruction, repair, augmentation or replacement of organs or tissue structures using scaffolds and autologous cells that are not derived from such organs or tissues.

A ureteral stent for assisting movement of urine along a patient's ureter and into the patient's bladder. The stent includes an elongated tubular segment extending toward the bladder from a kidney end region for placement in the renal cavity to a bladder end region. A central lumen connects at least one opening at the first end region to at least one opening in the bladder end region. Thin flexible tail(s) are attached to the bladder end region of the tubular segment at a point outside the bladder so as to receive urine from the opening in the bladder end region and to transport urine from there across the ureter / bladder junction and into the bladder. The tails include an elongated external urine-transport surface configured to transport urine. The transporting surface(s) are configured to extend along at least part of the ureter, across the ureter / bladder junction, and into the bladder.

A catheter assembly including an elongate member having a proximal end and a distal end. The distal end has at least one drainage opening. A hydrophilic coating is provided on at least a portion of the elongate end of the catheter. A fluid containing member is provided and is either arranged on the elongate member or within a separate area of the container. The fluid containing member contains sufficient hydrating fluid to hydrate the coating of the catheter. A container contains the elongate member and the fluid containing member and incorporates at least one foil layer to prevent evaporation of the hydrating fluid. A method of using the catheter includes inserting a catheter into a user's body and draining fluid from the user's body.

The current invention provides this advance in infection control via its unique application of active sterilization to a catheter or implant. While most catheters, and many implants, are passive devices, the current invention will provide an active component as a integral part of the implanted catheter or device to continuously or intermittently sterilize the exposed surfaces / areas of the device. This active sterilization may be accomplished by a variety of mechanisms, including, application of heat, RF, microwave, ultrasound, ultraviolet radiation or other energy capable of sterilizing the device or dislodging any problematic Biofilm that may form. The active sterilization may also employ the pumping of a sterilizing chemical from an attached drug reservoir, the use of electricity or freezing temperatures or any other mechanism for either inhibiting, killing or dislodging any infectious material in contact with the implant. One major advantage of this design is that through the use of a small, battery powered or inductively powered sterilization element, the implanted catheter or device can be effectively sterilized without requiring the standard removal surgery, waiting period, then replacement of the infected device. This is expected to translate into greatly improved outcomes (particularly for devices where infection may be catastrophic, ie a prosthetic knee or hip), greatly improved costs, and greatly improved longevity of susceptible devices (ie IV ports, etc.).

An urethral sealing device comprising first and second body portions selectively attacheable to one another to form a unitary element including a first catheter lumen extending therethrough between proximal and distal ends of the unitary element wherein, when the sealing device is in an operative position, the distal end is positioned within a urinary bladder and a sealing element extending radially outward from the unitary element so that, when the sealing device is in the operative position, the sealing element engages one of a wall of the urethra and a wall of the urinary bladder around an orifice at which the urethra opens into the urinary bladder to seal the urethra.

The present invention relates to an implantable apparatus for obtaining urinary control and emptying of the urinary bladder, thereby preventing from or treating involuntary urinary retention. In general terms, the apparatus comprises an expandable member adapted to be implanted inside the urinary bladder of the patient for discharging urine, and a control device for controlling the volume of the expandable member. The control device is adapted to be connected to the expandable member through the wall of the urinary bladder.

Provided herein are implantable or insertable biomedical devices comprising a substrate and a collagen inhibitor on or in said substrate, and methods of treatment using the same. In some embodiments, the device is a urethral, ureteral, or nephroureteral catheter or stent. Kits comprising the same are also provided.
