Implant with high vapor pressure medium
InactiveUS20100222802A1Promote recoveryImprove the immunitySuture equipmentsUrinary bladderHydrostatic pressureProduct gas
An implant for use in a human or animal body can include a flexible housing with an outer wall and having a chamber therein. The implant can have at least one high vapor pressure medium within the chamber. The at one high vapor pressure medium can have a combined vapor pressure equal to or greater than about the average value of the hydrostatic pressure of the implantation site plus the skin tension of the housing minus the gas tension of the dissolved gasses present at the implantation site.

Ureteral stent system apparatus and method
A stent having an elongate tubular configuration is formed of a plurality of elongate elements interwoven or braided to form a tubular configuration. The elements may be relatively strong and rigid, but movable relative to each other within the weave or braid in order to provide the stent with generally soft characteristics. The elements may be formed of different materials, such as an absorbent material permitting the stent to be doped with materials such as drugs and chemicals. Even the absorbency can be controlled and varied to provide a predetermined time-release of the absorbent.

It is a general object of the invention to provide a method of effecting tissue repair or replacement using a biomaterial. It is a specific object of the invention to provide a biomaterial suitable for use as a stent, for example, a vascular stent, or as a conduit replacement, as an artery, vein or a ureter replacement. The biomaterial can also be used as a stent or conduit covering or lining. The present invention relates to a method of repairing, replacing or supporting a section of a body tissue. The method comprises positioning a biomaterial at the site of the section and bonding the biomaterial to the site or to the tissue surrounding the site. The bonding is effected by contacting the biomaterial and the site, or tissue surrounding the site, at the point at which said bonding is to be effected, with an energy absorbing agent. The agent is then exposed to an amount of energy absorbable by the agent sufficient to bond the biomaterial to the site or to the tissue surrounding the site.

Method and apparatus for automated active sterilization of fully implanted devices
InactiveUS20150011928A1Effective sterilizationPromote resultsUrinary bladderStentsUltravioletProsthetic knee
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 all 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 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.).

Reconstruction of urological structures with polymeric matrices
A method for repairing defects and reconstructing urothelial structures in vivo has been developed using a fibrous, open synthetic, biodegradable polymeric matrix which is configured to provide the desired corrective structure. The matrix is shaped to correct the defect, then implanted surgically to form a scaffolding for the patient's own cells to grow onto and into. The implantation of the matrix initiates an inflammatory reaction, resulting in urothelial cells, endothelial cells and mesenchymal cells, to migrate into the matrix. The polymer forming the matrix is selected to be biocompatible and degradable in a controlled manner over a period of one to six months, in the preferred embodiment. A preferred material is a poly(lactic acid-glycolic acid) in a fibrous form, such as a woven or non-woven mesh. Examples demonstrate the repair of defects in bladder in rabbits.
