  • Publication number: 20200146799
    Abstract: An inflated implant, such as an attenuation device, previously implanted in a urinary bladder can later be removed according to a number of different methods. Preferably, removal is accomplished transurethrally. In one embodiment, removal is accomplished by reducing the inflated implant from an enlarged profile to a reduced profile so that it may be withdrawn transurethrally by a removal system. The removal system can be configured differently depending upon whether reduction from the enlarged profile to the reduced profile is accomplished by deflation, compression, and/or other ways.

  • Patent number: 8858460
    Abstract: Measurement of a patient's leak point pressure in the bladder can be taken by a processor in communication with a pressure catheter in the bladder. When leakage occurs pressure data points can be recorded. In some embodiments, the peak pressure can be determined based on pressure data points measured during a set time just before receiving a clinician input indicative that leakage has occurred.

  • Patent number: 8298132
    Abstract: Disclosed herein are methods of treating a patient with benign hypertrophy of the prostate, comprising providing a compressible attenuation device that is moveable from a first, introduction configuration to a second, implanted configuration and attenuating a pressure change within the bladder by reversibly changing the volume of the attenuation device in response to the pressure change. In one embodiment, the attenuation device is advanced percutaneously into the bladder. In another embodiment, the attenuation device is positioned within the bladder to inhibit a decrease in compliance of the bladder wall as a consequence of the benign hypertrophy of the prostate.

  • Patent number: 5561860
    Abstract: An improved shirt/sweater which is reversible and comprised of two different sides, each having fabric of different color, pattern and/or texture. The sleeves are slightly tapered and extended in length over the conventional sleeve lengths so that when simply rolled up they can automatically serve as cuffs (18). The rolled-up cuff feature, while providing extra aesthetic contrast in color, pattern and/or texture, also eliminates the need for making and using separate cuffs (12) which in any case render the extra thick sleeves (because they are two layered) unattractive by necessitating drastic tapering to accommodate them. The shirts/sweaters can further be cut in such a fashion, e.g., in the collar (22) and bottom rim (20) as to simply yet elegantly provide contrast in color, pattern and/or texture in a stylish, comfortable form.
