摘要： Several embodiments of an endourethral prosthesis, assembly, and attendant methods are provided for patients presenting with lower urinary tract symptoms (LUTS) or urinary retention. The endourethral prosthesis includes a reversibly expandable element disposed circumferentially about, and longitudinally along a tubular member adapted to receive urine. The tubular member is positionable within a lower urinary tract such that the reversibly expandable element operatively engages a structure of the lower urinary tract so as to prevent migration of the prosthesis so positioned. The reversibly expandible element is in non-reversible fluid communication with the tubular element for selective expansion thereof, the reversibly expandible element is further operatively engagable so as to discharge fluid non-reversibly received from the tubular member exterior to same.

摘要： Novel intravascular, ultrasonic imaging catheters are provided which utilize thin layers of a flexible plastic material, such as PVDF, which can be spot polarized in active regions which are to serve as piezoelectric transducers. Thin layer metallic electrodes are deposited on opposing surfaces of these active regions. Strips of the appropriately configured material also having shielding and backing and/or core forming portions are spiral wound into a completed catheter. Alternatively, the catheters are fabricated from extruded PVDF tubing which may be formed around a central core which carries those electrodes which are to contact the inner surface of the extruded tube.

摘要： The present invention relates to an apparatus which determines the distribution of the attenuation slope coefficient on a real-time basis using the center frequency shift. In one embodiment, the phase difference between a received signal and a reference signal is determined using EXCLUSIVE OR gates or an inverse trigonometric relation stored in a ROM. The phase difference is input to a differentiator which outputs the center frequency shift of the received signal on a real-time basis. The center frequency shift is input to another differentiator which outputs the attenuation slope coefficient. In other embodiments, the received signal is distributed into received signal bands, having different center frequencies, and signal characteristics of the received signal bands are averaged to remove virtually all effects of spectrum scalloping in the time domain. Thus, the attenuation slope coefficient is obtained without the effects of spectrum scalloping using simple hardware and without Fourier transformation.
