摘要： An intravascular device such as an introducer sheath or a balloon catheter, and methods for use thereof, comprising an elongate member having a proximal end and a distal end and a first lumen and a second lumen. The first lumen communicates with a first proximal opening at the proximal end of the elongate member and with a distal opening at the distal end of the elongate member. The second lumen terminates distally and communicates with the first lumen at a location proximal of the first distal opening and has a proximal opening located proximally therefrom. One or more perfusion openings may be located in the device to allow blood flow therethrough. The proximal opening of the second lumen may be located distally of the proximal opening of the first lumen. A balloon may be located on a distal portion of the elongate shaft.

摘要： A diagnostic urethral assembly is provided. The assembly includes an elongate body having a fluid passageway and an elongate support member selectively positionable within the fluid passageway of the elongate body. The elongate body has a radially responsive wall segment, the elongate body being positionable within a lower urinary tract such that the radially responsive wall segment is adjacent a prostatic urethra. The elongate body is adapted to be in fluid communication with a bladder. The assembly has a first operably selective condition wherein the elongate support member is translatable relative to the elongate body so as to permit sequential and incremental radial compression of the radially responsive wall segment by the prostatic urethra in furtherance of defining architecture associated with the prostatic urethra. The assembly further has a second operably selective condition wherein fluid distally introduced into the elongate body radially expands the radially responsive wall segment into conforming engagement with the prostatic urethra in furtherance of obtaining a mold of same.

摘要： Embodiments of adjustable length intraurethral devices intended for patients with Lower Urinary Tract Symptoms (LUTS) are disclosed. These devices are to be placed within the human urethra and in communication with the bladder. Each device is easily adjustable to accommodate the prostatic length and sphincteric anatomy of the patient. Devices are stabilized in the urethra by two anchoring elements. The first anchor is fluid filled and positioned at the outlet of the bladder, and a second anchor is mechanical and is located at the bulbous urethra. These are separated by a structure which selectively supports a portion of the urethra from closing without restricting the portion of the urethra in the region of the external sphincter. These embodiments provide for the regulation of the flow of urine from the bladder by the natural control of the external sphincter when the user desires.

摘要： A temporary stent for supporting a region of a vessel in a body comprising a stent portion and an actuator portion and methods for the use and manufacture thereof. The stent portion is comprised of an elongate perfusable vessel supporting portion adapted to be configurable between a reduced size for placement in the vessel and removal therefrom and an expanded size for structurally supporting the vessel and perfusable end portions connected to and forming ends of the vessel supporting portion and adapted to allow fluid flow therethrough. The actuator portion includes a proximal end extending out of the body and a distal end connected to the stent portion and operable by manipulation at the proximal end thereof to configure the support portion into a reduced size and an expanded size.

摘要： A urinary flow control device having a bladder responsive flow control assembly operatively engaged with an elongate member having proximal and distal ends, and a lumen capable of discharging urine therethrough is provided. The flow control assembly includes first and second fluid containing compartments adapted to be in fluid communication. The flow control assembly is adapted to receive and contain urine from a bladder so as to impinge upon the first fluid containing compartment. The flow control assembly is responsive to increased bladder pressure such that fluid is displaced from the first fluid containing compartment to the second fluid containing compartment to thereby permit select passage of received urine to the lumen of the elongate member for discharge therethrough. A method of controlling urinary flow is likewise provided.
