An endourethral device is provided having an elongate member having proximal and distal segments, the elongate member positionable within a lower urinary tract so as to at least partially traverses a prostatic urethra. A proximal anchor, adapted to abuttingly engage portions of a bladder neck so as to at least proximally anchor the device, is supported at least indirectly by the proximal segment of said elongate member. The proximal anchor includes bladder engaging elements radially extending from the proximal segment of said elongate member, urine being freely dischargable about at least the proximal segment so as to substantially bathe the bladder neck therewith.

Endourethral device and method

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.

Urinary flow control device and method

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.

Apparatus and method for retrieving a remotely located device equipped with a magnetic coupler is provided. The apparatus includes a magnetic coupling carried at an end of an elongate member for attracting the magnetic coupler of the remotely located device, and aligning the magnetic coupler with the magnetic coupling. A frictional engagement device, substantially housing the magnetic coupling therein, is adapted for trapping the magnetic coupler therein such that a retrieval force applied to the apparatus is transferred to the remotely located device via the frictional engagement device to thereby facilitate sure retrieval of the device as by magnetic mechanical entrapment.

Endourethral device  and method

A urethral profile apparatus, assembly and appurtenant methodology is provided. The apparatus includes an elongate member having proximal and distal ends, the proximal end including a probe. The probe is selectively positionable within a urethral passageway by axial translation of the elongate member via the distal end, with the probe dimensioned so as to indicate constrictures of the urethral passageway.

Urethral profiling device and methodology

An endourethral device including proximal and distal anchor assemblies selectively spaced apart by a device body is provided. The proximal anchor assembly is adapted to abuttingly engage at least portions of a bladder neck so as to at least proximally anchor said device, the distal anchor assembly being adapted to engage at least portions of a bulbous urethra so as to at least distally anchor said device. The body extends between the proximal and distal anchors assemblies, the device being adapted such that the anchors are selectively spaced apart for fixed positioning within a lower urinary tract in furtherance of a portion of the body at least partially traversing a prostatic urethra.

A diagnostic urethral 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 that is 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 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 and a second 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.

Diagnostic urethral assembly and method

An intravascular device, such as a sheath, and methods for use thereof for selective alternate positioning of other intravascular devices having predetermined sizes in a distal vascular region of the body of a patient. The intravascular selection sheath comprises a tubular body having proximal, intermediate and distal sections and a lumen extending therethrough. The portion of the lumen in the distal section can be occupied by only one of the other intravascular devices of the predetermined sizes at a given time. The portion of the selection sheath lumen in the intermediate section can be occupied by at least two intravascular devices of the predetermined sizes in a side by side relationship. In operation, the two other intravascular devices occupy positions in the lumen in the intermediate section of the selection sheath. First, one of the intravascular devices can be advanced into the lumen in the distal section of the selection sheath and then withdrawn back into the intermediate section. Next, the other of the intravascular devices can be advanced from the intermediate section into the distal section of the selection sheath, thereby allowing for multiple diagnostics, therapies, or other procedures to be performed alternatively. The other intravascular devices that occupy positions in the sheath lumen can be exchanged for yet further intravascular devices. This selection sheath geometry can also be incorporated in intravascular devices that provide therapeutic and/or diagnostic functions.

Sheath for selective delivery of multiple intravascular devices and methods of use thereof

An apparatus and method for placement of a tubular body in the urethra. The tubular body includes a proximal portion adapted for placement toward a bladder end and bladder neck end of the urethra and a distal portion opposite from the proximal portion. A sensor component located on the tubular body is responsive to a feature of the urethra and outputs a first signal indicating proper placement of the proximal portion of the tubular body relative to the bladder and bladder neck. Preferably, an insertion tool is used during positioning of the urethral apparatus. The insertion tool is coupled to the distal end of the urethral apparatus and is used to push the urethral apparatus proximally in the urethra. The first signal can be transmitted from the urethral apparatus through the insertion tool from which it is perceivable by the person positioning the urethral device. Upon proper placement, the insertion tool is decoupled from the urethral apparatus and withdrawn leaving the urethral apparatus in place in the urethra with the proximal portion properly positioned relative to the bladder neck and bladder.

Urethral apparatus with position indicator and methods of use thereof

A device that comprises a tubular-shaped body that is insertable into a body passageway or cavity, in particular the urethra, and that has an exterior surface having one or more anchors located thereon that aid in movement of the device with a minimum of trauma during placement and that aid in securing the device within the passageway or cavity during use. The device may be inserted into either the urethra, bladder neck, or bladder. The anchors can vary in height, length, number, compressiveness, axial placement, material characteristics, and helix angle. According to a further aspect, the one or more anchors are in the form of partial spiral helixes that function to move and secure the device within the human urethra. The partial spiral helixes have structures that allow for the longitudinal movement of the device during positioning procedures.
