Abstract:
A system for supporting the urethra using an introducer needle, the ends of which are flattened and which have openings therethrough, a handle having a latch mechanism which engages the opening in the flattened portion of the first end of the introducer needle, an implant, and a connector joining the end of the implant to the flattened portion of one of the ends of the introducer needle. These components are used to draw the implant into position, either through vaginal or abdominal incisions, to form a U-shaped loop beneath the urethra. The ends of the implant are adjusted to provide proper support for the urethra. The implant can have slits that open under applied tensile force.
Abstract:
An introducer device comprising: an introducer needle having a proximal end and a distal end and a handle having a needle receiving end. The handle can be adapted to receive said distal end of said introducer needle such that said introducer needle is selectably detachably coupled to said handle. A connector for attachment to an implant strip can have an arm having a hole therethrough and an introducer needle including a connection portion having a barb. It can comprise a central portion; a first arm pivotally mounted to the central portion and having a first projection and a second projection extending therefrom. A second arm can be pivotally mounted to the central portion and having a first hole and a second hole defined therein. The first and second holes can be positioned so that when the first arm pivots toward the second arm, the first and second projections are received in the first and second holes. A tube portion can extend from said central portion and define a tube aperture therein. The tube aperture can be adapted to receive the barb such that the connector can be selectably detachably coupled or permanently affixed to the introducer needle.
Abstract:
An apparatus is disclosed for guiding a medical instrument to a predetermined target location within the periurethral tissues of a patient. The apparatus directs the instrument along a predetermined path with respect to the patient's urethra (250) and limits penetration of the instrument to a predetermined depth. The disclosed embodiment comprises an apparatus for implanting inflatable prostheses (220) within the periurethral tissues to coapt the urethra (250) and thereby manage incontinence. A method for effecting coaptation of a urethra (250) of a patient is also disclosed. According to this method, a pair of working channels are formed within the periurethral tissues, and an inflatable prosthesis (220) is introduced into each working channel. The prostheses (220) are inflated only after both working channels have been formed, and preferably after both prostheses (220) have been positioned within their respective working channels. The inflated prostheses (220) confront the urethra (250) and effect coaptation of the urethra (250).
Abstract:
A medical retrieval device includes a handle (12), two gear racks (26a, 26b) movably mounted to the handle (12) for longitudinal movement, and a pinion (52) rotatably mounted to the handle (12) so as to engage the two gear racks (26a, 26b). Rotation of the pinion (52) moves the gear racks (26a, 26b) in opposite directions. A basket (16) has at least three legs (70a-d), an adjacent two of the legs (70a-d) being connected to one of the gear racks (26a, 26b), and the remainder of the legs being connected to the other gear rack such that rotation of the pinion (52) displaces the two legs in a first direction and displaces the remainder of the legs in a second direction. Thus rotation of the pinion (52) articulates the basket (16).
Abstract:
A medical retrieval device includes a handle and a hollow sheath extending forward from the handle. A slide is attached to the handle for longitudinal movement along a path between a rearward location and a forward location. A rotary actuator having an axis of rotation generally transverse to the path of movement of the slide is mounted to the slide for rotational movement with respect thereto. A basket having at least three legs is located at a forward end of the sheath. Two adjacent basket legs are connected to a first side of the rotary actuator, and the remaining basket legs are connected to the opposite side of the rotary actuator such that rotation of the rotary actuator displaces the two legs in a first direction with respect to the sheath and displaces the remainder of the legs in a direction opposite the first direction. The basket is retracted within a forward portion of the sheath when the slide is in the rearward location, and the basket is extended forward of the forward end of the sheath when the slide is in the forward location. Thus longitudinal movement of the slide extends and retracts the basket, and rotation of the rotary actuator articulates the basket.

Abstract:
A drain assembly (14) for a fluid collection container (10) includes a housing (22) attached to the container and defining a cavity therewithin. A stop (42) is located within the cavity and is fixed relative to the housing. A switch (24) having a closure member formed thereon is mounted within the cavity for rotary movement relative to the housing. In a disclosed embodiment the switch has a tab (52) extending through the housing to facilitate rotation of the switch from outside the housing. A flexible, resilient tube (10) in fluid communication with the interior of the fluid collection container has a portion disposed within the cavity and extending between the stop and the closure member of the switch. The tube is configured so that fluid discharged from the lower end (33) of the tube is discharged through an opening (41) in a lower portion of the housing. When the switch is rotated in one direction, the tube is compressed between the stop and the closure member, thereby preventing fluid flow through the tube. When the switch is rotated in the opposite direction, the closure member rotates away from the stop so as to permit the tube to open, thereby permitting fluid flow to be discharged from the fluid collection container through the tube.
