Abstract: Disclosed is a pressure sensitive prosthesis that includes a tubular member having a passageway extending therethrough and a sleeve attached about one end of the tubular member. The sleeve functions as a one-way valve to permit fluid flowing through the sleeve lumen in a first, distal direction and under a first pressure, while collapsing in response to fluid flowing in a second direction when the pressure thereof exceeds that of the first direction or pressure. One aspect of the invention includes a first opening and a second opening configured for allowing fluid flow from the passage to the lumen in the first direction.

Abstract: A method and apparatus for introducing a first elongate medical device and short wire guide that are coupled together into a work site and remotely disconnecting them within the work site such that a secondary device comprising a catheter member can be introduced over the wire guide to the work site, and/or a second wire guide can be introduced to the work site via a passageway of the primary access device. A system of indicia, such as radiopaque or viewable markers, permit the operator to monitor the relative alignment of the devices within the work site to determine when uncoupling has occurred. In one example of the method, a wire guide and primary access device (e.g., a sphincterotome) is coupled to the wire guide and introduced via a duodenoscope into the biliary system. After performing a first medical operation, the devices are uncoupled with the wire guide being left within the biliary system such that a secondary access device, such as a balloon, biopsy device, stent delivery catheter, dilator, etc.

Abstract: A stent introducer apparatus includes a handle having a housing and a rotatable reel. An inner stent carrier having a proximal end and a distal end is provided, with the proximal end being connected to the housing of the handle. An outer sheath movably disposed about the inner stent carrier and having a proximal end and a distal end is provided, with the proximal end being connected to the reel of the handle. Rotation of the reel relative to the housing peels the outer sheath away from the inner stent carrier so as to move the outer sheath proximally relative to the inner stent carrier, thereby exposing the distal end of the inner stent carrier. The inner stent carrier has a stent carrying portion at its distal end to carry a stent that is deployed when the distal end of the inner stent carrier is exposed.

Abstract: Over-the-scope stent introducers for detachably engaging at least a portion of the outside of an endoscope insert and for delivering a stent are provided. Embodiments include an inner member having a distal first end portion and a proximal second end portion and openings defining a channel. The inner member includes an outer surface, inner endoscope engaging surface, and stent abutting restraint disposed at the first end portion. Embodiments also include an outer member having a distal section and proximal section having openings defining a passageway sized to slideably receive at least a portion of the inner member, and a stent carrying inner chamber disposed at the distal section passageway and being configured to releasably contain a stent. In alternative embodiments, the inner and outer members are elongated to dispose substantially concentrically over a majority of an endoscope insert.

Abstract: A system is provided for preventing the accumulation of cumulative matter from clogging a stent, such as a plastic tubular drainage stent for use in the biliary system. The system includes a stent having one or more magnetically reactive objects moveably disposed therein and an actuation device, such as a glove, having one or more magnets thereon. When the actuation device is waived near the one or more magnetically reactive objects of the stent, it actuates them by manually manipulating the one or more magnetically reactive objects of the stent by attracting or repelling them such that they contact the stent walls dislodging cumulative matter attached thereto. As a result of the system, the stent is able to remain resident within the patient for an extended period of time before becoming clogged and needing to be replaced.

Abstract: A balloon catheter is provided that may be used to maneuver around tortuous body lumens. The balloon catheter comprises one or more balloons disposed about a tip of the shaft. Each balloon includes a dedicated lumen to allow inflation of each balloon independent of the others. Inflation of a balloon causes the shaft tip to deflect in a direction that is oriented opposite of the inflated balloon. The bent orientation of the shaft tip allows the catheter and a guide wire to be maneuvered through tortuous body lumens.

Abstract: Over-the-scope stent introducers for detachably engaging at least a portion of the outside of an endoscope insert and for delivering a stent are provided. Embodiments include an inner member having a distal first end portion and a proximal second end portion and openings defining a channel. The inner member includes an outer surface, inner endoscope engaging surface, and stent abutting restraint disposed at the first end portion. Embodiments also include an outer member having a distal section and proximal section having openings defining a passageway sized to slideably receive at least a portion of the inner member, and a stent carrying inner chamber disposed at the distal section passageway and being configured to releasably contain a stent. In alternative embodiments, the inner and outer members are elongated to dispose substantially concentrically over a majority of an endoscope insert.
