A system and a method of positioning a wire guide are provided. The method includes inserting a wire guide in a first configuration into a lumen of a catheter, distally advancing the wire guide to a distal portion of the lumen so that a distal end of the wire guide is distal to an opening in a wall of the catheter and advancing a distal portion of the wire guide through the opening by distally advancing the distal portion relative to the catheter so that the distal end remains in the lumen as the distal portion of the wire guide extends out of the opening. The method includes advancing the distal portion of the wire guide further out of the opening so that the distal end exits through the opening so that the distal portion is distal to the distal end of the wire guide in a second configuration.

A medical sphincterotome and a method of its use are described. The sphincterotome has structural elements that are capable of directing a wire guide through a selected body passageway. One structural element includes a distal port and deflection member that can deflect the wire guide into the desired passageway. Another structural element includes an offset nose-shaped end that can bend towards a passageway desired to be blocked. The wire guide is prevented from entering the blocked passageway, thereby enabling the wire guide to cannulate the desired passageway. The sphincterotome also includes a cutting wire to access a patient's sphincter and perform various other medical procedures.

The present embodiments provide a clip device for engaging tissue. The clip device comprises at least first and second arms having proximal and distal ends. The clip device comprises an open state when a spring member is in a compressed state in which the distal end of the spring member is spaced further apart from the distal ends of the first and second arms. In the open state, the distal ends of the first and second arms tend to be spaced apart from each other. Further, the clip device comprises a closed state when the spring member is in a relaxed state in which the spring member is biased to extend distally and the distal ends of the first and second arms are adjacent to each other and may engage tissue and promote hemostatis. A delivery system and methods for deploying one or more clip devices also are provided.

Clip devices and methods of delivery and deployment

A method and device for removing tissue from a patient during a biopsy procedure utilizing a biopsy collection device are provided. The biopsy collection device includes a body portion configured for attachment to an endoscope and a receptacle portion configured to retain a portion of tissue removed from a target site during the biopsy procedure. The biopsy collection device further includes a passageway configured to receive a biopsy sampling device, such as a pair of forceps, passing through the endoscope to the target site.

Biopsy collection device

An apparatus and method comprising at least one intragastric member made of a digestive-resistant or substantially indigestible material that is introduced into a bag located in the gastric lumen of a mammal for the treatment of obesity. One or more intragastric members are loaded into a delivery tube in a partially compacted first configuration and delivered to an overtube. The overtube includes a proximal end, a distal end and a lumen configured to receive the intragastric members in the first configuration for delivery to the bag located in the gastric lumen wherein the intragastric member is expanded to a second configuration. The apparatus further comprises a constraining element engaged with the bag to secure the intragastric member upon delivery into the gastric lumen.

Intragastric bag for treating obesity

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., can be introduced to perform a second medical operation without a traditional over-the-wire exchange being required. In another example of the method, a prosthesis, such as a valve or stent, is placed within the work site coupled to a wire guide which is remotely disconnected within the work site and a secondary device, such as a dilation balloon or second prosthesis, is introduced into the work site after the first delivery system is removed.

System and method for introducing multiple medical devices

An end cap for an endoscope. The end cap is configured to allow the endoscope to be introduced into a patient body by a short-wire type of operation.

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.

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 direction ( ) and under a first pressure, while collapsing in response to fluid flowing in a second direction where the pressure that exceeds that of the first direction or pressure. One aspect of the invention includes an esophageal anti-reflux expandable prosthesis wherein the sleeve is adapted to invert back through the tubular stent frame to permit belching or vomiting (fluid or materials under a third, significantly higher pressure). Another aspect of the invention includes a tubular drainage stent ( ), such as a biliary or urethral stent in which the sleeve opens to permit passage of fluids, then collapses to prevent retrograde flow.
