Patent number: 8206320Abstract: 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.Type: GrantFiled: July 29, 2004Date of Patent: June 26, 2012Assignee: Cook Medical Technologies LLCInventors: Stephen E.

Patent number: 7976496Abstract: A balloon catheter including an inflatable balloon affixed to a catheter. The proximal end of the balloon is affixed to the distal end of the catheter so as to provide an air tight seal there between. A stiffening member extends distally of the distal end of the catheter and forms a slip joint connection with the distal end of the balloon to permit the distal end of the balloon to axially move or translate relative to the distal end of the catheter. The slip joint allows the axial length of balloon to change during inflation or deflation without transferring tensile or compressive forces between the balloon and the catheter. A balloon folding control mechanism is disposed about the portion of the stiffening member traversing the interior of the balloon, and is configured to promote refolding of the balloon into a predetermined and desired folding configuration upon deflation.Type: GrantFiled: July 7, 2008Date of Patent: July 12, 2011Assignee: Cook Medical Technologies LLCInventors: Kenneth C.
