Patent number: 8211087Abstract: A method and apparatus for releasably securing a wire guide to an elongate medical device for introduction into a work site with the bodily lumen of a patient. An elongate engagement member is configured to engage the wire guide while it is coupled to the elongate medical device and is configured so as to prevent relative movement between the wire guide and the elongate medical device.Type: GrantFiled: December 7, 2004Date of Patent: July 3, 2012Assignee: Cook Medical Technologies LLCInventors: Matthew P.

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.

Publication number: 20110054520Abstract: A method of occluding a fistula in a patient is provided. The method includes inserting a placement member having a coupling structure, such as a wire guide having a loop at one end, through the primary opening of a fistula and at least partially into the fistula tract; connecting the coupling structure to a medical device, such as a plug, graft, or other occluding member; and inserting the medical device into the fistula by pulling the placement member through the fistula until the medical device contacts the interior wall of the fistula. Medical devices and systems for occluding fistulas are also provided.Type: ApplicationFiled: November 8, 2010Publication date: March 3, 2011Applicant: Wilson-Cook Medical Inc.Inventors: Stephen E.

Patent number: 7731652Abstract: A medical device for allowing a physician to unhand a scope or other instruments while maintaining control of the scope or other instruments during a medical procedure. The medical device includes at least one docks and a harness for attaching the dock to the physician's body. The harness can be adjustable, or sized to fit a specific physician. During a procedure, a physician outfitted with the medical device can place a scope and/or other instrument in the dock(s). Once the scope and/or other instrument is placed in the dock(s), the physicians hands are free to perform other procedures, while the physician continually controls the relative position of the scope with respect to the physician or the patient.Type: GrantFiled: May 13, 2005Date of Patent: June 8, 2010Assignee: Wilson-Cook Medical Inc.Inventors: Vihar C.

Patent number: 7141050Abstract: A physician access system comprising a catheter for use with an endoscope, the catheter including a wire guide lumen having a plurality of access ports disposed along an intermediate portion thereof to permit the insertion of a wire guide at different locations. The location of each access port corresponds to a specific length of the catheter exiting from the distal end of the endoscope. The access ports are located so that at least one of the access ports will be positioned near the endoscope handle when the distal end of the catheter, and any operational tool attached thereto, has been extended a short distance past the distal end of the endoscope. A physician may select the access port which best allows simultaneous control of the wire guide and the endoscope depending on the length of the catheter that the physician desires to have extend from the end of the endoscope.Type: GrantFiled: October 17, 2003Date of Patent: November 28, 2006Assignee: Wilson-Cook Medical Inc.Inventors: Stephen E. Deal, David F. Waller
