US Patent:

20030236495, Dec 25, 2003

Filed:

May 12, 2003

Appl. No.:

10/436452

Inventors:

Kenneth Kennedy - Clemmons NC, US

International Classification:

A61M029/00

US Classification:

604/097020, 606/194000

Abstract:

A balloon catheter including an inflatable balloon affixed to a catheter. The proximal end of the balloon is affixed to the outer wall of the catheter so as to provide an air tight seal there between. A slip joint is formed between the distal end of the catheter and the distal end of the balloon to permit the distal end of the balloon to axially move or translate with respect 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, thereby preventing transverse creases from forming in the surface of the balloon and preventing the catheter from bowing. Alternatively, the catheter may be terminated so as to not contact the distal end of the balloon, or the catheter can be segmented so that separate catheter parts are connected to each end of the balloon, thereby eliminating the slip joint altogether.

Abstract:

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, thereby preventing transverse creases from forming in the surface of the balloon and preventing the catheter from bowing. The stiffening member provides alignment and lateral support to the distal end of the balloon.

International Classification:

A61B006/00

US Classification:

600433000

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., 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.

Abstract:

Devices and methods for detachably engaging an insertion section of an endoscope and selectively articulating an endoscopic surgical access channel are provided. A device comprises an articulating main body having a stationary first body, an articulatable second body, and coupler having a mounting member and an articulation link member configured to articulatively couple the second body to the first body. The stationary first body has a distal end, a proximal end, and a first longitudinal axis. The articulatable second body has a proximal opening and a distal opening defining an accessory channel member passageway, the distal opening having a second longitudinal axis oriented toward a space exterior to the first body distal end, wherein the second body longitudinal axis is capable of articulating relative to the first body longitudinal axis. The devices and methods, as taught herein, provide control over the position and/or orientation of a diagnostic, monitoring, scope, sewing device, cutting device, suturing device, forceps, grabbing device, instrument, or other tool within the visual field beyond the distal opening of the endoscope.
