Inventors:

Tyler E. McLawhorn - Winston-Salem NC, US

Assignee:

Cook Medical Technologies LLC - Bloomington IN

International Classification:

A61B 17/08
A61B 17/10

US Classification:

606151, 606142

Abstract:

The present embodiments provide a tacking device for engaging tissue, which may be useful for coupling a graft to tissue or facilitating closure of a bodily opening. In one embodiment, the tacking device comprises a main body having proximal and distal ends, and further comprises at least one proximal deployable member and at least one distal deployable member, each having contracted and expanded states. The proximal deployable members extend proximally from the proximal end of the main body, while the distal deployable members extend distally from the distal end of the main body. In one embodiment, a hook member extends from at least one of the proximal deployable members. In use, the hook member may be engaged, for example, using a loop member coupled to a stylet, thereby facilitating controlled release of the tacking device and allowing repositioning of the tacking device after at least partial deployment of the distal deployable members.

International Classification:

A61B 17/08

US Classification:

606153, 24547

Abstract:

The present embodiments provide medical apparatuses and methods for rapidly forming an anastomosis between two viscera. The medical apparatus generally comprises affixing a clamp to an elongate member. The method generally comprises positioning and then deploying the medical apparatus between and within two stomas via an elongate member.

Appl. No.:

13/086097

Inventors:

Vihar C. Surti - Winston-Salem NC, US
Tyler Evans McLawhorn - Winston-Salem NC, US

Assignee:

Cook Medical Technologies LLC - Bloomington IN

International Classification:

A61B 17/08

US Classification:

606153

Abstract:

Medical system and methods are provided for forming an Anastomosis, such as an intestinal bypass anastomosis for treatment of obesity or diabetes. The medical devices and methods are minimally invasive and reduce complications. One embodiment of the method includes forming a first opening in the first section and forming a second opening in the first section. A proximal portion of the second section is moved to a position adjacent the first opening, and a distal portion of the second section is moved to a position adjacent the second opening. In this manner, an intermediate portion of the second section extends along the first section and an anastomosis can then be formed between the first section and the second section.

International Classification:

A61B 17/10
A61B 17/08

US Classification:

606139, 606151

Abstract:

The present embodiments provide apparatus and systems suitable for coupling a graft member to tissue. A wire having a proximal end and a distal end are provided, each having a delivery state suitable for delivery and further comprising a deployed state. In the deployed state, the distal end is configured to engage tissue at a first location, and the proximal end is configured to engage the graft member to secure the graft member to the tissue. Optionally, a loop member may be provided for receiving a suture for further securing the graft member to the tissue. The present embodiments may also be used without a graft member to close openings in tissue.

International Classification:

US Classification:

606139, 606232

Abstract:

The present embodiments provide a tacking device for engaging tissue, which may be useful for facilitating closure of a bodily opening. The tacking device comprises a main body having proximal and distal ends, and at least one distal deployable member having contracted and expanded states that extends distally from the distal end of the main body. In use, after the distal deployable members have been at least partially expanded at a preliminary location, the distal deployable members may be contracted to permit repositioning at a different, final location. In one exemplary method, at least two tacking devices may be deployed to at least partially surround an opening in tissue, and a suture coupled to the first and second tacking devices may be actuated to facilitate closure of the opening.
