Interlocking Tissue Anchor Apparatus And Methods

US Patent:
7601159, Oct 13, 2009
Filed:
Sep 30, 2004
Appl. No.:
10/955244
Inventors:
Richard C. Ewers - Fullerton CA,
Tracy D. Maahs - Rancho Santa Margarita CA,
Cang C. Lam - Irvine CA,
Vahid Saadat - Saratoga CA,
Chris Rothe - San Jose CA,
Assignee:
USGI Medical, Inc. - San Clemente CA
International Classification:
A61B 17/03
US Classification:
606139, 606232
Abstract:
Interlocking tissue anchor apparatus and methods are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably disposed through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. Anchor assemblies can be delivered via the tissue manipulation assembly into or through the tissue. The anchors can incorporate various temporary interlocking features or spacing elements between one another to ensure that an anchor is not prematurely ejected from the needle assembly. This allows the anchor assembly to be advanced distally as well as withdrawn proximally within a deployment sheath while avoiding inadvertently ejecting an anchor.

Methods And Apparatus For Revision Of Obesity Procedures

US Patent:
2007017, Aug 2, 2007
Filed:
Jan 27, 2006
Appl. No.:
11/342288
Inventors:
John Cox - Rancho Santa Margarita CA,
Tracy Maahs - Rancho Santa Margarita CA,
Richard Ewers - Fullerton CA,
Eugene Chen - Carlsbad CA,
Cang Lam - Irvine CA,
Lee Swanstrom - Portland OR,
Assignee:
USGI Medical Inc. - Santa Clara CA
International Classification:
A61B 17/138
US Classification:
128898000
Abstract:
Methods and apparatus for the endoluminal revision of previously performed obesity procedures which have failed are described. One or more endoluminal instruments may be advanced per-orally into the previously formed failed pouch where a number of different procedures can be performed. One or more tissue folds can be formed and secured to reduce the size of the pouch, or the stoma connecting the pouch to the intestinal tract can be reduced in size using endoluminally deployed tissue anchors. These procedures can be performed entirely from within the pouch lumen or upon the exterior surface of the pouch via transgastric entry of the instruments into the peritoneal cavity of a patient. Alternatively, the interior tissue within the pouch can be injured or sclerosed to shrink the pouch lumen. In another alterative, a length of the Roux limb can be shortened endoluminally to create a malabsorptive region.

Devices And Methods For The Endolumenal Treatment Of Obesity

US Patent:
2013021, Aug 22, 2013
Filed:
Feb 6, 2013
Appl. No.:
13/760874
Inventors:
Tracy D. Maahs - Yorba Linda CA,
John A. Cox - San Clemente CA,
Christopher James Earley - San Clemente CA,
Assignee:
USGI Medical, Inc. - San Clemente CA
International Classification:
A61B 17/12
US Classification:
600 37
Abstract:
A surgical method for treating obesity by reducing the size and/or function of the stomach includes forming at least two plications or tissue folds in tissue of a patient using anchor assemblies having a loop. The plications are then optionally allowed to heal. A loop suture or wire is threaded through the loops. The loop suture is then tensioned to draw the plications towards each other. The loop suture is then secured via a knot or a cinch. When the method is performed in the stomach for treatment of obesity, forming the plications reduces the volume of the stomach. Drawing the plications together creates a contracted tissue area which further reduces the volume of the stomach. Additional plications may also be formed and drawn together with the same loop suture, or with a different loop suture.

Compressible Tissue Anchor Assemblies

US Patent:
2013013, May 30, 2013
Filed:
Jan 23, 2013
Appl. No.:
13/748302
Inventors:
Tracy D. Maahs - Yorba Linda CA,
Marvin C. Elmer - Rancho Santa Margarita CA,
Richard C. Ewers - Fullerton CA,
Assignee:
USGI Medical, Inc. - San Clemente CA
International Classification:
A61B 17/04
US Classification:
606232
Abstract:
Apparatus and methods optimize anchoring force in securing tissue folds. Over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchors having expandable designs configured to minimize contact area between the anchor and tissue. When the anchor is in its expanded configuration, a load is applied to the anchor until it is optimally configured to accommodate a range of deflections while the anchor itself exerts a substantially constant force against the tissue.

Methods And Apparatus For Off-Axis Visualization

US Patent:
2013004, Feb 14, 2013
Filed:
Aug 28, 2012

Endoluminal Surgical Tool With Small Bend Radius Steering Section

US Patent:
2012023, Sep 20, 2012
Filed:
May 30, 2012
Appl. No.:
13/483371
Inventors:
Sean Mitchell - Oceanside CA,
Richard C. Ewers - Fullerton CA,
Tracy D. Maahs - Yorba Linda CA,
Assignee:
USGI MEDICAL, INC. - San Clemente CA
International Classification:
A61M 25/092
US Classification:
604 9504
Abstract:
An endoluminal surgical instrument has first and second steering controls on a handle. A flexible shaft attached to the handle has a distal steerable end including a first link and a second link separated by a plurality of intermediate links. First and second steering elements, such as pairs of steering wires, are linked to first and second steering controls and to the first and, second links. One or more of the links is pivotable through an angle of at least 30 degrees relative to an adjoining link. The set back position of the second steering elements from the first steering elements, and the pivoting capability of the links allows the steerable end to be steered into a small bend radius. This makes the instrument highly maneuverable for use in endoluminal surgery, such as incision-less surgery of the stomach.
