Methods For Performing Gastroplasty

US Patent:
7520884, Apr 21, 2009
Filed:
May 7, 2004
Appl. No.:
10/841233
Inventors:
Lee L. Swanstrom - Portland OR, US
Richard C. Ewers - Fullerton CA, US
Tracy D. Maahs - Rancho Santa Margarita CA, US
Eugene G. Chen - Carlsbad CA, US
Vahid Saadat - Atherton CA, US
Assignee:
USGI Medical Inc. - San Clemente CA
International Classification:
A61B 17/08
US Classification:
606153
Abstract:
Methods for performing gastroplasty include reducing the effective volume or cross-sectional area of the stomach via approximation of gastric tissue. Such reduction preferably is achieved endoluminally, either with or without laparoscopic ports. In one variation, a sleeve, pouch, Magenstrasse and Mill, Vertical Banded Gastroplasty (“VBG”), etc. ,is formed within the stomach by approximating opposing anterior and posterior segments or ridges of the stomach wall at locations inferior to the gastroesophageal junction. In another variation, opposing walls of the stomach are approximated at a plurality of substantially random locations to reduce an effective volume of the stomach. In yet another variation, both a sleeve and random approximations are formed, the random approximations preferably disposed in a portion of the stomach excluded by the sleeve. In still another variation, opposing walls of the stomach are approximated over significant lengths at random or specified locations.

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, US
Tracy D. Maahs - Rancho Santa Margarita CA, US
Cang C. Lam - Irvine CA, US
Vahid Saadat - Saratoga CA, US
Chris Rothe - San Jose CA, US
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.

Compressible Tissue Anchor Assemblies

US Patent:
7678135, Mar 16, 2010
Filed:
Apr 14, 2006
Appl. No.:
11/404423
Inventors:
Tracy D. Maahs - Rancho Santa Margarita CA, US
Marvin C. Elmer - Rancho Santa Margarita CA, US
Richard C. Ewers - Fullerton CA, US
Assignee:
USGI Medical, Inc. - San Clemente CA
International Classification:
A61J 17/00
US Classification:
606232, 606198, 606216
Abstract:
Apparatus & methods for optimizing anchoring force are described herein. In securing tissue folds, over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchors having expandable arms 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. Various devices, e. g. , stops, spring members, fuses, strain gauges, etc. , can be used to indicate when the anchor has been deflected to a predetermined level within the optimal range. Moreover, other factors to affect the anchor characteristics include, e. g. , varying the number of arms or struts of the anchor, positioning of the arms, configuration of the arms, the length of the collars, etc.

Apparatus And Methods For Positioning And Securing Anchors

US Patent:
7736378, Jun 15, 2010
Filed:
May 7, 2004
Appl. No.:
10/841245
Inventors:
Tracy D. Maahs - Rancho Santa Margarita CA, US
Richard C. Ewers - Fullerton CA, US
Jesus Flores - Perris CA, US
Alexander Khairkhahan - Palo Alto CA, US
Vahid Saadat - Atherton CA, US
Cang C. Lam - Irvine CA, US
Assignee:
USGI Medical, Inc. - San Clemente CA
International Classification:
A61B 17/04
US Classification:
606232
Abstract:
Apparatus and methods for positioning and securing anchors are disclosed herein. The anchors are adapted to be delivered and implanted into or upon tissue, particularly tissue within the gastrointestinal system of a patient. The anchor is adapted to slide uni-directionally over suture such that a tissue plication may be cinched between anchors. A locking mechanism either within the anchor itself of positioned proximally of the anchor may allow for the uni-directional translation while enabling the anchor to be locked onto the suture if the anchor is pulled, pushed, or otherwise urged in the opposite direction along the suture. This uni-directional anchor locking mechanism facilitates the cinching of the tissue plication between the anchors and it may be utilized in one or several anchors in cinching a tissue fold.
