Methods For Performing Gastroplasty

US Patent:
7520884, Apr 21, 2009
Filed:
May 7, 2004
Appl. No.:
10/841233
Inventors:
Lee L. Swanstrom - Portland OR,
Richard C. Ewers - Fullerton CA,
Tracy D. Maahs - Rancho Santa Margarita CA,
Eugene G. Chen - Carlsbad CA,
Vahid Saadat - Atherton CA,
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.

Methods For Performing Gastroplasty

US Patent:
2009020, Aug 20, 2009
Filed:
Apr 20, 2009
Appl. No.:
12/426894

Flexible Shaft System Having Interchangeable End Effectors

US Patent:
2006018, Aug 17, 2006
Filed:
Feb 16, 2005
Appl. No.:
11/060231
Inventors:
Tracy Maahs - Rancho Santa Margarita CA,
Richard Ewers - Fullerton CA,
Assignee:
USGI Medical Inc. - San Clemente CA
International Classification:
A61B 18/18
A61B 18/04
US Classification:
606002000, 606027000, 606033000, 606041000
Abstract:
Flexible shaft systems having interchangeable end effectors are described herein. A shaft with a flexibility sufficient to allow advancement through a lumen of an endoscopic device has an interface at its distal end for engaging a removable end effector tool. The shaft and end effector tool are configured to enable endoluminal deployment through a patient, e.g., through the esophagus and into the stomach. The removable end effector tool may comprise any number of different tools, such as graspers, forceps, scissors, snares, needles, etc., each being interchangeable upon the flexible shaft distal end. Once a procedure is done within the patient, the flexible shaft may be withdrawn and another distal end effector tool may be interchanged. The new end effector tool and flexible shaft can then be reintroduced into the patient.

Methods And Apparatus For Maintaining Sterility During Transluminal Procedures

US Patent:
2006025, Nov 16, 2006
Filed:
Apr 7, 2006
Appl. No.:
11/400297
Inventors:
Vahid Saadat - Saratoga CA,
John Cox - Rancho Santa Margarita CA,
Tracy Maahs - Rancho Santa Margarita CA,
Assignee:
USGI Medical, Inc. - San Clemente CA
International Classification:
A61B 1/00
US Classification:
600121000
Abstract:
Methods and apparatus for maintaining sterility during transluminal procedures are described. The sterility is achieved by making use of a membrane in either the form, e.g., of a sheath, cap or umbrella to keep the instruments (endoscopes, overtubes, etc.) sterile while being advanced through lumens in the body and into the various cavities. Methods, such as vacuum acquisition, mechanical tissue anchoring, etc., of the underlying tissue followed by incision of the tissue with, e.g., a needle knife, can be utilized to gain access to the various cavities. It is expected that this procedure will provide the desired level of sterility for transluminal procedures.

Apparatus And Methods For Endoluminal Advancement

US Patent:
2006028, Dec 21, 2006
Filed:
Jun 15, 2005
Appl. No.:
11/154168
Inventors:
Vahid Saadat - Saratoga CA,
Eugene Chen - Carlsbad CA,
Tung Le - Tustin CA,
Tracy Maahs - Rancho Santa Margarita CA,
Richard Ewers - Fullerton CA,
John Cox - Macungie PA,
Chris Rothe - San Jose CA,
Assignee:
USGI Medical Inc. - San Clemente CA
International Classification:
A61M 29/00
US Classification:
606198000
Abstract:
Apparatus and methods for endoluminal advancement are described herein. A shape-lockable tissue anchoring assembly generally has an elongate body, a handle assembly, and an anchoring assembly positioned at or proximal to a distal tip of the elongate body. A distal portion of the elongate body may optionally be steerable or curvable. The anchoring assembly may include various expandable or projecting anchoring features to contact and retain tissue relative to the elongate body such that pleated tissue is temporarily immobile relative to the elongate body. This anchoring can be actuated simultaneously with or independently from shape-locking of elongate body. The anchoring assembly can be actuated simultaneously with the shape-locking of the elongate body. Alternatively, the steerable distal portion of the elongate body can be angled against the pleated tissue to retain it while the endoscope is advanced relative to the pleated tissue.

Methods And Apparatus For Colonic Cleaning

US Patent:
2007001, Jan 18, 2007
Filed:
Jul 12, 2006
Appl. No.:
11/457053
Inventors:
John Cox - Macungie PA,
Tracy Maahs - Rancho Santa Margarita CA,
Assignee:
USGI Medical Inc. - San Clemente CA
International Classification:
A61B 1/00
US Classification:
600114000, 600104000, 600156000, 600116000, 600144000
Abstract:
Apparatus and methods are provided for cleaning a patient's colon in preparation for colonoscopy. A rigidizable overtube is described, as well as several variations of a colon-cleaning element configured for use with the overtube to clean the patient's colon. In one variation, the colon-cleaning element comprises a fluid jet. In another variation, the colon-cleaning element comprises a mechanical brush. Aspiration optionally may be provided for removing blockage material disrupted during colonic cleaning.

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.
