The plugs are also adapted to be removed from the fallopian tubes in a relatively simple procedure without adversely affecting the fallopian tubes.Type: ApplicationFiled: October 23, 2003Publication date: September 2, 2004Inventor: Sundaram Ravikumar

Patent number: 6780195Abstract: An instrument for clamping and cutting a deformable flexible tube includes handles and jaws pivotally coupled together on opposite sides of a pivot member, a fixed cutting blade on the jaws, integrally hinged lockable V-clamps with ratcheted inner gripping surfaces mounted in the jaws with the edge of the cutting blade positioned above the ratcheted surfaces of the V-clamps, and a device to push the V-clamp axially forward in the jaws. When the handles are pressed together to an intermediate position, the jaws are closed only partially locking the arms of the V-clamps while leaving the edge of the cutting blade distanced from the center of the clamp and from the tube, and when the handles are pressed further to a cutting position, the locked V-clamp is pushed forward in the jaws simultaneously closing the jaws completely and bringing down the cutting blade.Type: GrantFiled: May 9, 2002Date of Patent: August 24, 2004Assignee: Starburst Technologies LimitedInventor: Michael Porat

Patent number: 6776783Abstract: An improved surgical clip and clip applicator for placing a surgical clip over a target structure. The surgical clip generally has a pair of opposing clamp arms, each having an associated clamping surface, and a connecting portion joining the clamp arms and biasing them to a normally closed position. The surgical clip may be opened and locked into the open position prior to being loaded into a clip applicator or the surgical clip may be opened by a clip applicator itself. The surgical clip and clip applicators require reduced actuation forces and simplified applicator mechanisms.Type: GrantFiled: December 21, 2000Date of Patent: August 17, 2004Assignee: CardioThoracic Systems, Inc.Inventors: John J. Frantzen, Charles S. Taylor, Michael V. Morejohn, Dwight P. Morejohn, Ronald Devore

Patent number: 6776789Abstract: This invention is a cinch suture having first and second segments and a locking device joining these segments which responds to teeth on the first segment to lock a ligature in place and prevent loosening. The locking device has teeth positioned to interact with engaging elements carried by the first segment as it is passed through the locking device to prevent removal. The locking device teeth are flexible and movable and arranged in two rows in a face to face offset relationship. The first segment engaging elements have a spherical configuration. The first segment passing through the locking device forms an endless loop for encircling and closing an opening formed by surgical excision of an organ or vessel. The locking mechanism has a receiving entrance and a removal exit. The two rows of offset teeth alternately engage spherical engaging elements to provide minute adjustment in the tightness of the suture and place pressure on the suture to hold it firmly in place.Type: GrantFiled: April 16, 2001Date of Patent: August 17, 2004Inventors: Todd Bryant, G. Leon Robbins, III

Patent number: 6773440Abstract: Methods and devices for use in tissue approximation and fixation are described herein. The present invention provides, in part, methods and devices for acquiring tissue folds from the anterior and posterior portions of a hollow body organ, e.g., a stomach, positioning the tissue folds for affixing within a fixation zone of the stomach, preferably to create a pouch or partition below the esophagus, and fastening the tissue folds such that a tissue bridge forms excluding the pouch from the greater stomach cavity. The present invention further provides devices for performing a transoral, endoscopic hollow organ division, including a tissue acquisition device capable of acquiring the desired tissue, a tensioning device for positioning the acquired tissue, and a fastening element to secure the outer layers of the acquired tissue such that the desired healing response is achieved.Type: GrantFiled: July 2, 2002Date of Patent: August 10, 2004Assignee: Satiety, Inc.Inventors: Jamy Gannoe, Gary Weller, Craig Gerbi, Douglas S. Sutton, Gilbert Mata, Jr., J. Stephen Scott

Publication number: 20040153105Abstract: The invention is directed to a uterine artery clamp and the relatively non-invasive treatment procedure utilizing this clamp. The uterine clamp includes a clamping member having a jaw with tissue-contacting surfaces for applying pressure to target tissue and a stabilizing member which is configured to be inserted into the patient's uterine cervical canal. The clamp may be provided with elongated handles to manually adjust the spacing between the jaw and stabilizer and thereby apply pressure to a uterine artery beneath a bundle of tissue held between the jaw and stabilizer. Uterine clamps embodying features of the invention by be used in procedures for treating uterine disorders such as fibroids, DUB, PPH and the like.Type: ApplicationFiled: May 6, 2003Publication date: August 5, 2004Applicant: Vascular Control Systems, Inc.Inventors: Fred H. Burbank, Michael L. Jones, Greig E. Altieri

Publication number: 20040153106Abstract: A gastric band of a belt type is presented for attaching around a circumference of a patient's stomach, so as to define the diameter of the stomach opening. The band comprises outer and inner surfaces, wherein the inner surface engages the stomach, and at least the outer surface is formed by an elongated member substantially non-extendable along a longitudinal axis thereof. A through-going opening is made in the elongated member and is located so as to define an end portion of the band having a predetermined length. An opposite end portion of the band is shaped so as to be insertable into the through-going opening for adjusting a desired inner diameter of the band in its closed operating position and fastening the opposite end portion to the outer surface of the band.Type: ApplicationFiled: January 13, 2004Publication date: August 5, 2004Inventor: Moshe Dudai

Publication number: 20040143276Abstract: Inserts configured for attachment to a jaw of a jaw-type occlusion device, such as a surgical clamp or clip, and surgical clamps or clips having such jaw inserts. The inserts include a compliant cushion having a clamping surface adapted for engagement with a vessel or other body tissue, the clamping surface having a plurality of integrally-formed raised patterns extending from the surface to at most 0.010 inches. The raised patterns can be repeating and uniform in nature, or random and non-uniform in nature.Type: ApplicationFiled: January 22, 2003Publication date: July 22, 2004Inventors: Karrie L. Sturtz, David J. Danitz, June Carnegie, Thomas L. Baughman
