Patent number: 8679138Abstract: The invention relates to an apparatus and method for forming a hole in a wall of a hollow organ. The applicator includes a hole forming element for forming a hole in the wall of the organ, a positioning means for positioning the hole forming element, and a retractor element. In addition, the applicator includes a sequencing means for coordinating the relative movement of the retractor element and the hole forming element in a sequential manner to thereby carry out a procedure for forming a hole in the wall of the hollow organ. The sequencing means may further include a safety latch element operatively coupled to the retracting means and the hole forming element. The safety latch of the invention keeps prevents damage to the internal surface of the organ during the formation of the hole.Type: GrantFiled: September 21, 2010Date of Patent: March 25, 2014Assignee: Correx, Inc.Inventors: Richard M. Beane, John W. Brown, James Alan Crunkleton, James S. Gammie, Joseph L. Smith, Jr.

Patent number: 8679137Abstract: A buttress for use with circular surgical staplers that does not require adhesive to securely fasten the buttress to the stapler. Following cutting and stapling by the circular stapler, the buttress has an adaptive opening through its central region with a diameter smaller than the outer diameter of the stapler anvil. Because of relief features built into the buttress, the stapler anvil may be pulled through the buttress material without causing permanent alteration to the buttress. These relief features may be provided regardless of whether the buttress is made of inelastic or elastic materials. The buttress is generally circular in shape with an outer diameter sized to coincide with the outer diameter of the stapler body staple compression surface and the outer diameter of the anvil compression surface of a circular stapler with which it is used. Prior to surgical use, the buttress is attached to the stapler with disruptable portions extending from outer perimetal areas of the buttress.Type: GrantFiled: October 2, 2008Date of Patent: March 25, 2014Assignee: W. L. Gore & Associates, Inc.Inventors: Ann M. Bauman, Stuart E. Broyles, Jerald M. Crawley, John R. Daugherty, Norman Pih

Patent number: 8672957Abstract: Apparatus is provided for applying one or more patches to a tubular structure in a body of a patient. The apparatus includes an applicator, which is configured to removably hold the one or more patches, and to place the one or more patches at least partially around the tubular structure. The applicator includes one or more patch supports. Each of the patch supports includes a yielding pad, which is removably coupleable to one of the patches; and a stiff back support structure, to which the yielding pad is fixed. Each of the patch supports is shaped so as to define at least one chamber that itself has a volume of at least 0.5 ml when the patch supports are in respective resting states. Other embodiments are also described.Type: GrantFiled: July 28, 2011Date of Patent: March 18, 2014Assignee: SEAlantis Ltd.Inventors: Ohad Kimhi, Dudu Haimovich, Aviad Louzon

Patent number: 8672958Abstract: Methods and devices for treating obesity are provided, and more particularly, methods and devices for performing gastric bypasses are disclosed. In one exemplary embodiment a gastric bypass procedure is provided that includes forming a gastro-entero anastomosis between a stomach and an intestine and forming an entero-entero anastomosis between a portion of the intestine distal to the gastro-entero anastomosis and a portion of the intestine proximal to the gastro-entero anastomosis. A surrogate path is formed between the esophagus and the gastro-entero anastomosis to at least partially direct fluid from the esophagus to the intestine by way of the gastro-entero anastomosis, thereby bypassing the stomach. Still further, methods for repairing an abdominal aortic aneurysm and leaking heart valve are also disclosed.Type: GrantFiled: June 7, 2012Date of Patent: March 18, 2014Inventors: James E. Coleman, Christy Cummins

Publication number: 20140074130Abstract: A method of performing a surgical anastomosis is disclosed. The method includes providing an anastomotic device including a fluid supply channel extending between a handle assembly and a head assembly. The method also includes positioning the head assembly of the anastomotic device adjacent a hollow tissue organ, inserting the head assembly of the anastomotic device into the hollow tissue organ, and discharging an inflation fluid through at least one fluid outlet and into the hollow tissue organ to insufflate at least a portion of the hollow tissue organ.Type: ApplicationFiled: August 27, 2013Publication date: March 13, 2014Applicant: Covidien LPInventor: Boris Vestweber
