Patent number: 6884251Abstract: An anastomosis is performed using a flexible mounting structure mounted on the outside of at least one vessel. Fasteners extend through the vessel and are bent towards the incision to attach the flexible mounting structure to the vessel in a manner that controls the edge of the vessel adjacent to the incision. The mounting structures are oriented on each vessel so fasteners on one mounting structure interdigitate with fasteners on the other mounting structure at the location of contact between the vessels when the two vessels are brought together. This creates two complementary sinusoidal-shaped vessel edges with peaks of one edge being accommodated in the valleys of the other edge. The peak-to-valley orientation forms a sinusoidal-shaped joint which is leak free. The fasteners are spaced so proper pressure is applied to the tissue to promote healing without leaking. Furthermore, the fasteners are sized and shaped to properly engage the tissue and bend in a desired manner.Type: GrantFiled: March 6, 2003Date of Patent: April 26, 2005Assignee: Origin Medsystems, Inc.Inventors: Paul A. Spence, Warren P. Williamson, IV, George Christakis, Mark Ortiz, Craig B. Berky, Douglas P. Allen, Matthew J. Huddleston, Delbert Ted Leimbach, Cecil R. Robinson, E. Dale VanHoose, Thomas J.

Patent number: 6488692Abstract: An access and cannulation device includes a mounting element such as the anastomosis mounting element disclosed in U.S. application Ser. No. 08/714,615 (now U.S. Pat. No. 5,868,763) and U.S. application Ser. No. 09/200,796. The device is used to provide access therethrough and via an incision to the interior of a hollow anatomical structure such as a vessel, an organ or the like during surgery, especially minimally invasive surgery. It includes a flexible sleeve with a suture therein for closing the sleeve and locating edges of the structure adjacent to the incision in position for proper healing after completion of a surgical procedure. A tool is also disclosed for manipulating the device to configure it for the surgery and to close it after completion of the surgery whereby the edges of the wall of the structure adjacent to an incision are approximated to promote proper healing.Type: GrantFiled: March 7, 2000Date of Patent: December 3, 2002Assignee: Origin Medsystems, Inc.Inventors: Paul A. Spence, Warren P. Williamson, IV, George Christakis

Patent number: 5948443Abstract: The present invention pertains generally to the field of Public Health, including the prevention and treatment of coronary heart disease which is currently the first cause of death in the American population. More specifically, the present invention concerns a total modular system of multivitamin and mineral supplementation composed of 7 distinct modules for improving public health by insuring adequate intake of micronutrients needed for disease prevention and protection against nutritional losses and deficiencies due to, for example, lifestyle factors and common inadequate dietary patterns. A module, as used herein throughout, is defined as a separate and distinct combination of vitamin-mineral and other health promoting compounds which are directed to specific target populations. The formulations of the present invention which, when combined in one capsule or tablet or as separate modules, exert a joint and enhancing effect on the major pathogenetic factors involved in the atherosclerotic process.Type: GrantFiled: February 21, 1997Date of Patent: September 7, 1999Assignee: Medical Doctor's Research Institute, Inc.Inventors: Patricia A.
