Patent number: 6387977Abstract: An impoved barrier or drug delivery system which is highly adherent to the surface to which it is applied is disclosed, along with methods for making the barrier. In the preferred embodiment, tissue is stained with a photoinitiator, then the polymer solution or gel having added thereto a defined amount of the same or a different photoinitiator is applied to the tissue. On exposure to light, the resulting system polymerizes at the surface, giving excellent adherence, and also forms a gel in the rest of the applied volume. Thus a gel barrier of arbitrary thickness can be applied to a surface while maintaining high adherence at the interface. This process is referred to herein as “priming”. The polymerizable barrier materials are highly useful for sealing tissue surfaces and junctions against leaks of fluids. In another embodiment, “priming” can be used to reliably adhere preformed barriers to tissue or other surfaces, or to adhere tissue surfaces to each other.Type: GrantFiled: July 14, 2000Date of Patent: May 14, 2002Assignees: Focal, Inc., Board of Regents, The University of Texas SystemInventors: Amarpreet S.

Patent number: 6106556Abstract: A rigid or semi-rigid reinforcement member is inserted into or over the damaged portion of an injured tendon or ligament. The tendon or ligament is connected to the reinforcement member such that the cord-member combination can immediately withstand normal tensile forces. The interconnection can be mechanical, such as by pins extending through the sleeve reinforcement member and cord. The sleeve can be bioabsorbable over a sufficiently long period of time that the cord is healed by the time the sleeve is absorbed.Type: GrantFiled: October 29, 1998Date of Patent: August 22, 2000Assignee: Omeros Medical Systems, Inc.Inventors: Gregory A. Demopulos, Stephen A. Yencho, David A. Herrin, Neil G. McIlvaine, Michael D. Nelson, Milton R. Sigelmann, Jose T.V. de Castro, George Selecman, John Collins, Imrann Aziz, Gorm Bressner, Nicholas R. Kalayjian, Charles S. McCall, Robert W. Mericle

Patent number: 6080192Abstract: The damaged portion of an injured tendon or ligament (C) ("connective cord") is inserted into a thin, hollow sleeve (100, 110, 120, 130, 140, 160, 180, 200, 240, 260, 270, 300, 390, generically designated "S") and is connected to the sleeve (S) such that the cord-sleeve combination can immediately withstand normal tensile forces. The interconnection can be mechanical, such as by pins (22, 22',148, 150, 164, 188, 190, 206, 206', 210, 226, 230, 238, 239, 266, 286, 308) extending through the sleeve (S) and cord (C). The sleeve (S) can be bioabsorbable over a sufficiently long period of time that the cord (C) is healed by the time the sleeve (S) is absorbed.Type: GrantFiled: May 28, 1998Date of Patent: June 27, 2000Assignee: Omeros Medical Systems, Inc.Inventors: Gregory A. Demopulos, Stephen A. Yencho, David A. Herrin, Neil G. McIlvaine, Michael D. Nelson, Milton R. Sigelmann, Jose T. V. de Castro, George Selecman, John Collins, Imraan Aziz, Gorm Bressner

Patent number: 5314417Abstract: A safety trocar is provided which includes a spring-loaded shield that shields the cutting tip of the obturator after the obturator penetrates tissue. The distal end of the shield is conical in profile and contains a slot which conforms to the geometry of the cutting tip. The obturator tip contains a knife edge blade which extends the length of the cannula inner diameter. Ideally, the knife is made of an amorphous metal, and may be serrated at its edge.Type: GrantFiled: December 22, 1992Date of Patent: May 24, 1994Assignee: Ethicon, Inc.Inventors: Randy R. Stephens, Gregory D. Bishop, James Voegele, Diane Welling, Richard Smith, John M. Collins, George Selecman
