Patent number: 8795355Abstract: Apparatus for delivering a prosthetic heart valve into a patient by means that are less invasive than conventional open-chest, open-heart surgery. The prosthetic valve may be collapsed while in a delivery device. When the valve reaches the desired implant site in the patient, the valve can be released from the delivery device, which allows the valve to re-expand to the configuration in which it can function as a heart valve. For example, the delivery device may be constructed to facilitate delivery of the prosthetic valve into the patient via the apex of the patient's heart.Type: GrantFiled: July 30, 2013Date of Patent: August 5, 2014Assignee: St. Jude Medical, Inc.Inventor: Yousef F.

Patent number: 8790358Abstract: Methods and apparatus for making an anastomotic connection between an opening at an end of a graft conduit and an aperture in a side wall of a body tissue conduit using a hollow connector assembly are provided, wherein the cross-sectional area of the anastomotic connection is larger than that of the graft conduit. The tissue about the opening is introduced about and retained by first members of a distal portion of the connector assembly held by a loading tool. A delivery tool then collapses a proximal portion defined by second members of the connector assembly and delivers the second members into the lumen of the body tissue conduit via the aperture. Upon inserting the second members into the body tissue conduit, the delivery tool is disemployed and the second members expand such that they press against the interior wall of the body tissue conduit and such that the first members are held within the aperture against a medial wall of the body tissue conduit.Type: GrantFiled: March 29, 2004Date of Patent: July 29, 2014Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Matthew Baker, Michael P.

-
Patent number: 8672968Abstract: A suture construction and method for forming a suture construction is disclosed. The construction utilizes a suture having an enlarged central body portion defining a longitudinal passage. First and second ends of the suture are passed through first and second apertures associated with the longitudinal passage to form a pair of loops. Portions of the suture lay parallel to each other within the suture. Application of tension onto the suture construction causes constriction of the longitudinal passage, thus preventing relative motions of the captured portions of the suture.Type: GrantFiled: February 8, 2010Date of Patent: March 18, 2014Assignee: Biomet Sports Medicine, LLCInventors: Kevin T.

Patent number: 8663256Abstract: A method of laparoscopically repairing a hernia defect comprises inserting into the patient's abdomen a surgical mesh sheet larger than the hernia defect and having a fixation fin with its proximal edge attached to a surface of the sheet. The mesh sheet is manipulated into position with the sheet surface in place at the peritoneal surface of the patient's abdominal wall and the fixation fin disposed in the hernia defect. The method reapproximates opposing edges of the defect by suturing them together with the fixation fin between them, after which the distal edge of the fixation fin is below the external surface of the patient's abdomen. The sheet is then laparoscopically positioned and anchored to the abdominal wall peritoneal surface.Type: GrantFiled: August 23, 2012Date of Patent: March 4, 2014Inventor: George C. Christoudias
