Patent number: 7241302Abstract: An aortic punch for creating an aortotomy in a wall of a luminal structure. The aortic punch includes a housing having distal and proximal ends, first and second plungers, a first return spring and a cutting assembly. The first plunger is movable relative to the housing to expose a barb from the distal end of the housing for piercing and catching the wall of the luminal structure. The first return spring biases the barb proximally toward the distal end of the housing such that the barb pulls the wall of the luminal structure into contact with the cutting assembly. The present disclosure also relates to a method of forming an aortotomy in a luminal structure.Type: GrantFiled: October 18, 2001Date of Patent: July 10, 2007Assignee: Tyco Healthcare Group LPInventors: Kevin Sniffen, Scott E.

Patent number: 6488636Abstract: An apparatus and method for the biopsy of tissue specimens and, more particularly, a single insertion multiple sample percutaneous biopsy apparatus and method are provided. A tip at a distal end of a vacuum support tube is introduced into a tissue mass. The vacuum support tube is retracted exposing a basket tube bounded by a front washer and a rear washer mounted thereabout forming a tissue basket. The basket tube is supported internally by a thrust tube which provides structure to the apparatus to allow it to penetrate tissue. The thrust tube and the basket tube are in fluid connection and are provided with suction to draw tissue inward. The tissue is then severed by rotating and advancing a knife edge at the distal end of the vacuum support tube. The tissue basket is withdrawn and the tissue sample is removed by rotating the vacuum support tube. The tissue sample is sliced longitudinally, and a stripper scrapes the tissue sample from an opening in the vacuum support tube.Type: GrantFiled: June 7, 2001Date of Patent: December 3, 2002Assignee: United States Surgical CorporationInventors: Graham W.

Patent number: 6224608Abstract: A tissue gripping thread configuration for securely positioning an elongated medical instrument relative to body tissue. The tissue gripping thread includes curved distal and proximal foot sections connected to a thread base, a curved distal thread surface extending from the distal foot section to a thread apex, and a proximal thread wall substantially perpendicular to the base surface extending from the proximal curved foot section to the thread apex. In the preferred embodiment the flank angle of the distal thread surface is substantially greater than the flank angle of the proximal thread wall. The preferred thread configuration reduces trauma to tissue during insertion and removal of an associated medical instrument while ensuring secure positioning of the instrument relative to tissue. Preferred thread dimensions and radii, as well as embodiments for associating the preferred thread configuration with a trocar device are disclosed.Type: GrantFiled: June 3, 1993Date of Patent: May 1, 2001Assignee: United States Surgical CorporationInventors: Michael Ciccolella, Paul A.

Patent number: 6007495Abstract: A biopsy apparatus for obtaining tissue samples includes a housing, an elongated member slidably and rotatably mounted in the housing and a blade having a stem portion pivotally mounted on the elongated member and moving transversely relative to a longitudinal axis of the elongated member between a stowed position and a deployed position. A method of sampling tissue includes the steps of providing the biopsy apparatus, inserting the elongated member into a tissue mass, deploying the blade, severing a tissue sample from the tissue mass by proximally retracting and rotating the elongated member, removing the elongated member from the tissue mass and extracting the tissue sample from a patient.Type: GrantFiled: January 22, 1998Date of Patent: December 28, 1999Assignee: United States Surgical CorporationInventor: Paul A.
