Patent number: 7507246Abstract: A thrombectomy apparatus for breaking up thrombus or other obstructive material in a lumen of a vascular graft or vessel includes a flexible sheath and a wire positioned within the flexible sheath, wherein the wire and flexible sheath are relatively movable. The wire is substantially sinuous in configuration and assumes a substantially sinuous shape when deployed from the flexible sheath and a straighter configuration when retracted into the flexible sheath. The wire is operatively connected to a motor for rotation of the wire to enable the deployed wire to break up the thrombus or other obstructive material.Type: GrantFiled: September 21, 2005Date of Patent: March 24, 2009Assignee: Rex Medical, L.P.Inventors: James F. McGuckin, Peter Hinchliffe, Walter H. Peters

Patent number: 7037316Abstract: A thrombectomy apparatus for breaking up thrombus or other obstructive material in a lumen of a vascular graft or vessel comprising a flexible sheath, and a wire positioned within the flexible sheath wherein the wire and flexible sheath are relatively movable. The wire is substantially sinuous in configuration and assumes a substantially sinuous shape when in the deployed position and assumes a straighter position in the retracted position. The wire is operatively connected to a motor for rotation of the wire to enable peaks of the sinuous wire to contact a wall of the lumen to break up the thrombus or other obstructive material.Type: GrantFiled: April 1, 2002Date of Patent: May 2, 2006Inventors: James F. McGuckin, Jr., Peter W. H. Hinchliffe, Walter H. Peters

Patent number: 6749622Abstract: Clip apparatus for closing a vessel aperture resulting from insertion of a surgical implement comprising an elongated strand comprising a central portion and extremity portions extending from said central portion. The tips of said extremity portions remote from said central portion are shaped to retain tissue encountered thereby. The extremity portions have memory characteristics seeking to cause said extremity portions to curl with respect to said central portions to retain tissue engaged thereby when said strand is in an unconstrained disposition.Type: GrantFiled: October 11, 2002Date of Patent: June 15, 2004Assignee: Rex Medical, L.P.Inventors: James F.

Patent number: 6579299Abstract: A surgical apparatus for removing deposits from an interior of a vessel comprising a rotatable shaft and a rotatable tip mounted to the rotatable shaft which is rotatable about its longitudinal axis upon rotation of the shaft to remove deposits from the interior of the vessel. The tip has a distal portion, a proximal portion and an intermediate portion between the distal and proximal portions. The intermediate portion is defined by a plurality of transverse cross-sectional areas, wherein each transverse cross-sectional area defines first and second axes substantially perpendicular to each other to define a width dimension along a first axis and a height dimension along the second axis. The height dimension is greater than the width dimension.Type: GrantFiled: February 14, 2001Date of Patent: June 17, 2003Assignee: Rex Medical, L.P.Inventors: James F. McGuckin, Jr., Peter W. J.
