Patent number: 5843165Abstract: A method of restoring lost blood flow capacity to an artery is disclosed. The artery is enlarged by enlarging the flow path of a plaque-ridden segment of the artery using a plaque-removing instrument. The instrument is introduced through a small arteriotomy located remote from the segment. Next, a vascular lining is inserted through the small arteriotomy to a position co-extensive with the segment where the lining is secured.Type: GrantFiled: October 18, 1996Date of Patent: December 1, 1998Assignee: EndoVascular Instruments, Inc.Inventors: Mark Plaia, Vincent A.

Patent number: 5643297Abstract: Disposable intra-arterial augering and dottering instruments for use in patients in clearing pathways at obstructed or nearly obstructed arterial sites are disclosed. A number of augering tips used on the instruments are disclosed along with a method for releasibly affixing augering tips to the instruments. In addition, a dottering tip is disclosed for use in procedures where it is desired to open a pathway without excising material from the obstructed site. A combined augering and dottering tip is disclosed for a procedure in which material displacement followed by excising of material from within an artery is accomplished without removal of the combined augering and dottering tip until the procedure is complete.Type: GrantFiled: March 10, 1995Date of Patent: July 1, 1997Assignee: Endovascular Instruments, Inc.Inventors: Gregory N. Nordgren, Thomas L. Kelly

Patent number: 5282484Abstract: A catheter atherotome and method for its use for performing partial atherectomy in an artery and blood flow through the artery. Several blades are mounted at a distal end of a catheter, in a helical basket configuration and spaced angularly apart from one another about the associated ends of two concentric sheaths in such a way that longitudinal and rotary relative movement of the sheaths selectively bows the blades arcuately outwardly into a cutting position or draws the blades flat into alignment with the sheaths. The blades have sharpened cutting edges extending helically and directed toward the cathether's proximal end when the blades are bowed. Partial removal of an atheroma is effected by manually pulling the basket knife past an atheroma with the basket blades in their outwardly bowed cutting positions, with the speed, force, and amount of expansion of the blades determined by the operator.Type: GrantFiled: July 28, 1992Date of Patent: February 1, 1994Assignee: EndoVascular Instruments, Inc.Inventor: Vincent A.
