Methods of artificially lining a vessel, especially an artery, of a medical patient to address the existence of a flow-inhibiting atheroma and to significantly alleviate the probability of restenosis, and the resulting products.

Anti-stenotic method and product for occluded and partially occluded

A method of enlarging the lumen of a vessel is disclosed, by which an access opening or passageway is provided to the vessel, a head is inserted through the opening and advanced to a constriction within the vessel. The head engages, severs, and removes plaque. A vascular graft lining is inserted into the vessel and to the site of enlargement where it is secured within the vessel at the site of enlargement.

Method for increasing blood flow in vessels

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.

Method of restoring reduced or absent blood flow capacity

Anti-stenotic method for occluded and partially occluded arteries

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.

Intra-artery obstruction clearing apparatus and methods

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.
