Patent ID: 11291565

Abstract:
Asymmetric external support for stabilizing vein grafts used in coronary arterial bypass graft (CABG) procedures, and applications thereof. Includes: tubular wire braided mesh longitudinally extending proximally and distally, configured with non-paired elastic wires and paired plastically deformable wires. Elastic wires extend along support full length. Paired plastically deformable wires proximal ends are non-connected and open. Plastically deformable wires extend less than support full length, and are configured with inter-looped distal end portions (loops) proximally longitudinally offset from support distal end, and outwardly radially extending beyond support outer radius. Loops may be individually secured, via loop closure securing procedures. In CABG procedures, support externally covers vein grafts, whereby support distal portion (with longitudinally offset loops) is positionable at coronary artery anastomosis sites, and support proximal end is positionable at other anastomosis sites. Eliminates, or minimizes, plastically deformable wires from injuring heart or/and vascular tissue in vicinity of coronary artery anastomosis sites.
