Instruments and methods for minimally invasive vascular procedures

摘要: A 360° dissection instrument and method for accomplishing an atraumatic blunt of connective tissues in around the circumference a saphenous vein branch veins to facilitate minimally invasive harvesting vein. The pulsable dissector has elongate body with distal dissecting surface that is progressively "circumferential" or "wrapped" axial vessel-receiving passageway channel. includes longitudinal gap reduced transverse dimension proximal direction funnel through gap. wrapped "active" periphery incorporating expansion structure elastomeric material having interior pressurizable chamber. An inflation lumen communicates pressure source pulse-control mechanism. single pulse will move "pulse cycle" "expansion phase" "contraction" phase at intervals ranging from 1/second 100/second. In one embodiment, endoscopic viewing means are provided within dissector.
