An apparatus for harvesting a subcutaneous blood vessel is disclosed. The apparatus comprises a guidewire with an angled tip, an intra-vascular catheter to receive the guidewire and having a lateral orifice to allow the angled tip thereof to perforate the subcutaneous blood vessel. The apparatus further comprises a flexible pulling device having a pair of circumferential grooves, one adjacent to each end thereof, to allow for securing the subcutaneous blood vessel thereat; and a flexible pushing device having a concave-cup shape at a distal end thereof to facilitate pushing of the subcutaneous blood vessel secured with one of the pair of circumferential grooves of the flexible pulling device. The flexible pulling device and the flexible pushing device are operable in conjunction to cause inversion and eversion and separation from the surrounding tissues of the subcutaneous blood vessel for removal and harvesting thereof.
