ABSTRACT:
Novel surgical tools and methods for off-pump surgery are described herein. A novel coring system is disclosed which employs a balloon catheter and a coring tool which is adapted to be threaded on to a guide wire. The guide wire serves as a track upon which the coring tool is guided. Embodiments of the coring tool ensure complete removal and excision of cored tissue. In addition, the described coring system prevents blood loss during off-pump surgery. In an embodiment, a surgical coring tool comprises a hollow body having an open distal end and a closed proximal end. The open distal end has a cutting edge. The hollow body comprises a vacuum connection to apply suction from said hollow body. The surgical coring tool also comprises a hollow elongate member disposed coaxially within said hollow body. The elongate member is adapted to be inserted on to a guide wire.
