Abstract
A coring device for coring body tissue to define reproducible patent channels in the body tissue is provided. The coring device utilizes a coring member that is rotatable and linearly advanceable at coordinated predetermined rates to core body tissue. The device can include a suction assembly suitable for use during biopsy procedures and a cautery assembly to cauterize the cored body tissue. The coring member can also be oscillated along its longitudinal axis to effect cauterization and/or coring. The coring device is particularly suited for Transmyocardial Revascularization (TMR).
