Abstract
Abstract A coring device (10) for coring body tissue to define reproducible patent channels in the body tissue is provided. The coring device utilizes a coring member (20) that is rotatable and linearly advanceable at coordinated predetermined rates to core body tissue. The device can include a suction assembly (106) 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).

Independent Claim
60 words
A coring device comprising: a housing defining a longitudinal axis; a coring member mounted in said housing; an advancing assembly mounted for engagement with said coring member to effect longitudinal motion thereof; and a drive assembly connected to said advancing assembly for activating said advancing assembly to move the coring member longitudinally at a predetermined rate to core body tissue.
Claim 2
Dependent Claim
47 words
A coring device according to claim 1, further comprising a rotation assembly mounted for engagement with said coring member, said drive assembly connected to said rotation assembly for activating said rotation assembly to rotate the coring member in coordination with the longitudinal advancement of the coring member.
Claim 3
Dependent Claim
30 words
A coring device according to claim 1 or 2, further comprising an oscillation assembly mounted for engagement with said coring member, said oscillation assembly effecting oscillation of the coring member.
Claim 4
Dependent Claim
