A device for forming openings (holes) in internal bodily tissue is provided. The device includes a cutter defining a longitudinal passageway and a cutting edge. The device also includes an inner core in reciprocally sliding relationship with the cutter having a tissue engagement portion at its distal end. A syringe-like mechanism moves the cutter and the core substantially co-axially between a first position wherein the distal portion of the core extends distally of the cutting edge and a second position wherein the distal portion of the core resides within the passageway. Tissue is sheared as the core and cutter are moved from the first to the second position. The core and cutter are attached to different portions of the syringe-like mechanism such that the longitudinal axes of the cutter passageway, the core member and the activation assembly may deviate (i.e., &ldquo;float&rdquo;) relative to one another.
