Patent ID: 8540646

Claim:
A biopsy punch device comprising: (a) a housing comprising a proximal end and a distal end, (b) a biopsy punch cutter assembly surrounded by the housing, wherein said cutter assembly includes an elongated hollow cutter shaft comprising: (i) a cutter shaft distal end, and, (ii) a cutter comprising an articulated section, wherein said cutter extends distally from said distal end of said housing, wherein said cutter is coupled to the cutter shaft distal end and wherein said cutter shaft is configured to provide linear and rotational displacements of the cutter with respect to the distal end of said housing; (c) a bearing shaft located within said housing, wherein said bearing shaft surrounds the biopsy punch cutter assembly, wherein said cutter extends distally from a distal end of said bearing shaft, wherein said articulated section comprises a diameter that is larger than an inner diameter of said bearing shaft, and wherein said bearing shaft and articulated section are configured such that the bearing shaft flattens said articulated section and thereby reduce said diameter of said articulated section during said linear displacement of said cutter; (d) a suture-less fastener member for closing a wound in tissue, wherein said suture-less fastener member surrounds said biopsy punch cutter assembly; (e) a suture-less fastener member dispenser assembly for dispensing the suture-less fastener member, wherein said dispenser assembly comprises a loading mechanism and a trigger; and (f) an actuator assembly comprising an actuator mechanism for providing a linear and rotational displacement to the cutter shaft.
