    摘要： A specimen-receiving receptacle apparatus for use in minimally invasive surgical procedures can be remotely opened and closed from a proximal end of the apparatus, outside of the patient. The apparatus includes a belt having substantial longitudinal rigidity so that the belt can be forced longitudinally into the surgical site to open the specimen-retrieval receptacle from a remote end of the apparatus. The belt can be longitudinally pulled out of the surgical site to close the specimen-retrieval receptacle from outside of the patient. The belt is relatively flexible or easily deformable along an open end of the receptacle without deforming substantially out of the plane of the open receptacle end. This is achieved by aligning the belt with respect to the open end such that a large dimension of the belt is aligned transverse to the plane of the open receptacle end. In a preferred embodiment, the belt is extruded from nylon and has an elliptical cross-sectional shape.

    摘要： An improved valve cutter for in-situ incision of valve leaflets which safely, efficiently, and consistently renders venous valves incompetent while minimizing frictional forces on the endothelium of the vessel and preventing inadvertent contact between cutting surfaces and the intima of the vein wall. The valve cutter includes a plurality of proximally directed prongs presenting sharp edges, where the prongs are separated by slots similarly presenting sharp edges to pierce the valve leaflets so that the cutting head is provided with a continuous cutting surface in multiple planes running along the entire forward edge of the cutting head.
