A self-retaining retractor which can be assembled and used without assistance, retracting a surgical incision, retaining the incision open, and providing for retraction of internal organs and tissues inside the patient's body through the open incision. Flexible, resilient incision retractor paddles are placed into the incision, a rigid frame consisting of two interlocking halves is laid longitudinally over the incision. The incision retractor paddles in the incision are manually clipped to each frame half then the frame halves are opened to the desired extent. Incision retractor paddles and frame provide the apparatus stability for retraction of internal organs and tissues through the open incision by the addition of mounting jigs containing attachment posts onto mounting means which radiate outward from the frame. Internal organ and tissue retraction means are affixed to the attachment posts.

A valve cutter for arterial bypass surgery is provided and includes a blade assembly for cutting the venous valves, a shaft for guiding the blade assembly through the bypass vein, an expansion means for preventing the blade assembly from contacting the walls of the bypass vein and for helping to propagate the incisions made in the valve leaflets by the blade assembly, and a control means for controlling the expansion and contraction of the expansion means in order to allow for use of the invention in a variety of bypass vein diameter sizes.

An improved insertion instrument for a vena cava filter is provided and iudes a filter retainer attached to the catheter for preventing accidental ejection of the filter and for enabling retraction of the filter into the carrier body at any time prior to complete ejection; a directional control mechanism attached to the plunger housing for allowing a user to guide the filter retainer through a vascular network; and a simplified plunger locking mechanism on the plunger for preventing premature ejection of the filter.
