Abstract:
1. A suture retriever-sheath dilator tool for use in surgery on a tendon of a patient comprising: a distal end, a proximal end opposite the distal end, and a length between the distal and proximal ends; a shaft having a distal end, a proximal end opposite the distal end, and a length between the distal and proximal ends of the shaft, the shaft being configured to pass at least in part through a tendon sheath, the shaft having a first cross section transverse to the length of the shaft having a convex upper exterior surface configured to contact an inner surface of the tendon sheath, the first cross section of the shaft having a concave lower exterior surface opposite the convex upper exterior surface configured to contact an outer surface of the tendon, the shaft having a thickness perpendicular to the length of the shaft and between the convex upper and concave lower exterior surfaces, the shaft having a width perpendicular to the thickness and the length of the shaft, the shaft increasing in thickness from said distal end of the shaft to said proximal end of the shaft over at least a portion of the length of the shaft; a tip extending from the distal end of the shaft for insertion into and through the tendon sheath, the tip being configured to permit a suture in the tendon to be attached to the tip; and a handle extending from the proximal end of the shaft.
