Claim 7:
8. A medical system comprising:
a sheath configured to be inserted into a vessel of a living subject;
a catheter configured to be inserted into the sheath and comprising a distal end assembly; and
a catheter introducer apparatus configured to compress the distal end assembly of the catheter for insertion into the sheath, and comprising:
a compression conduit having a truncated conical-form cavity, and including a distal opening and a proximal opening, the proximal opening being configured to receive the distal end assembly of the catheter therein, the cavity tapering from the proximal opening to the distal opening so that successive respective portions of the distal end assembly are compressed as the catheter is advanced distally in the cavity;
a distal connector connected to the distal opening of the compression conduit, and configured to be reversibly coupled to the sheath and to provide passage for the compressed portions of the distal end assembly from the compression conduit into the sheath; and
a proximal retainer disposed adjacent to the proximal opening and including two opposing surfaces defining a gap through which at least part of the distal end assembly is inserted, the opposing surfaces being configured to at least partially prevent compression of portions of the distal end assembly while more distally disposed portions of the distal end assembly are being compressed in the compression conduit, the opposing surfaces of the proximal retainer including a first curved opposing surface and a second curved opposing surface, and the proximal retainer including a curved open loop comprising a curved element including the second curved opposing surface.
