Abstract
A sheath introducer for use with a catheter, has a hub and a tube through which the catheter extends, and a lock assembly which has a rotational knob that actuates a plurality of prongs arranged in a radial pattern around a hole in the hub that receives the catheter, wherein the prongs synchronously rotate in one direction to grip the catheter or in the other direction to release the catheter.
Claims20
A sheath introducer for use with a catheter, comprising:
- a hub having a proximal end and a distal end,
- a flexible tube extending from the distal end, the tube adapted for insertion into a patient;
- an opening that communicates with a lumen extending through the hub and the tube, the lumen adapted to receive the catheter;
- and
- a lock assembly having a rotational member and at least one prong adapted to contact a portion of the catheter when the rotational member is rotated in one direction and to release the portion of the catheter when the rotational member is rotated in another direction.

A sheath introducer for use with a catheter, comprising:
- a hub having a proximal end, a distal end,
- a flexible tube extending from the distal end, the tube adapted for insertion into a patient;
- a lumen extending through the hub and the tube;
- a valve proximal of the tube;
- an end cap mounted over the valve onto the proximal end, the end cap having a neck portion with pins extending therefrom and
- a lock assembly, the assembly having a rotational member mounted on the neck portion, and a plurality of prongs rotationally mounted on the pins and rotationally coupled to the rotational member, the prongs being adapted to compress a portion of the catheter when the rotational member is rotated in one direction and to release the portion of the catheter when the rotational member is rotated in another direction.

A sheath introducer for use with a catheter, comprising:
- a hub having a proximal end, a distal end,
- a flexible tube extending from the distal end, the tube adapted for insertion into a patient;
- a lumen extending through the hub and the tube;
- an end cap mounted on the hub, the end cap defining an opening for the lumen;
- and
- a lock assembly having a rotational member mounted on the end cap, and a plurality of prongs mounted on the end cap, each of the prongs being rotatable about a respective rotational axis,
- wherein the rotational member has a cam pin for each of the prongs, the cam pins being adapted to rotate each prong in response to rotation of the rotational member by a user so as to compress a portion of the catheter when the rotational member is rotated in one direction and to release the portion of the catheter when the rotational member is rotated in another direction.
