Abstract

A guide wire feeding device for operation by a single hand of a physician is disclosed. The device includes an elastic locking ring which allows the guide wire to be fixed in relative position with the feeding device if desired.

Claims

1. A hand held guide wire feeding device for feeding a guide wire from a flexible guide wire storage tube into a body cavity of a patient, said device comprising:

a longitudinal base member having a storage tube attachment member formed at a proximal end thereof which is attachable to the flexible guide wire storage tube, a straightening barrel member formed at a distal end of said longitudinal base member, and an open central section positioned between said storage tube attachment member and said straightening barrel member;

at least one elevated stopping shoulder located in said open central section of said longitudinal base member; and

an elastic ring member positioned around said longitudinal base member at said open central section thereof;

whereby, said elastic ring member can be moved from a first position relative to said at least one elevated stopping shoulder to a second position relative to said at least one elevated stopping shoulder and wherein a guide wire passing along said longitudinal base member is free to move relative thereto when said elastic ring member is in said first position, and is compressed against said longitudinal base member when said elastic ring member is in said second position.

2. The hand held guide wire feeding device of claim 1 wherein said elastic ring member contacts a portion of said straightening barrel member when in said first position.

3. The hand held guide wire feeding device of claim 1 further including a handle member attached to said longitudinal base member.

4. The hand held guide wire feeding device of claim 3 wherein said handle further includes a clamp for attachment to the flexible storage tube of the guide wire.
