Puncture guard for catheter wire
First Claim
1. In a catheterization system adapted for percutaneous catheterization of a patient'"'"'s blood vessel, and wherein the system includes an adaptor through which one end of an occluding wire is inserted into the blood vessel and the other end remains outside of the patient, a puncture guard for protecting the medical practitioner from being accidentally punctured by the end of the wire that remains outside of the patient, and which does not interfere with the bending characteristics of the wire, the puncture guard comprising:
- a first portion which comprises an elongated, hollow covering means for completely enclosing therewithin the end of the wire that remains outside of the patient in order to protect a medical practitioner from accidental puncture, said first portion further comprising a flexible, resilient material that is sufficiently bendable so as not to interfere with the bending characteristics of the wire; and
a second portion which comprises a means for securing the first portion to the adaptor.

11. In a catheterization system adapted for percutaneous catheterization of a patient'"'"'s blood vessel, and wherein the system includes an adaptor through which a one end of an occluding wire is inserted into the blood vessel and the other end remains outside of the patient, a puncture guard for protecting the medical practitioner from being accidentally punctured by the end of the wire that remains outside of the patient, and which does not interfere with the bending characteristics of the end of the wire, the puncture guard comprising:
-
a first portion which comprises an elongated, hollow cylindrically shaped member that has sufficient length to completely enclose therewithin the end of the wire that is outside of the patient, in order to protect a medical practitioner from accidental puncture, said first portion further comprising a flexible, resilient material that is sufficiently bendable so as not to interfere with the bending characteristics of the wire; and
a second portion which comprises a flange, the first and second portions being joined to one another and the flange comprising means for coupling the puncture guard to the adaptor. - View Dependent Claims (12, 13, 14)
