Abstract

An integrated catheter stripper is mounted within a modified Y-connector (10) that is used to seal a catheter (12) on a guide wire (14). The connector (10) is provided with a stripping port (20) that opens into the central bore of the main body of the connector. A catheter slitter (46) is mounted over the guide wire within the central bore of the main body for slitting the catheter (12) as the catheter (12) slides in the proximal direction along the guide wire (14) within the main body. The split catheter (12) is removed through the stripping port (20), which can be sealed during an angioplasty operation when the catheter is in use. In non-integrated embodiments of the invention the catheter stripper is separate from the Y-connector and has a main body (70), a blade (52) mounted in the main body (70), and an arrangement for aligning the catheter (12) with the blade (52) and for permitting mounting and separation of the blade (52) relative to the catheter (12) only by substantially longitudinal movement. In one embodiment, a stylet (66) is securely attached to the main body portion (70) and extends into the proximal end of the catheter (12) as it is pulled from the guide wire (14). In another embodiment, a guide tube (50), rather than a stylet, is secured to the main body and encircles the guide wire (14). The guide tube is pushed into the proximal end of the catheter (12) (while the catheter is still on the guide wire) and a blade (52) slits the catheter (12).
