ABSTRACT:
An over-the-wire catheter includes a catheter that is formed with a lumen for receiving a guidewire therethrough. A slit, which is formed along the guidewire lumen to provide external access into the lumen, extends at least part way along the length of the catheter. A connector, which is formed with an orifice for receiving the catheter therethrough, also includes a grip. In operation, the guidewire is pre-positioned as desired. An end of the guidewire is then passed through the orifice of the connector and is inserted into the guidewire lumen of the catheter. The distal end of the catheter is then inserted over the wire and through the orifice of the connector. Next, the grip on the connector is inserted through the slit and into the guidewire lumen for fixed engagement with the guidewire. The catheter is then advanced through the orifice of the connector and over the guidewire. As the catheter is advanced, the grip slides along the slit of the catheter lumen to maintain a fixed relationship between the guidewire and the connector.
