Abstract
A guiding catheter system (10) is provided that includes a Tuohy-Borst fitting (20) attached as a one-piece construction to a guiding catheter tube (11). The guiding catheter system (10) can also include a dilator (16) and a guide wire 15. The Tuohy-Borst fitting (20) can have a side arm (14) onto which a stop cock (30) can be attached. With the stop cock (30) in its closed position, fluid flow through the side arm (14) is prevented. When the nut (22) on the Tuohy-Borst fitting (20) is tightened down so that the gland (24) in the Tuohy-Borst fitting (20) seals against the guide wire (15) and the stop cock (30) is closed, blood loss through the proximal end of the guiding catheter system (10) can be essentially eliminated. Since the Tuohy-Borst fitting (20) is integrally joined to the proximal end of the guiding catheter tube (11), the need for a separately packaged and sterilized Tuohy-Borst fitting to be screwed onto the guiding catheter's proximal end is eliminated. The dilator (16) with the guide wire (15) can be used to allow percutaneous insertion of the guiding catheter system (10) into a patient's artery without requiring an introducer sheath, thus reducing the size of the hole that is made in the wall of the artery. A smaller hole in the artery's wall reduces the possibility of post-procedure bleeding at that point where the guiding catheter system (10) is inserted.
