Abstract

Abstract A guidewire retention device for use with a catheter or other medical device is disclosed herein. The guidewire retention device can be connected to a standard adapter at the proximal end of the catheter. It has an opening therein which can be placed in communication with the catheter lumen. This opening includes a large diameter portion and a small diameter portion and is preferably keyhole shaped. The large diameter portion allows a guidewire to easily pass therethrough while the small diameter portion does not. Thus, when a guidewire is located in the catheter lumen in the proper position, the guidewire can be fitted into the small diameter portion of the keyhole shaped opening to lock the guidewire with respect to the catheter. A raised icon on the guidewire retention device provides an indication to the clinician of how to use the guidewire retention device. <IMAGE>
