Abstract
A vascular catheter having a central lumen adapted to slidably receive a guidewire therein with an inflatable collar or other suitable means to releasably secure or fix the guidewire within the lumen so that the catheter and guidewire can be advanced through a patient's vasculature as a unit. The catheter system is particularly suitable in balloon dilatation catheters for use in percutaneous transluminal coronary angioplasty procedures.
