Abstract

The present invention generally relates to a medical device and procedure for accurately positioning a catheter across a desired region within a patient's vasculature. In particular, the present invention provides a hub assembly unit that allows a physician to precisely position a stent within a vessel utilizing a stent delivery catheter. The hub assembly unit includes a fine adjustment mechanism. The fine adjustment mechanism extends or contracts the length of the hub assembly unit in controlled incremental units. These controlled fine displacements are then translated directly to the stent delivery or balloon dilation catheter.

Description

CROSS-REFERENCE TO CO-PENDING APPLICATIONS

[0001] This application is a continuation of U.S. application Ser. No. 09 / 784,762, filed Feb. 15, 2001.FIELD OF THE INVENTION

[0002] The present invention generally relates to a medical device for positioning a stent delivery or dilatation balloon catheter within the vascular system of a patient. More specifically, the present invention discloses a hub assembly unit providing an operator the ability to finely adjust the positioning of a stent delivery or a balloon dilation catheter within a patient's vascular system. BACKGROUND OF THE INVENTION

[0003] Percutaneous Transluminal Coronary Angioplasty (PTCA) is a well-established procedure for dilating stenosed vessel regions within a patient's vasculature. In this procedure, a balloon angioplasty catheter is introduced into the vasculature, typically through an incision in the femoral artery in the groin. The balloon catheter is then advanced through the femoral artery, through the aortic arch...
