Description

The proximal shaft is a polymer coated stainless steel tube. The steel construction is designed to optimize proximal pushability with a smooth transition to a distal shaft specifically designed to be highly trackable. A lubricious coating is applied to the distal section. The semicompliant balloon material allows dilatation with precise control of balloon diameter and length. Two radiopaque platinum marker bands are located within the balloon segment. The catheter is compatible with 5F or larger guiding catheters. The internal lumen of the catheter accepts a standard 0.**4 inch PTCA guidewire. The proximal part of the guidewire enters the catheter�s tip and advances coaxially out the catheter�s proximal port, thereby allowing both coaxial guidance and rapid exchange of catheters with a single standard length guidewire. Two marked sections are located on the hypotube shaft to indicate catheter position relative to the tip of either a brachial or femoral guiding catheter. The design of this dilatation catheter does not incorporate a lumen for distal dye injections or distal pressure measurements. The product can be used to expand stenotic coronary vessel, and improve myocardial bleeding. This kind of balloon catheter possesses such merits as moderate compliance, high pressure resistance, minor diameter, etc.
