The present invention provides a length of trilayer, extruded, medical tubing comprising an outer layer, a core layer, and an intermediate tie layer. The outer layer comprises a polymer that is directly bondable, while the core layer comprises a lubricious polymer. The core layer thus defines a lumen that exhibits the desired characteristics, i.e., low friction for the advancement of a guidewire or catheter through the lumen without comprising the strength and stiffness that is desirable in tubing that is to be used in medical devices. Additionally, the tubing is easily coextruded and yet, is not subject to delamination, thus providing the added advantage of providing a reduction in the overall cost of manufacture.

Trilayer, extruded medical tubing and medical devices incorporating such tubbing

A vascular dilatation catheter including an elongated catheter shaft having a distal and a proximal end and a first lumen extending therethrough fluid connection with a distally located balloon and a second lumen capable of receiving a guidewire is provided with a clip device attached about a proximal portion of the catheter shaft and adapted to releasibly secure the catheter shaft in a coiled configuration between uses.
