ABSTRACT:
The present invention is a method of making a radio-opaque tipped, sleeved guidewire. It includes providing a bendable core piece of a predetermined length, having a control end and a distal end and having a predetermined core diameter, and providing a shrinkable polymeric sleeve formed of a first polymer composition having a first diameter at least as large as said core diameter and having a second, smaller diameter from shrinking said second diameter, which is less than said core diameter. The polymeric sleeve is placed over the core piece while the polymeric sleeve has its first diameter, so as to have one end of the polymeric sleeve cover at least a portion of the distal end of the core piece. Next, a mixture of a radio-opaque metal powder and a second polymer composition is provided. The second polymer composition is capable of forming a physical bond with the first polymeric composition of the polymeric sleeve. The mixture is inserted into the overhanging polymeric sleeve at the distal end of the core piece and the polymeric sleeve is shrunk to its second, smaller diameter. The physical bond is formed between the first polymer composition and the second polymer composition. The present invention is also directed to the resulting guidewire products.
