Medical device having bonding regions and method of making the same
First Claim
1. A medical device comprising:
- a first member made from nitinol having a first surface with an available surface oxygen;
a second member made from nitinol having a second surface with an available surface oxygen;
a bonding agent comprised of polyhydroxyl ether having a plurality of secondary hydroxyl functional groups with an affinity to form hydrogen bonds with oxygen, the bonding agent being cooperatively associated with the first member and the second member in such a manner as to cause the bonding agent to contact the first surface and the second surface, the bonding agent configured to affix the first member relative to the second member by forming a covalent bond between the available surface oxygen on the first and the second surfaces and the hydroxyl functional groups of the bonding agent.

Abstract
Medical devices having bonded joints are disclosed. The bonded joints include two surfaces bonded by a layer of phenoxy resin therebetween. In the preferred embodiments, bonded surfaces include materials that are suitable for medical devices. Most preferably, Nitinol includes at least one bonded surface, however, other preferred materials may include, but are not limited to cobalt chromium, stainless steel, titanium, tantalum, and plastic. An intraluminal device including a plurality of locations with a phenoxy resin layer is also disclosed wherein the phenoxy resin further includes a radioopaque additive, a lubricious additive, or both radioopaque and lubricious additives. Also disclosed is an intraluminal device having contiguous heterogeneous structural elements of metallic members and non-metallic sections that are bonded together by a layer of phenoxy resin therebetween.
