Medical device having bonding regions and method of making the same
First Claim
1. A method for fabricating a medical device, the method comprising the steps of:
- providing a first member, the first member having a first surface with an available surface oxygen;
providing a second member, the second member having a second surface with an available surface oxygen;
providing a bonding agent having a plurality of secondary hydroxyl functional groups with an affinity to form hydrogen bonds with the oxygen present on the surface of the first and the second member; and
indirectly affixing the first member and the second member with the bonding agent by heating at least one of the first member, the second member or the bonding agent until (i) forming a covalent bond between the available surface oxygen on the first surface and at least one of the hydroxyl functional groups of the bonding agent, and (ii) forming a covalent bond between the available surface oxygen on the second surface and at least one of the hydroxyl functional groups of the bonding agent.

Abstract
Medical devices comprised of bonded joints are disclosed. The bonded joints comprise two surfaces bonded by a layer of phenoxy resin therebetween. In the preferred embodiments, bonded surfaces are comprised of materials that are suitable for medical devices. Most preferably, Nitinol comprises 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 comprised of a plurality of locations with a phenoxy resin layer is also disclosed wherein the phenoxy resin is further comprised of a radiopaque additive, a lubricious additive, or both radiopaque and lubricious additives. Also disclosed is an intraluminal device comprised of contiguous heterogeneous structural elements comprised of metallic members and non-metallic sections that are bonded together by a layer of phenoxy resin therebetween.
