US 6,299,596 B1 · Method of bonding polymers and medical devices comprising materials bonded by said method

Abstract

A method of bonding polymeric materials, in particular, polymeric materials comprising silicone, is provided along with medical devices comprising materials bonded together by said method. More specifically, the method of the present invention involves surface treating the surface of a polymeric material, preferably a polymeric material comprising silicone, such that the character of the surface of the material changes in a manner such that bondability of the material is enhanced. The surface of the surface treated polymeric material is then brought into contact with the surface of a second polymeric material and optionally, an adhesive, under conditions effective to bond the surfaces together. The bond so formed is stronger than a corresponding bond between untreated polymeric materials.

Dependent claims

A medical catheter, comprising:

(a) a first polymeric body in the form of a first tube and comprising a first surface of silicone that has been subjected to an oxidative plasma surface treatment under conditions effective to functionalize at least a portion of the surface with chemically reactive moieties;
(b) a second polymeric body in the form of a second tube and comprising a second surface, said first and second tubes being fitted one within the other such that the second surface is in a confronting relationship to the first surface;
and
(c) a cured compatible adhesive bonding said first surface to said second surface.
