Abstract:
The catheter of the invention generally has component parts made of polymeric materials and a fusion bond between these catheter parts containing a compatibilizing material which enhances the miscibility of the polymeric materials to facilitate the formation of the fusion bond. The catheter parts formed of polymeric materials may not be sufficiently miscible to readily form a fusion bond. The compatibilizing material increases the miscibility of the catheter parts in the molten state to effect the fusion bond between the polymeric materials. Chemical primer and plasma surface treatments may be used to provide the catheter parts to be bonded with functional groups which improve miscibility with the compatibilizing material.
