Abstract
A catheter with a first component, a second component, and a glue line disposed between the components which is filled with an adhesive layer joining the components. The adhesive layer is formed in two plies, whereby a first adhesive ply is bonded to the first component and a second adhesive ply is bonded to the first adhesive ply and to the second component. Thus, even catheter components which could not be bonded to each other with the use of a single-ply adhesive layer or could only be bonded with inadequate stability can be firmly bonded to each other. Moreover, one of the adhesive plies may be applied in the unassembled state of the components.
Claims14
A catheter with a first component formed of a first material and a second component formed of a second material, wherein the first material has different adhesion characteristics than the second material, with a portion of a surface of each component aligned to form a space disposed between the components which is filled with an adhesive layer joining the components, wherein the adhesive layer is formed in two plies, whereby a first adhesive ply is bonded to the first component and a second adhesive ply is bonded to the first adhesive ply and to the second component, wherein said first ply has different adhesion characteristics than said second ply to form a more stable bond between the first and second materials than would otherwise be formed with only one adhesive ply.
A catheter having a first component with a first surface defined thereon and a second component having a second surface defined thereon, the first component having different adhesion characteristics than the second component, said first and second surfaces aligned with a space therebetween filled with a first adhesive ply and a second adhesive ply, wherein the first ply has different adhesion characteristics than the second ply, wherein the first ply is more readily bondable to the second ply than the second surface.
A catheter having a first component with a first surface defined thereon and a second component having a second surface defined thereon, said first and second surfaces aligned with a space therebetween filled with a first adhesive ply which is cured by application of light energy and a second adhesive ply which is cured by addition of moisture.
