Claims
- 1. An intraluminal catheter, comprising:a) a first catheter part comprising a multilayered tubular member having an inner layer formed of a lubricious polymeric material a low melting point middle layer formed of an adhesive polymer with a melting point lower than a melting point of the inner layer polymeric material, and an adjacent polymeric layer which is bonded to an outer surface of the middle layer and which forms an outer layer; and b) a second catheter part having at least a section bonded to a distal section of the middle layer of the multilayered tubular member.
- 2. The catheter of claim 1 wherein the adhesive polymer comprises a polyolefin based copolymer formed from a polyolefin with up to about 35% by weight of a comonomer having reactive groups.
- 3. The catheter of claim 1 wherein the adhesive polymer comprises a polyethylene based adhesive polymer.
- 4. The catheter of claim 2 wherein the comonomer is selected from the group consisting of carboxylic acid, acrylic acid, maleic acid, and anhydrides thereof.
- 5. The catheter of claim 1 wherein the middle layer of the multilayered tubular member is formed of an ethylene-acrylic acid copolymer.
- 6. The catheter of claim 1 wherein the outer layer of the multilayered tubular member is formed of a material selected from the group consisting of polyethylene, polyethylene terephthalate, polyamide, thermoplastic polyurethane, and polyetheretherketone.
- 7. The catheter of claim 1 wherein the inner layer of the multilayered tubular member has a static coefficient of friction of less than about 0.35.
- 8. The catheter of claim 1 wherein the inner layer of the multilayered tubular member has a static coefficient of friction of less than about 0.30.
- 9. The catheter of claim 1 wherein the inner layer of the multilayered tubular member is thicker than the outer layer.
- 10. The catheter of claim 1 wherein the outer layer of the multilayered tubular member is thinner than the middle layer.
- 11. The catheter of claim 1 wherein the middle layer of the multilayered tubular member is thinner than the inner layer.
- 12. The catheter of claim 1 wherein the second catheter part is a skirt of a balloon.
- 13. The catheter of claim 1 wherein the second catheter part is formed of a material selected from the group consisting of polyolefin, polyester, polyamide and copolymers thereof.
- 14. The intraluminal catheter of claim 1 further comprising a third catheter part having at least a section bonded to a distal section of the outer layer of the multilayered tubular member.
- 15. An intraluminal catheter, comprising:a) an elongated shaft formed at least in part by a multilayered tubular member which at least in part defines a guidewire lumen, the multilayered tubular member having an inner layer informed of a lubricious polymeric material, a middle layer formed of an adhesive polymer with a melting point lower than a melting point of the inner layer polymeric material, and an adjacent polymeric layer which is bonded to an outer surface of the middle layer and which forms an outer layer; and b) a non-traumatic distal tip on a distal end of the shaft formed by a tubular member having an outer layer and an inner layer which is secured to the middle layer of the multilayered tubular member or the distal end thereof.
- 16. The intraluminal catheter of claim 15 further comprising a balloon having at least a section bonded to a distal section of the outer layer of the multilayered tubular member.
- 17. An intraluminal catheter, comprising:a) a first catheter part comprising a multilayered tubular member having an inner layer formed of a lubricious polymeric material, a middle layer formed of an adhesive polymer with a melting point lower than a melting point of the inner layer polymeric material, and an adjacent polymeric layer which is bonded to an outer surface of the middle layer, and which forms an outer layer which has a thickness less than a thickness of the middle layer; and b) a second catheter part having at least a section bonded to a distal section of the middle layer of the multilayered tubular member.
- 18. The intraluminal catheter of claim 17 wherein the outer layer thickness is less than a thickness of the inner layer.
