Abstract
Guidewires and thin-film catheter-sheaths, fabricated using vacuum deposition techniques, which are monolayer or plural-layer members having ultra-thin wall thicknesses to provide very-low profile delivery assemblies for introduction and delivery of endoluminal devices.
Claims39
A method of manufacturing one of a guidewire and a catheter-sheath having a body, the method comprising:
- (a) providing a substrate having a surface capable of accommodating metal deposition thereon and having a substrate geometry corresponding at least in part to a geometry desired for the body;
- (b) depositing a thin-film of a biocompatible metal onto the substrate using a vacuum deposition technique, the thin-film forming the body;
- and
- (c) removing the substrate from the body formed thereon.
9 The method of claim 8, wherein removing the substrate comprises etching the sacrificial material.
A guidewire having a body, wherein the body comprises a thin-film of a biocompatible metal formed by a vacuum deposition technique.
A catheter-sheath having a generally tubular body, wherein the body comprises a thin-film of a biocompatible metal formed by a vacuum deposition technique.
An assembly for delivering a medical device via a patient's vascular system, the assembly comprising:
- (a) a medical device;
- (b) a guidewire having a guidewire body, the guidewire body comprising a first thin-film of a first biocompatible metal formed by a vacuum deposition technique;
- and
- (c) a catheter-sheath having generally tubular catheter-sheath body, the catheter-sheath body comprising a second thin-film of a second biocompatible metal formed by a vacuum deposition technique, the catheter-sheath body defining a catheter-sheath lumen;
- wherein the guidewire is positioned coaxially within the lumen of the catheter-sheath, and wherein the medical device is concentrically positioned within a distal portion of the catheter-sheath lumen and intermediate the catheter-sheath body and the guidewire body, thereby forming the assembly.
