Abstract

Abstract Making a stent in accordance with information regarding tubular living-body tissue of each individual for treating such as aneurysm. A stent A is formed by a mechanical method using a machine tool controlled in accordance with shape-information regarding tubular living-body tissue of each individual so as to match with an inner shape of the tubular living-body tissue of each individual, wherein said shape-information is obtained by a mechanical method such as such as ultrasonic tomogram (US), computer tomography (CT), or magnetic resonance imaging (MRI). More particularly, it is preferable to make the stent A by using a master B being formed in accordance with shape-information of a tubular tissue and having a shape substantially similar to an inner shape of the tubular tissue, and then, restraining the shape of the stent A in correspondence with the master B so as to performing a shape-memorization process.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 45 words
A stent being formed by a mechanical method in accordance with shape-information regarding a tubular living-body tissue of each individual so as to match with an inner shape of the tubular living-body tissue of each individual, wherein said shape-information is obtained by a mechanical method.
Claim 2
Dependent Claim 68 words
A stent being formed to match with an inner shape of a tubular living-body tissue of each individual by performing shape-memorization in a manner corresponding to a master, wherein the master has an inner surface or outer surface with a shape being substantially similar to the inner shape of the tubular living-body tissue of each individual and being formed in accordance with shape-information obtained by a mechanical method.
Claim 3
Independent Claim 89 words
A method of manufacturing a stent so as to manufacture a stent matching with an inner shape of a tubular living-body tissue of each individual by comprising the steps of: obtaining the inner shape-information regarding the tubular living-body tissue of each individual by using a mechanical method; making a master in accordance with the shape-information in which the master has a three dimensional inner surface or outer surface substantially similar to the inner shape of the tubular living-body tissue; and performing shape-memorization in a manner corresponding to the master.
