Abstract
A flexible circuit that is substantially planar may be assembled into an electrophysiologic catheter. The flexible circuit may include various location sensing portions and force sensing portions. The flexible circuit may be deformed in a manner that improves the catheter's functionality concerning force feedback and location feedback, and then further deformed to be assembled into a small volume of the catheter.
Claims14
A flexible circuit, comprising:
- a substrate fabricated via a lithographic process such that the substrate comprises between a first number of layers and a second number of layers, the substrate including a first portion and a second portion;
- the first portion comprising a first first-portion segment and a second first-portion segment, the first first-portion segment having a first shape and the second first-portion segment having a second shape that is a mirror image of the first shape;
- and
- the second portion comprising a first second-portion segment and a second second-portion segment, the first second-portion segment having a third shape and the second second-portion segment having a fourth shape that is a mirror image of the third shape,
- in which the first first-portion segment, the second first-portion segment, the first second-portion segment, and the second second-portion segment are comprised from the same layers of the substrate.
