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.
Claims20
A method of assembling a catheter including a planar flexible circuit, comprising:
- receiving the planar flexible circuit, the planar flexible circuit including a planar substrate fabricated via a lithographic process such that the planar substrate comprises between one and ten layers, the planar substrate including:
- a first portion comprising a force-sensing coil,
- a second portion comprising a first planar location coil, and
- a third portion comprising a second planar location coil,
- in which the first portion, the second portion, and the third portion are comprised from the same layers of the planar substrate;
- orienting the first portion to be parallel to a face of a spring oriented transversely to a longitudinal axis of the spring;
- affixing the first portion to the face of the spring;
- orienting the second portion and the third portion to be parallel, respectively, to two outer surface portions of a coupling sleeve;
- and
- affixing the second portion and the third portion to the two outer surface portions of the coupling sleeve.
