US 2025/0143770 A1 · THIN FILM MAPPING CATHETER

Abstract

A medical device includes a sheath; a balloon disposed over at least a portion of the sheath; and a flexible framework including an expandable region and a non-expandable region. The expandable region is formed on an inflatable portion of the balloon and includes longitudinal extending arms, each arm including one or more layers of dielectric material, one or more conductive traces, and one or more electrodes electrically connected to the one or more conductive traces. The non-expandable region is formed on a non-inflatable portion of the balloon or the sheath and includes one or more layers of dielectric material, the one or more conductive traces, and one or more contacts electrically connected to the one or more conductive traces. A cable including a plurality of wires that are electrically connected to the one or more contacts.

Dependent claims

A method for deploying a medical device, the method comprising:

inserting the medical device into a cavity of a body, wherein the medical device includes:
a sheath;
an end cap;
a hollow core extending from the sheath to the end cap;
a plurality of thin film elements disposed in a first configuration around the hollow core,
wherein the plurality of thin film elements includes a plurality of mapping electrodes;
and
a travel limiter disposed between the plurality of thin film elements and the hollow core;
providing tension on a pull cable to retract the end cap towards a distal end of the sheath and retract the hollow core within the sheath;
anchoring the travel limiter to the distal end of the sheath;
and
expanding the plurality of thin film elements to a second configuration.
