US Patent:

20210330233, Oct 28, 2021

Filed:

Jul 9, 2021

Appl. No.:

17/372016

Inventors:

- Yokneam, IL
Shubhayu Basu - Anaheim CA, US
Stuart Williams - Ontario CA, US
Cesar Fuentes-Ortega - Pasadena CA, US

International Classification:

A61B 5/287
A61B 18/14
A61B 5/00
A61B 18/00
A61M 25/00

Abstract:

An electrophysiology catheter with a distal electrode assembly having covered spine carrying a plurality of microelectrodes. One or more spines have preformed configurations including at least a first portion with a first curvature and a second portion with a second curvature, and may include a linear portion. The linear portion may be between the first and second portions. The linear portion may be distal of the first and second portions. One or more spines have a narrower portion so that different portions of the spine can have different flexibility with a degree of independence in flexibility from adjacent portions.

Appl. No.:

15/454775

Inventors:

- Yokneam, IL
Sungwoo Min - Fullerton CA, US
Stuart Williams - Ontario CA, US
Marisa Borja - Pasadena CA, US

International Classification:

A61B 5/00
A61B 5/042

Abstract:

Aspine that may be used in the electrode assembly of an electrophysiologic catheter having controlled flexibility. The spine may have a flexible core that extends through a length of the spine, a polymeric cover and a plurality of electrodes, each having at least one lead, distributed longitudinally along the spine. An amount of material forming the spine may be adjusted longitudinally along the spine to compensate for changes in flexibility to the spine caused by varying numbers of electrode leads present at different relative longitudinal positions along the spine.
