DEFLECTABLE CATHETER SHAFT SECTION, CATHETER INCORPORATING SAME, AND METHOD OF MANUFACTURING SAME

摘要

A deflectable catheter shaft section is disclosed comprising an elongated body extending along a longitudinal axis and comprising a distal end and a proximal end; and a plurality of lumens extending along the longitudinal axis of the elongated body, wherein at least one of the lumens is abutting at least another one of the lumens. A catheter comprising the deflectable catheter shaft section and a method of manufacturing the deflectable catheter shaft section are also disclosed. A catheter incorporating a deflectable catheter shaft section can further comprise first and second compression coils disposed over pull wires located within the catheter, wherein the compression coils are unattached to the catheter or components thereof, but can be constrained by a shaft coupler at a distal end of each of the compression coils and by at least a portion of a handle assembly at a proximal end of each of the compression coils.

主权项

1. A deflectable catheter shaft section comprising the following:
an elongated body extending along a body longitudinal axis and comprising a distal end and a proximal end; a first pocket at said distal end of said elongated body and configured for attachment of a pull ring and a tip assembly; a second pocket at said proximal end of said elongated body; and a shaft coupler mounted in said second pocket, wherein said shaft coupler defines a coupler longitudinal axis aligned with said body longitudinal axis, and wherein said shaft coupler defines (a) a plurality of coupler lumens extending along said coupler longitudinal axis and (b) an outer radial surface defining a groove.
