Abstract
A catheter shaft includes a proximal portion with a first polymer having a first stiffness and a first portion of a tubular braid component extending within the first polymer, an intermediate portion with a second polymer having a second stiffness and a second portion of the tubular braid component extending within the second polymer, and a distal portion with a third polymer having a third stiffness, a third portion of the tubular braid component extending within the third polymer, and a hypotube extending within the third polymer. The hypotube is configured for elastic deformation and includes a sidewall cut with a pattern. Along an overlap segment of the distal portion, the third portion of the tubular braid component and the hypotube overlap each other. The outer shaft is configured for improved torque transmission.
