Patent ID: 7766868

Claim:
A medical therapy delivery device, comprising: a shaft formed by an outer layer and including a first non-deflectable portion and a second portion extending distally from the first portion, the second portion deflectable relative to the first portion; a deflectable tip extending distally from the second portion between a proximal end and a distal tip, and having a tapered portion located between the proximal end and the distal tip; a manipulator wire extending through the shaft to adjust deflection of the second portion of the shaft relative to the first portion; a thru lumen tubing forming a thru lumen to transfer one of an elongated mechanical structure and a fluid through the device, wherein the outer layer forms a single shaft lumen having a first lumen portion positioned about the thru lumen tubing and a second lumen portion, offset from and in fluid communication with the first lumen portion, the second lumen portion having a first side wall, a second side wall and a bottom wall extending between the first side wall and the second side wall; an anchoring device, positioned along a distal end of the second portion, fixedly engaged with the manipulator wire; a transition tubing forming a transition lumen, the transition tubing positioned within the second lumen portion and extending between the first portion and the second portion of the shaft to provide a stiffness transition between the first portion and the second portion of the shaft, the manipulator wire extending through the transition lumen; and a compressible member positioned between a distal end of the transition tubing and the anchoring device, wherein the manipulator wire extends through the compressible member and the compressible member is free to move relative to the manipulator wire and the shaft during deflection of the second portion of the shaft, and wherein the thru lumen tubing, the first side wall, the second side wall and the bottom wall positioning the manipulator wire within the second lumen portion.
