First Claim
Patent Images
1. A steerable delivery device comprising:
- a steerable portion adapted to be steered; and
an outer sheath and an inner sheath disposed within the outer sheath along a first portion of the delivery device, the outer sheath comprising a first material and the second sheath comprising a second material, wherein the first and second materials are merged together at a merged location distal to the steerable portion, forming a unitary section of material at the merged location, wherein the inner and outer tubular members are adapted to be axially moved relative to one another along the steerable portion to steer the steerable portion.

11. A steerable delivery device comprising:
-
a steerable portion adapted to be steered; and an outer sheath and an inner sheath disposed within the outer sheath, wherein the outer sheath and the inner sheath are permanently axially fixed relative to one another at a location distal to the steerable portion, and wherein, in the steerable portion, the outer sheath comprises a tubular member with a first portion with a plurality of slots formed therein in a first pattern and a second portion with a plurality of slots formed therein in a second pattern different than the first pattern. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A steerable delivery device comprising:
-
a steerable portion adapted to be steered; an outer sheath and an inner sheath disposed within the outer sheath and axially fixed to the outer sheath at a first location distal to the steerable portion, wherein the inner and outer tubular members are adapted to be axially moved relative to one another along the steerable portion to steer the steerable portion; and a tensioning element secured to the inner sheath at a first location proximal to the steerable portion and secured at a second location where the inner and outer sheaths are axially fixed relative to one another, the tensioning element disposed radially between the outer and inner sheaths in the steerable portion, wherein the tensioning element is adapted to add axial stiffness to the steerable portion when the inner and outer sheaths are moved relative to one another when steering the steerable portion. - View Dependent Claims (19, 20, 21, 22, 23, 24)

25. A steerable delivery device comprising:
-
an outer sheath and an inner sheath disposed within the outer sheath, wherein the inner sheath includes a first tubular element; a steerable portion adapted to be steered; wherein along the steerable portion the first tubular element includes a first section of a first material with a first durometer and a second section of a second material with a second durometer different than the first durometer, wherein the first and second sections are disposed at different radial portions of the first tubular element. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A steerable delivery device comprising:
-
a steerable portion adapted to be steered; an outer sheath and an inner sheath disposed within the outer sheath, the sheaths are axially fixed relative to one another distal to the steerable portion, and are adapted to be axially moved relative to one another along the steerable portion to steer the steerable portion; a wire element secured to the inner sheath and to the outer sheath; and a pulley secured to an external actuator, wherein the wire element extends around the pulley and is adapted to be actuated to steer the steerable section. - View Dependent Claims (37, 38, 39, 40, 41)
