Hypotube shaft with articulation mechanism
First Claim
1. A device for delivering a medical aid into a patient, the device comprising:
- an anchor having proximal and distal ends;
an arm connected to the distal end of the anchor and having a first lumen, the arm being rotatable about a single axis only relative to the anchor, the axis being substantially perpendicular to the first lumen;
a pull wire having proximal and distal ends, the pull wire distal end being mechanically coupled to the arm;
a hollow shaft having proximal and distal ends, the anchor being sized to fit within the hollow shaft distal end, at least a portion of the hollow shaft distal end being proximal to the axis;
a flexible sleeve radially overlying the axis and the hollow shaft distal end; and
a flexible tube extending through the first lumen, the flexible tube having a second lumen, wherein the arm is in a first position when the pull wire distal end is in a first position and the arm is in a second position when the pull wire distal end is in a second position.

Abstract
A delivery device for a prosthetic heart valve includes a shaft, a sheath, and a pull wire. The shaft has a proximal end, a distal end, and a longitudinal axis. The sheath is attached to the shaft and is rotatable about an axis transverse to the longitudinal axis of the shaft. The pull wire is mechanically coupled to the sheath such that movement of the pull wire rotates the sheath relative to the shaft. The sheath may be in a first position relative to the shaft when a distal end of the pull wire is in a first position and may be in a second position when the distal end of the pull wire is in a second position. Deflection of the sheath relative to the shaft enables a prosthetic valve to be axially aligned with the native valve annulus for deployment.

11. A device for delivering a medical aid into a patient, the device comprising:
- an anchor having proximal and distal ends;
an arm connected to the distal end of the anchor at a joint and having a first lumen, the joint defining a pivot axis for pivoting the arm relative to the anchor, the pivot axis being substantially perpendicular to the first lumen;
a pull wire having a distal end coupled to the arm and a proximal end;
a hollow shaft having proximal and distal ends, the anchor being sized to fit within the hollow shaft distal end, at least a portion of the hollow shaft distal end being proximal to the pivot axis;
a flexible sleeve radially overlying the pivot axis and the hollow shaft distal end; and
a flexible tube extending through the first lumen, the flexible tube having a second lumen, wherein the arm is in a first position when the pull wire is in a first position and the arm is in a second position when the pull wire is in a second position. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A device for delivering a medical aid into a patient, the device comprising:
-
an anchor having proximal and distal ends; an arm connected to the distal end of the anchor and having a first lumen, the arm being rotatable about a single axis only relative to the anchor, the axis being substantially perpendicular to the first lumen; a pull wire having proximal and distal ends, the pull wire distal end being mechanically coupled to the arm; a hollow shaft having proximal and distal ends, the anchor being sized to fit within the hollow shaft distal end; and a flexible tube extending through the first lumen, the flexible tube having a second lumen, wherein a portion of the pull wire extends along an outer surface of the anchor such that the portion of the pull wire is directly adjacent to the hollow shaft, and wherein the arm is in a first position when the pull wire distal end is in a first position and the arm is in a second position when the pull wire distal end is in a second position.
