According to one embodiment, a flexible drill includes a lower sub-assembly connected to an upper sub-assembly, where the lower sub-assembly comprises a retainer tube and the upper sub-assembly comprises a guiding tube; a drilling tip, and capable of orienting the drilling tip at a predetermined position after accessing a material to he drilled through a substantially straight passage having a lone axis. The predetermined position is at least 10° off of the lone axis of the substantially straight passage. According to one embodiment, a method of drilling a material includes the steps of (a) providing a flexible drill; (b) advancing the drill through a substantially straight passage until the drilling tip accesses the material to be drilled, thereby orienting the drilling tip at the predetermined position; and (c) actuating the drill.

摘要： A bidirectional steerable catheter is provided that can be deflected to form two different curves, i.e., two curves each having a different radius of curvature. The catheter comprises an elongated, flexible tubular catheter body having proximal and distal ends and a lumen extending therethrough. A tip section is provided at the distal end of the catheter body. The tip section comprises a flexible plastic tubing having at least first and second off-axis lumens extending therethrough. A control handle is attached to the proximal end of the catheter body. A first puller wire extends through the lumen of the catheter body and the first off-axis lumen of the tip section. The first puller wire has a distal end anchored in the tip section and a proximal end anchored to the control handle. A second puller wire extends through the lumen of the catheter body and the second off-axis lumen of the tip section. The second puller wire has a distal end anchored in the tip section and a proximal end anchored to the control handle. A first compression coil extends through the lumen of the catheter body in surrounding relation to the first puller wire. The first compression coil has a distal end anchored in the catheter body or in the first off-axis lumen of the tip section at a first anchor position. A second compression coil extends through the lumen of the catheter body in surrounding relation to the second puller wire and into the second off-axis lumen. The second compression coil has a distal end anchored in the second off-axis lumen of the tip section at a second anchor position that is distal to the first anchor position. By this design, the radius of curvature of each curve achieved by deflection of the tip section is controlled by the anchor position of the compression coil surrounding the appropriate puller wire.

摘要： An electrophysiology catheter (20) comprises a shaft (22) having a first bending stiffness and a deflectable tip (28) secured to the distal end (24) of the shaft with a second bending stiffness less than the first bending stiffness. At least one electrode (34, 36) is mounted to the tip for delivering current to or monitoring electrical activity of tissue. A manipulator wire (58) is coupled to the distal end of the deflectable tip, whereby the deflectable tip may be deflected by axial force applied to the manipulator wire. A stiffener member (66) is axially slidable relative to the tip so as to adjust the tip curvature without removing the catheter from the body. The catheter may further include a core wire (72) configured to rotate the deflectable tip about a longitudinal axis (2) without rotating the proximal end (26) of the catheter shaft, wherein the distal end of the deflectable tip remains in a substantially constant axial position, preferably in a plane perpendicular to the longitudinal axis.
