Patent attributes
A steerable, or curveable, introducer drill to access a target treatment region within bone along a curved trajectory is disclosed. The drill may include a drive shaft including a proximal rotational member, a distal drill tip, and an elongate shaft portion extending from the proximal rotational member to the distal drill tip. The distal drill tip may be sharp and include cutting flutes. The drill may also include an outer tube surrounding the drive shaft. A distal end portion of the outer tube may include a segmented tube section configured to facilitate controlled bending of the segmented tube section of the outer tube. The drill may also include an actuator operably coupled to the drive shaft and adapted to apply tension to the drive shaft which, in turn, causes the segmented tube section of the outer tube to bend.
