LOW PROFILE MEDICAL DEVICES WITH INTERNAL DRIVE SHAFTS THAT COOPERATE WITH RELEASABLY ENGAGEABLE DRIVE TOOLS AND RELATED METHODS
First Claim
Patent Images
1. A medical device comprising:
- an elongate body having opposing proximal and distal end portions with an axially extending center cavity;
an internal drive shaft residing in the center cavity, the drive shaft having a proximal end portion with a rotatable spline residing in the proximal end portion of the elongate body; and
an extendable member held in the distal end portion of the elongate body, the extendable member in communication with the drive shaft, whereby rotation of the drive shaft causes the extendable member to extend out of the elongate body.

18. A method of advancing an extendable member from a medical lead, comprising:
-
matably engaging an integral spline of a disposable single-use drive tool with an intrabody medical lead having an internal drive shaft and spline; turning the drive tool to rotate the drive shaft; and rotating the extendable member from the lead in response to the turning step. - View Dependent Claims (19)

20. An implantable pacemaker lead comprising:
-
a pacemaker lead having opposing proximal and distal end portions with an axially extending center cavity; an internal rotatable and translatable drive shaft residing in the center cavity, the drive shaft having a proximal end portion with a rotatable spline, the spline residing in the proximal end portion of the lead; and an extendable member held in a retracted configuration in the distal end portion of the lead, the extendable member in communication with the drive shaft, whereby rotation of the drive shaft causes the extendable member to extend out of the lead. - View Dependent Claims (21)

22. A single-use disposable medical drive tool having an internal spline or spline engagement member sized and configured to slidably releasably receive and engage an end portion of an intrabody medical lead having an internal drive shaft with an end having a spline or spline engagement portion configured to engage the drive tool spline or spline engagement member, the drive tool further comprising a cavity for receiving a stylet, the tool being configured to allow a user to both rotate and translate the internal drive shaft of the medical lead, wherein the medical drive tool is held in a sterile package.
