Abstract
A lead fixation tool includes a tapered opening for receiving and guiding a stylet into a lead. The fixation tool also includes an engagement mechanism for gripping a portion of the lead connector so that rotation of the tool causes rotation of an active fixation tip, such as a helical tip, coupled with the lead.
Claims44
A lead fixation tool comprising:
- a proximal portion having a tapered passage therethrough;
- and
- a distal portion having a channel in substantially axial alignment with the passage and having a lead pin engagement mechanism.
A lead fixation tool comprising:
- means for gripping a lead;
- and
- means for aligning the lead with a passageway.
A tool comprising:
- means for receiving a stylet;
- means for receiving a lead aligned with the means for receiving the stylet;
- and
- means for gripping the lead.

A lead fixation tool comprising:
- a proximal portion having a guide passage disposed therethrough, wherein the guide passage includes a tapered portion having an opening and a lumen interface;
- and
- a distal portion having a connector channel that is axially aligned with the guide passage;
- an engagement collar disposed within the connector channel that is configured for gripping and axially aligned with the guide passage.

The fixation tool of clam 17, wherein the proximal portion is rotatably coupled with the distal portion.
A lead fixation tool comprising:
- a housing having a generally circular cross section, the housing including a proximal portion and a distal portion, wherein the proximal portion and the distal portion are axially aligned;
- a guide passage for receiving stylet and extending between an opening in the proximal portion to a lumen interface, wherein the guide passage tapers from a larger diameter at the opening to a narrower diameter;
- a lead receiving channel disposed within the distal end for receiving at least a portion of a connector assembly of a lead;
- a connector pin channel disposed within the lead receiving channel for receiving a connector pin of the connector assembly and axially aligning the connector pin with the lumen interface;
- and
- an engagement collar defining the connector pin channel and configured to grip the connector pin.
3 more elements
A method of manipulating a lead comprising:
- inserting a lead connector of a lead having a lumen opening into a distal portion of a fixation tool that grips the lead connector and aligns the lumen opening with a guide passage disposed within a proximal portion of the fixation tool;
- inserting a stylet through the proximal portion of the fixation tool and into the lumen opening;
- and
- rotating the fixation tool to cause rotation of an active fixation lead tip coupled with the lead.
