Subcutaneous lead fixation mechanisms
First Claim
1. A medical device including an electrode to be subcutaneously placed at a target site in a patient, comprising:
- a lead having a lead body extending from a proximal end to a distal end, the electrode being positioned along the lead;
a housing having a connector block for receiving the proximal end of the lead body;
a fixation tip positioned at the distal end of the lead body; and
a plurality of fixation members extending from the fixation tip from a fixation member proximal end to a fixation member distal end, wherein the plurality of fixation members are capable of being advanced from a first position corresponding to the fixation member distal end being positioned along the lead during subcutaneous placement of the electrode, to a second position corresponding to the fixation member distal end being positioned away from the lead to fixedly engage the electrode at the target site.

Abstract
A medical device that includes a lead having a lead body extending from a proximal end to a distal end, and a housing having a connector block for receiving the proximal end of the lead body. A fixation tip is positioned at the distal end of the lead body, and a plurality of fixation members extend from the fixation tip from a fixation member proximal end to a fixation member distal end. The plurality of fixation members are capable of being advanced from a first position corresponding to the fixation member distal end being positioned along the lead during subcutaneous placement of the lead, to a second position corresponding to the fixation member distal end being positioned away from the lead to fixedly engage the lead at a target site.
