Apparatus for baroreceptor stimulation therapy
First Claim
1. A medical apparatus, comprising:
- an implantable lead for stimulation of a target region of a patient'"'"'s nervous system, the lead comprising;
a generally tubular lead body having a proximal end, an opposite distal end, a stylet lumen and a conductor lumen, the stylet and conductor lumens extending through the proximal and distal ends of the tubular lead body;
a conductor enclosed within the conductor lumen;
an electrode assembly extending from the distal end of the lead body, the electrode assembly including a flexible polymeric carrier, and an electrode on the carrier and electrically coupled to the conductor; and
a stylet sized and shaped to be receivable within the stylet lumen and configured to stiffen and support the lead body, wherein the stylet includes a proximal portion and a distal portion, wherein a temporary anchoring element is coupled to a distal end of the distal portion of the stylet, wherein the temporary anchoring element is configured to extend from, and retract into, the distal end of the stylet.

Abstract
A medical apparatus comprising an implantable lead and a stylet configured for stimulation of a target region of a patient'"'"'s nervous system is described. The lead includes a generally tubular lead body, a conductor, and an electrode assembly. The generally tubular lead body has a stylet lumen and a conductor lumen extending through the proximal and distal ends of the lead body. The conductor is enclosed within the conductor lumen. The electrode assembly extends from the distal end of the lead body. The electrode assembly includes a flexible polymeric carrier and an electrode on the carrier and electrically coupled to the conductor. The stylet is sized and shaped to be receivable within the stylet lumen and configured to stiffen and support the lead body. The distal portion of the stylet includes a bend having a predetermined angle of incidence relative to the proximal portion of the stylet.

12. A method of implanting an implantable lead for stimulation of the baroreceptors located within a carotid sinus of a patient, the method comprising:
-
advancing a stylet into a stylet lumen of a lead body of the implantable lead, the lead body comprising the stylet lumen and a conductor lumen, wherein a conductor is enclosed within the conductor lumen, and wherein the stylet is sized and shaped to be receivable within the stylet lumen, wherein the stylet is configured to stiffen and support the lead body and includes a proximal portion and a distal portion, wherein a temporary anchoring element is coupled to a distal end of the distal portion, and wherein the temporary anchoring element is configured to extend from, and retract into, the distal end of the stylet; and positioning an electrode of the implantable lead proximate to a target physiological region of a patient by using the stylet to stiffen and support the lead body, wherein the electrode is electrically coupled to the conductor at a distal end of the conductor. - View Dependent Claims (13, 14, 15, 16)
