Abstract
An implantable medical system includes an implantable catheter advanceable into a coronary sinus of a patient's heart. A guide element and an implantable lead receivable in the side lumen is advanceable through an angled opening of the catheter to be deflected laterally away from the catheter at the deflection angle to position the at least one testing electrode or at least one pacing electrode, respectively, in a myocardium of the patient's heart when the distal portion of the catheter is positioned in the coronary sinus.
Claims20
An implantable medical system comprising:
- an implantable catheter advanceable into a coronary sinus of a patient's heart, the catheter comprising a sheath body extending between a proximal portion and a distal portion, the catheter comprising a side lumen and an angled opening proximal to the distal portion in fluid communication with the side lumen, wherein the side lumen and the angled opening define a deflection angle configured to deflect a guide element and an implantable lead advanced therethrough proximate to a region of the cardiac conduction system in the myocardium of the patient's heart;
- the guide element receivable in the side lumen, the guide element extending from a proximal portion to a distal portion, wherein the distal portion includes at least one testing electrode, wherein the guide element is advanceable through the angled opening to be deflected laterally away from the catheter at the deflection angle to position the at least one testing electrode proximate the region of the cardiac conduction system in a myocardium of the patient's heart when the distal portion of the catheter is positioned in the coronary sinus;
- and
- the implantable lead receivable in the side lumen, the lead comprising a lead body extending from a proximal portion to a distal portion, wherein the implantable lead comprises an anchoring element disposed along the lead body and at least one pacing electrode disposed along the distal portion, wherein the at least one pacing electrode is configured to pace the region of the cardiac conduction system of the patient's heart, wherein the lead is advanceable through the angled opening to be deflected laterally away from the catheter at the deflection angle to implant the at least one pacing electrode proximate the region of the cardiac conduction system in the myocardium of the patient's heart to pace the cardiac conduction system of the patient's heart.
