SIDE PORT LEAD DELIVERY SYSTEM
First Claim
1. A lead delivery system for implanting a lead in a patient'"'"'s internal jugular vein (IJV) through a subclavian vein, the system comprising:
- an outer catheter having a distal portion, an intermediate portion, and a proximal portion, the outer catheter defining a lumen extending through the proximal portion to a side port located on the intermediate portion, the distal portion including a support region for leveraging against a wall of a superior vena cava (SVC) of the patient;
an inner catheter sized to slide within the lumen and out the side port, the inner catheter including a distal curve configured to facilitate access to the IJV; and
a guidewire sized to slide within a lumen of the inner catheter;
wherein the lumen and the side port are configured to direct the inner catheter towards an entrance to the IJV when the outer catheter is inserted with the support region in place against the SVC.

Abstract
A lead delivery system for implanting a lead in a patient'"'"'s internal jugular vein (IJV) through a subclavian vein. The system comprises an outer catheter having a distal portion, an intermediate portion, and a proximal portion.

The distal portion includes a support region for leveraging against a wall of a superior vena cava (SVC) of the patient. An inner catheter is sized to slide within the lumen and out the side port. The inner catheter includes a distal curve configured to facilitate access to the internal jugular vein. A guidewire is sized to slide within a lumen of the inner catheter. The lumen and side port are configured to direct the inner catheter towards the entrance to the IJV when the outer catheter is inserted with the support region in place against the SVC.
