Kink resistant introducer with mapping capabilities
First Claim
1. An introducer system for use with at least one of a catheter and a lead, the introducer system comprising:
- a sheath having a first end and a second end, the sheath being compatible for insertion within a body, wherein the sheath defines a central lumen configured to permit introduction of at least one of a lead and a catheter therethrough;
wherein at least a portion of the sheath is configured to define a flexible, kink-resistant section;
wherein the flexible, kink-resistant section comprises a helical pleat on an outer surface of the sheath defining a helical groove;
a mapping probe at the first end of the sheath connectable to a pacing system analyzer for seeking at least one of an epicardial surface location and an endocardial location at which optimal pacing parameters can be determined; and
at least one conductor received in the helical groove of the sheath connected to and extending from the mapping probe to the pacing system analyzer.

Abstract
An introducer system for use with a pacemaker lead includes a plastic sheath compatible for insertion within a body, a first end configured for insertion into the body with a second end extending out of the body. A central lumen of the sheath is configured to permit introduction of the lead and includes a flexible, kink-resistant section smooth on its outer surface with a helical pleat defining a helical groove enabling a conductor extending from the mapping probe to the pacing system analyzer to be received in the helical groove of the sheath. A mapping probe at the first end of the sheath is connectable to a pacing system analyzer for seeking a location on the myocardial surface of the heart or an endocardial location at which optimal pacing parameters can be achieved prior to implantation of the lead.
