First Claim
1. A lead introducer comprising:
- an outer needle comprising an outer needle body and an outer needle hub coupled to the outer needle body, the outer needle body defining an open channel extending along a longitudinal length of the outer needle body, andan inner needle comprising an inner needle body configured and arranged for sliding along the open channel of the outer needle and an inner needle hub coupled to the inner needle body, the inner needle body defining a lumen extending along a longitudinal length of the inner needle body;
a splittable member comprising a splittable member body and a splittable member hub and having a distal end, the splittable member configured and arranged for disposing over the outer needle body and the inner needle body and for being longitudinally splittable, wherein the splittable member hub comprises an interior surface and is configured and arranged to receive at least one or more portions of both the inner needle hub and the outer needle hub within the splittable member hub; and
an annular seal member formed by either a) the inner needle hub or b) a combination of the inner needle hub and outer needle hub, wherein the annular seal member is configured and arranged to form a fluid-resisting seal with the interior surface of the splittable member hub when the at least one or more portions of the inner needle hub and outer needle hub are received within the splittable member hub.

Abstract
One embodiment is a lead introducer including an outer needle, an inner needle, a splittable member, and an annular seal member. The outer needle, inner needle, and splittable member each include a body and hub. The splittable member fits over the outer needle body and the inner needle body and can be separated longitudinally. The splittable member hub receives at least portions of both the inner needle hub and the outer needle hub within the splittable member hub. The annular seal member is formed by either a) the inner needle hub or b) a combination of the inner needle hub and outer needle hub. The annular seal member forms a fluid-resisting seal with the interior surface of the splittable member hub when the portions of the inner needle hub and outer needle hub are received within the splittable member hub.
