INTRODUCER FOR THERAPY DELIVERY ELEMENTS
First Claim
1. A method comprising:
- inserting an introducer into a patient, the introducer comprising an elongated body having a proximal end and a distal end for insertion into tissue of the patient, the elongated body defining a lumen;
advancing the distal end of the elongated body through tissue of the patient to a position within the patient proximate to a therapy delivery site;
introducing fluid proximate the distal end of the elongated body to create a space proximate to the therapy delivery site,advancing a paddle lead carrying one or more pad electrodes from the proximal end of the elongated body to the distal end of the elongated body through the lumen to position the pad electrodes within the space proximate to the therapy delivery site.

Abstract
The disclosure describes an introducer for facilitating implantation of therapy elements into a patient. The introducer has an elongated body that defines a lumen for advancement of a therapy element to an implant site, and includes a curved portion medially located between substantially straight proximal and distal portions. As an example, the shape of the introducer may allow a clinician to more easily, and without substantially damaging surrounding tissue, find the correct tissue depth and follow that tissue depth to the implant site. For example, the introducer may facilitate implantation of a therapy element within or between desired layers of tissue of the patient. In some embodiments, fluid may be injected through the introducer to create a space within the tissue to implant the therapy element. Fluid may also be evacuated through the introducer prior to implantation.

11. An introducer to facilitate implantation of a therapy element into a patient comprising:
-
an elongated body having a proximal end and a distal end for insertion into tissue of the patient, wherein the elongated body defines a lumen sized for insertion of the therapy element from the proximal end to the distal end through the lumen, and a handle protruding from a proximal portion of the elongated body to allow a clinician to control insertion and advancement of the introducer, wherein the handle provides a surface that is normal to the direction of advancement to allow the clinician to apply force substantially in the direction of advancement. - View Dependent Claims (12, 13, 14)

15. A kit comprising:
-
an introducer to facilitate implantation of a therapy element into a patient including an elongated body having a proximal end and a distal end for insertion into tissue of the patient, wherein the elongated body defines a lumen sized for insertion of the therapy element from the proximal end to the distal end through the lumen; and a stylet sized to substantially fill the lumen to prevent coring of tissue during an implantation procedure, wherein a distal end of the stylet includes a pointed tip for tissue dissection, wherein all sides of the stylet are tapered at its distal end. - View Dependent Claims (16, 17, 18, 19, 20)
