IMPLANT TOOLS WITH ATTACHMENT FEATURE AND MULTI-POSITIONAL SHEATH AND IMPLANT TECHNIQUES UTILIZING SUCH TOOLS
First Claim
1. An implant tool for implanting a medical lead, the implant tool comprising:
- a rod that includes;
a handle;
a shaft having a proximal end adjacent to the handle and a distal end; and
an attachment feature toward the distal end of the shaft, the attachment feature configured to couple to the medical lead; and
a sheath configured to be placed on the rod, wherein the sheath includes a body having proximal end and a distal end, and further wherein the sheath is configured to be placed in multiple positions along the rod including a first position in which the sheath does not interact with the attachment feature and second position in which the sheath does interact with the attachment feature.

Abstract
Implant tools and techniques for implantation of a medical lead, catheter or other implantable component are provided. The implant tools and techniques are particularly useful in implanting medical electrical leads in extravascular locations, including subcutaneous locations. An example implant tool for implanting a medical lead includes a rod and a sheath configured to be placed on the rod. The rod includes a handle, a shaft having a proximal end adjacent to the handle and a distal end, and an attachment feature toward the distal end of the shaft, the attachment feature configured to couple to the medical lead. The sheath is configured to be placed in multiple positions along the rod including a first position in which the sheath does not interact with the attachment feature and second position in which the sheath does interact with the attachment feature.

15. A method for implanting a medical electrical lead using a rod having a handle, a shaft having a proximal end adjacent to the handle and a distal end, and an attachment feature toward the distal end of the shaft, the attachment feature configured to couple to the medical lead, and a sheath configured to be placed on the shaft of the rod, the sheath having body defining a channel, the medical electrical lead having a proximal end including a connector mechanism configured to connect to an implantable medical device and a distal end including one or more electrodes, the method comprising:
-
creating a first incision at a first location on a torso of a patient; creating a second incision at a second location on the torso of the patient; introducing the rod, with the sheath placed on the rod at a first position in which the sheath does not interact with the attachment feature of the rod, into the patient via the first incision; advancing the rod from the first incision to the second incision to create a first path between the first incision and the second incision; attaching an attachment feature of the medical electrical lead to the attachment feature of the rod; advancing the sheath to a second position in which the sheath does interact with the attachment feature of the rod after attaching the attachment feature of the medical electrical lead to the attachment feature of the rod; withdrawing the rod from the patient to pull the medical electrical lead along the path between the first incision to the second incision; retracting the sheath to the first position such that the sheath no longer interacts with the attachment feature of the rod; and removing the attachment feature of the medical electrical lead from the attachment feature of the rod. - View Dependent Claims (16, 17, 18, 19, 20)
