Implant tools with attachment feature and multi-positional sheath and implant techniques utilizing such tools
First Claim
1. A system comprising:
- a medical lead, wherein the medical lead comprises;
a lead body having a proximal end and a distal end, wherein the proximal end of the lead body is configured to connect to a medical device, and wherein the distal end of the lead body includes one or more electrodes; and
an implant tool for implanting the medical lead, wherein the implant tool comprises;
a rod that includes;
a handle;
a shaft having a proximal end adjacent to the handle and a distal end, wherein the shaft is formed with a groove that extends into the shaft to define 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.

20. A system comprising:
-
a medical lead; and an implant tool for implanting the 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, wherein the shaft of the rod has a diameter that is greater than a diameter of the medical lead, and wherein the shaft is formed with a groove that extends into the shaft to define 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, the body of the sheath having an inner diameter that is less than or equal to the diameter of the rod such that the sheath and shaft of the rod create an interference fit, 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. - View Dependent Claims (21)

22. A system comprising:
-
a rod that includes; a handle; a shaft having a proximal end adjacent to the handle and a distal end, wherein the shaft is formed with a groove that extends into the shaft to define an attachment feature toward the distal end of the shaft, the attachment feature configured to couple to the medical lead; 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; and an implantable medical lead that includes one or more electrodes along a distal portion of the medical lead, wherein at least one of the shaft of the rod and the body of the sheath includes one or more markings that identify locations that coincide with locations of the one or more electrodes of the medical lead when the medical lead is placed within the sheath such that a distal end of the medical lead is located at the distal end of the body of the sheath.
