Abstract
Retention devices for use with an implantable medical device (IMD) are disclosed. An illustrative retention device may comprise an elongate body including a hollow lumen configured to receive a lead of the IMD and an outer surface configured to receive a suture. The retention device may also include a securing mechanism configured to push against tissue of a patient.

A method of implanting an implantable lead in a patient comprising the use of an implantable lead having a first end for coupling to an implantable medical device and a second end for implantation at a target site in the patient, with a lead body extending therebetween and a retention device for use with an implantable medical device (IMD), the retention device comprising:
- an elongate body having a proximal end, a distal end, a hollow lumen extending from the proximal end to the distal end configured to receive a lead of the IMD, and an outer surface having a first recess configured to receive a suture for tying purposes to secure the retention device at a desired location on the lead;
- and
- one or more securing mechanisms each having a first end and a second end each coupled to the elongate body and an intermediate section between the first end and the second end configured to push against tissue of a patient;
- wherein the method comprises:
- inserting the implantable lead into the patient with the retention device placed on the lead at a desired location thereon and with a sheath disposed about at least a portion of the lead and compressing the one or more securing mechanisms of the retention device in a delivery configuration;
- and
- at least partly withdrawing the sheath such that the one or more securing mechanisms move to a deployed configuration to anchor the implantable lead to tissue of the patient.
A retention device for use with an implantable medical device (IMD), the retention device comprising:
- an elongate body having a proximal end, a distal end, a hollow lumen extending from the proximal end to the distal end configured to receive a lead of the IMD, and an outer surface having a first recess;
- and
- a first securing mechanism having first and second ends configured to extend over and around at least a portion of the elongate body and an intermediate section between the first end and the second end configured to push against tissue of the patient, wherein the first recess is adapted to receive at least one end of the first securing mechanism.
A method of implanting an implantable lead in a patient comprising the use of an implantable lead having a first end for coupling to an implantable medical device and a second end for implantation at a target site in the patient, with a lead body extending therebetween and the retention device adapted for placement on the lead body, the method comprising:
- inserting the implantable lead into the patient with the retention device placed on the lead at a desired location thereon;
- and
- sliding the first end of the first securing mechanism toward the second end of the first securing mechanism causing the intermediate section of the first securing mechanisms to move radially away from the elongate body to a deployed configuration to anchor the implantable lead to tissue of the patient,
- wherein the retention device comprises:
- an elongate body having a proximal end, a distal end, a hollow lumen extending from the proximal end to the distal end configured to receive a portion of the lead, and an outer surface having a first recess;
- and
- a first securing mechanism having first and second ends configured to extend over and around at least a portion of the elongate body and an intermediate section between the first end and the second end configured to push against tissue of the patient, wherein the first recess is adapted to receive at least one end of the first securing mechanism.
