A medical system for obstructive sleep apnea (OSA) treatment includes therapy delivery circuitry configured to output one or more electrical stimulation signals to a tongue of a patient; sensing circuitry configured to sense one or more compound muscle action potential (CMAP) signals, wherein the one or more CMAP signals are generated in response to the delivery of the one or more electrical stimulation signals; and processing circuitry configured to: cause the therapy delivery circuitry to output the one or more electrical stimulation signals to the tongue; receive information indicative of the one or more CMAP signals from the sensing circuitry; determine, based on the one or more CMAP signals, one or more therapeutic stimulation parameters for the OSA treatment; and cause the therapy delivery circuitry to deliver therapeutic electrical stimulation signals according to at least the determined one or more therapeutic stimulation parameters.

A custom length stylet assembly for meeting medical device length tolerances. The custom length stylet assembly including a stylet wire having a length extending between a distal end and a proximal end, stylet handle defining a longitudinally oriented throughbore sized to retain a proximal portion of the stylet wire, the stylet handle further defining a proximately positioned track and tab, the track configured to retain a bent proximal end portion of the stylet wire, the length of the stylet wire selected during assembly of the stylet assembly to conform to the corresponding length of a body implantable lead within a predefined tolerance, the tab of the stylet handle melted into the track, thereby securely fastening stylet wire to the stylet handle to inhibit rotation or dislodgement.

This document discusses, among other things, examples of a low profile instrument immobilizer and means for positioning the same. In one example, the low profile instrument immobilizer grasps, secures, and immobilizes an electrode or other instrument that extends through a burr hole in a skull to a target location in a patient's brain.

Tips for use on a tunneling tool provide the ability to pull an implantable medical lead extension or catheter body through a subcutaneous tunnel. The tips may include a pin with a barb, where the barb is inserted within a compliant portion of a connector body of the lead extension or a catheter body to create an interference fit that allows the connector body or catheter body to be pulled through the tunnel. The tips may include a carrier that has a cavity for the connector body, where the tunneling is performed with the carrier present on the tunneling tool. A body is positioned within the cavity of the carrier to prevent tissue from snagging on and collecting within the carrier. The body may include a tip portion that performs the tunneling function. The carrier may also provide tunneling and/or may be attached to the tunneling tool during tunneling.

Tools and methods for implantation of implantable medical lead extensions or catheters

Devices and methods provide accurate targeting, placement, and/or stabilization of an electrode or other instrument(s) into the brain or other body organ, such as to treat severe tremor or other neurological disorders. Targeting is performed using any form of image-guidance, including real-time MRI, CT, or frameless surgical navigation systems.

Device for immobilizing a primary instrument and method therefor

An implantable medical lead includes a lead body having a proximal portion and a distal portion. The lead also includes first and second contacts located at the proximal portion of the lead body, and includes first and second electrodes located at the distal portion of the lead body. The first electrode is electrically coupled to the first contact and the second electrode is electrically coupled to the second contact. The first contact has a proximal end and a distal end and the second contact has proximal end and a distal end. The second contact is radially spaced apart from the first contact. The contacts do not extend around the lead body. This disclosure also relates to an implantable lead extension and to an implantable signal generator having connectors configured to receive the present lead.

Lead having radially spaced apart contacts to allow for adjustability

An implantable medical lead includes a lead body having a proximal portion and a distal portion. The lead also includes first and second contacts located at the proximal portion of the lead body, and includes first and second electrodes located at the distal portion of the lead body. The first electrode is electrically coupled to the first contact and the second electrode is electrically coupled to the second contact. The first contact has a proximal end and a distal end and the second contact has proximal end and a distal end. The second contact is radially spaced apart from the first contact. The contacts do not extend around the lead body. This disclosure also relates to an implantable lead extension and to an implatable signal generator having connectors configured to receive the present lead.

An alignment device and method is provided. Higher precision is achieved when fixing an orientation of an insertion axis using alignment devices shown. A symmetric clamping force is provided that reduces or eliminates unwanted displacement after the desired orientation is obtained. Another feature includes increased flexibility to use a variety of primary medical devices. Another feature includes a standoff feature that reduces tissue damage. Another feature includes an orienting fixture for image guided procedures.

Ball and socket trajectory guide

A system can be used to navigate or guide an instrument or device into an anatomy of a patient. The navigation can occur with the use of image data acquired of the patient. The image data can be registered to the patient space for navigation. Also, one or more coils can be used for tracking or localization.

Method and apparatus for performing a navigated procedure

A trajectory guide assembly that guides an instrument relative to a patient includes a mounting seat configured to be supported by the patient. The assembly also includes a trajectory member moveably supported by the mounting seat. The trajectory member defines a trajectory passage. Also, the assembly includes a cap member moveably supported by the trajectory member. The cap member defines a cap opening, and the cap member is selectively moveable to a first position relative to the trajectory member to retain the instrument in both the cap opening and the trajectory passage. Additionally, the cap member is selectively moveable to a second position relative to the trajectory member to release the instrument.
