Abstract
In some examples, an implantable medical device includes an implantable housing, a neurostimulator within the housing, a plurality of electrodes, an implantable lead coupled to the housing, and an actuator formed with the housing. The implantable lead includes at least one electrode of the plurality of electrodes and one or more conductors coupling the at least one electrode to the neurostimulator. The actuator is configured to cause at least a portion of the implantable lead to deflect.
Claims19
An implantable medical device comprising:
- a housing, including a channel disposed therein;
- a neurostimulator associated with the housing;
- a lead coupled to the housing, the lead including an electrode and one or more conductors coupling the electrode to the neurostimulator;
- an actuator coupled to the channel of the housing, the actuator configured to cause at least a portion of the lead to deflect;
- and
- a pull-wire connected to a distal portion of the lead and connected to the actuator, wherein the actuator is configured such that movement of the actuator in a first direction increases tension on the pull-wire to cause the deflection of at least the distal portion of the lead.

An implantable medical device comprising:
- a housing;
- a neurostimulator associated with the housing;
- a lead coupled to the housing, the lead including an electrode and one or more conductors coupling the electrode to the neurostimulator;
- an actuator operably connected to the housing,
- wherein operation of the actuator is configured to cause at least a portion of the lead to deflect;
- and
- a pull-wire connected to a distal portion of the lead and connected to the actuator, wherein the actuator is configured such that movement of the actuator in a first direction increases tension on the pull-wire to cause the deflection of at least the distal portion of the lead.
4 more elements
A kit, comprising:
- an implantable neurostimulator including:
- a housing, including a channel disposed therein;
- a lead coupled to the housing, the lead including an electrode and one or more conductors coupling the electrode to the housing;
- and
- an actuator coupled to the channel of the housing, the actuator including a rotatable screw and a key, wherein the key is configured to translate within the channel,
- a pull-wire connected to a distal portion of the lead and connected to the key of the actuator;
- and
- a tool configured to engage the rotatable screw of the actuator,
- wherein the actuator is configured such that rotation of the screw causes translation of the key within the channel so as to increase or decrease tension on the pull-wire and deflect or straighten at least the distal portion of the lead.
