摘要:
Apparatus and methods for securing a therapy delivery device relative to a burr hole. In one embodiment, the apparatus includes a base that is securable to bone, without the use of fasteners, either before or after insertion of the therapy delivery device into the burr hole. The apparatus may further include a stabilizer that may be engaged with both the base and the therapy delivery device while the delivery device is held with positioning apparatus. The base and/or stabilizer may frictionally engage the delivery device, e.g., receive it with interference, to secure the device in two or more non-parallel directions. In some embodiments, at least the stabilizer may include a surface coating or treatment operable to enhance frictional engagement with the therapy delivery device.
摘要:
A system, comprising a lead configured to deliver electrical stimulation to a brain having a housing defining a longitudinal axis and a circumference, a ring electrode that encircles an entirety of the circumference of the lead housing disposed at a first axial position along the longitudinal axis of the lead housing and a plurality of electrodes disposed at respective different positions around the circumference of the lead housing, wherein the plurality of electrodes are disposed at a second axial position different than the first axial position along the longitudinal axis of the lead housing; a user interface; and a processor configured to present on the user interface at least one view of a representation of the lead and to receive user input via interaction with the at least one view for defining stimulation for delivery by the lead.
摘要:
The disclosure describes a method and system that generates stimulation parameters by selecting one or more stimulation parameters according to a stimulation field defined by a user. The system includes a memory that stores a plurality of stimulation templates for multiple electrode configurations of an electrical lead. A processor selects one or more volumetric stimulation templates that best match, e.g., fill, the three-dimensional stimulation field defined by the clinician. Each stimulation template is associated with a set of stimulation parameters that can be used to deliver stimulation therapy to a patient.

摘要:
The disclosure describes a method and system that allows a user to configure electrical stimulation therapy by defining a stimulation field. After a stimulation lead is implanted in a patient, a clinician manipulates a stimulation field on the display to encompass desired anatomical regions of the patient. In this manner, the clinician determines which anatomical regions to stimulate, and the system generates the necessary stimulation parameters. In some cases, a lead icon representing the implanted lead is displayed to show the clinician where the lead is relative to anatomical regions of the patient.

The disclosure describes a method and system that allows a user to configure electrical stimulation therapy by defining a three-dimensional (3D) stimulation field. After a stimulation lead is implanted in a patient, a clinician manipulates the 3D stimulation field in a 3D environment to encompass desired anatomical regions of the patient. In this manner, the clinician determines which anatomical regions to stimulate, and the system generates the necessary stimulation parameters. In some cases, a lead icon representing the implanted lead is displayed to show the clinician where the lead is relative to the 3D anatomical regions of the patient.
摘要:
An implantable cardioverter for providing cardioversion electrical energy to at least one chamber of a patient's heart in need of cardioversion and applying a pain alleviating therapy at an appropriate site in the patient's body prior to or in conjunction with the delivery of the cardioversion energy to the heart chamber to alleviate propagated pain perceived by the patient. The combined cardioversion and pain alleviating therapies are preferably realized in a single implantable, multi-programmable medical device or separate implantable cardioversion and pain control devices with means for communicating operating and status commands between the devices through the patient's body.
