摘要:
The present invention concerns a kit of parts and a system for centering an external element with respect to an implantable medical device, said kit of parts comprising: • An implantable medical device (20) for being implanted under the skin of a patient and comprising an internal housing provided with a light source (22) positioned such as to emit a light beam coaxial to a secondary axis (Z2), normal to the skin, • An external element (10) comprising: - a number, N>2, of photodetectors (12a-12d) forming a polygon of N edges, normal to a primary axis (Z1), and - an indicator (4) indicating how the external element is to be displaced over the surface of the skin of a patient in order to position the external element with the primary axis (Z1), being coaxial with the secondary axis (Z2), of the implantable medical device, as a function of the energy received by each of the N photodetectors from the light beam emitted by the light source. The present invention also concerns the corresponding method for aligning said external element and said implantable medical device.
摘要:
An external controller is disclosed for communicating with an external trial stimulator (ETS) for an implantable medical device. The external controller is programmed with a battery algorithm able to assist a clinician in choosing a suitable implant for the patient based on battery performance parameters estimated for a number of implants during an external trial stimulation phase that precedes implantation of the implant. The algorithm is particularly useful in assisting the clinician in choosing between a rechargeable-battery implant or a primary-battery implant for the patient.

Therapy systems for treating a patient are disclosed. Representative therapy systems include a system for treating pain in a patient, the system comprising: an implantable lead; and a pulse generator coupleable to the implantable lead, the pulse generator comprising: a memory, and a database module programmed to store records containing values of a patient status and a stimulation parameter, and a processing module programmed to: during a first phase: analyze the stored records of the patient status and the stimulation parameter, and establish a preference baseline containing preference stimulation parameters corresponding to values of the patient status, during a second phase: automatically adjust an operating parameter of the pulse generator, based at least in part on the preference baseline and an indication of a change in the patient status, to generate and deliver an electrical stimulation signal to the patient's spinal cord via the implantable lead.

The present invention relates to a pulse generating system (10) comprising a pulse generating means (12) for generating a pulse or pulses and a controlling means (14) for controlling the pulse generating means (12), wherein the pulse generating system (10) is capable to work in at least a regular mode and a safety mode, wherein in the regular mode the pulse generating means (12) and the controlling means (14) are connected and wherein in the safety mode there is no connection between the pulse generating means (12) and the controlling means (14) and wherein in the safety mode the pulse generating means (12) automatically switches to a baseline stimulation command.
摘要:
An electrical stimulation system includes a control module that provides electrical stimulation signals to an electrical stimulation lead coupled to the control module for stimulation of patient tissue. The system also includes a sensor to be disposed on or within the body of the patient and to measure a biosignal; and a processor to communicate with the sensor to receive the biosignal and to generate an adjustment to one or more of the stimulation parameters based on the biosignal. The adjustment can be configured and arranged to steer the electrical stimulation signals to stimulate a region of the patient tissue that is different, at least in part, from a region of the patient tissue stimulated prior to the adjustment. Alternatively or additionally, the biosignal is indicative of a particular patient activity and the adjustment is a pre-determined adjustment selected for the particular patient activity.

摘要:
An apparatus comprises a communication channel comprising a plurality of disparate sequential communication links configured to facilitate bi-direction communication between an implantable medical device (IMD) and a programmer. A transceiver is configured to communicate with the programmer via a first communication link of the plurality of disparate communication links. A telemetry device is configured to communicate with the IMD via a second communication link of the plurality of disparate communication links. A third communication link communicatively couples the transceiver and the telemetry device. A power source is coupled to the transceiver and to the telemetry apparatus. An operational status of at least the first and second communication links can be individually determined in real-time.
