Systems, devices, and techniques are described for adjusting electrical stimulation based on detected ECAPs. In one example, a medical device includes processing circuitry configured to control stimulation circuitry to deliver a first electrical stimulation pulse and sensing circuitry to detect, after delivery of the first electrical stimulation pulse, an ECAP signal. The processing circuitry may be configured to determine a characteristic value of the ECAP signal, determine an ECAP differential value that indicates whether the characteristic value of the ECAP signal is one of greater than a selected ECAP characteristic value or less than the selected ECAP characteristic value, determine, based on the ECAP differential value, a gain value, determine, based on the gain value, a parameter value that at least partially defines a second electrical stimulation pulse, and control the stimulation circuitry to deliver the second electrical stimulation pulse according to the parameter value.
Techniques are disclosed for delivering electrical stimulation therapy to a patient. In one example, a medical system delivers electrical stimulation therapy to a tissue of the patient via electrodes. The medical system determines a first change of a first sensed signal of the patient to movement by the patient and a second change of a second sensed signal of the patient to the movement by the patient. Based on the first change and the second change, the medical system selects one of the first sensed signal and the second sensed signal of the patient for controlling the electrical stimulation therapy. The medical system adjusts a level of at least one parameter of the electrical stimulation therapy based on the selected one of the first sensed signal and the second sensed signal.
A lift, a head support, and methods for use thereof for use with a surgical frame are provided. The lift and the head support can be used with the surgical frame that is capable of reconfiguration before, during, or after surgery. The surgical frame can include a main beam that can be rotated, raised/lowered, and tilted upwardly/downwardly to afford positioning and repositioning of a patient supported thereon, and the lift and the head support can be used in lifting the patient from a table/gurney and positioning the patient with respect to the main beam.
A surgical guide is provided comprising a body defining a first cavity that is configured for disposal of a surgical instrument and an opening. A connector is disposable with the opening and is engageable with a surgical robot. At least one insert is disposable in the first cavity. The at least one insert defines a second cavity configured for disposal of an alternate surgical instrument. Systems, methods, spinal constructs, implants and surgical instruments are disclosed.
An adjustable rotational connector is configured to establish electrical communication between an implantable medical lead and a cable of an external testing device while allowing rotation of the implantable medical lead relative to the cable. The coupling includes a pin that is electrically conductive. An adjustable socket is positioned within the pin and is configured to receive lead connectors of different sizes. A bearing is configured to facilitate rotation of the pin relative to the cable. An actuatable element surrounds at least a portion of the adjustable socket. The actuatable element is configured to transition between a first and second position relative to the adjustable socket to allow the adjustable socket to receive and secure the lead connector of the implantable medical lead in the adjustable socket.
A61N 1/375 - Constructional arrangements, e.g. casings
A61N 1/05 - Electrodes for implantation or insertion into the body, e.g. heart electrode
H01R 13/62 - Means for facilitating engagement or disengagement of coupling parts or for holding them in engagement

Systems, devices, methods, and techniques are described for using evoked compound action potential (ECAP) signals to monitor lead position and/or detect lead migration. An example system includes sensing circuitry configured to sense an ECAP signal, and processing circuitry. The processing circuitry controls the sensing circuitry to detect, after delivery of an electrical stimulation pulse, a current ECAP signal, and determines one or more characteristics of the current ECAP signal. The processing circuitry also compares the one or more characteristics of the current ECAP signal to corresponding one or more characteristics of a baseline ECAP signal, and determines, based on the comparison, a migration state of the electrodes delivering the electrical stimulation pulse. Additionally, the processing circuitry outputs, based on the migration state, an alert indicative of migration of the electrodes.
Subcutaneous implantation tools and methods of implanting a subcutaneous device using the same. The tool may include a tool body having a longitudinally extending recess having a distal opening and having a tunneler at a distal end of the tool body extending from the distal opening of the recess. The tool may include a plunger slidably fitting within at least a portion of the tool body recess. The recess may be configured to receive an implantable device and the tunneler preferably extends distally from the recess at a position laterally displaced from the device when the device is so located in the recess. Movement of the plunger distally within the recess advances the device distally out of the recess and alongside of and exterior to the tunneler.
A crimper for altering an implantable medical device from an uncompressed state to a compressed state. The crimper includes a plurality of crimper elements that define a crimper channel, each of the crimper elements including a non-planar surface that forms a portion of the crimper channel. Each non-planar surface is configured to apply non-uniform radial compression along a length of the implantable medical device during operation of the crimper when altering the implantable medical device from the uncompressed state to the compressed state. The crimper also includes handle configured to operate the crimper. Actuation of the handle decreases a volume of the crimper chamber to transition the implantable medical device from the uncompressed state to the compressed state.
