An implantable medical device, such as a sensor for monitoring a selected internally detectable physiological parameter of a patient, is attached to a fixation assembly that is deployable within the patient to position and orient the sensor to enable it to perform its function. The fixation assembly is formed having at least one flexible asymmetric connector where each fixation member includes a plurality of loops, wherein a first loop of the plurality of loops has a maximum pitch that is different from a maximum pitch of a second loop of the plurality of loops. The attachment of the housing and the fixation assembly includes providing a tubular member that is welded to the housing and crimped over a section of the fixation assembly.

Implantable medical sensor and fixation system

Devices, systems, and techniques are described for creating pockets in tissue for accepting implantable medical devices. For example, a surgical tool includes a shaft defining a proximal end, a distal end, and a longitudinal axis, a handle coupled to the proximal end of the shaft, and one or more blades configured to move between a retracted configuration and a deployed configuration, wherein the one or more blades extend, in the deployed configuration, substantially perpendicular to the longitudinal axis at the distal end of the shaft. The one or more blades may be configured to separate tissue in the deployed configuration.

Devices and techniques for separating tissue

In an example, the disclosure describes a system with a lead having a proximal end and a distal end and an elongated lead body. The lead has one or more electrodes. A fixation member is located on the elongated lead body and is configured to secure the lead to tissue within a patient. The fixation member is located on the lead so the fixation member is closer to the proximal end than the one or more electrodes of the lead. A trialing adaptor receives the proximal end of the lead and is removable when a trialing period is completed. A sheath encloses at least a portion of the lead and covers the fixation member. The sheath is configured to remain in place over the lead during the trialing period.

Communication power in a medical device system is managed by providing power from a power supply to a communication circuit in a sensing device according to a first communication wake up mode set for a first time period and according to a second communication wake up mode set for a second time period. The second communication wake-up mode is established by a second device.

Ultralow-power implantable hub-based wireless implantable sensor communication

Media-exposed interconnects for transducer modules are disclosed. The transducers may be sensing transducers, actuating transducers, IC-only transducers, or combinations thereof, or other suitable transducers. The transducers may be used in connection with implantable medical devices and may be exposed to various media, such as body fluids. The media-exposed interconnects for transducer modules may allow transducers to communicate electrically with other components, such as implantable medical devices.

Media-exposed interconnects for transducers

This disclosure describes antenna structures for use with implantable medical devices (IMDs). The IMD may include a housing that hermetically encloses electronic components of the IMD and a fixation mechanism that attaches the IMD to a target location within a patient, such as a wall of a vessel. The fixation mechanism may function as a radiating element of an antenna of the IMD. The fixation mechanism may be attached to a housing of the IMD with two different members. One member may be an anchoring structure that mechanically anchors the fixation mechanism to the housing. The second member may be a connector that electrically connects the fixation mechanism to the housing such that the fixation mechanism is configured to transmit and/or receive communication signals with other implantable or external devices.

Antenna structures for implantable medical devices

This disclosure relates to implantable medical devices (IMDs); in particular, to medical electrical leads having an integrated sensor disposed in a hermetic package and said sensor package accommodates a torque coil and an elongated cable conductor extending therethrough.

The coil and the cable can couple to pacing and sensing electrode coupled to the lead distal to the sensor package. The sensor package is compact, substantially circular in cross section and robust, in that the overall design promote mechanical stability.
