An implantable medical device may include a plurality of electrical components connected to form operational circuitry, a canister shaped for housing the operational circuitry, and a dampening layer configured to reduce internal motion between the operational circuitry and at least one of a plurality of additional component within the canister, the dampening layer selectively disposed over the operational circuitry but not over the at least one additional component, the dampening layer providing electrical isolation to the operational circuitry, the dampening layer comprising a moldable material in direct contact with an inner surface of the canister. Methods of manufacturing such a medical device are also disclosed.

Implantable medical device with relative motion control

Disclosed herein is an implantable medical device including a housing, a header, a connector port, and a collet assembly. The header can be arranged with the housing. The connector port can be arranged within the header and configured to couple an implantable lead to the header. The collet assembly can be arranged within the connector port and configured to frictionally engage a portion of the implantable lead and to secure the implantable lead with the header in response to insertion of the portion of the implantable lead into the connector port.

Automatic lead lock for an implantable medical device

An implantable medical device (IMD) is configured with a pressure sensor. The IMD includes a housing and a diaphragm that is exposed to the environment outside of the housing. The diaphragm is configured to transmit a pressure from the environment outside of the housing to a piezoelectric membrane. In response, the piezoelectric membrane generates a voltage and/or a current, which is representative of a pressure change applied to the housing diaphragm. In some cases, only changes in pressure over time are used, not absolute or gauge pressures.

Implantable medical device with pressure sensor

Various aspects of the present disclosure are directed toward apparatuses, systems and methods for connecting a lead to an implantable medical device. The apparatuses, systems and methods may include a clamp arranged within a connector port configured to secure the lead with a header in response to frictional engagement between a portion of the implantable lead and the clamp.

Lead retention method

Systems and methods to couple electrical contacts of a header of a medical device to respective feedthrough pins of a connector block of a medical device housing using a preformed wire are disclosed. The preformed wire can include a proximate portion comprising a number of turns shaped to engage a feedthrough pin. The number of turns of the preformed wire, once engaged with the feedthrough pin, can physically separate a major portion of the preformed wire from the connector block and the housing. The major portion of the preformed wire can be shaped to route a distal portion of the preformed wire to a first electrical contact of the header when the proximate portion of the preformed wire engages the feedthrough pin.

Preformed wire routes

A connector apparatus for a medical device includes a cylindrical core of nonconductive material, a beam of conductive material, and a sleeve of conductive material. The cylindrical core includes an outside surface, an inside surface, a hollow center having a cross sectional area, and a slot opening in the cylindrical core extending from the outside surface to the inside surface. The beam is placed in the slot opening in the cylindrical core, wherein the beam reduces the cross-sectional area of the hollow center of the cylindrical core. The sleeve of conductive material is placed over the outside surface of the cylindrical core.

Contact for a medical connector assembly

Implantable medical devices including interconnections having strain-relief structure. The interconnections can take the form of flexible circuits. Strain relief gaps and shapes are integrated in the interconnections to relieve forces in each of three dimensions. In some examples, the region of an interconnection which couples with a component of the implantable medical device is separated by a strain relief gap from a connection to a second component and/or a location where the flex bends around a corner.

Implantable medical devices with flexible interconnect having strain relief

A subcutaneous implantable cardioverter-defibrillator (S-ICD) comprising shocking electrodes configured to reduce the defibrillation threshold. The S-ICD may include a canister housing a source of electrical energy, a capacitor, and operational circuitry that senses heart rhythms and an electrode and lead assembly. The electrode and lead assembly may comprise a lead, at least one sensing electrode, and at least one shocking electrode. The at least one shocking electrode may extend over a length in the range of 50 to 110 millimeters and a width in the range of 1 to 40 millimeters.

Electrode designs in implantable defibrillator systems

An implantable medical device (IMD) includes a heterogeneous housing configured to receive and store one or more components of the IMD. The housing includes an intrinsically non-conductive and non-magnetic base material and at least one dopant with a property of at least one of electrical conductance and magnetic permeability. The base material and the dopant form a first region of the housing including a first skin depth and a second region of the housing including a second skin depth different than the first skin depth.

Housing for implantable medical device

An implantable medical device (IMD) with a receiving coil for wireless power transfer. The receiving coil may be disposed about a flux concentrator located in a housing of the IMD. The flux concentrator may concentrate non-radiative near-field energy through the receiving coil. In some cases, the near-field energy may be captured and converted into electrical energy that may be used to recharge a rechargeable power source of the IMD.

A medical system for providing a defibrillation therapy to a patient includes a cardiac monitoring device (CMD) configured to sense and record physiological data indicative of the patient's cardiac function. The CMD includes a communication component. The system also includes an external therapy device configured to deliver defibrillation therapy, and configured to be positioned external to and supported by the patient. The external therapy device includes an external therapy device communication component. The CMD communication component and the external therapy device communication component are configured to operatively couple the CMD and the external therapy device to one another, so as to work as a system to detect and treat fibrillation.
