Embodiments herein relate to medical devices including electric field shaping leads and methods for using the same to treat cancerous tumors within a bodily tissue. In an embodiment, an implantable lead for a cancer treatment system is disclosed. The lead can include a lead body having a proximal end and a distal end, where the lead body can define a lumen. The lead can also include a paddle disposed at the distal end of the lead body, the paddle having a width that is greater than a width of the lead body. The paddle can include one or more electrodes disposed on the paddle and one or more electrical conductors disposed within the lumen of the lead body to provide electrical communication between the one or more electrodes and the proximal end of the lead body. Other embodiments are also included herein.

Electric field shaping leads for treatment of cancer

An implantable medical device may include each of a conductive canister, a printed circuit board assembly (PCBA), and a header. A feedthrough and ferrule couple the interior of the canister, where the PCBA is, to one or more elements contained in the header such as an antenna and/or a port for coupling to a lead. The ferrule may be directly attached to the conductive canister and the electronic circuit board. The electronic circuit board carries an RF transmitter for telemetry purposes, and has an RF ground plane layer therein. The ferrule is capacitively coupled to the RF ground plane the PCBA, and has a size and/or shape relative to the RF ground plane that provides sufficient capacitance to offer an improved RF ground plane path to the conductive canister at a desired telemetry frequency.

Implantable medical device with feedthrough antenna ground structure

A leadless pacing device may include a housing having a proximal end and a distal end, and one or more electrodes supported by the housing. The housing may include a body portion and a header. A distal extension may extend distally from the header of the housing, the distal extension including one or more electrodes. The header may include a guide wire port and a guide wire lumen may extend from the guide wire port through the header of the housing and through the distal extension. A fixation member may extend from the header of the housing. The header may be formed from an over mold process.

Systems and methods for treating cardiac arrhythmias

Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include a proximal section including a deflection mechanism for deflecting the proximal section, and a distal holding section extending distally of a distal end of the proximal section and defining a cavity therein for receiving an implantable leadless pacing device. The distal holding section may be structured to have portions that flex and bend while allowing the implantable device to be recaptured within the distal holding section.

Delivery devices and methods for leadless cardiac devices

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

Implantable leadless pacing devices and medical device systems including an implantable leadless pacing device are disclosed. An example implantable leadless pacing device may include a pacing capsule. The pacing capsule may include a housing. The housing may have a proximal region and a distal region. A first electrode may be disposed along the distal region. One or more anchoring members may be coupled to the distal region. The anchoring members may each include a region with a compound curve.

Leadless cardiac pacing devices

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

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 device for the active fixation of an implantable medical lead includes a housing, a tine assembly, and rotatable shaft. The housing includes a proximal end for connecting to the lead and a distal end opposite the proximal end. The housing defines a housing lumen having a longitudinal axis extending between the proximal end and the distal end. The tine assembly is disposed within the housing lumen. The tine assembly includes at least one tine configured to self-bias from a linear configuration within the housing to a curved configuration outside of the housing. The rotatable shaft extends through the housing lumen. The shaft is configured to engage the tine assembly such that rotation of the shaft transitions the at least one tine between the linear configuration and the curved configuration.

Stimulation/sensing electrode fixation device and electrical lead

A leadless pacing device may include a housing having a proximal end and a distal end, and a set of one or more electrodes supported by the housing. The housing may include a first portion and a second portion, with a guide wire port extending through the second portion. A guide wire lumen may extend through the second portion of the housing and the guide wire port may be located at a proximal end of the guide wire lumen. An exposed electrode may be located on a side of the housing that is opposite a side on which the guide wire port is located. The leadless pacing device may include a fixing member on the housing and extending radially from the housing. The leadless pacing device may further include a proximal member extending proximally from a proximal end of the housing. The proximal member may be elongated.

A capacitively loaded loop antenna for an implantable medical device is disclosed comprising a feed extending from a conductive surface of an implantable housing, a radiating element having a cross section larger than the feed, and a return coupling the radiating element to a conductive surface of the implantable housing. The radiating element can have a height above the top surface of the implantable housing, creating a capacitance between the radiating element and the conductive surface of the implantable housing configured to counteract the inductance of the capacitively loaded loop antenna.
