A method of forming a medical device contact element includes annealing an elongated rod of Ti-15Mo alloy material to form an annealed rod having a Young's Modulus of less than 13.5 Mpsi and an elastic range or strain of at least 0.7%. Then forming a contact ring element from the annealed rod and assembling the contact ring element into a medical device. Contact rings and lead receptacles including the same are also described.

Devices, systems, and methods for crimping a medical device are disclosed. More specifically, the present disclosure relates to devices, systems, and methods for reducing the diameter of a collapsible heart valve prosthesis to be loaded onto a delivery device. The devices, systems, and methods using at least one funnel to crimp the heart valve prosthesis and load it onto the delivery system.

Devices and methods for crimping a medical device

Implantable medical devices have modular lead bores that are constructed from individual lead bore modules. A given modular lead bore utilizes the number of individual lead bore modules necessary for the particular implantable medical device. Each lead bore module has a lead bore passageway and a feedthrough passageway. An electrical contact is present within the lead bore passageway of each lead bore module and the electrical contact is aligned to the lead bore passageway of a lead bore module. Hermetic feedthrough assemblies are also present within the lead bore passageway of each lead bore module. A feedthrough pin passes through a hermetic feedthrough assembly within a feedthrough passageway of each lead bore module. Each feedthrough pin is electrically coupled to a corresponding electrical contact and the medical device circuitry.

Seals used within lead bores of implantable medical devices for creating a seal to implantable medical leads inserted into the lead bores include a cylinder that engages the lead body. The length of contact of the cylinder to the lead body is at least 0.010&#x2033; long while average contact pressure is no greater than (10 pounds per inch)/(contact length). Adequate electrical isolation is achieved, even when a debris particle is present between the inner cylinder and the lead body while insertion force remains acceptable.

Seals for lead bores of implantable medical devices

A method of forming a medical device lead connection element is described. The method includes positioning an end portion of a lead filar to overlap a lead end connection element such that the positioning creates mutual interference between the lead filar and the lead end connection element, and forming an interference configuration. Then melting the end portion of the lead filar to form a weld joint and allowint the end portion of the lead filar to move towards the end connection element.

Medical device lead connection assembly

Implantable medical devices that include a battery to power circuitry utilize a battery connector to electrically interconnect the battery to the circuitry. The battery connector may be mounted directly to a device housing to have the battery connector a fixed position within the device. Battery terminals of the battery are electrically connected to terminals on the battery connector, and the terminals on the battery connector are electrically connected to power terminals of the circuitry. The battery connector may include various features such as mounting grooves formed in a connector body, tapered pins to connect to power terminals on a circuit board, as well as plates to engage the battery terminals. The device housing may provide mounting features that allow the battery connector to be affixed directly to the device housing.

A method of manufacturing a hermetic lead connector includes fixing an electrically insulating ring between an electrically conducting contact ring and an electrically conducting spacer ring to form a hermetic ring subassembly, and fixing a plurality of the hermetic ring subassemblies in axial alignment to form a hermetic lead connector. The hermetic lead connector includes an open end, an outer surface, and an inner surface defining a lead aperture. The hermetic lead connector provides a hermetic seal between the outer surface and the inner surface.

Methods of manufacturing a hermetic lead connector

Seals used within lead bores of implantable medical devices for creating a seal to implantable medical leads inserted into the lead bores include an inner cylinder that engages the lead body. The inner cylinder is surrounded by a gap to either an outer cylinder of the seal or to surrounding structures of the implantable medical device. The inner cylinder has freedom of movement within the gap such that movement of the lead body that is off-axis relative to a centerline of the lead bore causes movement of the inner cylinder that is providing the seal. In this manner, the seal engagement to the lead body is maintained during this off-axis movement of the lead body.

The disclosure is directed to a pressure sensor of an implantable medical device. The pressure sensor may utilize detect fluid pressure based on a changing capacitance between two capacitive elements. The pressure sensor may define at least a portion of a fluid enclosure of the IMD. In one example, the pressure sensor has a self-aligning housing shape that occludes an opening in the pump bulkhead of the IMD. An operative surface of the pressure and the portion of the fluid enclosure may be formed of a corrosion resistant and/or biocompatible material. A first capacitive element of the pressure sensor may be a metal alloy diaphragm that deflects in response to external fluid pressure. A second capacitive element of the pressure sensor may be a metal coating on a rigid insulator sealed from the fluid by the diaphragm and a housing of the sensor.
