Systems and methods for implantable medical devices and headers are described. In an example, an implantable medical device includes a device container including an electronic module within the device container. A modular header core includes a first core module including a first bore hole portion of a first bore hole, the first bore hole portion configured to couple a first electrical component with the electronic module. A second core module includes a second bore hole portion of a second bore hole different than the first bore hole, the second bore hole portion configured to couple a second electrical component with the electronic module. The first core module is detachably engaged with the second core module. A header shell is disposed around the modular header core and attached to the device container.

Implantable device header and method

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

An electrical connector for detachably connecting an electrical lead to an implantable medical device includes a conductive housing and a plurality of spring contacts. The conductive housing extends from a proximal end to a distal end. The conductive housing has an interior surface forming a hollow cylinder. The plurality of spring contacts projects from the interior surface of the conductive housing and toward the proximal end. The plurality of spring contacts is at least partially contained within the conductive housing and configured to form an electrical connection to an electrical lead inserted within the conductive housing. The conductive housing and the plurality of spring contacts are integrally formed by an additive manufacturing process such that the electrical connector is a unitary structure.

Electrical connector and method for manufacturing an electrical connector

An implantable pulse generator includes a device housing containing pulse generator circuitry and a header molded to the device housing. The header can be formed of an epoxy header material. A header component can have a first part molded in the header material to fix the header component to the header at a surface of the header and a second part extending out of the header material.

Method of molding a header of an implantable pulse generator

Systems and methods for implantable medical devices and headers are described. In an example, an implantable medical device includes a device container including an electronic module within the device container. A modular header core includes a header core module including at least one bore hole configured to receive a lead, an antenna attachment module coupled to the header core, and an antenna engaged with the antenna attachment module. The antenna attachment module is configured to locate the antenna in a selected position with respect to the header core module.

A method of preparing an electrode for use with an implantable medical device, the electrode including a titanium surface, the method including: maintaining a nitrogen gas environment proximate to the titanium surface, delivering energy to a portion of the titanium surface, modifying the portion of the titanium surface with the energy delivered to the titanium surface, and forming titanium nitride by reacting titanium at the portion of the titanium surface with nitrogen from the nitrogen gas environment. Modifying includes increasing a surface area of the portion of the titanium surface, and removing titanium from the portion of the titanium surface. The titanium nitride is formed at the portion of the titanium surface where titanium has been removed.

Laser generated surface finishes for implantable medical devices and electrodes

In general, techniques are described for labeling an implantable medical device (IMD). In one example, an IMD can include a housing including electronic circuitry. The IMD can include a header coupled to the housing and includes a core. The core can define a bore and include a first metal label positioned adjacent to the at least one bore. The IMD includes a lead assembly including at least one lead having a distal end and a proximal end, the at least one lead including a second metal label, the distal end including at least one electrode and the proximal end received within the bore.

An electrode for use with an implantable medical device includes a titanium surface, and a titanium nitride layer formed on at least a portion of the titanium surface. At least some titanium of the portion of the titanium surface is removed from the titanium surface prior to forming the titanium nitride layer. The textured titanium nitride layer is formed by reacting nitrogen proximate to the portion of the titanium surface with titanium at the portion of the titanium surface.

An implantable pulse generator includes a core assembly, a seal plug, and an outer layer overmolded over the core assembly adjacent the seal plug. The core assembly defines a core hole extending through the core assembly from a core interior to a core outer surface. The core hole has a hole outer portion and a hole inner portion. A first diameter of the hole outer portion is less than a second diameter of the hole inner portion. The seal plug is positioned in the core hole and has a plug outer portion aligned with the hole outer portion and a plug inner portion aligned with the hole inner portion. A third diameter of the plug outer portion is less than a fourth diameter of the plug inner portion. The outer layer leaves a top of the seal plug exposed.

Seal plug

A method includes providing a mold defining a mold cavity for receiving material to be molded into a molded part, positioning an insert at least partially in the mold such that a portion of the insert defines a portion of the mold cavity, and injecting the material into the mold cavity to substantially fill the mold cavity to form the molded part. The molded par can then be removed from the mold and the insert can be removed from the molded part. The mold can include silicone and the insert can include polyoxymethylene.
