An implantable medical device connector assembly and method of manufacture include a molded, insulative shell having an inner surface forming a connector bore, a circuit member including a one or more traces extending through the shell; one or more conductive members positioned along the connector bore and electrically coupled to the traces; and sealing members positioned between the conductive members.
摘要:
An electrical connector assembly for facilitating electrical connection between a medical lead and circuitry of an implantable medical device (IMD). The electrical connector assembly integrates a conductive element with an elastomeric seal in order to achieve a simplified structure for electrically coupling of a lead to circuitry of the IMD and also providing a hermetic seal, and facilitates simplified and improved electrical coupling of a medical lead to circuitry of the IMD.

Improvements in connector headers of implantable medical devices (IMDs) for making electrical and mechanical connections with a connector element of a proximal connector assembly of an electrical medical lead and components thereof are disclosed. A connector block disposed within a header body of the connector header has a threaded bore aligned with a header grommet aperture and a connector block bore aligned with a header connector bore. A penetrable grommet is disposed within the header grommet aperture, and a setscrew is threaded into the threaded bore having a setscrew socket disposed to be engaged by the tool inserted through the penetrable grommet within the header grommet aperture to enable rotation of the setscrew within the threaded bore to tighten the setscrew against or to loosen the setscrew from a lead connector element received in the header connector bore.
摘要:
An implantable medical device such as a defibrillator is described. The device includes an hermetically sealed housing containing a flat electrolytic capacitor and an energy source such as a battery. The battery is connected to the capacitor and provides charge thereto. The capacitor stores the charge at a relatively high voltage. The charge stored in the capacitor is discharged through a defibrillation lead to a site on or in the heart when fibrillation of the heart is detected by the implantable medical device. Methods of making and using the implantable medical device, the capacitor, and their various components are disclosed.
摘要:
A torque wrench for implantable medical devices is disclosed. The torque wrench comprises a first and a second component. The first component has first and second ends with a bore extending between the first and second ends of the first component. The first component includes a plurality of anti-rotation members extending from an inner surface of the bore at the second end of the first component. A second component includes a middle portion having a first and second ends. A drive shaft extends from the first end and a plurality of fingers extends from an exterior surface of the second end. The second component is received in the bore of the first component such that the fingers are interdigitate with the anti-rotation members.
摘要:
A battery having an electrode assembly located in a housing that efficiently utilizes the space available in many implantable medical devices is disclosed. The battery housing provides a cover and a shallow case a preferably planar, major bottom portion, an open top to receive the cover opposing the bottom portion, and a plurality of sides being radiused at intersections with each other and with the bottom to allow for the close abutting of other components located within the implantable device while also providing for efficient location of the battery within an arcuate edge of the device. The cover and the shallow case being substantially hermetically sealed by a laser weld technique and an insulator member disposed within the case to provide a barrier to incident laser radiation so that during welding radiation does not impinge upon radiation sensitive component(s) disposed within the case.
摘要:
This application discusses, among other things, a header assembly for coupling a medical electrical lead to a medical stimulating device including a header having a capture mechanism within a bore of a lead retention device. In an example, when the lead retention device is retracted from the bore, the capture mechanism prevents the device from falling out. In another example, the header assembly has a vent disposed within the bore of the lead retention device that permits unrestricted flow of air when the lead retention device is retracted from an engagement surface.
摘要:
A connector assembly of a medical electrical device includes a plurality of electrical contacts and an insulative base that supports the plurality of electrical contacts and extends between the plurality of electrical contacts and a housing of the device, and, wherein at least one contact of the plurality includes an elongate electrical coupling receptacle in which a first part of a feedthrough member extends, being fixedly coupled thereto. The feedthrough member further includes a second part and a bend, which is located between the first and second parts. The second part of the feedthrough member extends away from the contact and through a port formed in the insulative base adjacent to the contact.
