A method of replacing a neurostimulator device. The method including explanting a previously implanted neurostimulator device from a site; operably coupling a replacement neurostimulator device to a previously implanted stimulation lead; and implanting a replacement neurostimulator device within the site, the replacement neurostimulator device having a volume of about ten cc's or less, and the previously implanted neurostimulator device having a volume of greater than about ten cc's.

Method of replacing an implanted neuromodulation device

An apparatus and method of electrically coupling a previously implanted stimulation lead with a replacement neurostimulator device. The apparatus and method configured to operably couple a proximal portion of a neuromodulation adaptor including a plurality of electrical conductors spaced apart at a first pitch spacing to a corresponding plurality of electrical terminals of a replacement neurostimulator device, and operably couple a distal end of the neuromodulation adaptor including a plurality of conductor elements and an electrically active set screw spaced part of a second pitch spacing to a corresponding plurality of electrical connectors of a previously implanted stimulation lead.

Adaptor

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.

Implantable pulse generator carrier used to interface with multiple lead sizes

Medical devices include a housing that defines both a lead bore and a compartment. A separate housing may be inserted into the compartment where the separate housing may include the electrical circuitry of the medical device such as circuitry that provides stimulation and/or sensing. Electrical conductors interconnect terminals of the separate housing to electrical connectors within the lead bore. The two housings may have different shapes and may be constructed of different materials. The housing that defines the lead bore and compartment may be shaped and sized for a specific implantation site while providing the compartment that is shaped and sized for the separate housing.
