Rechargeable medical implant system for sacral stimulation therapy
A recently filed patent (Publication Number: US20230302287A1) describes a rechargeable medical implant system for sacral stimulation therapy. The system includes an implantable neurostimulator device with a rechargeable power source, a pulse generator for generating non-ablative stimulation pulses, and an antenna assembly for wireless communication with an external charger device. The external charger device has a rechargeable battery, a wireless power transmitting unit, an outer housing with an on/off button and an indicator light, and an audio transducer for providing audio feedback during recharging.
The audio feedback includes a first audio alert to indicate alignment and coupling between the wireless transmitting unit and the wireless receiving unit, and a second audio alert to indicate that the neurostimulator device is fully charged. The first audio alert comprises a series of rising tones, while the second audio alert is different and also consists of rising tones. There is also a third alert during positioning the neurostimulator device before wireless coupling, which comprises repeating short beeps.
The portable charger device has a generally rounded shape with one flattened side to facilitate handling and positioning by the patient. It is designed to be held by a single hand of the patient for easy manual placement and positioning on the patient for recharging. The portable charger device has a planar underside for placement against the patient and a planar outer side that faces away from the patient during recharging. It also includes an indicator graphic on the planar underside to visually represent the target alignment of the portable charging device relative to the implanted neurostimulator device.
The system further includes a carrier device, such as a stretchable belt, to support the portable charger device while aligned with the implanted medical device during recharging. The carrier device has adjustable coupling features to allow the patient to adjust the belt to the mid-section of the patient for maintaining alignment during recharging.
Additionally, there is a recharging dock for the external portable charger device, which has a depression for receiving the portable charger device to facilitate wireless recharging. The depression in the recharging dock has a shape corresponding to the shape of the portable charger device.
Overall, this patent describes a rechargeable medical implant system for sacral stimulation therapy that includes an implantable neurostimulator device and an external portable charger device with various features to facilitate wireless recharging and provide audio feedback to the patient during the recharging process. The system aims to improve the convenience and ease of use for patients undergoing sacral stimulation therapy.
