The stimulator uses a power source/storage device, such as a rechargeable battery. Periodic recharging of such a battery is accomplished, for example, by inductive coupling with an external appliance. The stimulator provides means of stimulating a nerve(s) when desired, without the need for external appliances during the stimulation session. When necessary, external appliances are used for the transmission of data to and/or from the stimulator(s) and for the transmission of power. The system is capable of open- and closed-loop operation.Type: GrantFiled: January 24, 2006Date of Patent: February 15, 2011Assignee: Boston Scientific Neuromodulation CorporationInventors: Todd K Whitehurst, James P McGivern

Patent number: 7799037Abstract: A tool is provided for facilitating determining a proper location for an implantable device or medication, and for then delivering the implant to the precise location determined with the tool. To determine the target location, the tool may include a component for testing target locations, such as a stimulating probe for simulating a miniature implantable stimulator. In one embodiment, the tool is used to test a miniature implantable stimulator prior to depositing the implant precisely at the target location. The components of the tool are configured to maintain the implant at the target location while the tool is withdrawn. In one embodiment, a push rod assembly of the tool keeps the implant in position while it retracts the implant holder from around the implant. The ergonomic and light-weight tool leads to reduced surgical time, number and size of incisions, risk of infection, and likelihood of error.Type: GrantFiled: February 11, 2003Date of Patent: September 21, 2010Assignee: Boston Scientific Neuromodulation CorporationInventors: Tom X He, James P McGivern, Todd K Whitehurst
