Filed:

May 14, 2004

Appl. No.:

10/540968

Inventors:

Wei Sun - Cherry Hill NJ, US
Jae Hyun Nam - Broomall PA, US
Andrew Leete Darling - Philadelphia PA, US
Saif Khalil - King of Prussia PA, US

Assignee:

Drexel University - Philadelphia PA

International Classification:

G06G 7/48

US Classification:

703 11

Abstract:

A process and apparatus are provided for manufacturing complex parts and devices which utilize a CAD environment to design a part or device to be created (FIG. ); Boolean, scaling, smoothing, mirroring, or other operations to modify the CAD design; a software interface to convert the CAD designed part (Data Process System) or device into a heterogeneous material and multi-part assembly model (Design Input Model) which can be used for multi-nozzle printing; and a multi-nozzle system to print the designed part or device using different, specialized nozzles (Tissue substitutes).

International Classification:

G06Q 30/02

H02J 50/12

Abstract:

A wireless charger system for inductively charging a rechargeable battery of an implantable pulse generator (IPG) implanted in a human body is provided. A charging coil in the charger is wirelessly coupled to a receiving coil of the IPG to charge the rechargeable battery. An end-of-charge (EOC) circuit continuously monitors the reflected impedance from a reflected impedance sensor and determines the end of charge when a predetermined pattern of the reflected impedance corresponding to an EOC signal from the IPG is received.Advantageously, receiving the EOC signal through the charging coil eliminates the need to provide a separate communication circuit in the IPG that communicates with the charger.

Saif Khalil - Wayne PA, US

International Classification:

A61N 1/36
A61N 1/378
A61N 1/05
A61N 1/02

Abstract:

An implantable pulse generator (IPG) that generates spinal cord stimulation signals for a human body has a programmable signal generator that can generate the signals based on stored signal parameters without any intervention from a processor that controls the overall operation of the IPG. While the signal generator is generating the signals the processor can be in a standby mode to substantially save battery power.

Christopher Biele - King of Prussia PA, US
Saif Khalil - Wayne PA, US
Jason Highsmith - Charleston SC, US

International Classification:

A61N 1/372
A61N 1/05
A61N 1/36

Abstract:

Systems, devices and methods for providing neuromodulation are provided. One such system can include an implantable pulse generator. The implantable pulse generator can include a circuit board having a microcontroller that generates signals that are input into an ASIC. The ASIC serves as pulse generator that allows electrical pulses to be outputted into leads. The implantable pulse generator is capable of receiving and/or generating signals either via a wireless communication (e.g., a wireless remote control), a touching force (e.g., pressure from a finger), a motion sensor or any combination of the above.

Abstract:

A wireless charger for automatically tuning an optimum frequency to inductively charge a rechargeable battery of an implantable pulse generator (IPG) that generates spinal cord stimulation signals for a human body is provided. The charging coil in the charger is wirelessly coupled to a receiving coil of the IPG to charge the rechargeable battery. An optimization circuit detects a reflected impedance of the charging coil through a reflected impedance sensor, and select an optimum frequency of a charging signal supplied to the charging coil based on the detected reflected impedances of a plurality of charging frequencies in a selected frequency range. Advantageously, the optimum charging frequency provides a more efficient way to charge the IPG's rechargeable battery.
