Embodiment Construction

[0109] In this disclosure, the depiction of a given element or the use or consideration of a particular element number in a particular drawing or reference thereto in corresponding descriptive material may be contained in another drawing or descriptive material to which it relates The element, equivalent or similar element or element number identified in .

[0110] Throughout this disclosure, certain embodiments may be disclosed in a range format. It should be understood that the description in range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the disclosed scope. Accordingly, the description of a range should be considered as specifically disclosing all the possible subranges as well as individual values ​​within that range. For example, a description of a range from 1 to 6 should be considered to have specifically disclosed subranges, such as from 1 to 3, 1 to 4, 1 to 5, 2 to 4, 2 to 6, 3 to 6, etc., and in A sing...

Abstract

Systems and methods for applying the pulsed electromagnetic fields are provided. A system for applying a pulsed electromagnetic field (PEMF) to a cell, comprises: a sensor for obtaining a characteristic of the cell; a memory module having stored therein a plurality of characteristics and PEMF efficacy window data, each characteristic having its corresponding PEMF efficacy window data; a pulse generator coupled to a set of PEMF coils and configured to generate an output of electrical pulses to drive the set of PEMF coils; and a controller in communication with the sensor, the memory module andthe pulse generator, wherein the controller is configured to: retrieve, from the memory module, the PEMF efficacy window data that corresponds to the characteristic of the cell obtained by the sensor;and control the output of the pulse generator based on the retrieved PEMF efficacy window data such that the set of PEMF coils apply a PEMF in accordance with the PEMF efficacy window data.

Description

technical field [0001] The present disclosure relates to systems and methods for applying pulsed electromagnetic fields (PEMFs) to cells. Background technique [0002] Pulsed electromagnetic fields (PEMFs) have been shown to promote healing of skeletal bone nonunions and fractures that are otherwise resistant to traditional therapeutic modalities. Typically, PEMF generators are used to generate high magnetic flux penetration into hard and soft tissues to treat a variety of conditions including fractures and osteoporosis, resulting in the expected short healing and recovery times. PEMF waveforms usually consist of time-varying magnetic pulses with irregular and inhomogeneous signal parameters in the Hz range. However, this type of waveform does not effectively activate cells or tissues. [0003] Current systems and techniques for applying PEMF to a subject's tissue do not recognize, understand, or take into account the actual manner in which the target tissue responds to, a...
