Abstract
A PEMF contoured triangular transducer system (FIG. 1a-1b) used for PEMF therapy (such as after spinal fusion) uses a two-transducer configuration for generating flux-aided electromagnetic fields. The semi-rigid transducers (12, 14) are conformable to a selected anatomical contour, and incorporated with an adjustable belt (16) to provide bracing. The belt includes compartments for a drive electronics module (22), and a rechargeable battery pack (24), making the system portable. The drive electronics (FIG. 3) includes a PEMF processor (41) that executes a PEMF program for providing pulsing current to the front and back transducers at predetermined intervals, thereby activating the electromagnetic field according to a prescribed PEMF regimen.
Claims6
A triangular transducer system for providing electromagnetic therapeutic stimulation to a selected target area of a patient's body, comprising:
- a substantially triangular transducer including at least a primary winding with one selected number of turns to form a body having sufficient rigidity to maintain its desired shape, said transducer operable to be positioned proximate the target area;
- when flat, said transducer is substantially triangular to define three sides and three respective angular areas;
- said transducer being anatomically contoured to fit snugly adjacent the target area, with at least one of said sides being conformably curved such that corresponding angular areas are positioned on either side at the target area for electromagnetic therapy;
- and
- control electronics coupled to said primary winding for selectively generating electromagnetic fields, thereby implementing a prescribed electromagnetic therapy.
