RF diathermy and faradic muscle stimulation treatment
View Patent ↗An RF diathermy coil assembly, including a generally elastically deformable patient conforming garment and a conductive coil secured to the garment. The conductive coil having a woven wire construction such that the coil can deform as the garment elastically deforms. The RF diathermy coil assembly can be used for wound healing in conjunction with muscle stimulation.
1. An RF diathermy coil assembly, comprising:
a patient-conforming garment;
a primary coil, including a plurality of windings, the primary coil being connectable to a power source lead and being incorporated into the patient-conforming garment;
a secondary coil including a plurality of windings, the secondary coil being disposed proximate the primary coil and being incorporated into the patient-conforming garment, at least one of the primary coil and secondary coil establishing an RF field, wherein at least one of the patient-conforming garment, the primary coil and the secondary coil, define a passage for receiving a body part therein; and
a tuner, coupled to at least the secondary coil for tuning the RF field to the resonant frequency of the body part disposed within the passage for receiving the body part therein, wherein the primary coil, the secondary coil, or both further comprise a non-conductive elastic deformable core.
2. The RF diathermy coil assembly in accordance with claim 1 , wherein the elastic core includes a plurality of polymer strands which can form elastically.
3. An RF diathermy coil assembly, comprising:
a patient-conforming garment;
a primary coil, including a plurality of windings, the primary coil being connectable to a power source lead and being incorporated into the patient-conforming garment;
a secondary coil including a plurality of windings, the secondary coil being disposed proximate the primary coil and being incorporated into the patient-conforming garment, at least one of the primary coil and secondary coil establishing an RF field, wherein at least one of the patient-conforming garment, the primary coil and the secondary coil, define a passage for receiving a body part therein; and
a tuner, coupled to at least the secondary coil for tuning the RF field to the resonant frequency of the body part disposed within the passage for receiving the body part therein, wherein the primary coil, the secondary coil, or both have a woven wire construction such that the RF diathermy coil can be deformed as the garment elastically deforms and further comprises a non-conductive elastically deformable sheath over the woven wire.
4. The RF diathermy coil assembly in accordance with claim 3 , wherein the non-conductive sheath includes a woven fabric.
5. An RF diathermy coil assembly, comprising:
a patient-conforming garment defining a passage for receiving a body part therein;
a primary coil including a plurality of windings disposed around the passage, the primary coil being connectable to a power source lead and being incorporated into the patient-conforming garment, the primary coil responsive to RF power delivered via the power source lead for establishing an RF field;
a secondary coil including a plurality of windings disposed around the passage, the secondary coil being disposed proximate the primary coil and being incorporated into the patient-conforming garment;
a tuner coupled to the secondary coil for tuning the RF field to a resonant frequency of the body part disposed within the passage; and
a housing releasably connectable to the primary coil and the secondary coil, wherein the tuner is disposed within the housing.
6. The RF diathermy coil assembly in accordance with claim 5 , further comprising a woven RF shield connected to the garment, wherein the shield is disposed toward the exterior of the garment relative to the majority of the length of the RF diathermy coil.
7. The RF diathermy coil assembly in accordance with claim 5 , wherein the garment includes a polymer foam.
8. The RF diathermy coil assembly in accordance with claim 5 , further including a balun connected to the primary coil.
9. The RF diathermy coil assembly in accordance with claim 5 , wherein the tuner includes a tuning capacitor.
10. The RF diathermy coil assembly in accordance with claim 5 , wherein the secondary coil includes more windings than the primary coil.
11. The RF diathermy coil assembly in accordance with claim 5 , wherein the housing is releasably connected to the patient-conforming garment.
12. The RF diathermy coil assembly in accordance with claim 5 , wherein the patient-conforming garment is elastically deformable to conform to the body part insertable in the passage.
