Methods and Systems for Treating Cardiovascular Disease Using an Implantable Electroacupuncture Device

Abstract

An illustrative method of treating cardiovascular disease in a patient may include 1) generating, by an implantable stimulator, stimulation sessions, wherein the implantable stimulator comprises a central electrode of a first polarity centrally located on a first surface of a housing of the implantable stimulator and an annular electrode of a second polarity and that is spaced apart from the central electrode; and 2) applying, by the implantable stimulator, the stimulation sessions by way of the central electrode and the annular electrode to a location, within the patient, that is associated with the cardiovascular disease.

         6 . The method of  claim 1 , wherein the housing of the implantable stimulator is coin-sized and coin-shaped. 
     
     
         7 . The method of  claim 1 , wherein the annular electrode is located on the first surface of the housing. 
     
     
         8 . The method of  claim 1 , wherein the annular electrode comprises a ring electrode located around a perimeter edge of the housing. 
     
     
         9 . The method of  claim 1 , wherein the location comprises a median nerve of the patient. 
     
     
         10 . The method of  claim 1 , wherein the implantable stimulator is configured to be implanted at an acupoint PC6. 
     
     
         11 . An implantable stimulator for treating cardiovascular disease in a patient, comprising:
 a housing;   a central electrode of a first polarity and centrally located on a first surface of the housing;   an annular electrode of a second polarity and that surrounds the central electrode on the first surface of the housing, the annular electrode being spaced apart from the central electrode; and   pulse generation circuitry located within the housing, the pulse generation circuitry configured to apply stimulation sessions by way of the central electrode and the annular electrode to a location, within the patient, that is associated with the cardiovascular disease.   
     
     
         12 . The implantable stimulator of  claim 11 , further comprising a rechargeable battery within the housing and configured to provide power to the pulse generation circuitry. 
     
     
         13 . The implantable stimulator of  claim 12 , further comprising a receiver circuit within the housing and configured to receive, from an external controller, a power signal configured to recharge the rechargeable battery. 
     
     
         14 . The implantable stimulator of  claim 11 , further comprising a primary battery within the housing and configured to provide power to the pulse generation circuitry. 
     
     
         15 . The implantable stimulator of  claim 14 , wherein the primary battery has an internal impedance greater than 5 ohms. 
     
     
         16 . The implantable stimulator of  claim 11 , wherein the housing of the implantable stimulator is coin-sized and coin-shaped. 
     
     
         17 . The implantable stimulator of  claim 11 , wherein the annular electrode is located on the first surface of the housing. 
     
     
         18 . The implantable stimulator of  claim 11 , wherein the annular electrode comprises a ring electrode located around a perimeter edge of the housing. 
     
     
         19 . The implantable stimulator of  claim 11 , wherein the location comprises a median nerve of the patient. 
     
     
         20 . The implantable stimulator of  claim 11 , wherein the implantable stimulator is configured to be implanted at an acupoint PC6.
