implants examines transmitter optimization for wirelessly powering a small implant embedded in tissue. The design of a Wireless Power Transfer (WPT) system based on magnetic resonant coupling, in which the secondary is located inside the body of the human connected to a battery recharge system of an active implantable medical device. Since Wireless Power transfer technology (WPT) gains its popularity in broad range of applications like medical implant systems such as wireless capsule endoscopy. The scope of the project is to implement the Wireless Power Transmission technology for charging pacemakers which is implemented in heart of human body reduces the complexity of the patient. It also minimizes the healthy and safety risk factors and cost as there is no use of transmitting wires. This technology reduces the complexity of the system and makes the system portable.

The heart is a highly efficient pump with four chambers. The two chambers on the right side of the heart receive oxygen-poor (‘blue’) blood from the body and pump this blood to the lungs, where it receives oxygen. The oxygen-rich (‘red’) blood returns to the left side of the heart, and the two left chambers pump this oxygenated blood to the rest of the body. The lower (major) pumping chamber, called the ventricles, receive blood from the top chambers, the atria, and do the hard work of pumping the blood to the other parts of the body. In a normal heart, the atria contract (squeeze) first, pushing blood into the ventricles. The ventricles then contracts, pumping the blood out to the lungs and the rest of the body. This process repeats at a regular rate, usually around60 to 100 times every minute.

1. INTRODUCTION
The development of Implantable medical devices for sensing the malfunction of internal organs, local stimulation and delivery of drug has played a major role in modern medicine. These devices helps patient to manage a broad range of medical disorders through preventive and post-surgery monitoring. These types of devices depend on Batteries for their DC power for effective function and needs replacement of batteries in due course time. The wireless delivery of power transfer to the batteries has reduced the risks associated with battery replacement and enable miniaturization of the implant. This project deals with the implementation of wireless power transfer especially in case of pacemaker device used in heart problems.

Structure and Function of Heart
In a normal functioning heart, the pumping action is synchronized by the sino atrial (SA) node or sinus node, which sends the controls the rate of heart by sending electrical signals which makes the contraction and expansion of heart.
