Scientists Create the World's Smallest Pacemaker

Scientists have developed smallest pacemaker, smaller than a grain of rice. This tiny device helps control the heartbeat and can dissolve in the body when no longer needed. The innovation, reported by AFP, marks a major advancement in medical technology.

When Will It Be Tested on Humans?

The world’s smallest pacemaker is not ready for human trials yet. According to John Rogers, a lead researcher from Northwestern University, testing on humans could start within the next two to three years. Experts believe this wireless pacemaker could transform heart treatments.

Why Is This Innovation Important?

Millions of people worldwide rely on permanent pacemakers to regulate their heartbeats. However, traditional pacemakers need surgical removal when no longer required. This new wireless pacemaker can naturally dissolve in the body, eliminating the need for additional surgeries.

How Will It Help Patients?

The pacemaker is designed to help:

  • Adults recovering from heart surgery by restoring normal heartbeats.
  • Children with congenital heart problems, providing temporary heart support.

A Surgery-Free Future for Heart Patients

Unlike traditional pacemakers, the new device does not require wires or repeated surgeries. Since it dissolves in the body when its job is done, patients can avoid unnecessary procedures. This groundbreaking innovation could change heart treatments forever.
