Researchers in Stanford University's Biodesign Program have designed a novel implanted cardiac device (ICD) and method for delivering electrical cardiac therapy. This improved ICD and method are designed to reduced pain and negative cosmetic effects for patients and allow for selective replacement of the device.
The size, shape, and location of the ICD have been altered to make it less obtrusive for patients, thereby reducing the associated pain and cosmetic drawbacks of implantation. This invention alters the device implantation procedure to utilize a small incision such that the residual scar would be minimized. To improve defibrillation efficacy, the location of the device has been changed and the physical properties of the device have been enhanced (e.g. increasing flexibility and anti-thrombotic properties). The new design has separate housings for separate components, such as the battery, processor/circuitry, and capacitor, which allow selective replacement of its components.
