Abstract
Wireless implantable medical devices, in particular stents, for operably coupling to and functionally interfacing with tissue, such as vascular tissue, adjacent to the implantable medical device, having integrally formed electronic circuitry configured to sense and/or stimulate tissue, such as nerves, adjacent to or in proximity to the situs of the implantable medical device and capable of transmitting signals from the stent to a remote receiver to interrogate conditions in the body or receive signals to stimulate tissue.
Claims22
A wireless physiologically active implantable medical device, comprising a scaffold configured to be delivered to and implanted at a situs in a mammalian body, the scaffold further comprising a plurality of structural supports, at least one electronic circuit integrally formed as part of at least one structural support of the plurality of structural supports, at least one structural support of the plurality of structural supports further comprising at least one integrally formed region electrically coupling the at least one electronic circuit to tissue proximate the situs in a mammalian body.
A method of making a wireless physiologically active implantable medical device, comprising the steps of:
- a. Providing a substrate for forming the wireless physiologically active implantable medical device;
- b. Vacuum depositing a device forming material onto the substrate;
- c. Masking portions of the deposited device forming material to define recesses regions to be formed on the device forming material;
- d. Forming recesses in a surface of the device forming material;
- e. Depositing at least one electrical component layer of a plurality of electrical component layers into the recesses;
- and
- f. Forming surface features on a surface of at least some of the electrical component layers of the plurality of electrical component layers.
