ROCKFORD, Ill. (CN) –  Self-proclaimed inventors filed suit, in pro per, alleging doctors and hospitals infringed a U.S. Patent for "Khan Hybrid Arteriovenous Shunt" by implanting the HeRO Graft device into patients.

Defendants include Hemosphere Inc., Cryolife Inc., Merit Medical Systems Inc., Kaiser Permanente, and "hospitals and doctors implanting unpatented HeRO graft," among others. The complaint lists pages of doctors and medical practices as defendants.
Plaintiffs Nazir Khan and Iftikhar Khan state in their lawsuit that "the claimed invention" is a "a hybrid arteriovenous shunt that serves as a conduit connecting an artery to the right atrium of the heart whereby the impure arterial blood flows continuously to the right atrium."
The Kahns allege defendants Hemosphere, Cryolife and Merit Medical "sold thousands of HeRO Graft devices" since 2008.
They seek a jury trial and more than $1 million in damages.
