Title: Innovator Robert Ian Lister: Advancements in Heart Valve Technology

Introduction: Robert Ian Lister, based in Sunnyvale, CA, is an accomplished inventor recognized for his significant contributions to medical technology. With a portfolio of four patents, Lister has established himself as a prominent figure in the field of heart valve innovations.

Latest Patents: Lister's most recent patent focuses on a heart valve holder and method for resisting suture looping. This innovative device offers an improved technique for implanting a tissue-type prosthetic mitral heart valve, effectively preventing suture looping and providing the ability to constrict the commissure posts of the valve. The design incorporates an upstanding or shaft member, which is axially positioned to ensure that attachment sutures extend beyond the commissure post tips. This mechanism creates a tent-like structure that prevents any looping of pre-implanted sutures during valve deployment. Furthermore, the shaft member is designed to be axially movable, allowing it to be retracted initially and then actuated right before deployment. Notches on the distal tip of the shaft capture attachment sutures to ensure secure engagement. The flexibility of the material used for the sutures is engineered to cover the commissure post tips, enhancing the prevention of suture looping.
