Valve Repair With Annuloplasty

Annuloplasty is used to restore an optimal orifice area and shape, provide support, and prevent further annular dilatation. Various techniques are used in mitral reconstruction. Developed in collaboration with the world's most experienced valve repair surgeons, our extensive portfolio of rigid, semi-rigid and flexible repair products gives you an opportunity to select a ring or band for each unique patient need.

Valve Replacement With Tissue Valves: Stented and Stentless

Medtronic's tissue valve expertise benefits from more than 40 years of experience, research, and skill, allowing us to provide the world with not only choice, but with advanced features that make a difference in patients' lives. Our third generation of tissue valve technology brings you AOA™ tissue treatment, the Physiologic Fixation process, and now, the Cinch™ Implant System – demonstrating our commitment to innovation.*

AOA Tissue Treatment

Age, calcium metabolism and glutaraldehyde pretreatment all contribute to the failure of tissue valves. AOA treatment is Medtronic's biochemical approach to mitigating calcification in the wall and leaflets of tissue valves. It is distinguished from other tissue treatments by its unique interaction and covalent bonding with the free aldehydes of glutaraldehyde.¹

Physiologic Fixation Process

Pressure fixation of valves can compromise the function and durability of the bioprosthesis.^1,2,3 The Physiologic Fixation process, used in Medtronic's third generation tissue valves, was developed to address the problem of structural valve deterioration caused by mechanical stress and is designed to maintain native collagen structure and porcine aortic root and leaflet geometry.

Cinch Advanced Implant System

The innovative, patented Cinch System, exclusively offered with the Mosaic^® and Hancock^®II aortic and mitral bioprostheses, draws the stent posts in to provide better visualization and more room for tying behind the stent posts. Suture knots slide easily down the surface of the device and into place. Release the system and the stent posts return to their original position.

Valve Replacement with Mechanical Valves

Medtronic Open Pivot™ mechanical heart valves bring something fundamentally different to bileaflet valve design. Unlike valves with a conventional cavity pivot hinge design, Medtronic Open Pivot valves have no recesses or cavities where potential thrombogenesis can occur.^4,5 In-vitro testing demonstrates that the Medtronic Open Pivot design reduces shear stress and turbulence through the pivot area.⁶ Clinical results show excellent thrombogenic and hemodynamic performance^7,8 and outstanding durability and implantability.^7-9 In addition, several patient studies show that Medtronic Open Pivot valves are remarkably quiet.¹⁰

Aortic Valved Graft

The Medtronic Open Pivot™ Aortic Valved Graft (AVG) unites the proven performance of the Open Pivot Heart Valve with leading graft technology for exceptional implantability. This valved conduit has no tapers or pleats, allowing for easy anastomosis anywhere on the graft.

Correction of Cardiac Anomalies of the Right Ventricular Outflow Tract (RVOT)

Current techniques and strategies for correction of cardiac anomalies of the RVOT include surgical repair and/or replacement of the pulmonary valve. These techniques include surgical implantation of bioprosthetic conduits or valves, or replacement via transcatheter technologies. A bioprosthetic conduit can consist of woven polyester tubes as supportive housing for glutaraldehyde-fixed porcine or bovine pericardial valves. Other surgeons prefer to implant a non-valved conduit or homograft, or to perform a valvuloplasty, thereby establishing a connection between systemic arteries and the pulmonary artery.
