Masters HP™ Mechanical Heart Valve Standard Cuff

Product Highlights

  • Sewing cuff redesigned to facilitate supra-annular placement, allowing for an increase in orifice size for a given tissue annulus diameter
  • Increased effective orifice area (EOA), lower pressure gradients, and improved performance1-5
  • 85 degree leaflet opening angle offers improved laminar flow and reduces turbulence1,2,6
  • Controlled torque rotation mechanism allows for easy rotation and intraoperative adjustment
  • The FlexCuff™ is flanged and more pliable than the standard cuff
  • St. Jude Medical heart valves are MR conditional7

Rx Only

St. Jude Medical prosthetic heart valves are indicated for use as replacement valves in patients with a diseased, damaged, or malfunctioning native or prosthetic valve. Possible side effects for all valvular implants include, but are not limited to: regurgitation, thromboembolic phenomena, resistance to flow, infection, hemolysis, dysrhythmias, and prosthetic dehiscence or failure. Anticoagulation is recommended for patients with mechanical valve implants. Please see the physician’s manual for a full description of indications, contraindications, side effects, precautions, warnings and instructions for use.
