Dr. Adams co-invented the ring, which was cleared by the Food and Drug Administration last month, with Alain F. Carpentier, MD PhD, Chairman Emeritus of Cardiovascular Surgery at the Hôptial Europeen Georges Pompidou in Paris.
"We have learned a lot since Professor Carpentier invented the original Physio ring, and we are optimistic that the changes we made in the Physio II ring will result in a higher quality of valve repair in patients suffering from mitral valve disease," said Dr. Adams.
The mitral valve lies between the left atrium and left ventricle of the heart. It prevents blood from leaking back into the left atrium during ejection (systole). Mitral valve regurgitation occurs when the valve does not close completely, and today the preferred treatment for such a condition is to repair the valve apparatus as opposed to replacing the valve with a metal or animal valve. Annuloplasty rings are specially designed to help restore the mitral valve to its normal size and shape (the valve is often enlarged or distorted in a diseased state.) If left untreated, mitral valve regurgitation can lead to debilitating symptoms including cardiac arrhythmia, congestive heart failure, and irreversible heart damage.
The new Carpentier-Edwards Physio II ring has many unique capabilities for mitral valve repair patients. "We can now use this ring to match the exact measurements and characteristics of a patient's mitral valve like never before," said Dr. Adams. The ring also features a sewing cuff that makes the device easier to implant.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
