The increasing refinement of minimally invasive surgical techniques and instrumentation - aided by the intraoperative visibility now afforded by transesophageal echocardiography and the introduction of lower-profile products such as the C-G Future band - is expected to rapidly increase this number.
The innovative C-G Future band restores proper "coaptation," or closure, of the mitral valve leaflets.
Bob Guezuraga, president of Medtronic Cardiac Surgery, said, "Today's introduction of the C-G Future band reinforces both Medtronic's commitment to providing a range of solutions for patients suffering from heart valve disease, as well as advancing the adoption of minimally invasive techniques in the surgical suite.
With the addition of the C-G Future band, Medtronic Cardiac Surgery offers the world's most complete array of products for valve replacement and repair.
The activity level will increase substantially as C-G approaches perihelion in August 2015.
The mission will spend an unprecedented amount of time close to C-G, studying how its activity turns on, how much of the surface is active or if that activity is primarily from discrete jets, how the nucleus interacts with the "collisional region" (the inner part of the coma where the gas density is high enough for collisions between atoms and molecules), and how all of that forms and drives the coma and tail.
But as in any dance, Rosetta will have to continuously adapt to its partner in order to have a successful, many-months tango with C-G.
