Room 133 Orbital Atherectomy and Calcified
Coronary Lesions Case presenter: Dr.
Study May Provide Conclusive Data on the Role of Calcified
NanoParticles in Heart Disease
1 December 2011 - Irish healthcare products and devices firm Covidien plc (NYSE:COV) said today it had obtained US Food and Drug Administration (FDA) approval for SpiderFX for the treatment of calcified
lesions used in conjunction with plaque excision in arteries of the lower body parts.
com) announced today that its patented ReValving System, consisting of a breakthrough 18-French-sized delivery catheter, was used to percutaneously implant its proprietary porcine pericardial tissue bioprostheses over the severely calcified
aortic heart valves of an 88-year-old female patient and a 77-year-old male patienteI|without the use of extracorporeal bypass, other cardiac assistance or even rapid pacing.
This video, for the first time, illustrates: 1) A decalcifying agent dissolving calcified
structures while the particles inside seem unaffected and are released to potentially begin the calcification process again.
One of the issues raised about CNPs is whether they are any different from calcified
crystals that are found in kidney stones and hardening of the arteries.

We have faced difficulties in delivering stents through tortuous and calcified
vessels to distal lesions," said Dr.
Defined as "the calcification of tissues other than bone and teeth," soft tissue calcification is the abnormal hardening or thickening of tissue into a bone-like material sometimes referred to as hard plaque, stones, or calcified
This further reduction in size is particularly important to the interventional cardiologist when accessing a diseased aortic valve via calcified
and tortuous vessels.
The patient had a particularly diseased and calcified
vessel that required a multi-device approach," said Dr.
This experience includes patients with diabetes, tortuous calcified
lesions, and small blood vessels.
