Latest updates on TMVI

CardiAQ™ Valve Technologies Reports First-in-Human Percutaneous Transfemoral, Transseptal Implantation with Its Second Generation Transcatheter Bioprosthetic Mitral Heart Valve Nearly 50% of patients suffering from a diseased mitral heart valve with severe, symptomatic regurgitation are currently denied open-heart surgery because it is considered too risky; in the future, percutaneous Transcatheter Mitral Valve Implantation (TMVI) may offer Continue Reading

PHARMASTAR :: new confirmation for bio-absorbable stents

07 June 2012 Bioabsorbable polymer and drug eluting stents can reduce the risk of thrombosis intrastent to 4 years in patients undergoing coronary angioplasty primary. These results come from an analysis recently published on European Heart Journal. Data of individual patients from three randomised clinical trials, multicenter and large-scale (ISAR-TEST 3, ISAR-TEST 4, and LEADERS), Continue Reading

They are small tubes inserted into coronary arteries during transcutaneous angioplasty intervention  and some of them are able to elute drugs into vessel lumen wall to prevent restenosis. Coronary angioplasty has revolutionised the treatment of coronary atherosclerotic disease since its appearance in the mid 70. The introduction of coronary stenting has represented an important step Continue Reading

Left Ventricular Assist Device: LVAD

VAD is the acronym of Ventricular Assist Device and consists of an implantable pulsatile pump powered with rechargeable batteries that provides to impress to the blood physiological pressure and the flow in a patient whose heart , affected for example by dilated cardiomyopathy , is no longer able to pump adequate amounts of blood. In Continue Reading

Valvola a membrana “jellyfish”

In figura è rappresentata una valvola a membrana in gomma siliconica che ho sviluppato in collaborazione e per conto di una società biomedica italiana. La valvola fu costruita utilizzando un supporto in materiale polimerico ad alta resistenza (PEEK). Si è lavorato a controllo numerico un disco di partenza per ricavare all’interno della struttura dei raggi Continue Reading

Elettrodo per elettroerosione cerniera

Quello mostrato in figura è un elettrodo in grafite da finitura di superfici con elettroerosione ottenuto per avvicinamento di due cilindri lavorati con facce piane (parallele agli assi principali dei cilindri stessi) e successivamente lavorati con macchina a C.N. e controllati al 100% con adatte apparecchiature di misura e controllo dimensionale .Per lavorare completamente una Continue Reading

Bileaflet valve – virtual pivots

The figure aside shows a ring with a spark eroded(EDM) virtual pivot proper to accommodate two leaflet in ceramic material having the function of cardiac valve with low hemolysis and high biocompatibility. EDM technology was proved perfectly suitable to the removal of small quantities of titanium with great precision and reproducibility of results. Each ring Continue Reading
