Device And Method For Delivery Of Medical Devices To A Cardiac Valve

摘要

A catheter device for transvascular delivery of a medical device to a cardiac valve region of a patient comprises an elongate sheath with a first lumen, a distal end for positioning at a heart valve, a second lumen that extends parallel to or in the sheath, and an expandable embolic protection filter. The filter is arranged to extend from an orifice of the second lumen and, in the expanded, covers ostia of the side branch vessels in the aortic arch.

主权项

1. A method for transvascularly delivering a medical device to a cardiac valve of a patient, said method comprising:
introducing a catheter in a relaxed state into said vascular system, said catheter comprising an elongate sheath having a first lumen a second lumen that extends coaxially with said first lumen along a portion of said elongate sheath between a proximal end of said elongate sheath and a distal end of said elongate sheath; navigating said distal end of said elongate sheath through said vascular system to a site of said cardiac valve; covering ostia of the side branch vessels in the aortic arch by expanding an embolic protection unit from said second lumen and thereby stabilizing the distal portion of said catheter at the site of said cardiac valve; and delivering a medical device through the first lumen of said elongate sheath to said site of said heart valve while said embolic protection unit covers said ostia.
