Abstract

The disclosure pertains to an apparatus for maintaining patency within vessels in the vicinity of surgical procedures which might otherwise be compressed and partially or totally occluded, and methodsof use therefor.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to US Provisional Application Serial No. 62 / 361,655, filed July 13, 2016, the entire contents of which are incorporated herein by reference. Background technique [0003] During surgical interventions, especially within the heart, the necessary insertion and manipulation of instruments and prostheses may exert pressure on adjacent structures which may result in temporary partial or Complete blockage and consequent risk of tissue damage. [0004] For example, during transcatheter positioning of a replacement aortic valve, displacement of the native valve, and / or expansion of components of the replacement valve, pressure may inadvertently be applied to adjacent heart wall tissue and thereby to the blood vessels associated with that tissue. put pressure on. In the case of aortic valve replacement, pressure can be delivered to the left anterior descending artery (LAD) of the...
