56. Title: Spherical tri-leaflet heart valve

Inventors: Kamal Krishna Kar, Nirmal Kumar Gupta, Mridul Bharadwaj, Meraj Ahmed, 

Malay Kumar Das, Krishnamurthy Muralidhar and  Sutapa Mondal

Application number: 201711043075, Date: November 30, 2017

Abstract: A tri-leaflet heart valve comprising an annular housing, three triangular protrusions formed on the inner surface of the annular housing, three spherical leaflets, three struts formed on the inner surface of the annular housing ring, positioned between the triangular protrusions, to ensure proper resting and sealing of the leaflets during reverse flow of blood, a spherical strut formed on each flat surface of the three protrusions  to control the angular movement of the leaflets during flow of blood. Each leaflet has a protrusion on either lateral surface, and is mounted to a mounting cavity formed on two triangular protrusions on either side, for being freely rotatable within the annular housing. The mounting cavity is closer to the inner surface of the annular housing ring, to ensure sufficient movement of the leaflet at very low forward pressure gradient.
