Abstract
An assembly and method for end-to-side connection to anatomical tissue is disclosed. The system and method are particularly useful in coupling a ventricular assist device pump to an aorta. The assembly and method include using a tubular graft member coupled to a connection ring having at least one of a plurality of distally projecting tines extending from a distal aspect of the connection ring, and a stent having a distal flange section configured to abut an abluminal wall surface of the aorta, and an assembly including the tubular graft member and connection ring, for delivering the end-to-side connection.
Claims15
A tissue connection device, comprising an annular ring having a plurality of helically oriented tines, each of the plurality of helically oriented tines projecting axially and distally from a distal end of the annular ring, each of the plurality of tines are configured to penetrate directly into and be retained in anatomical tissue, and a plurality of axial projections extending from a proximal end of the annular ring, each of the axial projections being configured to removably couple to a delivery device and circumferentially rotate the annular ring to drive the plurality of helically oriented tines directly into the anatomical tissue, and a tubular graft member coupled to an inner circumference of the annular ring, wherein the plurality of helically oriented tines extend beyond and circumferentially surround a distal end of the tubular graft member.
A tissue connection device capable of being joined to anatomical tissue, comprising an annular ring having a plurality of tines helically projecting axially and distally from a distal end of the annular ring, a plurality of projections or a plurality of recesses in a proximal end of the annular ring configured to engage with an annular ring driver, and a tubular graft member affixed concentrically to an inner circumference of the annular ring, and having a distal end of the tubular graft member projecting axially and distally from the distal end of the annular ring such that the plurality of tines extend beyond and circumferentially surround the distal end of the tubular graft member, and the distal end of the tubular graft member is configured to engage with an inner surface of an opening in the anatomical tissue and the plurality of tines are configured to directly engage and embed into the anatomical tissue.
