FLAIL/PROLAPSE PREVENTING GUARD, METHODS OF USE AND KITS THEREOF
The present disclosure relates to a guard member for preventing prolapse, flail, or billow of at least one leaflet of a heart valve, and a pathology associated therewith. Specifically, the guard member is adapted, sized and configured to operably couple to the heart valve annulus and prevent a leaflet of the heart valve from extending cephalad to the heart valve's annular plane.
1 . A system for treating prolapse, flail, or billow of at least one leaflet of a native heart valve, the system comprising:
an annuloplasty ring configured for deployment using a delivery device, the annuloplasty ring comprising a plurality of anchors configured to be selectively deployed to secure the annuloplasty ring to a heart valve annulus of the native heart valve; and
a guard member comprising a plurality of struts coupled to a juncture at one end and coupled to the annuloplasty ring at another end, the guard member configured for deployment using the delivery device;
wherein a first strut and a second strut of the of plurality of struts together extend across the annuloplasty ring to prevent prolapse, flail, or billow of the at least one leaflet of the native heart valve.
2 . The system of claim 1 , further comprising a plurality of couplers, each coupler of the plurality of couplers coupled to a respective strut of the plurality of struts and configured to couple the respective strut to the annuloplasty ring.
3 . The system of claim 2 , wherein each coupler of the plurality of couplers is sized and configured to conform to a surface of the annuloplasty ring.
4 . The system of claim 3 , wherein the delivery device comprises a first delivery catheter configured to deliver the annuloplasty ring and a second delivery catheter configured to deliver the guard member.
5 . The system of claim 1 , wherein the juncture comprises a central strut.
6 . The system of claim 1 , wherein the juncture comprises an intersection forming a disc shape having a central aperture.
7 . The system of claim 6 , wherein the central aperture is configured to receive a coupling pin and the intersection is configured to engage the guard member with the delivery device via the coupling pin.
8 . The system of claim 1 , wherein the juncture comprises an intersection forming a disc shape.
9 . The system of claim 1 , wherein intersection is configured to be grasped by a plurality of graspers extending from the delivery device to engage the guard member with the delivery catheter.
10 . The system of claim 1 , wherein the guard member is configured to transition from a restrained position corresponding to a restrained shape to an unrestrained position corresponding to an unrestrained shape.
11 . The system of claim 10 , wherein each strut of the plurality of struts is configured to twist about a longitudinal axis of such strut.
12 . A method for treating prolapse, flail, or billow of at least one leaflet of a native heart valve, the method comprising:
causing a delivery device to deliver an annuloplasty ring at the native heart valve, the annuloplasty ring comprising at least one anchor;
causing the annuloplasty ring to deploy the at least one anchor to secure the annuloplasty ring to a heart valve annulus of the native heart valve;
causing the delivery device to deliver a guard member to the native guard valve, the guard valve comprising a plurality of struts coupled to a juncture at one end; and
causing the delivery device to couple the guard valve to a surface of the annuloplasty ring,
wherein a first strut and a second strut of the of plurality of struts together extend across the annuloplasty ring to prevent prolapse, flail, or billow of the at least one leaflet of the native heart valve.
13 . The method of claim 12 , wherein the guard member comprises a plurality of couplers, each coupler of the plurality of couplers coupled to a respective one the plurality of struts, and wherein causing the delivery device to couple the guard member to a surface of the annuloplasty ring comprises causing the couplers to couple to the annuloplasty ring.
14 . The method of claim 12 , wherein the delivery device comprises a first delivery catheter configured to deliver the annuloplasty ring and a second delivery catheter configured to deliver the guard member.
15 . The method of claim 12 , wherein the juncture comprises an intersection forming a disc shape having a central aperture.
16 . The method of claim 15 , wherein the central aperture is configured to receive a coupling pin and the intersection is configured to engage the guard member with the delivery device via the coupling pin.
17 . The method of claim 16 , further comprising causing the coupling pin to disengage the intersection to release the guard member from the delivery device.
18 . The method of claim 12 , wherein the juncture comprises an intersection forming a disc shape and wherein the intersection is configured to be grasped by a plurality of graspers extending from the delivery device to engage the guard member with the delivery device.
19 . The method of claim 18 , further comprising causing the plurality of graspers to disengage the intersection to release the guard member from the delivery device.
20 . The method of claim 12 , further comprising causing, prior to causing the delivery device to couple the guard valve, the guard member to transition from a restrained position corresponding to a restrained shape to an unrestrained position corresponding to an unrestrained shape different from the restrained shape.
