METHODS AND DEVICES FOR DELIVERY OF A PROSTHETIC VALVE
A valve prosthesis and a system for delivering a valve prosthesis are described herein. The system can include a support frame, a valve anchor comprising an anchoring leg and a plurality of U-shaped members, and a connection member coupled to the support frame and slidably coupled to the anchoring leg.
1 . A method of assembly for valve prosthesis delivery, the method comprising:
coupling a plurality of sutures to an end of a support frame;
looping the plurality of sutures to a plurality of anchoring legs of a valve anchor so that the plurality of sutures is slidable along the plurality of anchoring legs, wherein each of the anchoring legs is interconnected between a pair of U-shaped members of the valve anchor, and wherein each of the plurality of sutures are looped in a respective longitudinal slot extending along a length of the respective anchoring leg;
compacting the support frame and the valve anchor; and
housing the compacted valve anchor and the compacted support frame slidably coupled to the compacted valve anchor within an outer sheath.
2 . The method of claim 1 , further comprising arranging the compacted valve anchor and the compacted support frame serially within the outer sheath.
3 . The method of claim 1 , further comprising inserting a plurality of pins of a pin assembly through a plurality of connection apertures of the plurality of anchoring legs to radially constrain an end of each of the anchoring legs.
4 . The method of claim 3 , further comprising sliding the plurality of pins through the plurality of connection apertures and through a plurality of lock apertures.
5 . The method of claim 3 , further comprising positioning the end of each of the anchoring legs between a first flange and a second flange.
6 . A method of assembly for valve prosthesis delivery, the method comprising:
coupling at least one suture to a support frame; and
looping the at least one suture to an anchoring leg of a valve anchor so that the at least one suture is slidable along the anchoring leg.
7 . The method of claim 6 , further comprising:
compacting the support frame and the valve anchor; and
housing the compacted support frame and the compacted valve anchor within a sheath with the support frame coupled to the valve anchor via the at least one suture.
8 . The method of claim 6 , further comprising inserting a pin through a connection aperture of the anchoring leg to constrain a portion of the anchoring leg.
9 . The method of claim 8 , further comprising sliding the pin through the connection aperture and through a lock aperture.
10 . The method of claim 8 , further comprising further comprising positioning the portion of the anchoring leg between a first flange and a second flange.
11 . A method of assembly for a valve prosthesis delivery, the method comprising:
housing a valve prosthesis in a compacted state within a sheath of a delivery system, the valve prosthesis comprising a valve anchor and a support frame coupled to the valve anchor, the valve anchor comprising a plurality of anchoring legs having a plurality of connection apertures;
slidably coupling a pin assembly around a core member so that the pin assembly is slidable longitudinally along the core member; and
inserting a plurality of pins of the pin assembly through the plurality of connection apertures of the valve anchor and a plurality of lock apertures of the delivery system to engage the plurality of anchoring legs of the valve anchor.
12 . The method of claim 11 , further comprising positioning the plurality of connection apertures of the valve anchor between a first flange and a second flange, wherein the lock apertures of the delivery system extend through both the first flange and the second flange.
13 . The method of claim 11 , further comprising positioning an annular component of the pin assembly within a cavity of the delivery system so that the pin assembly is reciprocal within the cavity between an engaged configuration and a disengaged configuration, wherein the plurality of pins extends longitudinally from the annular component.
14 . The method of claim 11 , further comprising slidably coupling a pusher component around the core member so that the pusher component is slidable longitudinally along the core member.
15 . The method of claim 14 , further comprising positioning a tubular component of the pin assembly to extend along the core member towards the pusher component so that the pusher component can contact an end of the tubular component.
16 . The method of claim 14 , further comprising positioning a tubular component of the pusher component to extend along the core member towards the pin assembly so that the tubular component can contact the pin assembly.
17 . The method of claim 14 , further comprising positioning the pusher component at a first end of the support frame so that the first end of the support frame can contact the pusher component.
18 . The method of claim 17 , further comprising positioning a pushing block at a second end of the support frame opposite to the first end of the support frame so that the second end can contact the support frame.
19 . The method of claim 11 , further comprising coupling the valve anchor to the support frame via at least one suture slidably coupled along a plurality of longitudinal slots extending along a length of the plurality of anchoring legs.
20 . The method of claim 11 , further comprising positioning the valve anchor and the support frame coupled to the valve anchor serially within the sheath.
