Pre-sized prosthetic chordae implantation system
View Patent ↗A system includes a pre-sized prosthetic chordae, a papillary penetration member, and a female securing member. The pre-sized prosthetic chordae is directly connected to an attachment member. The papillary penetration member extends through both the chordae and the attachment member. The female securing member receives the penetration member. The penetration member is an axis about which the chordae pivot.
1. A system comprising:
pre-sized prosthetic chordae directly connected to at least one attachment member;
a papillary penetration member extending through both the chordae and the at least one attachment member; and
a female securing member to receive the penetration member;
wherein the penetration member includes an axis;
wherein each of the chordae includes two elongated arms;
wherein the chordae are configured to extend radially from, and substantially orthogonal to, the axis when the penetration member penetrates a papillary muscle.
2. The system of claim 1 , wherein the penetration member includes a proximal end portion and a sharpened distal tip, the proximal end portion being directly connected to both the at least one attachment member and the chordae.
3. The system of claim 2 wherein the penetration member includes a needle.
4. The system of claim 1 , wherein each of the chordae includes a plurality of short arms, which (a) are shorter than the elongated arms, and generally orthogonal to the elongated arms, and (b) connect the elongated arms to one another.
5. The system of claim 1 , wherein the at least one attachment member includes a pledget.
6. The system of claim 5 , wherein the female securing member includes an additional pledget.
7. The system of claim 1 comprising a deployment apparatus comprising first and second jaws spaced from one another to accommodate a width of the papillary muscle and deploy the penetration member through the papillary muscle.
8. The system of claim 1 , wherein the at least one attachment member includes at least one of a rigid backing and a semi-rigid backing to support the penetration member.
9. The system of claim 1 , wherein the at least one attachment member includes a channel and the penetration member extends through the channel.
10. A system comprising:
prosthetic chordae;
at least one attachment member including a channel;
a female securing member; and
a papillary penetration member configured to pass through the channel, the chordae, and the securing member when implanted in a patient's heart;
wherein the penetration member: (a) includes an axis; and (b) is configured to extend substantially orthogonal to the chordae when implanted in the patient's heart.
11. The system of claim 10 , wherein the penetration member includes a proximal end and a sharpened distal tip.
12. The system of claim 11 wherein the penetration member includes a needle.
13. The system of claim 10 , wherein each of the chordae includes two elongated arms.
14. The system of claim 13 , wherein each of the chordae includes a plurality of short arms, which: (a) are shorter than the elongated arms, and generally orthogonal to the elongated arms, and (b) connect the elongated arms to one another.
15. The system of claim 10 , wherein the female securing member and the at least one attachment member each include a pledget.
16. The system of claim 10 comprising a deployment apparatus comprising first and second jaws spaced from one another to accommodate a width of papillary muscle and deploy the penetration member through the papillary muscle.
17. The system of claim 16 , wherein the penetration member is configured to pass from the first jaw and into the second jaw.
18. The system of claim 1 , wherein the female securing member includes a protective member to prevent a distal tip of the penetration member from damaging cardiac structures once the system is implanted in the patient's heart.
19. A system comprising:
prosthetic chordae;
at least one attachment member including a channel;
a female securing member; and
a papillary penetration member configured to pass through the channel, the chordae, and the securing member when implanted in a patient's heart;
wherein the penetration member includes an axis;
wherein each of the chordae includes two elongated arms and a plurality of short arms that: (a) are shorter than and generally orthogonal to the elongated arms, and (b) connect the elongated arms to one another.
20. The system of claim 19 wherein:
the penetration member includes a needle; and
the female securing member and the at least one attachment member each include a pledget.
