First Claim
Patent Images
1. A support frame suitable for prosthetic implantable valves comprising:
- a proximal annular member longitudinally spaced from a distal annular member axially aligned with the proximal annular member around a longitudinal axis; and
a plurality of longitudinal connecting members extending substantially parallel to the longitudinal axis from the proximal annular member to the distal annular member and defining a hypothetical circumferential plane around an outer surface of the support frame and defining a lumen extending from a proximal end to a distal end of the support frame around the longitudinal axis;
the plurality of longitudinal connecting members including a first member opposably positioned across the lumen from a circumferentially adjacent second member, and a third member circumferentially adjacent to the first member.

Abstract
The disclosure relates to support frames for prosthetic implantable valves. The support frames may include a plurality of symmetrically arrayed interconnected U-shaped member structures. Preferred support frames are tubular structures enclosing a longitudinal axis and including a plurality of U-shaped member structures facing a distal or a proximal end of the support frame. Each U-shaped member structure may be connected to a single longitudinally adjacent U-shaped member facing in an opposite longitudinal direction, as well as two laterally adjacent U-shaped members.

19. A support frame suitable for prosthetic implantable valves comprising:
-
(a) a support frame having a proximal annular member longitudinally spaced from a distal annular member axially aligned with the proximal annular member around a longitudinal axis, and a plurality of paired longitudinal connecting members extending substantially parallel to the longitudinal axis from the proximal annular member to the distal annular member and defining a circumferential plane around an outer surface of the support frame and a tubular lumen around the longitudinal axis and extending from a proximal end to a distal end of the support frame; the plurality of paired longitudinal connecting members consisting of (n) pairs of closely spaced member pairs including a first closely-spaced member pair opposably positioned across the lumen from a circumferentially adjacent second closely spaced member pair, and (n−
2) pairs of closely spaced members circumferentially positioned between the first member pair and the second member pair, where (n) is an integer of 3 or more; and(b) a valve member attached to the support frame and moveable within the lumen to regulate fluid flow therein. - View Dependent Claims (20)
(c) the circumferential distance between each pair of closely spaced members is less than about 10% of the longitudinal length of the members; and (d) the valve member is attached to the first member and is moveable across the lumen between an open position permitting fluid flow through the lumen from the proximal end to the distal end, and a closed position substantially preventing fluid flow through the lumen, the valve member contacting the circumferential plane opposite the third closely spaced member pair in the closed position.

21. A method of treating a subject, the method comprising:
-
(a) loading an artificial valve prosthesis in a compressed configuration into a delivery catheter, the artificial valve prosthesis including (i) a support frame having a proximal annular member longitudinally spaced from a distal annular member axially aligned with the proximal annular member around a longitudinal axis, and a plurality of longitudinal connecting members extending substantially parallel to the longitudinal axis from the proximal annular member to the distal annular member and defining a circumferential plane around the outer surface of the support frame and a tubular lumen around the longitudinal axis and extending from a proximal end to a distal end of the support frame;
the plurality of longitudinal connecting members including a first member opposably positioned across the lumen from a circumferentially adjacent second member, and a third member circumferentially adjacent to the first member; and(ii) a valve leaflet attached to the support frame and moveable within the lumen to regulate fluid flow therein; (b) inserting the delivery catheter into a body vessel; (c) translating the delivery catheter to a treatment site; (d) deploying the artificial valve prosthesis by securably placing the artificial valve prosthesis in an expanded configuration at the treatment site to treat the subject; and (e) withdrawing the delivery catheter from the body vessel.
