  • Patent number: 12004939
    Abstract: A transcatheter growth device for treating congenital illnesses in infantile and other pediatric heart disease patients and methods for making and using the same. The growth device includes an elongated device frame with alternating annular growth cell members and spacing members that axially span proximal and distal end regions of the device frame. The growth cell members and spacing members define a radial periphery for the growth device. Each growth cell member can comprise a scaffolded growth cell member with first and second annular strut arrangements coupled via a growth cell junction to provide device frame flexibility. A retention member for engaging a selected lumen within a patient and a covering member for sealing the growth device, when deployed, are disposed at the device periphery. The growth device advantageously can be deployed for treating heart disease alone or in combination with one or more additional growth devices.

  • Patent number: 11944540
    Abstract: Described herein are devices and methods for mitral valve repair. The devices and methods implant a plurality of distal anchors at an annulus of the mitral valve (e.g., the posterior annulus) and tension artificial chordae to pull the portion of the annulus toward an opposite edge and inward into the ventricle. This can effectively reduce the size of the orifice and increase coaptation. The delivery devices can be configured to be actuated to form a distal anchor made of a pre-formed knot. The delivery devices deliver the pre-formed knot in an elongate configuration. Actuation of the delivery device causes the pre-formed knot to transition from the elongate configuration to the deployed configuration by approximating opposite ends of a suture coupled to a coiled configuration to form one or more loops. After formation of the knot, the delivery device can be withdrawn.

  • Patent number: 11925552
    Abstract: A stent device with skirt folds and a processing method thereof, a skirt folding method, and a heart valve. The stent device comprises a stent (1, 105) and a flexible skirt (2, 107), the skirt (2, 107) having an expanded state, in which the skirt is axially extended and surrounds the stent (1, 105) before release thereof, and a folded state, in which the skirt is driven by the deformation caused when the stent (1, 105) is released, collapses and folds axially along the released stent (1, 105) so as to form an annular peripheral leakage-blocking portion. The peripheral leakage prevention technology enables an interventional stent to fit to the inner wall of a vessel more snugly, such that the stent does not easily move and is more stable, thereby being suitable for more people, reducing additional risks of surgery and preventing complications such as peripheral leakage and thrombus.
