Mitral heart valve storage and handling system

An improved holder and storage system for a tissue-type prosthetic mitral heart valve that constricts the commissure posts of the valve and prevents suture looping. A rod axially movable relative to the holder tensions lengths of attachment sutures that extend between the commissure post tips to create a tent and flex the tips inward, thus helping to prevent looping of any of an array of pre-implanted sutures around the leading tips during delivery of the valve. The holder has a safety mechanism that prevents valve delivery before the rod is deployed. One embodiment automatically deploys the rod upon opening a storage jar. One embodiment permits a delivery handle to directly deploy the rod, while another uses a separate worm screw and coupling. A holder clip that attaches to a packaging sleeve may be formed of flexible members meshed together from which the heart valve and holder are easily pulled free to eliminate a step of decoupling the clip from the sleeve.

Detection of bioprosthetic valve degeneration

The invention relates to a method for predicting or diagnosing a risk of bioprosthetic valve degeneration. Further, the invention relates to a medical device, in particular a bioprosthetic valve coated with EPCR less prone to degeneration and/or calcification once implanted.

Prosthetic heart valve having notched leaflet

A prosthetic heart valve provided herein can include at least one leaflet having a body portion and two opposite sleeve portions. The body portion can be defined by at least two side edges adjacent each sleeve portion. The at least one leaflet can define at least one notch between at least one of the two side edges and the adjacent sleeve portion, or at least one aperture positioned adjacent at least one side edge and an adjacent sleeve portion.

Device and method for mitral valve regurgitation treatment

A mitral valve replacement device is adapted to be deployed at a mitral valve position in a human heart. The device has an atrial flange defining an atrial end of the device, a ventricular portion defining a ventricular end of the device, the ventricular portion having a height ranging between 2 mm to 15 mm, and an annulus support that is positioned between the atrial flange and the ventricular portion. The annulus support includes a ring of anchors extending radially therefrom, with an annular clipping space defined between the atrial flange and the ring of anchors. A plurality of leaflet holders positioned at the atrial end of the atrial flange, and a plurality of valve leaflets secured to the leaflet holders, and positioned inside the atrial flange at a location above the native annulus.

Medical device using bioabsorbable material

Bioabsorbable medical devices such as vascular closures, mitral chorea replacements, and mitral leaflet extensions are provided.

Fully-transseptal apical pad with pulley for tensioning
11678980 · 2023-06-20 · ·

An apical pad for securing a prosthetic heart valve within a native valve annulus. The apical pad includes a first collar, a second collar and plurality of struts extending between the first collar and the second collar. The plurality of struts has a delivery condition in which the plurality of struts collectively form a first cross-section and a deployed condition in which the plurality of struts collectively form a second cross-section greater than the first cross-section. The apical pad may be coupled to a tether extending from a prosthetic heart valve and may transition from the delivery condition to the deployed condition by tensioning the tether.

TRANSCATHETER VALVE DELIVERY SYSTEM WITH SEPTUM HOLE CLOSURE TIP ASSEMBLY
20170348096 · 2017-12-07 ·

Transcatheter heart valve delivery systems having a tip assembly configured to close the hole or perforation made in a patient's septal wall after transseptal delivery of a stented prosthetic heart valve to a defective heart valve (e.g., a mitral valve). The delivery device is configured to permit in vivo release of the tip assembly immediately after deployment of the stented prosthetic heart valve to implant the tip assembly into the septal wall proximate the hole through which the stented prosthetic heart valve is delivered. Methods of treating the defective heart valve, including closing the hole made during transseptal delivery of the stented prosthetic heart valve with the tip assembly of the delivery device are also disclosed.

METHODS FOR MANUFACTURING RESILIENT PROSTHETIC SURGICAL HEART VALVES

Disclosed prosthetic valves can comprise a sewing ring configured to secure the valve to an implantation site. Some disclosed valves comprise a resiliently collapsible frame having a neutral configuration and a collapsed deployment configuration. Some disclosed frames can self-expand to the neutral configuration when released from the collapsed deployment configuration. Collapsing a disclosed valve can provide convenient access to the sewing ring, such as for securing the valve to the implantation site, as well as for the insertion of the valve through relatively small surgical incisions.

ASSEMBLY FOR A CLOSURE DEVICE WHICH IS IMPLANTABLE IN THE SUPERIOR OR INFERIOR VENA CAVA OF A HUMAN BODY IN A MINIMALLY INVASIVE MANNER, AND TRICUSPID VALVE PROSTHESIS WHICH IS IMPLANTABLE IN A MINIMALLY INVASIVE MANNER
20230181315 · 2023-06-15 · ·

A minimally-invasive implantable closing device (1) in the superior or inferior vena cava of a human body, with a valve device (6) and an anchoring device (7). The valve device (6) has closing elements and a support structure. The closing elements extend flat over a respective joint surface and in each case can be moved between a closed position, in which the closing elements together close a valve opening, and an open position, in which a flow is released through the valve opening. Further, a minimally-invasive implantable tricuspid valve prosthesis is provided.

Percutaneous valve deployment
09833314 · 2017-12-05 · ·

A polymeric heart valve is disclosed including: a valve body having a central axis having a body fluid pathway extending along the central axis from an inflow end to an outflow end; a flexible stent disposed about an outer circumference of the body and including at least three flexible stent posts each extending in the axial direction to a tip; and at least three flexible leaflets extending from the stent, each of the leaflets having an attached edge defining an attachment curve along the stent extending between a respective pair of stent posts.
