A heart valve prosthesis includes a support element of a tubular structure, and at least two lobule bodies connected to the inner wall of the support element, wherein the support element comprises an outer layer fabric having selvages on opposite sides, and a suture line for fixing the other two sides of the outer layer fabric to each other to form the tubular structure; each of the lobule bodies is formed by stacking at least one lobule layer; and the opposite sides of the lobule body are respectively an interwoven side and a free side, with the interwoven side being fixed between the two selvages of the outer layer fabric by means of weaving, and the free side being a selvage. An artificial valve formed by same, and a preparation method therefor are also disclosed.

A method of implanting a prosthetic mitral heart valve includes advancing a guidewire through a femoral vein, an atrial septum, and a native mitral valve. A guide catheter is advanced over the guidewire and a delivery catheter is advanced through the guide catheter. A mitral valve assembly is disposed along a distal end of the delivery catheter. The mitral valve assembly includes a stent and a valve having three leaflets. The stent has a flared inlet end, an outlet end, and an intermediate portion with a plurality of prongs disposed along its outer surface. The mitral valve assembly is deployed with the flared inlet end positioned in a left atrium and the intermediate portion positioned between native mitral valve leaflets. The prongs penetrate surrounding tissue for preventing upward migration of the mitral valve assembly and the flared inlet end is shaped for preventing downward migration.

A replacement heart valve prosthesis for transcatheter repair of a native valve, the replacement heart valve comprises a valve construct mounted to the exterior surface of an expandable frame. The frame comprises an expandable region near the distal end of the frame, and a cusp region near the proximal region comprising a plurality of valve attachment features. The valve construct may be attached to the valve construct at least at the valve attachment features. The replacement heart valve prosthesis of present disclosure may be a more durable and long-lasting valve that has added benefits by placing valve tissue between the expandable frame and native cardiac tissue.

A method of treating infection and/or inflammation in a subject includes steps of providing a polyester biomaterial comprising diol monomers and at least first carboxylate monomers, wherein the first carboxylate monomers are itaconate; and administering the polyester biomaterial to the subject. The polyester biomaterial can be in the form of a biomimetic, and characterized by hydrolytic degradability. The polyester biomaterial may further include second carboxylate monomers. The biomaterial can be poly(itaconate-co-citrate-co-octanediol).

Heart valve implants and methods for implanting and delivering same are described. A heart valve implant can include a shaft, having a first end and a second end, an anchor, and a plurality of wafers. The anchor is coupled to the first end of the shaft and configured to secure the heart implant to a patient's heart. The wafers are coupled to the second end of the shaft and configured to form a stacked array of wafers. The stacked array of wafers can partially reduce a flow of blood through a heart valve upon coming in contact with a portion of a leaflet of the heart valve.

The invention relates to a device for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation enhancement element for implantation across the valve; a system including the coaptation enhancement element and anchors for implantation; a system including the coaptation enhancement element, catheter and driver; and a method for transcatheter implantation of a coaptation element across a heart valve.

The present invention provides devices for treating functional mitral regurgitation and methods of use thereof. The devices translocate a subject's mitral valve in an apical direction. The devices thereby treat mitral regurgitation while preserving a subject's original mitral valve and chordae tendinae.

Compositions of the invention for regenerating defective or absent myocardium comprise an emulsified or injectable extracellular matrix composition. The composition may also include an extracellular matrix scaffold component of any formulation, and further include added cells, proteins, or other components to optimize the regenerative process and restore cardiac function.

The invention relates to a method for producing a storable molded body made of bacterial cellulose and a molded body produced according to the method. A preferred method includes providing a molded body made of bacterial cellulose. Optionally, mechanically pressing the entire molded body or parts of the molded body at temperatures in the range of 10° C. to 100° C. and pressures in the range of 0.01 to 1 MPa for a pressing time of 10-200 min. Treating the molded body with a solution of 20% by weight to 50% by weight of glycerol and 50% by weight to 80% by weight of a C1-C3-alcohol/water mixture. Drying the treated molded body.

An implant for the cardiovascular system is provided, the implant is insertable into an organ and includes a body structure configured to be disposed inside an organ; and an electret coating disposed on the body structure; wherein the electret coating includes a negative charge such that a negative electrostatic field is formed in proximity of the body structure, the charge is such that the negative electrostatic field corresponds to a positive electrostatic field formed by a damaged tissue of the organ.
