The present invention relates to a deformable body formed of at least 20% by volume of a polymer material in which individual polymer backbones have a plurality of functional groups capable of cross-linking to form a cross-link; said polymer material provided in a first less-cross- linked configuration; wherein said polymer material, upon application of a suitable stimuli, said stimuli causes cross-linking of said functional groups to form cross-linking between said polymer backbones such that said polymer material is in a second more-crosslinked configuration.

An annuloplasty ring prosthesis comprising a frame having an outer surface; and a cover surrounding the frame. The cover comprises a bioprosthetic tissue that can be regenerative or fixed and non-regenerative. The frame can be bioabsorbable or non-degradable. A ring prosthesis and a method of manufacturing a ring prosthesis is also provided. The ring prosthesis comprising an elongated rod member formed into a substantially ring shape, the elongated rod member being formed substantially from a flat bioprosthetic tissue.

Compositions and methods for filling tissue voids and defects with a self-assembling biopolymer configured to form a shape-retaining matrix are described.

The present disclosure relates to a bone graft composition, and more particularly, to a bone graft composition including hydroxypropyl methylcellulose and a preparation method therefor. Moreover, the present disclosure relates to a bone graft composition that has an optimal composition ratio at which the dissolution rate of hydroxypropyl methylcellulose is excellent. In addition, the present disclosure relates to a bone graft composition containing hydroxypropyl methylcellulose in an amount that provides shape retainability, and a preparation method therefor. More specifically, the present disclosure relates to a bone graft composition containing hydroxypropyl methylcellulose in an amount that provides an optimum osmotic pressure and shape retainability, and a preparation method therefor.

A bone graft substitute which combines substantially the high mechanical stability of spherical porous granules without the limitation of reduced intergranular space, and a method for manufacturing the bone graft substitute. In an exemplary embodiment of the invention, the surface of the granules comprises indentations that increases the porosity within the implanted mass significantly and thus provides more space between the granules for tissue ingrowth. The indentations on the granules cause them to have an irregular shape and thus an increase in the intergranular space is achieved, while mechanical stability is maintained. An exemplary method according to the invention includes the steps of manufacturing the granules; mixing the granules with a porogen; pressing the porogen into the surface of at least a portion of the granules; and removing the porogen from the implant mass to form the indentations in the surface where the porogen was pressed into the granules.

Soft tissue grafts, packaged soft tissue grafts, and methods of making and using soft tissue grafts are disclosed. One soft tissue graft includes processed tissue material having first and second opposed surfaces. The first and second opposed surfaces are bounded by first and second edges. The first edge has a concave shape that curves toward the second edge. The second edge has a convex shape that curves away from the first edge. The first surface comprises a plurality of apertures. At least one of the apertures is formed from a multi-directional separation in the first surface. One method of making a soft tissue graft includes positioning a cutting die on a surface of tissue material, pressing the cutting die into the tissue material to cut the tissue material, and processing the cut tissue material to create processed tissue material.

A medical textile product includes a textile substrate having opposed first and second surfaces with the textile substrate including a textile construction of one or more yarns. The second surface includes a coating of a substantially water-insoluble, non-porous elastomeric sealant. The one or more yarns at the first surface are pre-treated with a removable composition, such that the water-insoluble elastomeric sealant encapsulates a portion of fibers of the one or more yarns at the second surface of the textile substrate. The textile substrate is substantially impermeable to fluid. The first surface is substantially free of the substantially water-insoluble elastomeric sealant. The textile substrate may be a non-tubular substrate, such as a planar sheet, a shaped sheet, and a tape, or a tubular substrate, such as a cylindrical conduit, a tubular conduit, a Y-shaped, a T-shaped conduit, a multi-channel conduit, and a bulbous shaped conduit.

An implantable textile graft includes a textile tubular wall of liquid permeable textile construction of one or more yarns having opposed inner and outer surfaces. A portion of the inner surface includes a removable coating. The outer surface includes a coating of a water-insoluble, non-porous elastomeric sealant, such as a silicone-containing polymer, a polyurethane-containing polymer, and/or a polycarbonate-containing polymer, for limiting movement of fluid through the wall. The textile tubular wall is, after curing of the sealant, impermeable to water at 120 mm Hg pressure. The removable coating prevents migrating of the outer coating onto the inner surface of the textile tubular wall and the removable coating is removed prior to implantation of the graft. The portion of the inner surface of the textile tubular wall is substantially free of the water-insoluble elastomeric sealant following removal of the removable coating.

A method of detecting the presence or absence of a sealant applied to a textile graft includes the steps of: providing a textile graft having a first surface and an opposed second surface; providing a water soluble masking agent; applying the water soluble masking agent to at least a portion of the first surface of the textile graft; providing a sealant solution; providing a visual indicator; applying the water insoluble sealing agent and the visual indicator to the second surface of the textile graft; and removing the water soluble masking agent after the step of applying sealing solution. The second surface has visual indication of the visual indicator and the first surface is substantially free of visual indication of the visual indicator. An implantable textile graft includes the selectively applied visual indicator.

A bone graft substitute which combines substantially the high mechanical stability of spherical porous granules without the limitation of reduced intergranular space. The granules have a high porosity whilst maintaining high stability, and can be pushed into a defect without risking significant breakage of the granules and, simultaneously, bone cells can grow into the space between the granules. In an exemplary embodiment of the invention, the surface of the granules comprises indentations, when viewed from the exterior of the granules. An indentation increases the porosity within the implanted mass significantly and thus provides more space between the granules for tissue ingrowth. Due to the indentations on the granules, the granules have an irregular shape and thus an increase in the intergranular space is achieved, while mechanical stability is maintained. A biocompatible polymer, such as a polypeptide, is disposed about at least some of the granules to form a coating thereon.
