Biodegradable prosthesis
A tympanic membrane prosthesis includes a tubular body having a lumen extending therethrough and open at each of a proximal and distal end. The tubular body forms a structurally self-supporting, body compatible, and body absorbable device. The device is formed of a composite structure that includes an inner portion having an inside surface and an outer portion having an outside surface. The inside surface forms at least a portion of the lumen extending through the tubular body. The inside surface is adapted to provide less resistance to fluid flow than the outside surface. The outside surface is adapted to produce an inflammatory reaction in adjacent tissue at a tympanic membrane. The device is adapted for insertion into an opening through the tympanic membrane for placement with the proximal end and the distal end disposed on opposite sides of the tympanic membrane.
TUBULAR MESH SUPPORT DEVICE WITH DIFFERENT CIRCUMFERENTIAL AREAS
The invention relates to a mesh support device (10; 20) for supporting a breast implant (30), wherein the mesh support device (10; 20) is tubular and comprises a first circumferential mesh area (11; 21), which is characterized by a first set of mesh characteristics and which has a first circumferential length, and a second circumferential mesh area (12; 22), which is characterized by a second set of mesh characteristics and which has a second circumferential length, the first set of mesh characteristics being different from the second set of mesh characteristics. The invention relates also to a breast implant device comprising the breast implant (30) and the mesh support device (10; 20).
Kirigami modification of biomedical tissue reinforcing meshes and matrices for expansile two-to-three dimensional conversion
Provided are intraoperative devices, the devices comprising a substrate having a plurality of discontinuous cuts formed therein, the plurality of discontinuous cuts being formed such that when the substrate is subjected to deformation, the substrate is capable of deformation beyond an initial state so as to achieve a first shaped three-dimensional state. Through design of the cut patterns in 2D, one can locally control the stretchability and elasticity within the substrate. The substrate can then be deformed into a 3D structure that can provide shape and support to reconstructed tissue in the desired regions while also minimizing operative time and cost. Also provided are related methods of using the disclosed devices; the devices can be used in autologous tissue donation procedures as well as prosthetic procedures.
Artificial vascular graft
The invention relates to an artificial vascular graft comprising a primary scaffold structure encompassing an inner space of the artificial vascular graft, said primary scaffold structure having an inner surface facing towards said inner space and an outer surface facing away from said inner space, a coating on said inner surface, wherein a plurality of grooves is comprised in said coating of said inner surface. The primary scaffold structure comprises further a coating on said outer surface. The primary scaffold structure and the coating on said inner surface and on said outer surface are d designed in such a way that cells, in particular progenitor cells, can migrate from the periphery of said artificial vascular graft through said outer surface of said coating, said primary scaffold structure and said inner surface to said inner space, if the artificial vascular graft is used as intended. The invention relates further to a method for providing said graft.
TISSUE REPAIR IMPLANTS AND METHODS FOR MAKING AND USING SAME
One aspect of the present disclosure relates to a tissue repair implant comprising a first layer of extracellular matrix and a second support layer of biocompatible material securely attached to the first layer at one or more fixation points. At least one of the fixation points comprises a first projection that is associated with the first layer and securely attached, via a fixation mechanism, to the second support layer.
Methods of using a self-adjusting stent assembly and kits including same
A method of using a self-adjusting stent assembly includes estimating body lumen diameter(s) associated with a portion of a body lumen in which a stent assembly will be placed; determining, based on the estimated diameter(s), target expanded stent diameter(s) of the stent assembly which is to be placed in the portion of the body lumen; selecting the stent assembly for stenting the portion of the body lumen, wherein the stent assembly is configured to: expand from an initial to expanded diameters within a range of expanded diameters; wherein the range of expanded diameters is from about 9 mm to about 5.5 mm; and wherein the target expanded stent diameter(s) is/are within the range of expanded diameters; and apply a chronic radial force to a wall that forms the portion of the lumen, wherein the radial force is less than about 0.33 N/mm; and implanting the stent assembly in the portion of the body lumen.
TENDON REPAIR IMPLANT AND METHOD OF IMPLANTATION
A tendon repair implant for treatment of a complete or partial thickness tear in the supraspinatus tendon of the shoulder is provided. The implant may incorporate features of rapid deployment and fixation by arthroscopic means that compliment current procedures; tensile properties that result in desired sharing of anatomical load between the implant and native tendon during rehabilitation; selected porosity and longitudinal pathways for tissue in-growth; sufficient cyclic straining of the implant in the longitudinal direction to promote remodeling of new tissue to tendon-like tissue; and, may include a bioresorbable construction to provide transfer of additional load to new tendon-like tissue and native tendon over time.
RESORBABLE MACROPOROUS BIOACTIVE GLASS SCAFFOLD AND METHOD OF MANUFACTURE
A method of manufacturing a resorbable, macroporous bioactive glass scaffold comprising approximately 15-45% CaO, 30-70% SiO.sub.2, 0-25% Na.sub.2O, 0-17% P.sub.2O.sub.5, 0-10% MgO and 0-5% CaF.sub.2 by mass percent, produced by mixing with pore forming agents and specified heat treatments.
Surgical implant
A surgical implant (10) comprises an areal, flexible, porous basic structure (12) having a first face and a second face. At least one resorbable dyed film piece (20) is attached to the basic structure (12) and comprises a plurality of solid protrusions emerging from the dyed film piece (20) in a direction away from the basic structure (12). The at least one dyed film piece (20) is arranged in a shape structure which is asymmetric (“E”) in the area of the basic structure (12). Optionally, the implant (10) further comprises an adhesion barrier sheet (16).
Calcium Phosphate Polymer Composite and Method
A bone-repair composite includes a core and a sheath. The core is a first primary unit including a combination of a first set of yarns coated with a calcium phosphate mineral layer. The first set of yarns being made from a first group of one or more polymers. The sheath is a second primary unit a combination of a second set of yarns or one or more polymer coatings. The second set of yarns being made from a second group of one or more polymers, wherein the composite is made by covering the core with the sheath, and the composite is compression molded to allow the sheath to bond to the core. The bone-repair composite has a bending modulus comparable to that of a mammalian bone, such that the ratio of the core to the sheath is provided to maximize the mechanical strength of the bone-repair composite to mimic the mammalian bone.
