IMPLANTABLE MEDICAL DEVICE WITH THERMOPLASTIC COMPOSITE BODY AND METHOD FOR FORMING THERMOPLASTIC COMPOSITE BODY
An implantable medical device is disclosed comprising a thermoplastic composite body having anterior, first lateral, second lateral, posterior, superior, and inferior surfaces, and at least one dense portion and at least one porous portion which are integrally formed. The at least one dense portion is formed of a first thermoplastic polymer matrix that is essentially non-porous, and which is continuous through a thickness dimension from the superior surface to the inferior surface. The at least one porous portion is formed of a porous thermoplastic polymer scaffold having a second thermoplastic polymer matrix which is continuous through the thickness dimension. A method for forming the thermoplastic composite body is disclosed comprising disposing a first powder mixture in a first portion of a mold, disposing a second powder mixture in a second portion of the mold, simultaneously molding the first powder mixture and the second powder mixture, and leaching porogen.
TACTILE SYNTHETIC BONES
The present disclosure relates to synthetic bones used in bone-related human and animal education, product demonstration, product development, surgical technique discussions, anatomical demonstrations and biomechanical research. The synthetic bones consisting of cortical an cancellous bones containing a plastic casting resin, a pore inducing additive and a hardness-altering additive.
Bio-Material Composition and Methods of Use
The present disclosure relates to a bio-material composition comprising a dry potassium phosphate based mixture omprising: MgO, monobasic potassium phosphate, monobasic sodium phosphate, proteoglycans, calcium sodium phosphosilicate, and an antibiotic, wherein a weight percent ratio of monobasic potassium phosphate to MgO is between about 3:1 and 1:1, wherein the dry otassium phosphate based mixture is configured to be mixed with the aqueous solution to thereby form a reabsorbable bio-material slurry, wherein the proteoglycans are between about 1-10 weight percent of the dry composition, and wherein the proteoglycans act as active regulators of collagen fibrillogenesis to thereby structure tissue of a patient by organizing a bone extracellular matrix.

Implantable drug eluting device comprising a microporous structure
Implantable drug-eluting device (1) comprising a microporous structure (2) having regularly arranged pores (4, 5) in at least two different uniform sizes, and manufacturing method. The pores are configured for receiving a drug (9) and are being connected by interconnections (6, 7). Interconnections (6) originating from pores (4) of a first size have a first elution area and interconnections (7) originating from pores (5) of a second size have a second elution area. The interconnections convey the drug (9) to a surface of the device for elution to surrounding tissue. The ratio between the first and the second elution areas is predefined and selectable. The differently sized elution areas provide for different outflow rates. This allows for simple but reliable dispensing of drugs at positively controlled and well determined rates. Particularly, this enables a single implantable device to dispense drugs over preselectable durations of time, like short-term or long-term.
Highly flexible degradable fibers
The present invention relates to a method for producing biodegradable fibers on the basis of a silane compound, said silane compound being crosslinked during production and, at least to some extent, an organic acid being incorporated into the forming crosslinked structure via covalent bonds and/or contributing to the crosslinking. The present invention also relates to the fibers that can be produced by the method according to the invention and to the use thereof.
Method for preparing a functionally gradient material for guided periodontal hard and soft tissue regeneration
A functionally gradient material for guided periodontal hard and soft tissue regeneration includes a 3D printed scaffold layer and an electrospun fibrous membrane layer. The content of hydroxyapatite in the 3D printed scaffold layer is higher than the content of hydroxyapatite in the electrospun fibrous membrane layer.
