A system for manufacturing an artificial construct suitable for transplantation into a biological organism that includes a two or three three-dimensional preform that is based on the actual two or three-dimensional structure of a native mammalian tissue; and an electrospinning apparatus, wherein the electrospinning apparatus is operative to deposit at least one layer of polymer fibers on the preform to form a polymer scaffold, and wherein the orientation of the fibers in the scaffold relative to one another is substantially parallel.

The present invention relates to a novel composition based on ABA triblock copolymers comprising two styrene thermoplastic end blocks A and a central elastomeric block B which is a saturated olefin, comprising at least one resin chosen from the aromatic resins, that can be used in particular for producing an interface dressing with reinforcement, with a support or which is self-supported, preferably self-supported. The present invention relates to a self-supported interface dressing which can be easily handled since it has good tear strength.

Expanded, nanofiber structures comprising electrospun nanofibers, a plurality of holes, and, optionally, cells are provided. Methods of making the nanofiber structures as well as methods of use thereof, particularly for wound healing, are also provided.

A balloon catheter is disclosed having a balloon at a distal portion of a catheter shaft and on a surface of the balloon are elongate bodies which are crystals of a water-insoluble drug having independent long axes. The balloon in a deflated state has a plurality of wing portions in a circumferential direction of the balloon, and a circumferential surface portion along a circumferential direction of the catheter shaft, the plurality of wing portions being folded along the circumferential direction of the balloon. A surface of the circumferential surface portion which faces the plurality of wing portions that are folded has a region in which tip portions are not in contact with the surface of the balloon or with other elongate bodies, and a surface which faces the plurality of wing portions that are folded which faces an outer circumferential side has a region in which the tip portions are in contact with the surface of the balloon or with the other elongate bodies.

Gold implant having a cross-section in the range of 20-100, preferably in the range of 20-40 μm for use in therapy to prevent or reduce capsular contracture. Further, the invention relates to a method of producing a gold-coated implant.

The present invention provides methods for making and using antibacterial polymeric materials loaded with additives, as well as antibacterial materials comprising additives. Certain additives or combinations of additives show unexpected combinatorial or synergistic antibacterial activity. The invention also provides medical devices comprised of antibacterial polymeric materials, and methods of making and using such devices, which can have unexpected combinatorial or synergistic antibacterial activity.

Methods for manufacturing drug delivery systems are provided. The drug delivery systems may include a substrate coated with at least one polymer and at least one active compound. The substrate may include yarns, yarn precursors, threads, filaments, fibers, and/or other suitable substrates. The methods may include disposing a solution including a monomer and an active compound on the substrate. The methods may also include exposing the solution and the substrate to UV light to initiate polymerization of the solution.

An absorbable stent includes an absorbable matrix. The matrix includes a number of wave-shaped rings connected by connection units and arranged in an axial direction. The wave-shaped ring includes a number of waves arranged in a circumferential direction. A peak, a valley and a support connecting the peak and the valley form the wave. Two adjacent wave-shaped rings and the connection unit form a closed side supporting unit. The matrix has a volume of 4 μm to 40 μm per unit blood vessel area. The absorbable stent has sufficient radial supporting strength of no less than 55 kPa for clinical applications. Moreover, the volume of the matrix per unit blood vessel area is less than volumes of existing stents. When the absorbable stent and existing stents are made of the same material, the absorbable stent has a shorter degradation and absorption cycle.

Transcervical access systems for providing transcervical movement of fluids are described. The transcervical access systems are effective for transferring a broad range of fluids, including the delivery of hydrogel precursors, saline, and imaging fluids, to the uterine cavity. The transcervical access systems are also effective for removing fluids from the uterine cavity, such as residual bodily fluids, residual fluids from a procedure, or tissue. The transcervical access systems described include flow limiters, such as egress limiters and/or cervical plugs. Methods of use of the transcervical access systems are also described. Methods include using the transcervical access systems to transcervical access the uterine cavity and install hydrogel. The transcervical access systems and associated methods can be useful for providing degradable hydrogel in the uterine cavity, including the cervical canal, for the prevention of adhesions following intrauterine procedures.

A composition for treating a patient with a tissue disease or malformity has a composition containing amniotic fluid. The amniotic fluid has a quantity of gender specific amniotic fluid based on a gender of a fetal source. A method of treating a patient with a tissue disease or malformity comprises the steps of: identifying the tissue region to be treated and selecting a location to apply either topically or by injection or inhalation a composition containing amniotic fluid; selecting the composition containing amniotic fluid wherein the amniotic fluid has a quantity of gender specific amniotic fluid based on a gender of a fetal source allowing more specific targeted growth factors to be used for specific disease processes; and applying or injecting the composition at or into the selected location.
