  • Patent number: 9937328
    Abstract: A positioning method for balloon coating by which the thickness and morphological form of a drug in a coating formed on a balloon can be suitably set. This method is a positioning method for balloon coating for forming a coating layer containing a water-insoluble drug on an outer surface of a balloon of a balloon catheter. The positioning method includes a positioning step in which a dispensing tube is moved, from a state of non-contact with the balloon, in a direction intersecting the extending direction of the dispensing tube, and an opening portion-formed end portion side of the dispensing tube formed at its end portion with an opening portion for discharging a coating solution is thereby placed in contact with the outer surface of the balloon.

  • Patent number: 9855577
    Abstract: A process and apparatus for applying a needle lubricant to a syringe. The interface forces between the needle lubricant and the syringe at the tip of the needle are balanced by optimizing the flow rate of a positively pressurized gas that is delivered to the syringe. Such optimization prevents the formation of bubbles in the needle lubricant that is applied to the syringe, thereby providing a confluent, uniform and smooth lubricant coating on the exterior wall of the needle and prevents lubricant from contaminating inner portions of the syringe. The smooth and uniform lubricant coating may minimize dilation and glide forces and pain associated with the insertion of the needle into a patient's tissue. Additionally, a gas pulse may blows off the droplet of needle lubricant from the tip of the needle to further minimize dilation forces and associated patient pain.

  • Patent number: 9839939
    Abstract: A process includes placing a mask over a substrate; delivering liquid film-forming compositions through the mask to the substrate; removing the mask to leave a multilayered raw shape on the substrate; and curing the multilayered raw shape to form the multilayered shaped film product disposed on the substrate. The mask has a delivery surface, an opposite surface and at least one aperture having a design corresponding to the desired shaped film product. The film-forming compositions are delivered through a multistream nozzle. The movement of the mask and the delivery of the first and second liquid film-forming compositions to the mask aperture are controlled to provide a volumetric flow rate of the first and second liquid film-forming compositions to the mask aperture corresponding to the volume of a void. The nozzle is in contact with the delivery surface of the mask.

  • Patent number: 9833319
    Abstract: The invention relates to biomaterials based on plastics, such as polyaryl polyether ketone (PEK), and to methods for producing and using same. The following describes how a mechanically stable coating made of a porous bone substitute material, e.g. Nano BoneĀ®, is applied to polyaryl polyether ketone (PEK), e.g. polyether ether ketone (PEEK), as a result of which the problem of poor cell adhesion on plastics surfaces of this kind can be solved. The bone substitute material can be applied both dry as a powder and also in a wet spraying method. The coating is a result of briefly melting the polymer surface and the resulting partial penetration of the previously applied layer. In the process, the molten polymer penetrates into nanopores of the bone substitute material and thus establishes a firm connection.

  • Patent number: 9821090
    Abstract: The present disclosure relates generally to coating medical devices. In particular, the present disclosure provides materials and methods for coating a portion of a balloon catheter with a pharmaceutical agent using electrodeposition techniques. Although angioplasty and stenting can be effective methods for treating vascular occlusions, restenosis remains a pervasiveness problem. Therefore, coating portions of a balloon catheter with a pharmaceutical agent that inhibits restenosis can reduce the likelihood of restenosis.

  • Patent number: 9808559
    Abstract: The invention relates to a method for coating a vascular endoprosthesis, wherein the outside of the vascular endoprosthesis is wetted at least partially with a first solution of an active substance, the vascular endoprosthesis is moved in a rotational movement about the longitudinal axis of the vascular endoprosthesis, and a radially acting mechanical force is applied to the outside of the vascular endoprosthesis. The rotational movement has the effect that the solution is carried outward by the centrifugal force, such that no active substance deposits in the interior of the vascular endoprosthesis. The application of a mechanical force to the outside of the vascular endoprosthesis then has the effect of creating crystallization nuclei, such that the active substance can crystallize out.
