    Abstract: The present invention provides a reparation method of a tubular vascular graft, (a) immersing a tubular scaffold in a first light sensitivity gelatin solution, and irradiate the tubular scaffold by a first time period, to let surface of the tubular scaffold form a base layer; (b) immersing the tubular scaffold of the step (a) in a chitin gelatin solution, when the surface of the base layer form a film, then immersing the tubular scaffold into a sodium hydroxide solution to generate a middle layer of the surface of the base layer; (c) immersing the tubular scaffold of the step (b) in a second light sensitivity gelatin solution, wherein the second light sensitivity gelatin solution comprises a cell, the tubular scaffold is irradiated by a second time period to form a surface layer of the middle layer; (d) until the cell forms a tubular structure of the surface layer by the cell in the tubular scaffold of the step (c), heating the tubular scaffold by a temperature to solve the base layer into a solution, pulling out the tubular scaffold to get an artificial blood vessels.

    Abstract: A plastic overmold aluminum extrusion including at least one plastic overmold and aluminum extrusion. The aluminum extrusion is formed with sufficient cross sectional properties and features such as an internal web to help prevent undesirable collapses under injection or compression molding pressures. This improves part geometry and strength while minimizing weight. A plurality of protrusions and/or local deformations on an outer wall of the extrusion can be used to create strong mechanical interface to the plastic. Localized deformations can result from a combination of the applied plastic pressure under injection or compression molding pressures and the proximity of outer gaps of the internal web structure. A process of making the plastic overmold aluminum extrusion includes inserting at least one aluminum extrusion into a mold without mandrels and delivering plastic forming the plastic overmold.

    Abstract: Disclosed herein is a balloon coating method for forming a coating layer containing a water-insoluble drug on an outer surface of a balloon of a balloon catheter, the balloon catheter including the balloon which is inflatable and provided on a distal portion of an elongate shaft. The balloon coating method includes: accommodating the shaft in a groove portion formed in a support base to extend rectilinearly, and closing at least part of the groove portion with a lid portion, thereby to support the shaft such that the shaft can be rotated within the groove portion; and moving a dispensing tube for supplying a coating liquid containing the drug relative to the balloon in an axial direction of the balloon, while rotating the balloon about an axis of the balloon, thereby to coat the outer surface of the balloon with the coating liquid.
