摘要： A biomaterial with a thromboresistant surface and a method for forming same are provided. The thromboresistant surface is comprised of a distinct coating layer of a chitosan-based membrane and a biologically active material. The biologically active material is capable of converting the chitosan membrane coating from a highly thrombogenic to an essentially non-thrombogenic one. The biologically active material can be a polymeric substance, such as polyvinyl alcohol, forming a polymeric blend with the chitosan, or, can be a biological substance, such as serum albumin, embedded in or attached to the chitosan membrane which has been activated with a treatment of glutardialdehyde. The thromboresistant biomaterial is suitable for use in vascular grafts having an inside diameter of less than 6 millimeters.

摘要： Improved controlled therapy is provided with a polymer multi-layer structure having a predetermined micro-fabricated spatial pattern (e.g., reservoirs and channels). More specifically, all geometrical details of the spatial pattern are substantially predetermined. The increased control of pattern geometry provided by the invention allows for improved control of therapy. In preferred embodiments, the polymer multi-layer structure of the invention is biodegradable, but has an in vivo lifetime that is greater than the duration of the therapy being provided. Thus, the geometrical pattern of the polymer structure that controls delivery of the therapy persists without significant change during therapy, and the structure degrades after completion of therapy. In this manner, possible interference of degradation by-products with therapy is minimized, and delivery of therapy does not depend on details of how degradation proceeds.

摘要： Methods for compression molding through holes in polymer layers are provided, as are the resulting patterned polymer layers. Two key aspects of the invention are provision of a mold and substrate having different mechanical hardness, and provision of room for local flow of material. These aspects of the invention facilitate formation of through holes by compression molding that are not blocked or partially blocked by undesirable material. These polymer layers can be formed into three dimensional patterned structures by bonding patterned layers together. Since the layers include through holes, a three-dimensional polymer pattern can be formed. These patterned polymer layers and three dimensionally patterned polymer constructs have a wide variety of applications. For example, these constructs can be used for fabrication of micro-fluidic devices, and/or can be used for various medical and biological applications including drug delivery devices and tissue engineering devices.
摘要翻译：提供了聚合物层中的孔的压缩模塑方法，以及所形成的图案化聚合物层。本发明的两个关键方面是提供具有不同机械硬度的模具和基材，并提供用于局部流动材料的空间。本发明的这些方面有助于通过压缩成型形成未被不期望的材料阻挡或部分阻挡的通孔。这些聚合物层可以通过将图案化层结合在一起而形成三维图案化结构。由于层包括通孔，因此可以形成三维聚合物图案。这些图案化的聚合物层和三维图案化的聚合物构造物具有广泛的应用。例如，这些构建体可用于制造微流体装置，和/或可用于各种医疗和生物应用，包括药物递送装置和组织工程装置。
