摘要： PLA polymers that can be expanded into microporous articles having a node and fibril microstructure are provided. The fibrils contain PLA polymer chains oriented with the fibril axis. Additionally, the PLA polymers have an inherent viscosity greater than about 3.8 dL/g and a calculated molecular weight greater than about 150,000 g/mol. The PLA polymer article may be formed by bulk polymerization where the PLA bulk polymer is made into a preform that is subsequently expanded at temperatures above the glass transition temperature and below the melting point of the PLA polymer. In an alternate embodiment, a PLA polymer powder is lubricated, the lubricated polymer is subjected to pressure and compression to form a preform, and the preform is expanded to form a microporous article. Both the preform and the microporous article are formed at temperatures above the glass transition temperature and below the melting point of the PLA polymer.

摘要： A polyethylene powder has a molecular weight in the range of about 300,000 g/mol to about 2,000,000 g/mol as determined by ASTM-D 4020, an average particle size, D50, between about 300 and about 1500 μm, and a bulk density between about 0.25 and about 0.5 g/ml. On sintering, the polyethylene powder produces a porous article having a porosity of at least 45% and a pressure drop less than 5 mbar. The porous article is useful in, for example, wastewater aeration and capillary and filtration applications.

摘要： A bone defect filler for implantation in a bone defect of a patient includes a particulate polymer distributed within a polymeric binder. The particulate polymer includes a plurality of particles, which may have substantially the same material composition as the polymeric binder. The particles of the particulate polymer may be formed in a variety of shapes and/or sizes to provide the bone defect filler with improved pore interconnectivity, material expansion and contamination characteristics, while maintaining sufficient mechanical strength and handling characteristics for bone repair applications. The bone defect filler also provides the flexibility to be molded or shaped in situ to fill the bone defect.

摘要： In general, the invention is directed to techniques for delivery of pacing in response to a premature atrial contraction (PAC) to prevent atrial arrhythmia, i.e., delivery of post-PAC pacing pulses. The techniques may involve monitoring the success rate of prior post-PAC pacing sequences, and adjusting the number of post-PAC pacing pulses delivered subsequent post-PAC pacing sequences based on a success rate. In addition, the techniques may involve adjusting the post-PAC pacing interval based on the success rate.
