20140154795 | BIOREACTOR USING ACOUSTIC STANDING WAVES - A perfusion bioreactor includes at least one ultrasonic transducer that can acoustically generate a multi-dimensional standing wave. The standing wave can be used to retain cells in the bioreactor, and can also be utilized to dewater or further harvest product from the waste materials produced in a bioreactor. | 06-05-2014 |
20140319077 | EXCIPIENT REMOVAL FROM PHARMACOLOGICAL SAMPLES - Active pharmaceutical ingredients can be separated from their excipients by dissolving a pharmaceutical product (e.g. tablet, pill) into a solvent, then running the solution through an acoustophoretic device. Standing waves are used to separate the excipient from the active ingredient dissolved in the solvent. | 10-30-2014 |
20140329997 | ACOUSTIC BIOREACTOR PROCESSES - A series of multi-dimensional acoustic standing waves is set up inside a growth volume of a bioreactor. The acoustic standing waves are used to hold a cell culture in place as a nutrient fluid stream flows through the cell culture. Biomolecules produced by the cell culture are collected by the nutrient fluid stream and separated downstream of the cell culture. | 11-06-2014 |
20150125948 | ACOUSTOPHORESIS DEVICE WITH MODULAR COMPONENTS - An acoustophoresis device made up of modular components is disclosed. Several modules are disclosed herein, including ultrasonic transducer modules, input/output modules, collection well modules, and various connector modules. These permit different systems to be constructed that have appropriate fluid dynamics for separation of particles, such as biological cells, from a fluid. | 05-07-2015 |
20150252317 | DISPOSABLE BIOREACTOR WITH FILTRATION SYSTEM - A disposable bioreactor system includes a bag having a first end and a second end. An acoustophoresis device is disposed at the first end of the bag, and is separable from the bag. An actuating mechanism is operably connected to the second end of the bag. The actuating mechanism is configured to move the second end of the bag towards the acoustophoresis device, so that fluids within the volume of the bag flow past the acoustophoresis device and carry desired biomolecules out of the bag for collection, while cells and other debris remain within the bag for disposal. | 09-10-2015 |
20150257987 | INJECTABLE ALLOPLASTIC IMPLANTS AND METHODS OF USE THEREOF - Described herein are injectable alloplastic implant compositions that are particularly useful for soft tissue defect augmentation. The compositions include microparticles, such as polymethylmethacrylate particles, and collagen as a suspending agent, wherein the collagen contains a reduced amount of low molecular weight gelatine compared to high molecular weight collagen. By controlling the molecular weight of the collagen in the compositions, the injectability, stability, and antigenicity of the alloplastic implant compositions can be improved. | 09-17-2015 |
20150258135 | INJECTABLE ALLOPLASTIC IMPLANTS AND METHODS OF USE THEREOF - Described herein are injectable alloplastic implant compositions that are particularly useful for soft tissue defect augmentation. The compositions include microparticles, such as polymethylmethacrylate particles, and collagen as a suspending agent, wherein the collagen contains a reduced amount of low molecular weight gelatine compared to high molecular weight collagen. By controlling the molecular weight of the collagen in the compositions, the injectability, stability, and antigenicity of the alloplastic implant compositions can be improved. | 09-17-2015 |
