Abstract: A bioreactor vessel includes a bottom, a peripheral sidewall, the bottom and the peripheral sidewall defining an interior space for receiving a flexible bioprocessing bag, a recess in the bottom for receiving a base plate of the flexible bioprocessing bag, and a locking mechanism configured to retain the base plate in the recess.

Abstract: A sparger assembly (700) for a bioprocessing system includes a base plate (710) and at least one aeration manifold (712, 714) removably connected to tire base plate. Each aeration manifold includes at least one inlet for receiving a gas and a plurality of gas outlet openings for delivering tire gas to a fluid within the bioprocessing system. An impeller assembly (740) fora bioprocessing system includes a hub and at least one blade (742) operatively connected to the hub. The at least one blade includes a first portion connected to the hub and extending generally vertically, and a second portion extending at an upward angle from tire first portion.

Abstract: A field programmable microwave array is provided. The field programmable microwave array includes one or more RF elements interconnected by an array of switching elements. The switching elements enable the field programmable microwave array to perform one or more RF or microwave subassembly functions.

Abstract: The present invention comprises compositions and methods for use of an alginate dural sealant in conjunction with mammalian neurosurgical procedures, including but not limited to, the implantation of neuroprosthetic devices.

Abstract: The present invention comprises compositions and methods for forming an endovascular occlusion to treat conditions such as aneurysms, arterio-venous malformations, excessive blood supply to tumors, massive vascular hemorrhaging, and other conditions which require an embolization to alleviate the condition. Embodiments of the present invention comprise compositions and methods that use calcium alginate, without or without endovascular coils or similar devices, to form occlusions at a site within the mammalian body targeted for occlusion.

Abstract: A method for forming an endovascular occlusion by controlling the injection parameters of a purified alginate liquid and a calcium chloride solution to meet and polymerize at a target site within the vascular system. Different types of injection techniques may be used with a preferred injection technique of simultaneous bi-directional injection where the purified alginate liquid is injected through a vein and the calcium chloride solution is injected through an artery.
