Abstract: Systems and methods for filtering materials from biologic fluids are discussed. Embodiments may be used to filter cerebrospinal fluid (CSF) from a human or animal subject. In an example, CSF is separated into a permeate and retentate using a tangential flow filter. The retentate is filtered again and then returned to the subject with the permeate. During operation of the system, various parameters may be modified, such as flow rate and waste rate.

Abstract: Embodiments of the present invention are directed to a plurality of substantially spherical microspheres comprising at least one API substantially dispersed in at least one polymer and a lyoprotectant on an outside surface of the plurality of substantially spherical microspheres, wherein the plurality of substantially spherical microspheres have a D99[num] particle diameter of less than about 10 ?m; a D90[num] circularity value of from about 0.8 to about 1.0; and comprise API in a weight of about 20 to about 40 wt. % of the polymer. Other embodiments relate to injectable compositions comprising such microspheres and methods of treating a number of conditions by administering such injectable compositions to a subject.

Abstract: The invention relates to a method for determining the occurrence of a vascular collapse of a blood vessel in or on the eye. According to the invention, it is proposed that the vascular collapse be determined from a measured temporal change of blood flow in the blood vessel.

Abstract: Systems and methods for filtering materials from biologic fluids are discussed. Embodiments may be used to filter cerebrospinal fluid (CSF) from a human or animal subject. The method may include the steps of withdrawing fluid comprising CSF, filtering the volume into permeate and retentate by passing the fluid through a tangential flow filter, and returning the permeate to the subject. During operation of the system, various parameters may be modified, such as flow rate.

Abstract: Various embodiments of an implant devices and systems are provided. The implant devices can include a mesh or implant encapsulated or otherwise coated, in whole or in part, with a film or coating. The coating or film can include methylcellulose or ethylcellulose to provide tissue regeneration as a hydrogel, while also providing a stiff polymer film when dry.

Abstract: Various embodiments of a mesh or implant system are provided for treating pelvic conditions such as incontinence, vaginal prolapsed, and other conditions caused by muscle and ligament weakness. Embodiments of the implants can include a material, substrate, configuration or coating adapted to provide immediate or timed release of various therapeutic agents or drugs to treat the surrounding tissue.

Abstract: A cleaning apparatus for microsurgical instruments has a flush chamber closed off at one end by a first plug adapted to liquid-tightly grip one end of the instrument, allowing a portion of the instrument to extend past the first plug and out of the flush chamber. The other end of the flush chamber is closed off by a second plug having an inlet port. Liquid injected through the inlet port on the second plug passes through an internal passageway formed in the instrument and exits the instrument through the portion that extends past the first plug. In another embodiment the instrument has an internal passageway and an end cap through which flushing ports are formed which communicate with the passageway. A first plug having an inlet port is liquid-tightly attached to the end cap and liquid injected into the first plug passes through the plug, through the flushing ports and through the passageway to clean detritus from the instrument.

Abstract: Compositions, systems, and methods for the treatment of pelvic tissue conditions that include use of a silk fibroin-containing hydrogel composition are disclosed. The composition may include a water-soluble fibroin and a water-soluble crosslinkable polymer that can be used as a pre-formed hydrogel, and/or delivered to a pelvic tissue site and crosslinked in situ to form a hydrogel. The composition may promote tissue closure, such as vaginal wound or fistula closure; and/or enhance attachment or anchoring of a pelvic implant to a pelvic tissue. The composition may be a hydrogel that is delivered to a pelvic tissue site, formed at the site in situ, and/or associated with a portion of the implant (e.g., a mesh implant) via a tether or implant extension portion, thereby providing improved immobilization of the implant. Systems or kits that include the composition and/or a delivery needle or insertion tool are also described.
