Abstract: A storage system comprises a plurality of storage nodes each comprising one or more storage devices. At least a given one of the storage nodes is configured to generate data blocks for prefilling of at least a subset of the storage devices, to maintain a first portion of the generated data blocks in a pool of data blocks available in the given storage node for prefilling one or more of the storage devices of the given storage node, and to send a second portion of the generated data blocks from the given storage node to one or more other ones of the storage nodes for prefilling one or more other ones of the storage devices of the one or more other storage nodes. Each of the other storage nodes can similarly maintain a separate pool of generated data blocks for prefilling its corresponding storage devices.

Abstract: A storage system comprises a plurality of storage nodes each comprising one or more storage devices. At least a given one of the storage nodes is configured to read data blocks from its one or more storage devices, and for a given one of the data blocks, to determine based at least in part on a content-based signature of that data block whether or not the given data block is appropriate for use in a prefilling operation of the given storage node. Responsive to the given data block being appropriate for use in the prefilling operation of the given storage node, the given storage node uses the data block in the prefilling operation of the given storage node. Responsive to the given data block not being appropriate for use in the prefilling operation of the given storage node, the given storage node sends the data block to another one of the storage nodes for use in a prefilling operation of that other storage node.

Abstract: Medical device coatings are provided that simultaneously release a therapeutic agent at different rates from different portions of the medical device coating. In a first embodiment, medical device coatings are provided that include particles comprising a therapeutic agent with two or more different particles sizes within a single layer on a surface of the implantable device. In a second embodiment, medical device coatings are provided having a higher concentration of the therapeutic agent in a first region of the coating than in a second region of the coating. In a third embodiment, medical device coatings are provided that are formed by certain coating processes wherein the droplet size of a spray coating solution is changed during the coating process. These coating processes preferably include applying a solution comprising a therapeutic agent and a suitable solvent to a surface of an implantable medical device.

Abstract: A method of coating a stent is provided that minimizes damage to the coating. The stent is self-expanding and made of a superelastic material. The stent is initially cooled so that at least part of the structure of the stent transforms to a martensitic phase. The stent is then compressed, coated and loaded while the structure of the stent remains at least partially martensitic. After the stent is loaded into a tubular restraint, the loaded stent is allowed to warm to room temperature.

Abstract: A hemostatic valve device for use in inserting an interventional device into a body lumen of a patient. The valve device includes a housing that defines a cavity between first and second end openings. A valve structure is disposed within the cavity, and defines a variable diameter channel for receiving the interventional device. An annular chamber is generally formed between the valve structure and the housing inner surface, and can be filled with fluid. The housing is movable between first and second positions so that the volume of the cavity and the diameter of the channel vary to a degree for the valve structure to form a seal along the interventional device inserted within the channel. The valve structure may be configured to seal without substantial twisting.

Abstract: A method for simulating the effect of viewing an image through a colored filter or colored ophthalmic spectacle, contact, intraocular or other lens is described. This method includes using a computer program to alter the red (R), green (G) and blue (B) color brightness of the individual pixels of the original image and then displaying them on the display screen or other visual display device of a computer. Each pixel's original RGB brightness value is multiplied by a fraction, which is determined by the RGB transmission of the colored lens or filter. The altered image is then displayed to a system user who will see the original image, as it would appear if seen through the colored lens or filter.

Abstract: The present disclosure generally provides a multiple balloon assembly used as part of the distal region of a medical device that is capable of delivering a therapeutic agent into a body vessel having bodily fluid. The multiple balloon assembly comprises an inner balloon and an outer balloon. The outer balloon further comprises a proximal taper region, a middle region, and a distal taper region. The inflation of the inner balloon causes the middle region of the outer balloon to contact the inner wall of the body vessel, thereby, occluding the flow of fluid through the body vessel. The proximal taper region and the distal taper region are configured such that they do not touch the inner wall of the body vessel. One of the distal taper and proximal taper regions has a plurality of apertures configured to allow for the therapeutic agent to be delivered into the body vessel at a predetermined rate.

Abstract: A system and method for selecting safer colored ophthalmic spectacle, contact, intraocular and other lenses and filters by quantifying the amount of harmful, higher energy visible and near visible radiation blocked by it compared to the overall visible radiation passing through it is described. A figure of merit, which is produced by the method, is the Wertheim Factor, whose value is nearly 50% for lenses which block the harmful high energy radiation compared to beneficial light and is nearly 0% for lenses which pass all radiation equally. This method includes using a computer program to sample the visible and near visible transmission spectrum of said colored filter or colored ophthalmic spectacle, contact, intraocular or other lens and then evaluate the energy content of the photons present.

Abstract: A spring action medical device includes a spring that may propel a hammer component in a distal direction when the spring is released from a loaded state. When propelled forward by the spring, the hammer component makes contact with a distal tip of the medical device. The distal tip may then transfer a force to an external object, such as an occlusion in a body lumen.

Abstract: An electrospinning apparatus may include a first spinneret and a second spinneret, each including a reservoir and an orifice. The first and second spinnerets may have first and second electrical charges, respectively. The first spinneret orifice may be located substantially opposite the second spinneret orifice. The first and second spinnerets may be used to prepare a medical device defining a lumen with a proximal end, a distal end, a luminal surface and an abluminal surface. The first spinneret orifice distal end may be configured to be located outside of the medical device lumen and between about 0.1 inches and about 6.0 inches from the medical device abluminal surface. The second spinneret orifice distal end may be configured to be located in the medical device lumen and between about 0.1 inches and about 6.0 inches from the medical device luminal surface.
