Abstract: There is disclosed a porous emboli deflector for preventing cerebral emboli while maintaining cerebral blood flow during an endovascular or open surgical procedure. The device prevents the entrance of emboli of a size able to cause stroke (such as greater than 100 microns) from entering either the right or left common carotid arteries, and/or the right or left vertebral arteries by deflecting emboli downstream of these vessels. The device can be placed prior to any manipulation of the heart or aorta allowing maximal protection of the brain during the index procedure. The deflector has a low profile within the aorta which allows sheaths, catheters, or wires used in the index procedure to pass. Also disclosed are methods for insertion and removal of the deflector.

Abstract: A medical robotic system includes a viewer for displaying an image of a work site, a gaze tracker for tracking a gaze point of a user on the viewer, and a processor. The processor is configured to: draw an area or volume defining shape, overlaid on the image of the work site, in a position determined by the gaze tracker; assign a fixed virtual constraint to the shape and constrain movement of a robotic tool according to the fixed virtual constraint; receive a user selected action command selecting an image of patient anatomy; and superimpose the selected image of the patient anatomy over the image of the work site within the shape. The selected image of the patient anatomy is registered to the image of the work site.

Abstract: Embodiments of the present disclosure relate to a circulatory support device with an integrated cannula. In an exemplary embodiment, an apparatus for attachment to a cardiac pump, comprises an adaptor. The adaptor comprises an annular cross section configured to receive the cardiac pump. The annular cross section is secured to the cardiac pump. The adaptor also comprises a plurality of channels arranged around the adapter and a cannula comprising a proximal portion, a distal portion, and an intermediate portion comprising a braided mesh extending between the distal portion and the proximal portion. The proximal portion has a proximal end comprising a plurality of elements arranged through the channels and the distal portion comprises a plurality of wires and a tip element. The plurality of wires extend in a distal direction from the braided mesh to the tip element and are secured to the tip element. And, a coating covers at least a portion of the braided mesh.

Abstract: Support systems and stands for electronic devices include tilt hinges, lift arms, and their component parts. Some tilt hinges include assemblies for guiding and retaining bars or protrusions into preferred positioning within receiver openings to unify the parts, particularly as they move, and to reduce wobble or slop in the joints. Lift arms provide simplified and low-cost guidance and counterbalance mechanisms for controlling movement of the electronic device relative to the base of a stand. In some cases, the lift arms have sheaths to help protect or cover mechanisms while allowing additional space for the mechanisms within the lift arm. Other interconnection systems hide and protect a connector interface between the stand and the electronic device within a housing until unlocked and the connector is moved into an exposed position. These systems improve efficiency, comfort, ergonomics, accessibility, and user satisfaction of the electronic devices and their supports.

Abstract: A neuromodulation therapy is delivered via at least one electrode implanted subcutaneously and superficially to a fascia layer superficial to a nerve of a patient. In one example, an implantable medical device is deployed along a superficial surface of a deep fascia tissue layer superficial to a nerve of a patient. Electrical stimulation energy is delivered to the nerve through the deep fascia tissue layer via implantable medical device electrodes.

Abstract: A system and method of reinforcing a portion of a pipe, including applying a fiber structure to the portion of the pipe to be reinforced, and pressurizing resin through the fiber structure to the portion of the pipe to substantially saturate the fiber structure with resin, wherein the resin comprises a viscosity of less than about 10,000 cP and a surface tension of less than about 30 dynes. The resin is permitted to cure under ambient conditions at a peak exotherm of greater than about 200° F., wherein the cured resin comprises a glass transition temperature of greater than about 150° F. and a heat distortion temperature of greater than about 150° F. Pressurizing the resin may include use of a reinforcing containment and underlying pliable mold that is compressed to pressure the resin through the fiber structure to the pipe.

Abstract: A method of obtaining positional information about individual wireless devices a1–a16, r1–r125 within a wireless ad-hoc network including a plurality of position determining devices r1–r125 which include means for estimating the distance between themselves and other similar devices which are within range.

Abstract: High friction coatings, compositions for producing such coatings, and non-skid coatings for ships and decks are disclosed. Included are compositions comprising a curable resin, a filler, and aramid in the form of fibers or flakes.

Abstract: In the calibration of a dust concentration measuring instrument at very low dust in gas concentration levels dust is introduced at a known and uniform rate into a gas stream and the instrument is caused to provide a detected concentration value.
