A system, apparatus and method for delivering negative pressure and vibrations proximate a wound site. The system comprises a dressing adapted to be fluidly coupled to the wound site and further adapted to translate vibrations to the wound site. A pad is coupled to a negative pressure source and to the dressing. The pad is also coupled to a vibration module. The system further comprises a drape covering the dressing and the pad and forming a seal between the wound site and the environment. The vibration module fluidly couples to the dressing and provides vibrations during application of negative pressure.

Provided herein are intranasal fluid delivery devices and apparatus comprising a dispensing tip a shot chamber carrying a fluid, the shot chamber having a diaphragm at one end and a plunger at the other end, and an actuator connected to a push rod moveable toward the shot chamber.

A negative-pressure cup structure includes a cup and a vibration generating mechanism. The cup has a chamber. Two ends of the cup are separately formed with an opening end and a closed end. The closed end is provided with a negative-pressure suction hole and an electric connection hole communicating with the chamber. A bar is extended from the closed end and located in the chamber. The vibration generating mechanism includes a box, a vibration member disposed in the box and a power connector electrically connected to the vibration member. The vibration generating mechanism is fixed in the chamber of the cup in a manner of the box and the bar being connected and the power connector being inserted to the electric connection hole. Therefore, the users may obtain a better vibrational sense.

A system for traversing an arterial occlusion in an artery includes a housing sized to fit in a palm of a user, an elongate drive tube configured to be rotated by the housing, the drive tube including an axially extending passage, a cylindrical member, configured to be rotationally coupled to the drive tube, such that a distal tip of the cylindrical member may be delivered to a location adjacent the arterial occlusion when the cylindrical member is coupled to the drive tube, and wherein grasping and activating the housing such that the drive tube is rotated, thereby causes the distal tip of the cylindrical member to be rotated, the rotation of the distal tip including at least a component of linear oscillation.

The subject matter described herein provides systems and techniques for enhancing a user’s performance. In particular, the physiological characteristics of the user can be altered toward target characteristics to bring about a particular physiological state in the user. Multiple physiological signals of the user may be sensed. Physiological characteristics indicative of a physiological state of the user may be determined. A differential between the physiological characteristics and selected target physiological characteristics may be determined. A selected energy signal associated with a correction action may be communicated to nerves associated with the user’s skin by outputting, using an energy generator, the energy signal toward the skin with one or more different energy types based on the differential. This may allow a particular targeted physiological state to be more rapidly brought about in the user.

A surgical cassette for an ophthalmic surgical system includes an irrigation system, an aspiration system, and a computer. The irrigation system is in fluid communication with a handpiece and carries fluid toward a surgical site. The aspiration system is in fluid communication with the handpiece via an aspiration conduit and carries fluid away from the surgical site. The computer instructs the aspiration system to vibrate fluid back and forth within the aspiration conduit to perform a priming procedure.

A surgical cassette for an ophthalmic surgical system includes an irrigation system and an aspiration system. The irrigation system is in fluid communication with a handpiece and carries fluid toward a surgical site. The aspiration system is in fluid communication with the handpiece and carries fluid away from the surgical site. The aspiration system includes an aspiration pump and tubing of an aspiration conduit. The aspiration pump generates a normal vacuum pressure within the aspiration conduit to carry fluid away from the surgical site during normal operation. The tubing has a larger cross-sectional area in response to normal vacuum pressure. The tubing collapses from the larger cross-sectional area to a smaller cross-sectional area in response to an occlusion; maintains the smaller cross-sectional area during a post-occlusion break surge to mitigate the post-occlusion break surge; and returns to the larger cross-sectional area after the post-occlusion break surge.

A surgical cassette for an ophthalmic surgical system comprises an irrigation system and an aspiration system. The irrigation system is in fluid communication with a handpiece and carries fluid toward a surgical site. The aspiration system is in fluid communication with the handpiece via an aspiration conduit, and carries fluid away from the surgical site. The aspiration system comprises a chamber that expands to store fluid, and collapses to move the fluid to meet a volume demand in the aspiration conduit to mitigate a post-occlusion break surge.

The present invention relates to an automated stimulation device for inducing a tactile inter-stimulus onset asynchrony (ISOA) effect in a subject suffering from apnea, bradycardia and/or hypoxia, the device comprising at least two actuators configured for contacting a body portion of the subject, and interspaced for producing an apparent tactile movement in the subject upon sequential induction of actuation, wherein the duration of the actuations and the overlap in actuation time between the at least two actuators is controlled to attain an inter stimulus onset asynchrony (ISOA).

Proposed devices operate on positive pressure with as little as 5-6 ml of air and can efficiently empty (emitted doses >80%) and deliver the aerosol to infant lungs (lung delivery efficiency of ˜60% of the loaded dose). Significant features include internal flow structure of the air-jet DPI, automatic gas sources, infant-specific interfaces, small diameter nasopharyngeal tubes, sealed nasal prongs, 3D rod array preceding patient interface, nasal CPAP rapid aerosol delivery system, nasal CPAP streamlined interface, multidose storage and delivery unit, and pressure sensing near the infant airways (at the nasal cannula interface).
