Abstract: Embodiments of reduced pressure systems and methods for operating the systems are disclosed. In some embodiments, a system can include a source of negative pressure and a controller configured to present GUI screens for controlling and monitoring operation of the system. The controller can be configured to receive, via the GUI, an adjustment of a negative pressure therapy parameter and adjust (or cause adjustment) of the operation of the negative pressure source based on received adjustment. The controller can be further configured to record historical data parameters associated with negative pressure therapy parameters. The controller can also be configured to transmit (or cause transmission) over a communication channel at least some of recorded historical data. The system can be configured to provide external connectivity for accomplishing various activities, such as location tracking, compliance monitoring, tracking of operational data, remote selection and adjustment of therapy settings, etc.

Abstract: An apparatus for delivering therapeutic agent to an eye comprises a body, a cannula, a hollow needle, a cannula actuation assembly, and a needle actuation assembly. The cannula extends distally from the body and is sized and configured to be insertable between a choroid and a sclera of a patient's eye. The cannula actuation assembly is operable to actuate the cannula relative to the body. The needle actuation assembly is operable to actuate the needle relative to the cannula. The cannula may be inserted through a sclerotomy to position a distal end of the cannula at a posterior region of the eye, between the choroid and sclera. The needle may be advanced through the choroid to deliver the therapeutic agent adjacent to the potential space between the neurosensory retina and the retinal pigment epithelium layer, adjacent to the area of geographic atrophy.

Abstract: An apparatus includes a body, a needle, a catheter, and an actuator assembly. The needle extends distally from the body. The needle has an inner wall defining a needle lumen. The needle lumen is in fluid communication with a fluid port of the body. The catheter is slidably disposed in the needle lumen. The catheter has a catheter lumen. The first actuator assembly is configured to translate the catheter within and relative to the needle. The apparatus may also include an actuator assembly that is configured to rotate the needle relative to the body. The apparatus may be used to first deliver a leading bleb of fluid to the subretinal space in a patient's eye via the needle. The apparatus may then be used to deliver a therapeutic agent to the subretinal space in the patient's eye via the catheter.

Abstract: A device for removing an enclosure from a container includes a housing at least partially enclosing at least one reversible motor and at least two spaced-apart cams. The cams are rotatable in a first rotational direction in which the cams grasp the container and in a second rotational direction in which the cams are rotated a predetermined distance away from the container. A wrench disk is operatively connected to and rotatable by the at least one motor. At least two spaced-apart wrenches are pivotally attached to the wrench disk for removably grasping the enclosure. Operation of the motor in a first direction rotates the wrench disk in a first rotational direction causing the wrenches to grasp and rotate the enclosure relative to the container. Operation of the motor in a second direction rotates the wrench disk in a second rotational direction causing the wrenches to rotate a predetermined distance away from the enclosure.

Abstract: A keyless locking system for a cart includes a lock mechanism with a drive mechanism in the form of a solenoid that is electrically coupled to an integrated circuit and a long lasting power supply. In an unenergized state, an armature of the solenoid prevents operation of the lock mechanism to release drawers supported by the cart. Upon entry of a correct access code via a keypad associated with the integrated circuit, current is supplied to the solenoid to permit operation of the lock mechanism and thereby release the drawers. Advantageously, the lock mechanism only draws from the power supply to temporarily release the solenoid only thereby requiring minimal power and significantly reducing the re-charging, replacement and maintenance requirements for the power supply and the down time for the cart.

Abstract: A gas turbine engine has a core frame separable from a vane frame for removably attaching the vane frame to a core structure through a mid ring. The mid ring includes an annular forward panel and an annular aft panel, each of which has a radially outer flange and a radially inner flange. The inner flanges are welded to the core frame and the outer flanges are bolted to the vane frame. A plurality of circumferentially spaced stiffeners extend between the forward and aft panels, with each of the stiffeners including a pair of stringers extending diagonally across the stiffeners. Panels may be incorporated with the stringers between the triangular shaped areas adjacent the forward and aft panels of the stiffener. The bolted connection between the mid ring and the vane frame includes a plurality of tongue and groove joints formed in the flanges of the mid ring and vane frame. The tongue and groove joints provide additional radial support for the core engine within the vane frame.
