Abstract: A needle catheter insertion device that includes a catheter-dilator assembly with a needle therethrough, where the dilator and needle are moveable relative to each other such that the needle catheter insertion device can be moved from a ready position, with the tip of the needle exposed, to a shielded position with the dilator encasing the needle. Positioning of the needle catheter insertion device into the shielded position can be accomplished by a manual actuation of the dilator into a locked configuration within a hub of the needle.

Abstract: Methods and devices to facilitate positioning of a catheter into a vessel. Devices include axially concentric assemblies of a piercing cannula, a shield and tubing such as a catheter where the shield can be passively or actively locked into position over the cannula tip to prevent inadvertent needle sticks.

Abstract: Methods and devices to facilitate positioning of a catheter into a vessel. Devices include axially concentric assemblies of a piercing needle and a dilator that guides an outer catheter into a vessel, such as a blood vessel. The assemblies described herein can include retraction mechanisms and/or lock mechanisms to control needle positioning during catheterization processes as well as improved valves that prevent leakage of fluid from the proximal end of the devices. The devices and method include the use of novel valves to prevent undesired leakage of fluids through the proximal end of the catheter.

Abstract: This invention provides devices and methods for insertion of a catheter into a vessel. The devices include coaxial slidably mourned needle, dilator and catheter components. The methods include piercing a vessel with the needle component, dilating the pierced hole with the dilator component, retraction of the needle component, insertion of the catheter and withdrawal of the dilator.

Abstract: An electric strike having two independent keepers. The strike works with a lockset having both a deadbolt and a mortise lock bolt. A latch adapted to engage a deadbolt is provided with a solenoid to lock or unlock the latch. Another latch adapted to engage a mortise lock bolt is provided with a solenoid to lock or unlock the latch. Each latch is independently operable.

Abstract: Methods and devices for trans-jugular carotid access are disclosed. Methods within the scope of this disclosure include methods of trans-jugular carotid access originating in the leg of a patient or other location remote to the jugular vein and carotid artery and methods originating at the neck of a patient. Devices used in connection with the disclosed methods may comprise access catheters, lumens, and stylets.

Abstract: An electrically or manually actuated locking device comprising a magnetic reed switch as a sensor to monitor whether or not the device is locked. The reed switch is mounted on a circuit board to make a sub-assembly and the sub-assembly is coated with a plastic or other synthetic material which is impermeable to water and/or oil and which provides a degree of mechanical protection from breakage. The coated sub-assembly is then mounted within a housing incorporating the locking device. A pivotable magnet carrier which pivots when the bolt of the locking device is engaged causes the reed switch to be actuated.

Abstract: Various methods employing transvascular access devices are described, including a method of placing a central catheter in a peripheral vein in an arm of a patient; a method of providing percutaneous access to the heart of a patient; a method of clearing a clotted arteriovenous dialysis graft; a method of creating multiple access points into a single blood vessel; a method of creating an AV fistula in a patient; and a method of providing a bypass to a blockage in a popliteal artery in a patient.

Abstract: Transvascular access devices and methods for transvascular access are provided. The transvascular access devices can include a guidewire lumen and a guide tube and stylet disposed in a second lumen. The guide tube can be used to control the orientation of the stylet and provide additional support for the stylet. The methods include providing a second entry point in a vessel of a patient remote from a first entry point. A vascular catheter can enter the vascular system of a patient at a first entry point and be advanced to a second entry point. A guide tube can be advanced out the second lumen of the vascular catheter with a stylet advanced out of the guide tube to pierce the vessel wall and skin of the patient at the second entry point. A catheter can be introduced to the vascular system at the second entry point.

Abstract: The anti-back-flow devices and methods prevent fluid from leaking proximally from a catheter, but allow ready access to the catheter using any male luer device. The devices include proximal surfaces that urge open a valve in response to force from a male luer tip. The valves are associated a female luer hub and adapted to function with standard and typical non-standard male luer fittings.

Abstract: An embodiment is an electromechanical door latch system including a latch device configured for motion between a latched position and an unlatched position. A manually actuated mechanical apparatus is coupled to the latch device and configured to move the latch device to the unlatched position in response to force applied by a user to a component of the mechanical apparatus. An electromechanical actuator system moves the latch device to an actuator unlatched position in response to an electrical signal from an access control device. The electromechanical actuator system includes a control module, a motor, and a ball screw drive including a ball screw or threaded nut, with one coupled to the motor shaft and the other configured for connection to a latch mechanism, and at least one recirculating ball circuit including ball bearings for transferring torque from the motor to the ball screw drive.

Abstract: An enabling platform is provided where an installed agent (e.g., device-side software) may be installed on a mobile device to decode chipset level information readable on the mobile device. Such readable chipset level information can then be transmitted and/or accessed in real-time via a central server for dynamic, real-time, geo-location for mobile device and network performance enhancement. An important feature of the embodiments of the present invention include the ability to decode and transmit chipset level information from a mobile device in real time so that remote field service data gathering, and local headquarter service assessment and issue resolution, may occur more on a contemporaneous basis, permitting faster issue assessment and resolution, which benefits the telecommunications providers and their customers.
