Abstract:
A catheter assembly (10) having an outer catheter (12) and an inner catheter (14) extending coaxially through the outer catheter, and a hub (16). The inner catheter (14) is axially movable within and with respect to the outer catheter (14) by use of an actuator assembly (130) such that the catheter assembly has an opened condition permitting fluid communication with the vasculature of a patient, and a closed condition preventing fluid communication with the vasculature. The opened condition permits the intended use of the catheter assembly such as for hemodialysis of the patient. In the closed condition, locking solution may be maintained in the catheter assembly and later removed therefrom, with essentially no locking solution leaving the catheter assembly or entering the patient. The actuator assembly (130) is secured to the proximal end portion (128) of the inner catheter (14) as it protrudes proximally from the hub (16), where it is accessible to the practitioner. The actuator assembly (130) may comprise an adapter sleeve (90) fixed to the inner catheter (14), and a swivel sleeve (92) which is rotatable with respect to both the adapter sleeve (90) and the hub (16).
Abstract:
A system and method for providing links to a browser program running on a computer connected to a network include receiving a request from the browser program to transfer a file representing a home page for display in the browser program, and determining a storage location on the computer for links used by the browser program. The system and method may include requesting permission to modify links used by the browser program prior to transferring a list of links to the storage location on the computer for subsequent use by the browser in retrieving information from the network. The list of links may be statically or dynamically generated with one or more links provided by a link server on the network. In one embodiment, accounting information relative to the number and type of links transferred to the user's computer is collected and may be forwarded to an associated billing computer located on the network.
Abstract:
A probe measurement system for measuring the electrical characteristics of integrated circuits or other microelectronic devices at high frequencies.
Abstract:
A drilling system utilizing a plurality of independent telemetry systems. The drilling system uses a drill collar as a pressure housing for downhole components of the system. One or more sensors are disposed within the pressure housing. These sensors can be MWD sensors, LWD sensors, or both MWD and LWD sensors. A plurality of independent borehole telemetry systems is used to telemeter sensor response data to the surface of the earth. Each sensor cooperates with a downhole component of at least one of the independent telemetry systems. The plurality of telemetry systems can be of the same type, such as a mud pulse systems. Alternately, the telemetry systems can be of different types including a mud pulse system and an electromagnetic system.
