Abstract:
Apparatus and methods for delivering prosthetic segments to a body lumen, utilize a device having an elongated flexible member including proximal and distal ends, a plurality of prosthetic segments releasably arranged axially along the elongated flexible member near the distal end and an outer sheath slidably disposed over at least a portion of the prosthetic segments. The apparatus further includes a separator disposed on the outer sheath and adapted to engage the prosthetic segments. The separator is also adapted to be retracted proximally over the prosthetic segments and advanced distally to separate a proximal group of the prosthetic segments from a distal group of the prosthetic segments which are to be deployed in the body lumen.
Abstract:
Catheters, kits, and methods are provided for removing material from a body lumen. The catheters and methods may be used in a variety of body lumens, including but not limited to coronary and other arteries. In general, the catheter has a cutting element that cuts material while the material is engaged by a material capture device on the catheter body. Preferably, the material capture device tensions the material during cutting, which reduces the amount of cutting force required. The material capture device typically follows a path that draws material into the catheter body. Preferably, but not necessarily, the material capture device may be arranged on the catheter body to advance along a path outwardly from the catheter body into the material and then inwardly towards the catheter body to tension the material. The cutting element on the catheter body moves between a first position and a second position to cut the material while in tension.
Abstract:
Method for drilling horizontal or deviated water wells through hard and fragmented rock formations that are prone to caving, such as Hawaiian basalts. The method may be used to drill into basal aquifers directly underlain by salt water, compartmented aquifers, and perched aquifers. The method uses deviated drilling and may use formation pre-grouting, casing drilling, and/or percussion drilling, and a percussion drilling tool may be combined with a casing drill string.
Abstract:
A method is disclosed for mixed enclave operation of a computer network with users employing a multi-level network security interface and users without any network security interface. Either the network security user selects or the network security interface automatically selects whether communications are permissible with other unsecured users. Where a mixed enclave operation is selected, the network security user identifies when communications are being undertaken with another secured user or a non-secured user. Communications with a non-secured user at a lower security level entail securing the data residing with the secured user from transmission back to the non-secured user.
Abstract:
The invention limits water level in a rinse cycle to a fraction of the water in the wash cycle. A microprocessor based electronic circuitry device that may be wired inside the front panel of the normal (factory) “top loading” automatic clothes washer or a “front loading” automatic clothes washer. Interfaces exist to the water valves and timer motor from the micro-controller. The retrofitted on original equipment micro-controller commands the hot and cold valves to start filling the tub and measures the analog water level input from the water level sensor. This number is stored in the micro-controller memory as a “wash water level” during a first cycle (wash cycle). If the Water Saver Disable switch is enabled by an operator the “Wash Water Level” is divided by two providing a “Rinse Water Level” (second cycle) that is one half the wash or first cycle, or another fraction of that amount.
Abstract:
Prosthesis delivery devices and methods are provided that enable precise control of prosthesis position during deployment. The prosthesis delivery devices may carry multiple prostheses and include deployment mechanisms for delivery of a selectable number of prostheses. Control mechanisms are provided in the prosthesis delivery devices that control either or both of the axial and rotational positions of the prostheses during deployment. This enables the deployment of multiple prostheses at a target site with precision and predictability, eliminating excessive spacing or overlap between prostheses. In particular embodiments, the prostheses of the invention are deployed in stenotic lesions in coronary or peripheral arteries, or in other vascular locations.
Abstract:
Pressure is measured on both sides of an occluding member for determining when pressure forces on the occluding member may cause migration of the occluding member. An alarm indicates when the pressure force on the balloon exceed a predetermined threshold. In another aspect of the invention, a pressure monitor determines when a rate of pressure increase with respect to the fluid volume in the balloon reaches a predetermined threshold when inflating the occluding member. A predetermined amount of fluid is then added to the balloon so that the balloon is not under inflated or over inflated.
Abstract:
Apparatus for delivering stents to body lumens include a flexible catheter shaft, an expandable member, a tubular prosthesis selectively movable in an axial direction over the expandable member, and a stop member disposed on the catheter shaft near the distal end of the catheter shaft for stopping the prosthesis at a deployment position on the expandable member. A variety of different stop members are provided according to various embodiments, such as stop members disposed outside the expandable member, stop members disposed inside the expandable member, movable stop members, and the like. Methods of delivering stents are also provided.
Abstract:
A flipgrip system for a phone. The flipgrip includes two hinging legs that unfold into an X shape, and fold flat. A ring adheres to the rear of the phone and a base can snap onto the ring. The base can spin relative to the ring and also be removed from the back of the phone. The first and second legs hinge relative to the base, out into the X shaped position, or in to the folded flat position.
