A centrifugal blood pump driver comprises a motor housing and the housing contains a motor for rotationally driving the centrifugal blood pump and a controller operatively associated with the motor for controlling the rotational speed of the motor; a speed selector for generating a selected speed signal signifying a selected rotational speed for the motor; sensors operatively associated with the motor or controller for sensing the rotational speed of the motor and outputting a monitor signal signifying such rotational speed; program memory for storage of a program of microprocessor readable instructions; a microprocessor under program control, in electrical connection with the controller, the speed selector, the sensor and the program memory, for receiving the selected speed signal and generating a speed control signal to the controller signifying the selected speed for the controller, and for receiving the monitor signal and outputting a display signal; a display in electrical communication with the microprocessor and responsive to the display signal for displaying information; motor housing circuitry for providing electrical communication among the controller, the speed selector, the sensor, the program memory, the microprocessor, and the display; and electrically conductive cable connected to the motor housing circuitry for transmitting electrical DC power to the motor housing circuitry from an external power source.

Centrifugal blood pump driver apparatus

The present invention pertains to an apparatus and method which enable the performance of vertical banded gastroplasty (VBG) without the use of staples. Further, a laparoscopic instrument which can be used in combination with the VBG apparatus and method is also disclosed. The laparoscopic instrument can also be used in combination with surgically functional elements other than the VBG apparatus. A particular advantage of the laparoscopic instrument is that surgically functional elements attached at the leading edge of levered jaws of the instrument can be rotated at least 180 degrees in a plane which is substantially parallel to a plane passing horizontally through the longitudinal centerline of the levered jaws.

Apparatus and method for performing vertical banded gastroplasty

The electric multi-contact connector comprises a pair of plugs, each carrying a plurality of elongated contact members mounted in spaced-apart relationship on an insulating base. Each contact has an unbiased prong-end for mating with an opposite unbiased prong end, and an opposite terminal-end for connection to an electric conductor. The prong-ends of the contacts of both plugs are preferably substantially identical in shape. The base is preferably made at least in part of a resilient material, or the contacts are otherwise resiliently mounted on the base. When the plugs are moved into mating engagement, each pair of mating prong-ends forms an abutting pressure contact establishing a mechanical and electrical connection between the two conductors connected to the terminal-ends of the engaged pair of contacts.

Multi-contact connectors with identical contacts

A waterproof coupler having a casing and a cap to form a junction box for enclosing a junction between a plurality of electric conductors. The casing has a single opening to enclosingly receive the junction. A plug member constructed of resilient material defines passages therethrough for the conductors. The member is adapted, when compressively urged by the cap into sealing position with the opening, to simultaneously seal the casing and the junction between the conductors. The bare ends of the conductors are anchored by solder balls to a disc positioned inside the casing.

Coupler for joining three cables

This invention relates to seismic transducer assemblies for converting compressional wave motion or acoustic energy into electric energy in a fluid medium such as is encountered in marshy terrains. It also relates to an improved method of manufacturing such transducers. The transducer includes a rigid hollow casing having a conical end cap to facilitate planting the casing into the ground. At least one pressure transducer element is mounted in the casing. A water-impervious, pressure-transmitting, insulating core fills the casing's cavity. The material rigidly holds the transducer in place and allows transfer of pressure energy from the fluid medium in which the transducer assembly is submerged, to the inner surfaces of the transducer element.
