Abstract: A valve repair system for repairing a native valve of a patient includes a catheter and a valve repair device. The valve repair device is disposed in the catheter. The valve repair device comprises a compressible spacer and a pair of paddles. The pair of paddles are moveable between an open position and a closed position. The valve repair device can transition to a compressed configuration with the compressible spacer between the pair of paddles in the closed position.

Abstract: A valve repair device for repairing a native valve of a patient includes a pair of paddles and an expanding spacer. The paddles are movable between an open position and a closed position. The expanding spacer is disposed between the pair of paddles. The expanding spacer is configured to be expanded between the paddles when the paddles are moved from the open position to the closed position. The expanding spacer is configured to fill at least a portion of a gap in the native valve of the patient when the valve repair device is attached to the native valve and the expanding spacer is expanded.

Abstract: A delivery handle for implanting a prosthetic device at one of a mitral, aortic, tricuspid, and pulmonary valve region of a human heart includes a housing and an actuation control mechanism. The actuation control mechanism includes a knob and an actuation tube. The knob is rotatably coupled to the housing. The actuation tube is coupled to the knob such that rotation of the knob in a first direction moves the actuation tube distally relative to the housing and rotation of the knob in a second direction moves the actuation tube proximally relative to the housing.

Abstract: Disclosed herein are steerable catheter assemblies that utilize various mechanisms to accomplish independent control of catheter flex magnitude and catheter flex direction to provide improved steerability of an attached catheter. Some embodiments include a catheter with two or more pull wires that flex the catheter and a control handle coupled to the catheter. The control handle can include a direction control coupled to the two or more pull wires such that adjustment of the direction control adjusts a direction of catheter flex by the two or more pull wires, and the control handle can include a magnitude control coupled to the two or more pull wires such that adjustment of the magnitude control adjusts the magnitude of catheter flex.

Abstract: A system for implanting a repair device onto a native valve of a natural heart to repairing the native valve of a patient during a non-open-heart procedure. The system includes a pair of paddles and a pair of gripping members. The paddles are moveable between an open position and a closed position. The gripping members can have different configurations for effective attachment and release from the native valve of the patient.

Abstract: A valve repair delivery handle includes a housing, an actuation control mechanism, and a clasp control mechanism. The actuation control mechanism includes a knob and an actuation tube. The knob is rotatably coupled to the housing. The actuation tube is coupled to the knob such that rotation of the knob in a first direction moves the actuation tube distally relative to the housing and rotation of the knob in a second direction moves the actuation tube proximally relative to the housing. The clasp control mechanism is coupled to the housing.

Abstract: The present invention generally relates to blockchain technology. Specifically, this invention relates to adapting blockchain technology for the storage of voting data in an electronic voting system. The system includes a distributed network of voting machines in communication with each other. Each voting machine has a barcode scanner, a network communications device and a computer system running a voting client. Votes are received through the barcode scanner or a voter interface system and stored securely on a blockchain. The tally for various candidates in the election is updated and stored as each vote is received and counted. This creates an auditable trail of votes and the tally which can be used to detect, correct, and prevent fraud and error in the vote counting process.

Abstract: The present invention generally relates to blockchain technology. Specifically, this invention relates to creating a blockchain called a slidechain that allows for multiple valid branches or forks to propagate simultaneously with a customized set of protocol rules embedded in and applied to each fork chain that branches from another chain. The invention generally provides a computer-implemented method for accessing, developing and maintaining a decentralized database through a peer-to-peer network, to preserve the original state of data inputs while adapting to changing circumstances, user preferences, and emerging technological capabilities.
