  • Patent number: 8777968
    Abstract: A tissue fastening device includes a suture clip holder and a suture cutter. A suture clip can be releasably secured to the suture clip holder, and a suture line or lines can pass through the clip and adjacent the suture cutter. A first movement of a control handle causes the suture clip to be released from the suture clip holder, and a second movement of the control handle causes the suture cutter to cut the suture line or lines. The first movement is different from the second movement. The first movement can be rotational, with the second movement being longitudinal. Alternatively, the first movement can be longitudinal, with the second movement being rotational. The device may include a main body, an inner body, and an outer body.

  • Publication number: 20140058502
    Abstract: Embodiments of the present disclosure provide a delivery apparatus for delivering a prosthetic heart valve to a native valve site via the human vasculature without the need for a separate introducer sheath. The delivery apparatus is particularly well-suited for advancing a prosthetic valve through the aorta (i.e., in a retrograde approach) for replacing a stenotic aortic valve.

  • Publication number: 20130030519
    Abstract: Described herein are systems and methods from delivering prosthetic devices, such as prosthetic heart valves, through the body and into the heart for implantation therein. The prosthetic devices delivered with the delivery systems disclosed herein are, for example, radially expandable from a radially compressed state mounted on the delivery system to a radially expanded state for implantation using an inflatable balloon of the delivery system. Exemplary delivery routes through the body and into the heart include transfemoral routes, transapical routes, and transaortic routes, among others.

  • Patent number: 7586648
    Abstract: A method for enabling a program that communicates a document description from a composition system to a printing system to manage variable-dot halftones for use with variable-dot printing devices, comprising the steps of using a selected halftone cell size to choose an array comprising at least one string defining a halftone cell intensity value, said string comprising at least one pixel imbution value, wherein said pixel imbution value is in the range of 0 to P, wherein P is the number of physical appearances that a painted pixel can have; using a selected halftone cell intensity value to choose a string; and painting at least one pixel within a halftone cell according to a pixel imbution value within the chosen string.

  • Patent number: 6971058
    Abstract: A method and apparatus for searching for a character pattern within a data stream. A checksum is computed for one or more patterns for which the data stream will be searched. The patterns may be of the same length or they may be of different lengths. A shift register is used to sequentially parse through the data stream and compute the checksum of a series of bytes in the data stream. If the checksum of the bytes in the data stream that have been shifted into the register matches the checksum from one of the character patterns, then the character pattern corresponding to the checksum has been found. The system may search multiple character patterns simultaneously by using multiple checksum generators in parallel.

  • Patent number: 6928056
    Abstract: A system and method are provided for identifying an error condition and the sequence of a high bandwidth data stream that is split among low bandwidth links. The system includes a first unit coupled to links for inverse multiplexing a data stream into frames that are transmitted over at least two links and a second unit at the second location coupled to the other end of the links for receiving the frames and multiplexing the frames to produce the cell stream, wherein the first unit inserts at least one detection cell into each frame prior to transmission and the second unit analyzes the detection cell to determine if an error condition exits. The method includes establishing a size for a detection cell and a frequency of insertion into the data stream, determining a known signal that will be part of the detection cell, inserting the detection cell into the data stream, and analyzing the received detection cell at the second unit to determine if an error condition exists.

  • Patent number: 6708168
    Abstract: Methods and apparatus for parallel searching through a data stream. Using a register bank and comparators, the device performs a brute force search through a data stream to quickly find one or more patterns therein. The invention sacrifices physical space for speed by using multiple comparators on the same register bank. The output of the comparators is fed into a decoding circuit which determines the locations of matches and mismatches. Matches are compared against a database/table to determine their significance.
