  • Publication number: 20090287290
    Abstract: A delivery system for delivering a stented prosthetic heart valve to a lumen of a patient, the delivery system including a tubular body having a proximal end, a distal end, and a base portion with a plurality of extending elements, wherein each of the extending elements is engageable with a portion of a stent of a prosthetic heart valve. The delivery system further includes a sleeve having an inner area. The sheath is longitudinally moveable relative to the base portion from a first position where the inner area of the sleeve at least partially covers the extending elements of the base portion to a second position where the extending elements are not positioned within the inner area of the sleeve.

  • Patent number: 7189215
    Abstract: A catheter to be used without a guidewire which includes a support wire shaft formed of metal, a balloon mounted on a distal portion of the catheter, and an inflation shaft for inflating the balloon, wherein a core wire may be interchangeably inserted into the support wire shaft when the catheter is within a human body to change the stiffness and improve control thereof. In one embodiment, the portion of the support wire shaft that extends just proximal of, through and distal of the balloon is formed entirely of a metal wound coil. The flexibility characteristics of this support wire shaft can be controlled by varying the pitch of the wound coil and the thickness of the wire or ribbon it is made from. An overjacket is also provided on the metal wound coil portion to hold pressure within the inflation lumen and provide a suitable material for bonding a distal end of the balloon to the support wire shaft.

    Abstract: A mold for forming medical balloons and the balloons formed therefrom are disclosed. The mold has a generally cylindrical inner molding surface for forming a working length of the balloon, and generally cylindrical outer molding surfaces at either end of the mold for forming shafts of the balloon. Joining these outer and inner molding surfaces are taper molding regions composed of two generally conical molding surfaces oriented at two different angles from a longitudinal axis of the mold. A balloon resulting from a manufacturing process using a mold according to the present invention reflects the geometry of the mold and has a unique concave taper profile and a well-defined working length.

    Abstract: A stent delivery system comprises an inner member and an expandable balloon mounted thereon. The stent has a distal edge and a proximal edge, and at least a portion of the stent has an outer diameter that tapers down towards the distal edge. Each stent segment is comprised of a wire member bent to form a generally cylindrical mesh that includes a plurality of axial bends defining proximal and distal edges of the stent segment. The width and/or outer diameter of the axial bends defining the distal edge and/or the proximal edge may be reduced to provide a low profile.

  • Patent number: 6308603
    Abstract: Previous methods of bucksawing logs slow the throughput of a sawmill in that the conveyor line is stopped while a given log is bucksawed to length. The present invention provides a method for bucksawing a log which improves the throughput speed, comprising the steps of a) advancing the log endwise along an infeed conveyor; b) raising the log above the level of said infeed conveyor while advancing the log; c) measuring the advance of the log while raised; d) stopping the log at the desired length; e) sawing the log to produce a forward log segment; and f) lowering the forward log segment onto an outfeed conveyor while advancing the remaining log segments. An apparatus for carrying out the method is also disclosed.

  • Patent number: 6000016
    Abstract: A microprocessor includes a register file that contains registers for storing pieces of data for use by execution units that receive the pieces of data through source ports. A bypass cache includes data registers into which pieces of data from the execution units are written. Data can be written to and read from the bypass cache in fewer clocks cycles than it can be written to and read from the register file. A content addressable memory array (CAM) includes address registers into which destination addresses are written which correspond to the pieces of data in the data registers. In the case of a particular piece of data, the particular data register into which the piece of data is written and the particular address register into which the corresponding destination address is written is controlled by the position of a write pointer provided by a rotating write pointer unit. The CAM includes a comparators that compare the destination address with a source address.

  • Patent number: 5844852
    Abstract: The precharged bit lines of a memory array are provided with corresponding pass gate devices and a common complementary regulation and control circuitry to keep the precharged bit lines at a voltage below a first voltage and to counter-act any leakage to Vcc through a small current drain to a reference voltage. As a result, the voltage on the precharged bit lines are prevented from moving closer to Vcc, even during a prolonged idle period, and failure will not occur, when the memory cells are accessed again after the prolonged idle period.

  • Patent number: 5796282
    Abstract: The present invention provides a latching mechanism for use in high-speed domino logic pipestages. The latching mechanism allows time borrowing across latch boundaries, provides sufficient hold time for the output to be sensed by the next stage, and provides a circuit configuration in which race conditions related to the latching mechanism have inherent positive margin. The latching mechanism of the present invention is applicable to fully self-resetting domino logic, globally resetting domino logic, or any combination thereof. The latching mechanism is a set dominant latch having its set input driven by the output of the last domino logic gate in a pipestage, and having its reset input driven by the output of the last domino logic gate in a pipestage ANDed with a delayed version of the pulsed clock that triggers the domino chain of the pipestage.
