  • Publication number: 20180277021
    Abstract: An anatomical model simulator system includes an anatomical model assembly. The anatomical model assembly includes an anatomical model shell having a plurality of apertures defined therein; and a plurality of electrodes. Each electrode of the plurality of electrodes is disposed within one of the plurality of apertures, and each electrode includes at least one of carbon black and silver epoxy. The anatomical model simulator system also includes a model control system. The model control system includes a power supply configured to deliver electrical energy to the plurality of electrodes; and a controller configured to control the delivery of the electrical energy to the plurality of electrodes.

  • Publication number: 20130317542
    Abstract: The disclosure pertains to a delivery system for delivering a left atrial appendage treatment device or the like to a left atrium and methods of use therefor. The delivery system includes a control housing containing a differential displacement mechanism adapted to manipulate the distal end of an elongate steerable catheter through differential displacement of control elements attached proximate the distal end of the elongate steerable catheter. The elongate steerable catheter includes a stiff proximal region, a somewhat more flexible curved intermediate region and a more flexible distal region adapted to be displaced from the plane of the second curved region.

  • Patent number: 7780696
    Abstract: An emboli capturing system captures emboli in a body lumen. A first elongate member has a proximal end and a distal end. An expandable emboli capturing device is mounted proximate the distal end of the first elongate member, and is movable between a radially expanded position and a radially contracted position. When in the expanded position, the emboli capturing device forms a basket with a proximally opening mouth. A second elongate member has a proximal and a distal end with a lumen extending therebetween. The lumen is sized to slidably receive a portion of the first elongate member. An expandable delivery device is mounted to the distal end of the second elongate member and is movable from a radially retracted position to a radially expanded position. The delivery device has a receiving end configured to receive the emboli capturing device, and retains at least the mouth of the emboli capturing device in a radially retracted position.

  • Patent number: 6053932
    Abstract: An emboli capturing system captures emboli in blood flowing in the vasculature. The emboli capturing system includes a guidewire having a longitudinal axis and defining a lumen along at least a portion thereof. An expandable member is coupled to a distal portion of the guidewire and has an interior being in fluid communication with the lumen in the guidewire. The expandable member is configured to receive fluid through the lumen to expand radially outwardly relative to the guidewire and have fluid removed from the interior thereof to collapse radially inwardly relative to the guidewire. The expandable member, when expanded, has a spaced portion thereof spaced radially outwardly from the guidewire. An emboli capturing device is coupled to the expandable member and is configured to deploy radially outwardly relative to the guidewire upon expansion of the expandable member.
