  • Publication number: 20240079027
    Abstract: Provided is a method for detecting a synthetic voice based on a biological sound, the method comprises receiving an audio stream; extracting a biological feature vector corresponding to a meaningless voice from the audio stream; extracting a synthetic voice feature vector from the audio stream; combining the biological feature vector and the synthetic voice feature vector to generate a combined feature vector; and determining whether the audio stream is a synthetic voice based on the combined feature vector. Accordingly, it is possible to detect a synthetic voice at a lower computational cost than a conventional neural network that detects a synthetic voice by learning the correlation between frames.

  • Publication number: 20120226343
    Abstract: A stent delivery system includes a delivery member, a frictional interfacing member disposed on a distal region of the delivery member, the frictional interfacing member comprising a plurality of perfusion channels, a self-expanding stent disposed over the respective frictional interfacing member and delivery member in a radially contracted configuration, and a sheath defining disposed over the respective self-expanding stent, frictional interfacing member, and delivery member, wherein the frictional interfacing member resists axial and/or rotational movement of the stent relative to the delivery member while the stent is in its radially contracted configuration, and wherein the perfusion channels permit fluid to flow from an interior region of the sheath proximal of the frictional interfacing member to an interior region of the sheath distal of the frictional interfacing member.

  • Patent number: 6648854
    Abstract: A single lumen balloon-tipped micro catheter, wherein the distal portion of the shaft is reinforced and extends into the balloon to eliminate abrupt transitions in stiffness in the balloon region. The balloon may be formed of a thermoplastic polyisoprene rubber such as hydrogenated polyisoprene which has superior performance and manufacturing attributes.

  • Patent number: 6629952
    Abstract: The present invention relates to a high pressure vascular balloon catheter wherein the walls of the tube attached to the balloon-forming segment are reinforced with a braided ribbon member. The walls of the inner tube that provides the lumen for a guidewire may also be reinforced in the same way. The reinforcement has the dual effect of providing strength against rupture under pressure and prevention of ovalizing or kinking during insertion into tortuous vessels of a vascular system.

  • Patent number: 6589230
    Abstract: A solderless sacrificial link between a detachable member which is placed at and is intended to remain at a desired site within the mammalian body and the core wire used to introduce the detachable member. The detachable member device may be one used to create emboli in the vascular system or may be of any other type deliverable into the human body and detached into an ionic aqueous environment, either for later removal or permanent placement.

  • Patent number: 6344041
    Abstract: This is an artificial occlusion kit for implanting and retaining an artificial occlusion device in a body space adjacent to and extending from a body lumen in a mammal. The includes at least one occlusion device and a retaining device for blocking the migration of the occlusion device out of the occlusion site. The retaining device is radially expandable at a retaining site adjacent the body space to be occluded to a diameter that is sufficient to engage the body lumen wall at the retaining site and form a barrier across the entrance zone of the body space to be occluded. The expanded retaining device also forms a lumen for flow through body lumen at the retaining site. At least one semi-penetrable space may also be provided in the retaining device, allowing introduction of occlusion devices into the body space to be occluded, but preventing subsequent migration of the occlusion devices out of the body space.

  • Patent number: 6186978
    Abstract: This is a surgical device particularly a perfusion catheter having an inflatable membrane or balloon located at the distal end of the catheter shaft. The catheter shaft is comprised of an outer tubing assembly and an inner tubing assembly separated by an open annulus for inflating and deflating the inflatable membrane. The assembly may additionally comprise an inflatable membrane which is detachable. The outer tubing assembly is made up of at least one polymeric layer and a braid which may be polymeric or metallic, perhaps of a super-elastic alloy. At least a portion of the inner tubing assembly is made up of at least one polymeric layer and preferably a super-elastic metallic braid. The inner tubing assembly includes a lumen through which a guidewire may pass. It is further desirable that the inner tubing assembly include a coil member which generally is coextensive with the balloon along its axis. That lumen is preferably lined with a lubricious polymer.
