    摘要: An acute stroke recanalization system and processes include catheter-based improved reconstrainable or tethered neurological devices which are deliverable through highly constricted and tortuous vessels, crossing the zone associated with subject thrombi/emboli, where deployment impacts, addresses or bridges the embolus, compacting the same into luminal walls which enables perfusion and lysis of the embolus, while the improved neurological medical device itself remains contiguous with the delivery system acting as a filter, basket or stand alone stenting mechanism, depending on the status of the embolus and other therapeutic aspects of the treatment being offered for consideration.

    摘要: A delivery system for deploying a medical device, such as a stent, at increasing deployment speed is described. The system comprises a catheter comprising a catheter shaft, a retractable sheath slidably mounted on the catheter shaft, and the device in a compressed state sandwiched between the shaft and sheath. A control handle is included with a housing and knobs for a user to apply a rotary or other force to retract the sheath. The sheath is attached to a slider that is mounted on a slide rod and attached to a drive belt. A take up pulley is provided in the housing and connected to the belt input knob, so that the pulley turns when the knob is turned. The belt is attached to the pulley so that the drive is wound onto the rotating pulley. As the belt winds upon the pulley, the overall outside diameter of the pulley increases, thereby increasing the deployment speed.

    摘要: A cavitation nozzle includes a hydro-acoustic oscillator, an orifice, and a conical diffuser. The conical diffuser includes a first zone for diffusing a liquid jet, a second zone comprising two or more shear chambers for creating additional cavitation bubbles by creating rotational flow in the chamber, and a third zone which has a diameter larger than the shear chambers or the first zone.

    摘要: An apparatus and method for intraluminal delivery and deployment of an expandable prosthesis at a site within a body canal is provided. The apparatus comprises an elongated sleeve and an outer shaft disposed within the elongated sleeve and movable relative to the sleeve. A securing member is disposed on a distal area of the outer shaft. The expandable prosthesis is housed within a distal area of the elongated sleeve, and a distal area of the prosthesis is secured to the outer shaft by the securing member. The stent is deployed by displacing the sleeve in a proximal direction relative to the outer shaft to expose the stent and by releasing the stent from the securing member. If necessary, the stent can be repositioned prior to releasing the stent from the securing member.
