  • Publication number: 20200170663
    Abstract: A matter elimination catheter includes a catheter body extending from a catheter proximal portion to a catheter distal portion. The catheter body includes an infusion lumen, an aspiration lumen fluidly isolated from the infusion lumen, and a septum interposed between the infusion and aspiration lumens. A drive shaft is within the infusion lumen and is configured to provide rotation near the catheter distal portion. A guide wire lumen is within the drive shaft, and the infusion lumen, the drive shaft and the guide wire lumen are fluidly separated from the aspiration lumen with the septum. In one example, fluid bearings are formed between one or more of the catheter body and drive shaft or the drive shaft and a guide wire or guide wire liner when supplied with infusion fluid through the infusion lumen.

  • Patent number: 10642327
    Abstract: An electronic device may be provided with a housing surrounding an interior portion of the electronic device. The housing may have one or more layers of material such as fabric layers, polymer layers, and metal layers. An outer fabric layer may have openings between adjacent strands of material such as openings between adjacent warp and weft strands. An inner housing layer such as a layer of plastic or metal may have openings that define airflow entrance and exit ports. The outer fabric layer may overlap the openings of the airflow entrance and exit ports. A fan may draw cooling air into the interior through the airflow entrance port and may expel air through the airflow exit port. An airflow controller in the interior may be controlled by control circuitry based on measurements from temperature sensors. The airflow controller may steer airflow to cool appropriate electronic components in the interior.

  • Publication number: 20190290315
    Abstract: A direct stream hydrodynamic catheter system is provided for the removal of thrombus, lesions and the like including provisions for the infusion of drugs, lysing fluids and the like into a blood vessel. Physician controlled powered direct fluid jet streams emanate from a fluid jet emanatory in the form of robust radially directed fluid jet streams to impinge upon and ablate difficult and strong thrombus and lesions within a blood vessel. Effluent aspiration is controlled by an exhaust regulator in the form of a roller pump, but effluent removal can be assistingly influenced by the fluid pressure associated with the radially directed fluid jet streams.

  • Publication number: 20140214060
    Abstract: A catheter assembly includes an inner mandrel and an outer sheath slidably coupled along the inner mandrel. The catheter assembly includes a scrubbing assembly coupled between the inner mandrel and the outer sheath. The scrubbing assembly includes a plurality of deformable struts deflectable according to movement of the inner mandrel relative to the outer sheath. The scrubbing assembly includes a proximal shoulder coupled with the outer sheath, and a distal shoulder coupled with the inner mandrel. The plurality of struts extend between the proximal and distal shoulders. The scrubbing assembly is movable between a stored configuration and a deployed configuration according to movement of the inner mandrel relative to the outer sheath. In the stored configuration the proximal and distal shoulders are remote from each other. In the deployed configuration the proximal shoulder is engaged with the distal shoulder, and the deformable struts are deflected into bristles.

  • Patent number: 7615031
    Abstract: A gas inflation/evacuation system incorporating a multiple element valved guidewire assembly having an occlusive device for use in thrombectomy or other vascular procedures includes a multiple element valved guidewire assembly having an occlusive balloon removably and sealingly connectible to an included manifold assembly where a guidewire tube defines a lumen for inflation or deflation of the occlusive balloon. A first syringe for evacuating the lumen and a second syringe for introducing a biocompatible gas into the lumen to inflate the occlusive balloon that is in fluid communication with the lumen a plurality of times are included. A sealing valve arrangement selectively seals the proximal portion of the guidewire tube to control inflated or deflated states of the occlusive balloon.

  • Publication number: 20080287986
    Abstract: The present invention is for an arterial closure device which can be used to implement and augment the closure of a femoral artery or other related, adjacent or similar members of the vasculature and to reduce compression times associated therewith. A resorbable tubular plug is introduced through a delivery sheath subsequent to a procedure in which the delivery sheath is first utilized. The resorbable tubular plug is inserted through the delivery sheath and the distal tip of the resorbable tubular plug is positioned a short distance into the artery, whereby a suitable entry can be indicated by blood flow through and from the resorbable tubular plug. The delivery sheath is withdrawn to expose the resorbable tubular plug to the tissue track and to the arteriotomy and manual compression is applied to the wound site to foster and promote hemostasis.
