Catheter Guide Means Patents (Class 600/434)
  • Patent number: 10434272
    Abstract: An insertion guide facilitates insertion of an endotracheal tube (ETT) into the trachea of a patient instead of the esophagus of the patient. The ETT includes an elongated, somewhat flexible, generally hollow tube and the insertion guide includes an elongated, solid and relatively rigid shaft that is configured to be positioned within the hollow tube of the ETT. The shaft is provided with a radiused portion and/or an angled portion adjacent a distal end of the insertion guide that protrudes outwardly beyond a distal end of the ETT. The radiused portion and/or the angled portion of the shaft facilitate insertion of the distal end of the ETT past the epiglottis and into the trachea of the patient instead of into the esophagus of the patient.

The lumen re-entry system also includes a puncture wire slidably received within the helically wound coil and having a distal puncture tip.

  • Patent number: 9895108
    Abstract: Intravascular devices, systems, and methods are disclosed. In some embodiments, the intravascular devices include at least one pressure sensing component positioned within a distal portion of the device. In some instances, a plurality of conductors are electrically coupled to the pressure sensing component and a potting material covers the electrical connections between the plurality of conductors and the pressure sensing component. In some instances, the potting material has a durometer hardness between about 20 Shore A and about 50 Shore A, a moisture absorption rate of about 0% per twenty-four hours, a linear shrinkage of 0%, a coefficient of thermal expansion (m/m/-° C.) of between about 1.0×10?5 and about 5.0×10?4, and a volume resistivity (?-cm) between about 6.0×1013 and about 1.0×1014. Methods of making and/or assembling such intravascular devices/systems are also provided.

  • Patent number: 9861815
    Abstract: A tether subassembly, which may be employed by a tool that deploys an implantable medical device, includes a test segment for verification of adequate fixation of the device at an implant site. When the device is located in proximity to a distal opening of the tube, a tether first length extends through an attachment structure of the device and within an elongate tube of the tool, a tether second length extends alongside the tether first length within the tube, and the test segment is located in proximity to the distal opening. The test segment is configured so that only a tug force, applied to the tether first length, and greater than or equal to a predetermined force, can pull the test segment through an aperture, either of the delivery tool or of the device. The predetermined force corresponds to a minimum adequate fixation force for the device.

  • Patent number: 9833257
    Abstract: A thrombectomy catheter includes a catheter body having a catheter lumen. An outflow orifice is positioned along a catheter perimeter. A fluid jet emanator communicates with a high pressure tube. The fluid jet emanator includes at least one jet orifice for directing a fluid jet from the fluid jet emanator through the catheter lumen toward the outflow orifice. The fluid jet emanator provides a jet stream from the catheter body through the outflow orifice. The jet stream includes first and second stream portions. An entrainment fluid flow circuit includes at least the first stream portion, and the entrainment fluid flow circuit entrains particulate and macerates the particulate therein. An exhaust fluid flow path includes the second stream portion, and the exhaust fluid flow path draws entrained particulate from the entrainment fluid flow circuit at a location exterior to the catheter body and directs it toward the catheter proximal portion.
