  • Publication number: 20240173519
    Abstract: An intravascular imaging system includes a catheter with an elongate outer sheath and a torque cable axially translatable and rotatable in the elongate outer sheath, a pullback and rotation unit for axially translating and rotating the torque cable, a sensor configured to provide an output indicative of an axial force exerted by the torque cable on a rotor in the pullback and rotation unit, and a controller configured to cause the pullback and rotation unit to operate in a remedial mode if the output exceeds a predetermined threshold.

  • Publication number: 20240131268
    Abstract: A fluid injector system for delivering a multi-phase fluid injection to a patient and methods of fluid delivery is disclosed. Methods of creating and using a multi-aspect fluid path impedance model of the injector system are used. Modeling and adjustment of factors that affect impedance and prevent or reduce backflow, reduce the likelihood of fluid flow rate spikes and provide more accurate flow rates and mixing ratios of fluids may be repeated or happen essentially continuously during an injection. The adjustments may be determined before the injection or determined and/or adjusted during the injection. The determination may include sensor feedback commonly used in injectors such as pressure and position feedback as well as other sensors. In all cases, the user can be notified of adjustments through on-screen notices and/or through the recordation of the injection data by a control device of the injector at the conclusion of the injection.

  • Publication number: 20240117495
    Abstract: Cold thermal chemical vapor deposition coatings, articles, and processes are disclosed. Specifically, a cold thermal chemical vapor deposition process includes positioning an article, heating a precursor gas to at least a decomposition temperature of the precursor gas to produce a deposition gas, introducing the deposition gas to a coating vessel, and depositing a coating from the deposition gas onto the article within the coating vessel. The article remains at a temperature below the decomposition temperature throughout the introducing and depositing of the deposition gas. The coating on the article has a gradient formed by the depositing of the coating having no flow for a period of time. The coated article includes a thermally-sensitive substrate (the thermally-sensitive substrate capable of being modified by a temperature of 300 degrees Celsius) and a coating the thermally-sensitive substrate.

  • Publication number: 20220249057
    Abstract: A method of imaging a vessel with a catheter includes positioning an imaging tip in a reinforced terminal section of an outer sheath of the catheter, inserting the catheter into a vessel, and performing near infrared spectroscopy of the vessel by retracting the imaging tip to a retracted position proximally spaced from the reinforced terminal section of the outer sheath, transmitting near infrared light from the imaging tip to the vessel wall via the outer sheath, and collecting near infrared light from the vessel wall at the imaging tip via the outer sheath. Transmitting and collecting may be performed after retracting the cable and while the imaging tip is rotated and translated proximally from the retracted position along the outer sheath. Ultrasound energy may be transmitted to the vessel from a transducer on the imaging tip and received from the vessel at the transducer.

  • Publication number: 20180227073
    Abstract: A technique for adaptively disrupting UAVs detects a target UAV using a camera, monitors the target UAV's communications using a directional antenna aligned with the camera, and attempts to communicate with the target UAV to request that it land, fly away, or return to launch. With the camera trained on the UAV, the directional antenna detects down-link signals from the UAV, which the UAV may employ to communicate with a ground-based controller. Control circuitry analyzes the down-link signals and generates a disrupting signal based thereon. The disrupting signal shares characteristics with the down-link signal, such as its protocol, bit rate, and/or packet length. The directional antenna transmits the disrupting signal back toward the UAV to affect the UAV's flight.

  • Patent number: 8454683
    Abstract: A system for modifying a heart valve annulus includes a helically helical anchored annuloplasty device delivered to the annulus via an elongated delivery member. The helical anchors of the devices disclosed herein are rotated into the valve annulus along an anchor guide by using a driver that is movably disposed in the delivery member. A tether is disposed within an inner channel of the helical anchor and a locking device is used to secure the annuloplasty device after the valve annulus has been modified. The annuloplasty device can be delivered to the annulus using, traditional surgical approach or a minimally invasive or catheter based methods.
