摘要： Systems and methods for the intravascular treatment of clot material within a blood vessel of a human patient are disclosed herein. A method in accordance with embodiments of the present technology can include, for example, engaging an interventional device of a catheter system with clot material in a blood vessel and withdrawing the interventional device and the portion of the clot material through a guide catheter. In some embodiments, the catheter system can include an attachment/valve member coupled to a proximal portion of the guide catheter, and the method can include unsealing the attachment/valve member to facilitate withdrawing the interventional device through the attachment/valve member without significant retention of clot material within the attachment/valve member. The method can further include resealing and aspirating the guide catheter before advancing another interventional device to the clot material to again engage and remove clot material from the blood vessel.

摘要： Intravascular devices, systems, and methods are disclosed. In some instances, the intravascular device is a guide wire with electrical conductors embedded within a core wire. In some instances, the electrical conductors are coupled to conductive bands adjacent a proximal portion of the guide wire and a sensing element adjacent a distal portion of the guide wire. Methods of making, manufacturing, and/or assembling such intravascular devices and associated systems are also provided.

摘要： Mechanical circulatory supports configured to operate in series with the native heart are disclosed. In an embodiment, an intravascular propeller is installed into the descending aorta and anchored within via an expandable anchoring mechanism. The propeller and anchoring mechanism may be foldable so as to be percutaneously deliverable to the aorta. The propeller may have foldable blades. The blades may be magnetic and may be driven by a concentric electromagnetic stator circumferentially outside the magnetic blades. The stator may be intravascular or may be configured to be installed around the outer circumference of the blood vessel. The support may create a pressure rise between about 20-50 mmHg, and maintain a flow rate of about 5 L/min. The support may have one or more pairs of contra-rotating propellers to modulate the tangential velocity of the blood flow. The support may have static pre-swirlers and or de-swirlers. The support may be optimized to replicate naturally occurring vortex formation within the descending aorta.

摘要： Implantable shunt devices and methods for draining cerebrospinal fluid from a patient's subarachnoid space include a shunt having opposed first and second ends, the second end being constructed to penetrate a wall of a sigmoid, transverse, straight, or sagittal sinus of the patient, a one-way valve, a hollow passageway extending between the second end and the one-way valve such that cerebrospinal fluid can be drained through the second end and out through the valve, and a mechanism coupled to the shunt and configured to anchor the shunt at a desired location proximal to the subarachnoid space.

摘要： Mechanical circulatory assist systems and related methods produce a pulsatile blood flow in synchronization with heart activity. A mechanical circulatory assist system includes a continuous-flow pump and a controller. The continuous-flow pump is implantable in fluid communication with a left ventricle of a heart of a patient and an aorta of the patient to assist blood flow from the left ventricle to the aorta. The controller includes a sensor that generates a signal indicative of an activity of the heart. The controller is operatively connected to the continuous-flow pump and configured to operate the continuous-flow pump in an artificial pulse mode in synchronization with the activity of the heart.

摘要： Described herein are methods and devices for selectively applying fluids (particularly anesthetics) to a target tissue from within a blood vessel while minimizing the amount of fluid applied to non-target tissue. The injection catheters described herein may include an elongate body, a directional injector, and one or more holdfasts for securing the catheter before extending the injector. The methods of selectively applying anesthetic to a target structure generally include the steps of inserting an injection catheter into a body vessel, positioning the injection catheter within the body vessel near the target structure, anchoring the injection catheter before extending a directional injector from the injection catheter, and applying anesthetic from the injection catheter to the target structure.

摘要： Disclosed is a blood pump for the invasive application within a body of a patient comprising a rotor which is drivable about an axis of rotation and is radially compressible or expandable and which has a hub and at least one impeller blade fastened thereto, as well as comprising a housing which is compressible or expandable in the radial direction by an axial stretching or axial compression. Both the rotor and the housing are made expandable and compressible in as simple a manner as possible in that a control body is provided which passes through the hub in the longitudinal direction, which is freely axially displaceable relative to the hub and which is coupled to the housing on the distal side of the rotor such that it exerts pulling and/or compression forces on the housing by a movement in the longitudinal direction with respect to the housing.

摘要： Apparatus and methods are described including an impeller configured, in a radially-expanded configuration thereof, to pump a fluid by rotating. A radially expandable cage is disposed around the impeller, such that, in radially-expanded configurations of the impeller and the cage, the impeller is separated from an inner surface of the cage. The impeller is disposed within the cage such that, in response to the cage becoming radially contracted and axially elongated, the impeller radially contracts and axially elongates. Other applications are also described.
