Described herein are methods using mechanical inverting tube apparatuses to remove clot (e.g., thrombectomy), the apparatuses including an inversion support catheter having an expandable funnel-shaped distal end, and a flexible tube that can be continuously rolled over the funnel-shaped distal end and invert into the inner lumen of the inversion support catheter.

A lumen extension member is provided for a catheter having a catheter body and an elongate electrode coupled to the catheter body. The elongate electrode defines an electrode lumen extending therethrough. The lumen extension member is positioned within the electrode lumen and is coupled to the catheter body. The lumen extension member includes a tubular member including a sidewall and at least one opening that extends through the sidewall.

Methods, systems, and devices for accessing tissue outside a bronchus and marking the location of a biopsy are provided. The method includes loading a navigation plan into a navigation system with the navigation plan including a CT volume generated from a plurality of CT images, inserting an extended working channel (EWC) including a location sensor into a patient's airways, registering a sensed location of the EWC with the CT volume of the navigation plan, and selecting a target in the navigation plan located outside the periphery of a patient's airways. The method further includes navigating the EWC and location sensor proximate the target, inserting a piercing catheter into the EWC, piercing through an airway wall to reach the target, storing a position of the location sensor in the navigation system as a biopsy location, and performing a biopsy at the stored biopsy location.

An elongated catheter assembly defines a catheter lumen configured to receive the distal guidewire section of the guidewire, and also defines an axial portal and a radial portal. A guidewire deflector is mounted to the elongated catheter assembly. The guidewire deflector is configured to selectively deflect urged axial movement of the distal guidewire section of the guidewire away from the axial portal and radially toward the radial portal.

The medical device may comprise an elongate body having a proximal portion, a distal portion, and defining a lumen therethrough. Also, the medical device may include an expandable element coupled to the distal portion of the elongate body and in fluid communication with the lumen. The expandable element may define a first end and a second end, the second end being proximal to the first end. The medical device may further include a cannula surrounding at least a portion of the elongate body and the cannula may define a proximal end and a distal end. The distal end of the cannula may be disposed proximal and adjacent to the second end of the expandable element. An outer dimctcr diameter of the cannula may be substantially equal to or lesser than an outer diameter of the expandable element when inflated. The medical device may be maneuvered through a patient's body.

A medical device includes: a tube through which fluid flows; a handle part coupled to a proximal end part of the tube; an electrode tip coupled to a distal end part of the tube; a fluid injection part configured to inject fluid into the tube; one or more openings formed in the tube; and a guide member disposed in the tube, and having an inclined part to guide the direction of the fluid sprayed out through the opening.

A shunt for draining fluid including a first catheter, an electronic pump fluidly coupled to the first catheter, a manual pump fluidly coupled to the electronic pump, a second catheter fluidly coupled to the manual pump. During a drainage operation, the shunt arranged and configured such that a fluid is passively pressure-driven through the shunt, and the electronic pump is arranged to prevent blockages within the shunt by flowing a bolus of the fluid through the shunt. Additionally, the manual pump is arranged to prevent blockages within the shunt by flowing a bolus of the fluid through the shunt in the event that the electronic pump cannot produce a bolus of the fluid.

In some examples, a system includes a catheter comprising an elongated shaft defining a lumen, and a tether assembly. The tether assembly may include an elongate body, a tether head assembly attached to a distal end of the elongate body, where the tether head assembly includes an attachment mechanism configured to releasably attach to an attachment member of a medical device, and a positioning element fixedly positioned over the elongate body and configured to align the attachment mechanism with the attachment member when the tether head assembly is extended distally out of the lumen. The positioning element may include a distal end, a proximal end, and a length between the distal end and proximal end that is less than a length of the elongate body. The tether head assembly, elongate body, and positioning element may be movable within the lumen of the elongated shaft.

Methods and devices for trans-jugular carotid access are disclosed. Methods within the scope of this disclosure include methods of trans-jugular carotid access originating in the leg of a patient or other location remote to the jugular vein and carotid artery and methods originating at the neck of a patient. Devices used in connection with the disclosed methods may comprise access catheters, lumens, and stylets.
