Abstract: A suction catheter system is described with a suction extension interfaced with a guide catheter to form a continuous suction lumen extending through a portion of the guide catheter and through the suction extension. The suction extension can be positioned by tracking the suction nozzle through a vessel while moving a proximal portion of the suction extension within the lumen of the guide catheter. The suction extension can comprise a connecting section with a non-circular cross section for interfacing with the inner lumen of an engagement section of the guide catheter. Proximal fittings can include a docking manifold that can dock the connection suction of the suction extension to allow removal of the suction extension from hemostatic isolation and clearing of clots from the suction extension without further fittings such that the cleared suction extension can be efficiently reinserted for additional use.

Abstract: A system comprising: a fluid supply configured for the delivery of a fluid; a hollow body in fluid-communication with the fluid supply, the hollow body configured to be disposed between a first biological surface and a second biological surface; and a mechanism configured to control delivery of fluid from the fluid supply and through the hollow body to create separation between the first biological surface and the second biological surface.

Abstract: A catheter adapter may include a distal end, a proximal end, an inner surface extending through the distal end and the proximal end and forming a lumen, and a side port forming a side port pathway through a sidewall of the catheter adapter and in fluid communication with the lumen. The catheter assembly may include a catheter extending distally from the distal end of the catheter adapter. The catheter assembly may include a septum disposed within the lumen proximal to the side port pathway. The catheter assembly may include one or more features to facilitate flushing of the catheter assembly: a diameter of the side port may increase in a distal direction; a portion of the inner surface proximal to the catheter and distal to the septum may include multiple grooves; the side port pathway may include a non-cylindrical portion; an insert; a rotation element; and a pivot element.

Abstract: A delivery device to deliver a tubular instrument into a catheter extending distally from a catheter adapter. The delivery device may include a housing configured to couple to the catheter adapter. The delivery device may include a tubular instrument configured to insert through the catheter. The tubular instrument may include a distal end, a proximal end, and a lumen extending between the distal end and the proximal end. The distal end may include a distal tip, which may be closed. The proximal end may be secured within the housing. The tubular instrument may be configured to advance distally with respect to the housing. The delivery device may include a pressure-sensitive valve disposed at the distal tip or within the distal end. The pressure-sensitive valve may be configured to move from the closed position to an open position in response to a predetermined vacuum pressure level within the lumen.
