A clot capture module can include a housing, a chamber inside the housing, a window, and a filter. The window permits visual inspection of a clot inside the chamber. The clot can access the chamber via an incoming flow path configured to direct blood from an aspiration catheter to an upstream surface of the filter. An aspiration control valve can block the flow of incoming aspirated blood until actuated to permit inflow of aspirated blood. An outgoing flow path can direct blood from a downstream surface of the filter to a remote vacuum canister.

An introducer tool for use with a vascular entryway system and method. While a radially self-expanding distal section of an aspiration catheter is in a radially non-compressed state, an aspiration catheter is pre-assembled into a flared proximal section of the introducer tool. Together as a single unit, the introducer tool with the aspiration catheter pre-assembled therein is introduced into a hemostasis valve and a tapered guide sheath luer. The aspiration catheter is pushed through the introducer tool. While traversing the compressing section of the lumen of the shaft of the introducer tool and/or the tapered inner profile of a tapered guide sheath luer, the radially self-expanding distal section of the aspiration catheter is radially compressed to be receivable in a lumen of a guide sheath catheter. While the radially self-expanding distal section is radially compressed, the aspiration catheter is slid into the lumen of the guide sheath catheter.

An inserter for guiding a device through a hemostasis valve. The inserter comprises an elongate tubular body, a concave landing zone, and an axially extending slit. The elongate body tubular body of the inserter partially defines a central lumen. A method a of passing a device through a valve comprises the steps of providing an inserter having a tubular body with a split sidewall, advancing the tubular body through a valve, advancing a device through the tubular body and beyond the valve and retracting the tubular body so that the device escapes laterally from the tubular body through the split sidewall, leaving the device in place across the valve.

A thrombus engagement tool having a flexible shaft, a clot engagement tip, and a handle. The engagement tip may include one or more radially outwardly extending structures such as a helical thread. The helical thread can be advanced through a catheter to engage a clot. The handle may be configured to be rotated by hand. When the handle is rotated, the helical thread of the engagement tip can rotate in the same direction thereby allowing the helical threat to engage the clot. The helical thread can wrap around the flexible shaft at least about one, two, or four or more full revolutions, but in some cases no more than about ten or no more than about six revolutions.

A valve body and a medical instrument provided with the valve body can stably maintain sealing performance for preventing air/blood leakage while maintaining a smooth insertion feeling even when various types of medical devices are repeatedly inserted and removed. The valve body includes a main body portion having oppositely facing first and second surfaces, an outer peripheral surface extending between the first and second surfaces, and an insertion portion having an inner surface defining a gap that allows insertion of a medical device and formed at least on the first surface. The main body portion contains a self-repairing material that allows self-repairing damage resulting from contact with the medical device. At least part of the inner surface of the insertion portion is provided with a coating layer that prevents the gap from being closed by self-repair when portions of the inner surface of the insertion portion contact each other.

A catheter assembly is disclosed that includes a catheter adapter having a port disposed on its sidewall. A valve is coupled to the port to seal the opening in the port.

A catheter assembly may include a catheter adapter, which may include a distal end, a proximal end, and a lumen extending therethrough. The catheter assembly may also include a septum slidably disposed within the lumen. The septum may include a distal end, a proximal end, and a barrier disposed between the distal end of the septum and the proximal end of the septum. The barrier may divide an interior of the septum into a distal cavity and a proximal cavity. A distal face of the barrier may include a protrusion. The barrier may include a slit extending through the protrusion for selectively opening fluid communication between the distal cavity and the proximal cavity.
