A ureteroscope system includes a handle; an elongated shaft extends from the handle to a distal end and includes a working channel which is opened at the distal end; an external member extends from a proximal end to a distal end and is coupled to the shaft, the member includes a hub and a tube defining a first external channel; and a coupling mechanism defines first and second tubes and is coupled the distal end of the member to the distal end of the shaft. The first tube defines a first lumen and the second tube defines a second lumen which is sized and shaped to receive a distal end of the member. A proximal portion of the first tube is sized and shaped to be inserted into a distal portion of the shaft such that the first lumen is opened to the working channel.

Techniques and devices for removal of clot/material from body passages utilize a main carrying wire, a main elongated sleeve element braided from a plurality of wires to form a proximal tubular section having a proximal opening and a funnel-shaped distal section tapering distally onto a distal end portion of the main carrying wire for rigid attachment thereto, a deformable ring element coupled to the proximal opening of the main elongated braided sleeve element and configured for changing the proximal opening from a normally opened state to an at least partially closed state, and a control wire rigidly coupled to the deformable ring element for manipulating the proximal opening of the main elongated braided sleeve element between its normally opened and at least partially closed states for secure removal of the captured target clot from the blood vessel.

Disclosed is a thrombectomy stent system, comprising a thrombectomy stent, wherein the thrombectomy stent is roll-shaped, and the cross section of the thrombectomy stent is of an open-ring structure. Disclosed is a thrombectomy device, comprising the thrombectomy stent, wherein the thrombectomy stent is provided with a developing element that can accurately display the expansion state of the thrombectomy stent during thrombectomy and the specific position of the thrombectomy stent so as to determine the situation of the thrombectomy stent being fused with a blood vessel. Disclosed is a thrombectomy device system, comprising the thrombectomy stent and a push rod, wherein a proximal end of the thrombectomy stent is connected to the push rod, and the proximal end of the thrombectomy stent or the push rod is connected to a catching member; and the catching member is configured to receive the thrombectomy stent. The catching member can effectively catch a thrombus that is detached during the thrombectomy.

Provided herein are methods and systems for the removal of anatomical occlusions, and an occlusion removal device comprising a first body adapted to be mounted to a delivery wire and releasably engaged to the delivery wire, wherein while engaged the first body remains fixed on the delivery wire and upon release moves axially along the delivery wire, and a second body adapted to be mounted to the delivery wire. A first proximal body may be oriented proximally to a second distal body. The proximal body and the distal body may be adapted to expand upon exiting a delivery catheter. The proximal body may be releasably engaged by a mechanically breakable connection or an electrolytically or heat disconnectable connection, the electrolytically disconnectable connection being broken upon an application of electric current to the electrolytically disconnectable connection.

Mechanical thrombectomy apparatuses including an inverting, rolling conveyor region (“tractor”) at the distal end that are configured to grab and remove thrombus material. In particular, described herein are mechanical thrombectomy apparatuses that are adapted to prevent premature deployment of the tractor, e.g., by including a tractor hold (e.g., a housing, a lock, a clamp, etc.) or the like to secure the outer end of the tractor against and/or relative to the elongate inversion support.
