Abstract: An apparatus for neurovascular endoluminal intervention, in particular for the treatment of ischemic stroke, is provided. The apparatus comprises a catheter (2) for insertion into the circulatory system (CS) of a patient, in order to aspirate one or several clots (C) present in the circulatory system (CS). A distal outer section (22) of the catheter (2) comprises an unexpanded state, in which the diameter (D2) of the distal outer section (22) is smaller than the diameter (D1) of a proximal outer section (21) of the catheter (2), in order to facilitate navigation of the catheter through the circulatory system, and a radially expanded state, in order to facilitate aspiration of the one or several clots (C) through the catheter (2). Furthermore, a method for applying such an apparatus is provided.

Abstract: An improved catheter is provided for removing an obstruction(s) from a blood vessel, for example, for retrieving a clot/thrombus in the neurovasculature for the treatment of stroke. The catheter has a collapsed state sufficiently small and flexible for easier delivery through challenging vasculature and also has an expanded state sufficiently sized and robust for removing the obstruction. The catheter may include a self-collapsing and expanding mechanism to transition a portion of an outer tube (e.g., a braided portion) between the collapsed and expanded states. Such mechanism may include an inner actuator tube slidable over an actuation wire to collapse a distal branched section of the actuation wire, thereby collapsing the braided portion. The catheter may also include an intermediate coiled tube for reinforcing the braided portion in the expanded state.

Abstract: A urological device includes a valve retained in a urinary catheter. The urinary catheter has a first portion that is insertable into a urethra and a second portion adapted to remain outside of the urethra when the first portion is inserted into the urethra. The valve has a closed configuration adapted to prevent urine from exiting the urinary catheter and an open configuration adapted to allow urine to flow through and exit the urinary catheter. The valve is adapted to move from the closed configuration to the open configuration in response to a hydrodynamic pressure of at least 750 mm H2O applied to the valve for at least 5 seconds.

Abstract: A method of delivering a urological device includes providing a catheter and a urological valve that can be retained within the catheter; advancing the catheter toward a bladder neck of a user; withdrawing the catheter from the user; and deploying the urological valve out of the catheter into the bladder neck or urethra of the user.

Abstract: A kit of parts includes a urological device and a catheter.

The first leaflet includes a first segment in contact with the proximal rim and a second segment in contact with the second leaflet. The first segment is curved to include a convex exterior surface and a concave interior surface of the valve. The second segment is curved to include a concave exterior surface and a convex interior surface of the valve.

Abstract: An inexpensive small-sized screen printing machine having low redundancy and high production efficiency and applicable to a dual conveying-type component mounting machine. A pair of substrate supporting tables juxtaposed in a specific direction is provided. Screen printing is alternately performed by a single print executing section in a common area which can be shared by the two substrate supporting tables. In doing so, when one substrate supporting table located at a print position among the pair of substrate supporting tables starts exiting the print position, the other substrate supporting table starts entry to the print position.
