  • Publication number: 20210361305
    Abstract: Embodiments disclosed herein relate to an aspiration catheter comprising a catheter body that can have a first end and a second end and an aspiration lumen extending through the catheter body. The aspiration lumen can have an aspiration opening located in a distal portion of the aspiration catheter. The catheter can have an assistive jet element extending through a wall of the aspiration lumen. The assistive jet element can have an assistive jet channel. The assistive jet element can be adaptable to draw blood through the assistive jet element from a location outside of the catheter body adjacent to the assistive jet element and into the aspiration lumen when suction is applied to the aspiration lumen and can be configured to break apart a thrombus or obstruction in the aspiration lumen.

  • Publication number: 20210209968
    Abstract: A human body simulation device includes an aorta model that simulates an aorta, and a biological model that simulates a part of a human body and has a partial blood vessel model simulating a part of blood vessels. The aorta model includes a biological model connecting portion that attachably/detachably connects the biological model in a state where an inner cavity of the aorta model and an inner cavity of the partial blood vessel model are in communication with each other, and a fluid feeding portion connecting portion that connects a fluid feeding portion for feeding a fluid into the inner cavities.

  • Publication number: 20210128157
    Abstract: A ligation device includes a main body and a first ligation ring. The main body has a cylindrical shape. The main body is configured to be attached to an endoscope and to be located on a distal end portion of the endoscope. The main body includes a distal end portion configured to project from a distal end of the endoscope in a longitudinal direction of the main body and includes a first fluid feeding passage with a first opening that opens on a distal end face or an outer peripheral face of the distal end portion of the main body. The first ligation ring is attached to the distal end portion of the main body so as to obstruct the first opening.

  • Publication number: 20130046202
    Abstract: A guidewire includes a core shaft, a hollow coil body, and a hollow resin body. The core shaft includes a distal portion, a proximal portion, and a center portion that is sandwiched between the distal portion and the proximal portion. The hollow coil body covers the distal portion when the distal portion is enclosed within the hollow coil body. The hollow resin body covers the center portion when the center portion is enclosed within the hollow resin body. The center portion has a tapered shape such that the diameter of the center portion decreases from a proximal end portion side of the center portion toward a distal end portion side of the center portion, and a rigidity of the hollow resin body is higher than a rigidity of the hollow coil body.
