Abstract: Devices and methods for attaching an end of a body vessel to another body vessel are disclosed. An adhesive may be used along with a rigid member having one or more protrusions. The invention is useful in surgery, especially vascular surgery and the creation of anastomoses.

Abstract: A device (1) for making a cut in a tissue, such as a blood vessel (2), capsule and the like, includes a trocar (3), the distal end (4) of which can be placed on the tissue (2) and inside which trocar (3) a reduced pressure can be generated for holding the tissue pressed against the distal end (3) under the influence of the reduced pressure, as well as a cutting member (6) located in the trocar (3), such that the tissue (2) pressed against the distal end (4) and the cutting member (6) can be moved relative to one another to make the cut (9). A tissue support (10) is provided in the trocar (3) close to the distal end (4) thereof with which the tissue (2) that extends over the lumen of the trocar (3) can make contact under the influence of the reduced pressure inside the trocar (3).

Abstract: The invention relates to a securing device for an anastomosis connection, comprising a ring provided with two cantilever pins. The ring has an axial axis. The ring has a first transverse axis and, at right angles thereto, a second transverse axis, which are both at right angles to the axial axis. The first transverse axis divides the ring into a first half and a second half. The second transverse axis and the first transverse axis together define a transverse plane, which has a first side along which the first half of the ring extends and a second side along which the second half of the ring extends. Each cantilever pin, at in each case one attachment site, is connected to the ring by a fixed end in order, in a cantilevered manner, to extend from the ring to the other, free end of the pin. The pins extend in the same direction. The free ends of the pins are situated on the second side of the transverse plane. The attachment sites are situated on the first half of the ring.

Abstract: Invention relates to a cannula and a screw pump for use in a mechanical circulatory support device, in particular a transventricular circulatory support device. The cannula according to the present invention comprises a tubular member made of a flexible, collapsible material having a diameter between 0.5 cm and 3 cm, preferably between 1 cm and 2.5 cm. The invention also relates to an inflatable screw pump for use in circulatory support system which comprises a flexible central drive shaft and an inflatable body having a free edge defining a spiral shaped contour around the central drive shaft and an inner edge connected to the drive shaft. The Archimedes type screw pump may be used in conjunction with the flexible cannula.

Abstract: The invention provides a laser catheter for pinpointed application of laser light on the walls of intracorporal vessels, having a ring-shaped arrangement of optical fibers which surround a central longitudinal channel. A stop element at the distal region of the laser catheter widens the outer circumference, through which the optical fibers pass in beam direction. At the distal catheter tip, the fibers form a planar, ring-shaped light, exit area. The longitudinal channel of the laser catheter is provided at its distal end with a perforated member which is disposed at a short distance from the plane, ring-shaped light exit area in a direction opposite the beam direction. A second element is provided which is attached to a vessel wall as a spacer and engages, during the laser light application procedure with the element widening the circumference of the light catheter.
