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: The invention is directed to a laser catheter (1) for bypass surgery, wherein the distal part (2) of the catheter (1) is provided with: a tubular arrangement (3) of optical fibers (4) having distal ends (5) defining a ring-shaped light emergence surface (6) for emitting a tubular bundle of light beams in the distal direction (D) of the catheter (1); and a stop surface (7) extending around the tubular arrangement (3) of optical fibers (4) and facing in the distal direction (D), the stop surface (7) being arranged at a distance (A) proximally from the light emergence surface (6). The light emergence surface (6) slants at a slanting angle (?) in the range of [20°, 60°] with respect to the longitudinal axis (8) of the catheter (1). The invention further relates to an assembly comprising such a catheter.

Abstract: The invention relates to an assembly comprising on the one hand a graft vessel and on the other hand an anastomosis has connector. The connector comprises a ring and two pins. Each pin has a free end and a fixed end connected to the ring. The pins extend, viewed from the fixed end towards the free end, next to and set apart from each other. Each pin has an overlap section where the pin, viewed in axial direction of the ring, overlaps the plane bounded by the outer contour of the ring. The axial axis of the ring extends transverse to the wall of the graft vessel. The connector is attached to the graft vessel and the ring lies, with its full circumference, against the wall of the graft vessel. The invention further relates to a method of providing such an assembly and a method of attaching such an assembly to a recipient vessel.

Abstract: The invention concerns an assembly for by-pass surgery. The assembly comprises a laser catheter. The laser catheter comprises: a tubular arrangement of optical fibres having distal ends defining a ring-shaped emitting surface arranged for emitting a tubular bundle of laser beams in a distal direction of the catheter; and a gripper for gripping tissue inside the tubular bundle of laser beams, having a gripping end defining the location where gripped tissue is held, the gripping end being arranged inside the tubular bundle and proximally from the emitting surface. The distance between the emitting surface and the gripping end is at least 1 mm.

Abstract: The invention relates to a device for producing an ETS anastomosis connection and/or a STS anastomosis connection, comprising a ring (10) with two pins (11). Each pin has a free end (12) and a fixed end (13) which is secured to the ring; the pins extending, viewed from the fixed end toward the free end, next to and set apart from each other in the same direction. The pins each have a clamping section where the pin extends, in a first position, parallel to and along said ring from a first side of the ring to a second side of the ring that is situated diametrically opposite said first side in order to be able to clamp tissue of the wall of the receiving vessel between the ring and the clamping sections. The clamping sections of the pins are, in a second position, at an angle with respect to the plane defined by the ring in order to form, together with the ring, a jaw which widens, viewed in the direction from the fixed ends toward the free ends.

Abstract: A catheter system is provided comprising a laser catheter with a fibre bundle of optical fibres emitting a light beam in the distal direction of the catheter and a laser apparatus, comprising one or more lasers for supplying light to the optical fibres. The catheter system is preset or adjusted for emitting a pulsating light beam with an ablation power of at least 40 mJ/mm2 per pulse at the location of a light emitting surface. A method for preparing such a catheter system is provided comprising the step of a) measuring said ablation power at the location of the light emitting surface; b) comparing the measured ablation power with a predefmed power value requirement; c) in case the measured ablation power is different from the predefmed power value requirement, adjusting the ablation power of the pulsating light beam to meet the predefined power value requirement.

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: The invention is directed to a laser catheter (1) for bypass surgery, wherein the distal part (2) of the catheter (1) is provided with: a tubular arrangement (3) of optical fibres (4) having distal ends (5) defining a ring-shaped light emergence surface (6) for emitting a tubular bundle of light beams in the distal direction (D) of the catheter (1); and a stop surface (7) extending around the tubular arrangement (3) of optical fibres (4) and facing in the distal direction (D), the stop surface (7) being arranged at a distance (A) proximally from the light emergence surface (6). The light emergence surface (6) slants at a slanting angle (?) in the range of [20°, 60°] with respect to the longitudinal axis (8) of the catheter (1). The invention further relates to an assembly comprising such a catheter.
