  • Patent number: 11426293
    Abstract: A medical having a proximal and a distal end, that is preformed to assume a superimposed structure at an implantation site but can be made to take on a volume-reduced form making it possible to introduce it by means of a micro-catheter and a guide wire arranged at the proximal end, with the implant in its superimposed structure assuming the form of a longitudinally open tube and having a mesh structure of interconnected strings or filaments. The implant has a tapering structure at its proximal end where the strings or filaments converge at a connection point.

  • Patent number: 9198665
    Abstract: The invention relates to a device for the implantation of microcoils into body cavities and blood vessels, in particular aneurysms, with said microcoils comprising wires forming a plurality of windings, at least one microcoil serving as occlusion helix for the occlusion of the body cavity or blood vessel, and the device consisting of a catheter, one or several microcoils movably arranged in longitudinal direction within the catheter and at least one securing means passing at least partially through the lumen of the occlusion helix, with said securing means being fixed in its end areas inside the microcoils. Such a fixation of the securing means is achieved in at least one end area by providing a frictional connection with the microcoil in such a manner that this connection is detachable from the microcoil when a certain tensile force acting on the securing means is exceeded.

  • Patent number: 5702403
    Abstract: The invention is directed to an epilating appliance for the removal of human body hairs which is adapted to be held in a user's hand and guided over the sections of the skin to be treated. The epilating appliance includes a cylinder rotary about a center axis, the cylinder periphery being formed by at least one group of relatively fixed blades and at least one group Of relatively movable gripping elements. The blades and the gripping elements of a group are arranged adjacent to each other at least in pairs, and the groups are in successive arrangement on the cylinder when viewed in a direction of rotation of the cylinder. The gripping elements are adapted to approach each other and recede from each other at least in pairs, closing and, respectively, opening a gripping aperture in the process. Adjacent blades combine to form a groove of a width tapering in wedge or funnel shape, with at least one groove end section of reduced groove width being associated with one gripping aperture each.
