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.

Medical implant

A medical implant, 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 longltudlnally open tube and having a mesh structure of intercormected strings or filaments. The implant has a tapering structure at its proximal end where the strings or filaments converge at a connection point.

Medical implant having a curlable matrix structure and method of use

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.

Micro-spiral implantation device

The invention relates to a medical implant in the form of an elongated helix wherein at least one part of the helix is preformed in such a manner that it has a secondary structure of identically sized loops which it assumes during implantation at the placement site, with said structure in turn forming at the placement site during implantation a polyhedral tertiary structure, and the polyhedron being provided with at least one additional loop.

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. In this way, a sudden breakage of the securing means () is avoided if too high a pull force is applied so that forces otherwise liberated cannot destroy the occlusion helix () or cause other damage in the blood vessel.
