The present invention relates to an occlusion device (1) consisting of a braiding (2) of thin wires or threads (4) which is given a suitable form in a molding and heat treatment procedure. The occlusion device (1) has a proximal retention area (6) and a distal retention area (8), whereby the ends of the wires or threads (4) converge into a holder (5) in distal retention area (8). A cylindrical crosspiece (10) is furthermore disposed between the proximal and distal retention areas (6, 8). With the objective of providing an occlusion device which positions as flat as possible against the septum at the proximal side of a septal defect in the inserted state, the invention provides for the proximal retention area (6) of the braiding (2) to exhibit a completely closed proximal wall (112) disposed with a continuous surface at the proximal end of the occlusion device (1) which forms the proximal end (12) of said occlusion device (1).

Transfer system cooperating with a machine for producing tobacco and filter product rods having a rod receiving unit, a cutting head, and a control system. The machine enables adjustment of the length of the produced rods, whereby the rod receiving unit of the transfer system is synchronized with the cutting head by the control system. The transfer system is situated between the machine for producing rods and a machine for further processing or transmitting the rods. A rejection unit is provided for rejecting the rods outside the transfer system during the synchronization of the rod receiving unit of the transfer system with the cutting head after a new length is entered into the control system. The rejection unit is located between the cutting head of the machine and the rod receiving unit.

An occlusion device and a production process for it are described. The occlusion device consists of a mesh or braiding of at least one wire or thread wherein the occlusion device has been given a suitable design using a reshaping and/or heat-treatment process, is self-expandable, and is configured for secure anchoring in an atrial appendage of the left or right atrium of a heart. The occlusion device comprises a proximal retention region on a proximal end of the occlusion device a distal retention region and a central region between the proximal retention region and said distal retention region and wherein the occlusion device has a closed distal end without a holder, and wherein the occlusion device is at least partly of essentially spherical form, and hollow.

A detection device and method for monitoring infestation by insects such as bed bugs is provided. A suitable device comprises a pair of plates separated by an internal spacing sized to permit entry into the detection device by one or more insects. Also disclosed is a method for readily detecting insects such as bed bugs in a multiple areas such as in multiple hotel rooms, areas where animals are housed, or the like.
摘要:
The invention relates to an anchoring system for heart valve prostheses which can be implanted by introduction via the aorta without any major surgical operation. With the heart valve prosthesis according to the invention it shall be achieved that this can be safely and quickly guided through the aorta toward the heart, and can be fixed there. With this, hook-shaped elements are secured to the commissures of the heart valve prosthesis the hooks of which are guided in an outward direction through the heart valve prosthesis material.

A device for multifoaming expandable plastics, such as, for instance, EPS, EPE, EPP or polymer mixtures, includes at least one storage or supply assembly and a foaming vessel for the discontinuous or batchwise afterfoaming of the prefoamed expandable plastics, whereby precisely adjustable bulk densities are attainable in an afterfoaming procedure while observing tight environmental conditions.
摘要:
A process for multifoaming expendable plastics, such as, for instance, EPS, EPE, EPP or polymer mixtures, wherein prefoaming is effected in a first step and after foaming of already prefoamed material is effected in at least one further step. The process also provides that discontinuous or batchwise foaming is carried out as final afterfoaming.
