20080243223 | Device for affixing of tubular medical accessory to a body passage - A device for affixing a tubular medical accessory to a wall of a body passage is disclosed. The said device comprises a handle portion, a barrel portion and a working head portion, said barrel portion is fitted with a pushing rod displaceable along the barrel portion upon actuating the handle portion. The working head portion is fitted with a plurality of wings and levers and said wings are preloaded with a plurality of staples. Upon initial displacement of the pushing rod in a distal direction the wings are swiveled towards the medical accessory such that they abut it and stretch it together with the body passage in a radial direction. Upon still further displacement of the pushing rod the levers are swiveled and cause the staples to exit from the wings such that the staples pierce the accessory and the wall of the body passage and affix the accessory to the body passage. | 10-02-2008 |
20090105804 | Medical implanting devices provided with anti-trombogenic coating and method for obtaining of such coating - A medical implantable device for deployment within a vessel of a mammal patient is disclosed. The device has at least one surface, which might come in contact with blood, said at least one surface being coated by a biocompatible anti-trombogenic coating. The anti-trombogenic coating being presented in a thermodynamic non-equilibrium labile state defined by a surface energy favorable for immobilizing of albumen thereon while preventing adhesion of thrombogenic proteins thereto. | 04-23-2009 |
20090132021 | APPARATUS AND METHOD FOR DELIVERY, SPREADING AND DOUBLE-ENDED FIXATION OF VASCULAR GRAFTS - The present invention relates to medical techniques, more particularly to methods and apparatus for delivery and double-ended fixation of vascular prosthesis—grafts or stent-grafts to blood vessel walls in direction from inside these vessels to their outer surface. The apparatus comprises a tubular body with two expandable working heads at the free end, means for securing thereon the prosthesis end. The heads have eight cartridges each, and each of these cartridges is provided with one basic and one standby fastener means, substantially U-shaped staples. A control mechanism is provided consisting of two control modules joined together. The apparatus is also provided with means for positioning inside a blood vessel. There is further proposed a method for delivery and double-ended fixation of an endovascular prosthesis to a blood vessel wall. | 05-21-2009 |
20090240262 | Device for affixing prosthesis to a vessel - Embodiments of the present invention are directed to devices, systems and methods (both in operation of the devices and systems, and methods of treatment on a mammal) for affixing a prosthesis, e.g. graft to a first end and to a second end of a vessel is described. Such embodiments include a device which may comprise a rear handle portion, a frontal working portion and an intermediate barrel portion. The working portion may be loaded with a first plurality of staples and with a second plurality of staples. The barrel portion is preferable adapted to carry the graft thereon and the device is preferably provided with a pushing rod which may be displaceable along the barrel portion so as to cause protrusion of the first and the second plurality of staples towards the first end and towards the second end of the vessel respectively. | 09-24-2009 |

20100080239 | TECHNIQUE FOR COMBATING LOOPS IN COMMUNICATION NETWORK - Technology for combating loops in multi-domain networks, by assigning to network domains categories, at least such as “high/trusted” and “low/less trusted”, and by making a decision about relearning Forwarding Information Base FIB of any edge node interconnecting different network domains, utilizing the assigned categories. | 04-01-2010 |
20110280242 | TECHNOLOGY FOR FLUSHING AND RELEARNING MAC ADDRESSES IN TELECOMMUNICATION NETWORKS - A technique for performing a flushing process at a port of a network switch, where the flushing process comprises a flooding operation and an operation of relearning MAC addresses. In the method, these two operations are made independent, and the operation of relearning MAC addresses is started before termination of the flooding operation. An operation of forwarding packets to the relearned MAC addresses can be started before termination of the flooding operation. | 11-17-2011 |
20120257539 | METHOD FOR MAC ADDRESSES WITHDRAWAL IN TELECOMMUNICATION NETWORKS - A rationalized MAC withdrawal method for a multi-domain communication network, where at least one access node interconnects a remote node with two or more access networks. The method allows flushing, both in the access nodes and in the remote node, only MAC addresses being related to a specific access networks where a topological change has taken place, without affecting other access networks connected to the same access node. | 10-11-2012 |
