An implantable vessel filter device having a plurality of radially expandable legs with hooks, and a center-post configured to prevent entanglement of the radially expandable legs when they are compressed against the center-post. In one variation, the filter device includes a first set of legs, forming a first filter basket in the expanded position, and a second set of legs, forming a second filter basket distal to the first filter in the expanded position. Hooks may be provided on the second set of legs to prevent migration of the filter along the vessel after the filter is deployed. Grooves may be provided along the shaft of the center-post to receive the hooks and prevent the hooks from interlocking when the legs of the filter are compressed along the center-post.

A modification to allow delivery of a two port medical flow restrictor over a guidewire, and a means to mechanically collapse the new device. A thin walled, foil-like shell, is compacted for delivery. The invention includes the device, delivery assemblies, and methods of placing, and using, the device. A device with an aneurysm lobe and an artery lobe self-aligns its waist at the neck of an aneurysm as the device shell is pressure expanded. Mechanical force collapses both the aneurysm lobe and the artery lobe, captivating the neck of the aneurysm and securing the device. The device works for aneurysms at bifurcations and aneurysms near side-branch arteries. The device, unlike endovascular coiling, excludes the weak neck of the aneurysm from circulation, while leaving the aneurysm relatively empty. Unlike stent-based exclusion, the device does not block perforator arteries. This exclusion device can also limit flow through body lumens or orifices.

Devices and methods are described herein for implanting a connector to provide an anastomotic connection at a graft / host vessel junction.

The invention discloses an arm support supporting device which is used for supporting an arm support (2) of a construction vehicle. The arm support supporting device comprises a main oil cylinder (3) for supporting the arm support (2) and an auxiliary oil cylinder (4), wherein a preset distance is reserved between the main oil cylinder (3) and the auxiliary oil cylinder (4); and the arm support (2) is lapped on the upper surface of the auxiliary oil cylinder (4). The arm support is commonly supported by the auxiliary oil cylinder and the main oil cylinder, thus the pressure of the main oil cylinder is effectively reduced; the problem that the variable amplitude torque is insufficient at the initial stage of variable amplitude of the arm support is effectively improved; the operation capability of the variable amplitude of the construction vehicle can be improved; the weight of the main oil cylinder can be reduced; and the arrangement property of the construction vehicle is improved; the invention provides a novel structural arrangement mode and a solution for large-scale development of the construction vehicle and the arm support thereof; in addition, the buffer during variable amplitude drop of the arm support can be realized, and thus the reliability of the construction vehicle is improved. The invention further provides the construction vehicle comprising the arm support supporting device. The reliability of the construction vehicle is improved.

Delivery systems, and methods using the same, having an ultrasound viewing window for improved imaging and a needle for ablation treatment of target tissues. In an embodiment, the target tissue is a fibroid within a female's uterus. In an embodiment, the delivery system includes a rigid shaft having a proximal end, a distal end, and an axial passage extending through the rigid shaft. In an embodiment, the axial passage is configured for removably receiving the ultrasound imaging insert having an ultrasound array disposed a distal portion.

The invention discloses a server remote restart method based on a mobile phone APP and encrypted short messages. The method uses a mobile phone APP program, and through the encrypted short messages and adding timestamp in the short messages, encryption communication and information validity verification are performed on mobile phone clients, a front-end processor short message processing system, and a server daemon process, and the encrypted short message sent out by a mobile phone end is embedded with an operating instruction, so as to perform remote restart operation on a server. The method can be integrated with authority management of an enterprise information system, and safely and conveniently perform remote restart on servers of an enterprise intranet.
