A method of deploying a surgical fastener into a patient by introducing the fastener into a body of a patient while the fastener is in a first shape having a first loop with a back span and an original size and shape. The method then involves moving end segments of the fastener away from each other substantially along an entire length thereof while keeping the back span in substantially its original size and shape. The method then involves forming the fastener into a second loop having a width greater than a width of the first loop.

Implants, implant systems, and methods for treatment of mitral valve regurgitation and other valve diseases generally include a coaptation assist body which remains within the blood flow path as the leaflets of the valve move, the valve bodies often being relatively thin, elongate (along the blood flow path), and / or conformable structures which extend laterally from commissure to commissure, allowing the native leaflets to engage and seal against the large, opposed surfaces on either side of the valve body during the heart cycle phase when the ventricle contracts to empty that chamber of blood, and allows blood to pass around the valve body so that blood flows from the atrium to the ventricle during the filling phase of the heart cycle. Separate deployment of independent anchors near each of the commissures may facilitate positioning and support of an exemplary triangular valve body, with a third anchor being deployed in the ventricle. An outer surface of the valve body may accommodate tissue ingrowth or endothelialization, while a fluid-absorbing matrix can swell after introduction into the heart. The valve body shape may be selected after an anchor has been deployed, and catheter-based deployment systems may have a desirable low profile.

Everting filter devices and methods for using the devices, including using the devices as intra-vascular filters to filter thrombus, emboli, and plaque fragments from blood vessels. The filter devices include a filter body nominally tubular in shape and having a large proximal opening. The filter body can extend from a proximal first end region distally over the non-everted exterior surface of the filter, further extending distally to a distal-most region, then converging inwardly and extending proximally toward the filter second end region, forming a distal everted cavity. The degree of eversion of the filter can be controlled by varying the distance between the filter first end region near the proximal opening and the closed second end region. Bringing the filter first and second end regions closer together can bring filter material previously on the non-everted filter exterior to occupy the distal-most region. The everting process can also bring filter material previously in the distal-most position further into the distal everted cavity. The filter devices can be used to remove filtrate from body vessels, with the filtrate eventually occluding the distal-most region. The filter can then be further everted, bringing fresh, unoccluded filter material into place to provide additional filter capacity. Some everting filters have the capability of switching between occluding and filtering modes of operation, thereby allowing a treating physician to postpone the decision to use filtering or occluding devices until well after insertion of the device into the patient's body.

Expandable emboli filter and thrombectomy devices adapted for use with microcatheters to remove debris from blood vessels. The devices embody expanded profiles that span the entirety of various sized target vessels and thus are particularly effective in the engagement of debris found in vessels.

A walker apparatus comprised of a first front support leg assembly, a second front support leg assembly, a first sliding joint, a second sliding joint, a central hinge joint, a first rear support leg assembly, a second rear support leg assembly, a first support member, a second support member, a front leg collapsing assembly, and a rear leg collapsing assembly. The walker apparatus is adapted to be is collapsed to a compact shape in a continuous collapsing motion.

A directional microphone system comprises two membranes that, on the one hand, are respectively acoustically connected via an air volume with one of two spatially separate sound entrance ports, and on the other hand are acoustically coupled with one another via a third air volume, as well as an output generator configured to generate at least one output signal of the directional microphone from the vibration of one of the two membranes.

An axial flow type cooling fan, comprising an upper casing, a lower casing, a rotor assembly, and a driving unit. The lower casing and the upper casing enclose an inner space. The rotor assembly is housed in the inner space and performs a rotational movement. The rotor assembly further comprises a plurality of blades, attached to a central shaft and having a peripheral ring, from which a peripheral rim extends outward. The driving unit has electric coils on the upper or lower casings and permanent magnets on the peripheral rim, causing the rotational movement of said rotor assembly. By the arrangement of these structural parts, an increased area of air flow and consequently increased air flow are attained, while drag and noise are reduced.

An electrode support structure assembly is provided comprising an electrode support structure including a plurality of splines. Each of the plurality of splines can have a proximal end portion and a distal end portion. The assembly further comprises a first element defining an axis and comprising an outer surface. The outer surface comprises a plurality of slots configured to receive the distal end portion of each of the plurality of splines. The first element is configured such that the distal end portion of each of the plurality of splines may move with respect to each slot. In accordance with some embodiments, the distal end portion of each of the plurality of splines comprises a section configured for engagement with the first element, wherein the section comprises a shoulder.
