A vaso-occlusive device, includes: a vaso-occlusive structure configured for implantation in an aneurysm sac, the vaso-occlusive structure having a delivery configuration when restrained within a delivery catheter and having a deployed configuration when released from the delivery catheter into the aneurysmal sac, at least a portion of the vaso-occlusive structure being composed of a AuPtW (gold-platinum-tungsten) alloy; wherein the AuPtW alloy comprises platinum within a range between 25% and 40% by weight, and wherein the AuPtW alloy comprises tungsten within a range between 0.01% and 10% by weight.

A bronchial stent includes a first branch configured to widen, open, and/or mechanically support a first airway; an obstructive portion that, when the stent is deployed in the first airway, obstructs a second airway, the second airway forming a branching connection with the first airway; and a feature proximal to the obstructive portion, the feature configured to facilitate opening of the obstructive portion.

A deployable occlusion device for filling an aneurysm. The occlusion device includes a support structure, for example a wire or otherwise elongate structure. The occlusion device also includes a mesh component having a porosity. The mesh component has a first end portion and a second end portion. The first end portion of the mesh component is attached to the support structure and the second end portion of the mesh component is a free end. The mesh component extends from the support structure.

An embolisation device (10) for promoting clot formation in a bodily lumen (L) and having a collapsed delivery configuration for delivery of the embolisation device (10) into, and retrieval of the embolisation device (10) from, the bodily lumen (L) and an expanded deployed configuration for anchoring the embolisation device (10) in the bodily lumen (L). The embolisation device (10) comprises a tubular cage (20) having a collapsed delivery configuration and an expanded deployed configuration. The embolisation device further comprises an embolisation member (30) disposed in the tubular cage (20), the embolisation member (30) comprising a stem (31) and a plurality of flexible bristles (32) extending outwardly from the stem, the plurality of flexible bristles having a collapsed delivery configuration and an expanded deployed configuration. The embolisation device (10) is configured such that as the tubular cage (20) is transitioned from its expanded deployed configuration to its collapsed delivery configuration the plurality of flexible bristles (32) is urged by the tubular cage (20) from the expanded deployed configuration of the flexible bristles (32) to the collapsed delivery configuration of the flexible bristles (32).

An embolisation device (100) for promoting clot formation in a bodily lumen (170), comprising a stem (110) and a plurality of flexible bristles (120) extending outwardly from the stem, the bristles having a contracted delivery configuration and an expanded deployed configuration in which the bristles extend at least radially outwardly from the stem to anchor the device in the lumen. The embolisation device comprises a flow restrictor configured to restrict flow through the bodily lumen. The flow restrictor comprises: a membrane support (135) having a contracted delivery configuration and an expanded deployed configuration and comprising a self-expanding mesh extending at least radially outwardly from the stem; and an occluding membrane (130) mounted on the membrane support (135). The occlusion rate of the occluding mesh membrane is greater than that of the membrane support. The flow restrictor is attached to the stem at a first longitudinal end, the flow restrictor further comprising an open second longitudinal end. The occluding membrane is configured to restrict flow through the lumen when the device is deployed and the membrane support is in the expanded deployed configuration.

There is provided an implant system comprising: a delivery wire assembly having a female detachment mechanism component; and an implant having a male detachment mechanism component, wherein the female detachment mechanism component comprises a coil configured to receive the male detachment mechanism component such that the male detachment mechanism component is attachable to the female detachment mechanism component.

A device for occluding flow of materials is formed as a simple structure permitting a compact delivery configuration which may shift to an expanded deployment configuration. The device has at least one expandable portion formed of a plurality of elongated longitudinally extending frame elements. The frame elements may be spaced apart to define spaces therebetween, and a flexible occlusive material may be provided to block flow of material through such spaces. A flexible occlusive material may form one of two expandable portions of the device without the need for frame elements.

Aortic occlusion and embolic protection devices include radially expandable and collapsible proximal and distal end portions, such as annular self-expanding stents or frames, that are configured to radially expand within an aorta to secure the device within the aorta. The devices can also include a catheter extending axially between the distal end portion and the proximal end portion and a porous covering, or filter, positioned around the catheter and between the proximal end portion and the distal end portion and configured to filter emboli from blood flowing into upper-body arteries. The device can further include a one-way valve positioned at or adjacent to the distal end portion of the device and configured to restrict retrograde blood flow through the device toward the heart.

A bristle device for delivery into a body lumen comprises a longitudinally extending stem 1 and a plurality of bristles extending generally outwardly from the stem for anchoring the device in a body lumen. There may be at least two bristle segments and in some cases there are flexible sections between the segments. The flexible sections articulate to enable the device to pass through a catheter placed in a tortuous anatomy or to be deployed in a curved vessel, or across a bifurcation. In some cases at least some of the bristle segments are spaced-apart to accommodate bending of the bristles.

Devices and methods are described for occluding the left atrial appendage (LAA) to exclude the LAA from blood flow to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. An implant is delivered via transcatheter delivery into the LAA. The implant includes a conformable structure comprising a foam body and internal support. The support includes anchors that penetrate the foam body and anchor the implant to the walls of the LAA. The implant provides compliance such that it conforms to the native configuration of the LAA.
