An implant (1) for the treatment of aneurysms (11), wherein the implant (1) has an elongated configuration navigable via a microcatheter (12) and a secondary configuration which it assumes upon release from the microcatheter (12). The implant (1) forms an open, unrolled structure (2) extending from proximal to distal, said implant being built up of a plurality of struts (3) forming adjacent cells (4), and with at least a part of said cells (4) being provided with membranes (6) filling the cells (4), and with the secondary structure comprising an at least partial rolling up of the open, unrolled structure (2) axially and radially relative to the longitudinal axis of the implant (1) and resulting in the formation of a spherical structure. The implant (1) proposed by the invention is suitable to adapt to the inner wall of an aneurysm (11) and to fill an aneurysm (11) almost completely.

This invention is an intrasaccular aneurysm occlusion device comprising: a net or mesh with a self-expanding resilient proximal portion (which is deployed close to the aneurysm neck) and an expandable flexible distal portion (which is deployed close to the aneurysm dome); and a “string of pearls” of embolic members which are inserted into the net or mesh.

A vascular remodeling device has a plurality of sections, sized for deployment in a blood vessel, that is radially expandable from a collapsed state to an expanded state. Each section has a plurality of interconnected struts that define a waist, a proximal face, and a distal face. Each face comprises (i) a plurality of distal strut portions extending proximally from a distal side of the face, (ii) a plurality of proximal strut portions extending distally from a proximal side of the face, and (iii) a plurality of sub-struts, wherein, from each proximal strut portion, two of the sub-struts each extend to a different one of the distal strut portions.

A braided vaso-occlusive member formed out of first plurality of filaments interwoven with a second plurality of filaments, wherein filaments of the first plurality are helically wound in a first rotational direction along an elongate axis of the braided member, and filaments of the second plurality are wound in a second rotational direction opposite the first rotational direction, such that filaments of the first plurality cross over and/or under filaments of the second plurality at each of a plurality cross-over locations axially spaced along the elongate axis of the braided member, wherein at each cross-over location, the filaments of the first plurality cross over at least two consecutive filaments of the second plurality, then cross under only a single filament of the second plurality, and then cross over at least two additional consecutive filaments of the second plurality.

Disclosed herein is a bowl-shaped neck bridge with a distal-facing concavity and a central lumen. The neck bridge is inserted and expanded within a cerebral aneurysm. The, embolic members (such as embolic coils, embolic ribbons, or string-of-pearls embolic strands) are inserted through the central lumen into the aneurysm sac.

Provided herein is an occlusion device for implantation into a body lumen or aneurysm comprising, a continuous compressible mesh structure comprising axial mesh carriages configured end to end, wherein each end of each carriage is a pinch point in the continuous mesh structure. Also provided herein is a kit comprising the occlusion device disclosed herein and a means for delivery thereof. Methods of manufacture and use of the occlusion device are also disclosed.

An aspiration system includes a pump and a control system in communication with the pump. The control system includes a microcontroller, an antenna configured to receive a signal, and a pump control board in communication with the microcontroller. The antenna is in communication with the microcontroller. Upon receiving the signal, the pump control board operates the pump to create negative pressure according to the signal.

Provided is a device for delivery into a body lumen having a longitudinally extending stem and a plurality of bristles extending generally radially outwardly from the stem. The device includes at least two different groups or types of bristles.

Devices and methods for treating vascular defects, such as, for example, balloon-type aneurysms, are described herein. In one embodiment, an apparatus includes an insertion portion and an expandable implant. The expandable implant is configured to be deployed in an aneurysm and is coupled to the insertion portion. The expandable implant has a first portion and a second portion coupled to the first portion. The expandable implant is movable between a first configuration in which the first portion and the second portion are substantially linearly aligned and a second configuration in which the second portion at least partially overlaps the first portion.

A flow restrictor (50) for an embolization device (10), the flow restrictor having an inner hole (52) for receiving a stem (20) of the embolization device to mount the flow restrictor on the embolization device, wherein the flow restrictor comprises: a membrane (56) for restricting flow in the bodily lumen, having a first elasticity; and a reinforcing section (54) having a second elasticity and at least partially surrounding the inner hole.
