Methods for restoring blood flow in occluded blood vessels using an apparatus having a self-expandable distal segment that is pre-formed to assume a superimposed structure in an unconstrained condition but can be made to take on a volume-reduced form making it possible to introduce it with a microcatheter and a push wire arranged at the proximal end, with the distal segment in its superimposed structure assuming the form of a longitudinally open tube and having a mesh structure of interconnected strings or filaments or struts. In a preferred embodiment, the distal segment has a tapering structure at its proximal end where the strings or filaments or struts converge at a connection point.

Methods and apparatus for flow restoration

A clot retrieval device is provided. The clot retrieval device includes a capturing basket having an opening at a proximal end where the capturing basket is deployable downstream from a clot in a blood vessel. The capturing basket is configured to surround a portion of the clot and the opening in the proximal end of the capturing basket is configured to reduce in size such that the capturing basket conforms around the portion of the clot and be retrieved after the capturing basket conforms around the portion of the clot.

Device for removing an embolus

A clot retrieval device is described herein. The clot retrieval device includes a capturing basket that is deployable to the side of a clot in a blood vessel. The capturing basket is configured to allow for the clot to ingress into the capturing basket and surround at least a portion of the clot.

Devices and methods for removing an embolus

Vascular remodeling devices can include a proximal section, an intermediate section, and a distal section. During deployment, the proximal section can expand from a compressed delivery state to an expanded state and anchor the device in an afferent vessel of a bifurcation. The distal section expands from the compressed delivery state to an expanded state that may be substantially planar, approximately semi-spherical, umbrella shaped, or reverse umbrella shaped. The distal section is positioned in a bifurcation junction across the neck of an aneurysm or within an aneurysm. The intermediate section allows perfusion to efferent vessels. Before or after the device is in position, embolic material may be used to treat the aneurysm. The distal section can act as a scaffolding to prevent herniation of the embolic material. The device can be used for clot retrieval with integral distal embolic protection.

Vascular remodeling device

A medical device for blood flow restoration and/or for use as an implantable member in a human vessel includes a self-expanding member, a guidewire, and a connection mechanism. The self-expanding member includes a plurality of cells and filaments having specific ranges of thicknesses, widths, and heights. The self-expanding member can take on a volume-reduced coiled form with overlapped edges, and can generate optimal radial forces against a vessel wall and/or thrombus when deployed and expanded.

Methods and apparatuses for flow restoration and implanting members in the human body

Catheters of the present disclosure include a catheter shaft and an expandable tip, which can retrieve materials slightly larger than an inner diameter of the catheter shaft. The tip may be expandable such that it can easily transform from a first size and shape to a second size and shape to aid in the retrieval of the materials (i.e., the thrombus, embolus, or foreign body). Catheter tips may be expanded by inflation, removal of a constraining member, or an input such as heat, light, or electrical energy.

Retrieval catheter with expandable tip

An implantable lumen filter () is described. The implantable lumen filter includes a body () having a proximal end (), a distal end (), and a generally tapered outer surface (). The outer surface is formed by a plurality of struts (). The plurality of struts forms a plurality of apertures (). The apertures are dimensioned to inhibit and/or to lyse particulates of a selected size from passing through the apertures. The body () is transitionable from a collapsed state toward a deployed state. The implantable lumen filter includes an engaging portion () having a proximal end () and a distal end (). The proximal end of the engaging portion is connected to a distal end of the body. The engaging portion has a generally annular shape and is configured to engage an inner surface of a body lumen.

Apparatus for filtering a body lumen

An intraluminal apparatus including a catheter and device is positionable at a junction of afferent and efferent vessels of a bifurcation having an aneurysm. After positioning the device to substantially conform the device to the shape of the junction, the device acts as a scaffolding to inhibit herniation of objects out of the aneurysm and the device permits perfusion to the efferent vessels. Positioning the device may include deployment and optional release from a catheter. Embolic material may be inserted in the aneurysm before or after positioning the device. The device may have a proximal end, a distal end, and a plurality of filaments extending between and coupled at the proximal end and the distal end. The device may include a central filament configured to reshape the device. The distal end of the device may include a covering. The device may be football shaped, pumpkin shaped, or acorn shaped.

An implantable lumen filter is described. The filter may include a body formed from an elongate member. The body may include loops encircling an axis extending along the length of the body. The body may be sized to be implanted into a body lumen. The body may be capable of transitioning from a collapsed state to a deployed state. The filter may include a first group of a plurality of members positioned around at least one loop of said body. At least a portion of the plurality of members may be oriented towards the axis. The plurality of members may be arranged to capture and/or lyse particulates of a selected size and/or to inhibit the particulates from passing through the body. Methods to of making, deploying, and retrieving the same are described.
