An intravascular device for treating a cerebral aneurysm which has an externally controllable expandable member, the expandable member has a plurality of wires that define walls of the expandable member; where in a relaxed state of the expandable member the walls have at least a first wall portion in which openings defined between the wires are small enough to prevent coils positioned within the aneurysm from exiting the aneurysm, the first wall portion has an axial length at least as long as a neck of the aneurysm; and at least a second wall portion in which openings defined between the wires are large enough to allow blood flow through; the second wall portion axially aligned relative to the first wall portion.

Aneurysm treatment device and method

A system for removing a thrombus. The system includes an expandable device that maintains axially fixed engagement with the thrombus. The expandable device applies a first force to the thrombus according to surrounding vessel size. The expandable device applies a second force to the thrombus according to an increased vessel size to maintain axially fixed engagement.

Method and apparatus for occlusion removal

A device arranged to sustain and/or provide at least partial patency of a small blood vessel exhibiting an occlusion, the device constituted of a tubular body expandable from a first small diameter state for manipulation to, and through, the occlusion of the small blood vessel and a second large diameter state, the inner dimensions of the second large diameter state being no more than 50% of the diameter of the small blood vessel at the occlusion location, the device presenting a conduit for blood flow through the occlusion when in the large diameter state. In one embodiment the small blood vessel is an intracranial blood vessel.

Method and apparatus for allowing blood flow through an occluded vessel

According to an aspect of some embodiments of the present invention there is provided a device for removal of obstructive material from a vessel comprising:

Apparatus and method for vessel occlusion removal

An intravascular device for treating a cerebral aneurysm which has an externally controllable expandable member, the expandable member has a plurality of wires that define walls of the expandable member; where in a relaxed state of the expandable member the walls have at least a first wall portion in which openings defined between the wires are small enough to prevent coils positioned within the aneurysm from exiting the aneurysm, the first wall portion comprising an axial length at least as long as a neck of the aneurysm; and at least a second wall portion in which openings defined between the wires are large enough to allow blood flow through; the second wall portion axially aligned relative to the first wall portion.

Implant for supporting bodily conduits, such as blood vessels or/and grafted vessels, inside a subject. In exemplary embodiments, the implant includes a support fixedly displaceable and plastically stretchable to points along longitudinal axis of the support, when subjected to a stretching force, thereby forming a new shape, the support substantially maintains the new shape upon removal of the stretching force. The support, when forming the new shape, is plastically reversely compressible in a direction along the support longitudinal axis, when subjected to axially compressive force. Support may include a radially elastic portion configured to regain fixedly deformed diameter upon removal of radially compressive force applied thereto. Support is configurable as an intraluminal support for intraluminal deployment and setting in a conduit segment, or, as an external support for enveloping a conduit segment, so as to change route or/and shape of the conduit segment.

Implant for supporting bodily conduits such as blood vessels or/and grafted vessels

Methods of supporting a vein, featuring deforming a vein support while being mounted on the vein. Such deformation may be sufficient to impose thereupon a plastic deformation that alters a length of the vein support, from a pre-deformation relaxed length to a post-deformation relaxed length different than the pre-deformation relaxed length. Following the plastic deformation, the vein support may maintain a new shape relative to a longitudinal axis thereof.

Methods of supporting a vein

An external vein support comprising an elongate axial body including an axis, said body is plastically deformable by at least one of stretching, bending, twisting, and any combination thereof, relative to said axis.

External stent

A braided device comprising: filaments of a first type and of a second type, the second type differing from the first type in at least one characteristic; the first type of filaments defining an integral symmetrical 1&#xd7;1 sub-pattern; and the combination of the first type of filaments and the second type of filaments being braided together into a braided device exhibiting a uniform braid pattern.

Mixed wire braided device with structural integrity

A method of and an apparatus for making a braided intraluminal implant, by providing a mandrel having at least one small-diameter section joined at least at one end to a large-diameter section; interweaving a plurality of filaments to form a tubular braid enclosing at least a part of the small-diameter section and at least a part of the large-diameter section; and cutting the tubular braid to produce a tubular braid segment having outwardly flared ends at its opposite ends. One flared end is produced by the large-diameter section of the mandrel, and the opposite outwardly flared end may be produced either by another large-diameter section of the mandrel, or by cutting the tubular braid at a portion formed by the small-diameter section of the mandrel but at a location wherein the release of stresses in the filaments inherently produces an outward flaring of the braid at that end.

Method and apparatus for making intraluminal implants and construction particularly useful in such method and apparatus

A striped braided element comprising: a first set of members having a common direction of winding, the center axis of said first set of members being axially displaced relative to each other in relation to a common braiding axis; and a second set of members having an opposite direction of winding, the center axis of the second set of members being axially displaced relative to each other in relation to the common braiding axis, the braided element exhibiting a uniform uninterrupted braid pattern and an average uniform distance between the center axis of members having a common direction of winding at a particular circumferential section along the common braiding axis; characterized by having at least one stripe comprising two adjacent members of the same set exhibiting a significantly reduced distance between the center axis of the adjacent members in the particular circumferential section.
