Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
