Abstract: A generally spherical vascular remodeling device is permanently positionable at a junction of afferent and efferent vessels of a bifurcation having an aneurysm. After positioning the device at the junction 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 mechanical or electrolytic release from a catheter. Embolic material may be inserted in the aneurysm before or after positioning the device. The device may have a first end, a second end substantially opposite to the first end, and a plurality of filaments extending between and coupled at the first end and the second end. Such devices may be football shaped, pumpkin shaped, or twisted. The device may include a plurality of loops forming a generally spherical shape.

Abstract: 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.
