EMBOLIC CAPTURING DEVICES AND METHODS

摘要

Disclosed is an emboli capturing device having a first support hoop (20, 420) at a distal portion of a first elongate member (10, 410), and a support member (30, 430) that is coupled to the first support hoop. The support member can comprise, a second elongate member. In some cases, the second elongate member can. be coupled to the first support hoop. In other cases, the support member can comprise a second elongate member and a support strut. The support strut can be coupled to both the first support hoop and the second elongate member. Movement of the support member relative to the first elongate member can translate the first support hoop between collapsed and expanded configurations. Once in a desired configuration, the support members can also provide support to maintain the first support hoop in the desired- configuration. Also disclosed is a combination emboli capturing and perfusion device (812). The combination device can have a perfusion member in combination with an emboli capturing device. The perfusion member can facilitate the introduction of fluids around a lesion in a vessel of a patient, for example if the lesion is creating a partial or total occlusion of the vessel.
