Problems solved by technology

The tortuousness or narrowness of the vessel may, in certain circumstances, lead to the formation of atherosclerotic plaque, which can cause further complications in the body.
In certain applications, the removal of the foreign object within the vessel may cause emboli to migrate upstream and enter other branching passageways within the body.

Abstract

Devices, systems and methods for removing foreign bodies within a body lumen are disclosed. An unfolding balloon catheter may include an elongated shaft having an intussuscepting balloon that can be actuated within a body lumen to capture and retrieve an intravascular device. The balloon may be configured to radially and/or axially expand when inflated, enveloping the intravascular device. In certain embodiments, the balloon may be formed by folding the ends of a distensible member inwardly, and then bonding the ends of the distensible member to the elongated shaft to form an expandable sleeve. An adhesive layer located along a portion of the elongated shaft may be used to temporarily secure the balloon to the elongated shaft.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to the field of intravascular devices. More specifically, the present invention pertains to catheter devices for proximal embolus protection within a body lumen. BACKGROUND OF THE INVENTION [0002] Embolectomy devices such as inflatable catheters and clot pullers are used in a variety of applications to remove blood clots or other foreign bodies from a blood vessel such as an artery or vein. The formation of thrombus within the vessel may partially block or totally occlude the flow of blood through the vessel, preventing the flow of blood downstream to vital locations within the body. Such thrombolytic events may also be exacerbated by atherosclerosis, a vascular disease that causes the vessels to become tortuous and narrowed. The tortuousness or narrowness of the vessel may, in certain circumstances, lead to the formation of atherosclerotic plaque, which can cause further complications in the body. [0003] In embol...
