Abstract: A steerable guidewire apparatus for use during percutaneous catheter interventions such as angioplasty or stent deployment. A protection element comprising a filter or an occluder is mounted near the distal end of the steerable guidewire, which guides a therapeutic catheter. The guidewire comprises a hollow shaft movably disposed about a core wire. The shaft and core wire control separation of the ends of the protection element, causing transformation of the protection element from a deployed configuration to a collapsed configuration. Farther separation of the ends of the protection element, after it has been collapsed, causes deflection in a distal region of the apparatus.

Abstract: A control handle for an intraluminal device includes a handle housing having a first end and a second end, the handle housing having a lumen. A roller assembly is disposed at a first end of the lumen. The roller assembly comprises a first roller and a base. The lumen is interposed between the first roller and the base. A clamp assembly is disposed at the second end of the lumen. The clamp assembly comprises a first clamp element and a second clamp element. The lumen is interposed between the first clamp element and the second clamp element. A closure mechanism is configured to effect movement between the first clamp element and the second clamp element and between the first roller and the base. The control handle further includes a turn device operably connected to the roller assembly.
