PROTEUS Solution

Providing a Smart Device for Embolic Capture Angioplasty (ECA)

The Angioslide PROTEUS™ device is the first stand-alone device to combine balloon angioplasty with embolic (debris, thrombus) capture and removal capabilities during lower limb procedures.  The PROTEUS embolic capture feature is uniquely integrated into an angioplasty balloon, providing onsite embolic removal at the point of disruption through the device suction mechanism.

Emboli, a Complication of At-risk Peripheral Interventions

Large embolic loads can occlude key downstream vessels, consequentially resulting in re-interventions such as a thrombectomy, overnight thrombolysis, surgical revisions or limb loss.1 PROTEUS offers an effective and easy to use technology that enables you to capture embolic particles dislodged, at the lesion site, during balloon angioplasty of the Infrainguinal arteries.

How does it Work?

PROTEUS works just like an angioplasty balloon with the same physical and behavioral characteristics, such as inflation time, deflation time, pushability, and crossing profile. In addition, PROTEUS embolic capture feature involves a single-use suction mechanism that works through inward folding of the balloon, which creates negative pressure within the capture cavity for debris capture and removal. The reduced pressure in the capture cavity causes embolic (debris, thrombus) particles that are released during the procedure to flow into the cavity for containment
and removal



PROTEUS integrates in every step of the procedure:

PROTEUS is an ideal solution for lower limbs angioplasty interventions, from vessel preparation (first in the lesion) to PTA rescues procedures following primary intervention. PROTEUS is a useful tool in many clinical settings in the infrainguinal (SFA and infrapopletial) arteries:


  • Occlusive and sub-occlusive lesions
  • Flow limiting & thrombus containing lesions
  • In stent occlusions
  • Post atherectomy and post thrombectomy dilatation

PROTEUS is designed to effectively treat lower limb plaque by combining dilatation of stenotic lesions and embolic capture through suction mechanism for debris capture and removal.
