Keeper Endovascular Snare

Keeper Endovascular Snare

A multi-loop snare retrieval device for foreign body 或 embolus capture, ensuring secure engagement and withdrawal from vascular lumens.

Information

Keeper Endovascular Snare by INVAMED is a single-use, sterile device engineered to capture and retrieve intravascular foreign objects, from dislodged stents or guidewire fragments to thrombosis and other undesirable materials in the vascular system. With an innovative loop design and low-profile catheter introduction, the Keeper Snare provides precise control, maximum radial force, and minimized trauma—streamlining procedures in both arterial and venous settings.

Flexible Snare Loop Geometry
  • Constructed from high-tensile nitinol or stainless-steel wires in various loop diameters for optimal capture potential.
  • Retains shape memory and radial strength even after multiple manipulation cycles, supporting consistent retrieval.
  • Low-profile catheter sheath simplifies femoral, radial, or brachial access.
  • Catheter tip and snare loop are radiopaque, facilitating fluoroscopic or angiographic visualization and precise target approach.
  • The snare loop compresses or expands under operator control, securely gripping foreign bodies or occlusive elements without risk of fragmenting them further.
  • A dedicated handle or torque device (depending on model) provides precision in loop rotation and retraction.
  • Reduces or eliminates the need for open surgical extraction, shortening patient recovery times and lowering complication risks.
  • Effective for broken guidewires, catheter fragments, or other intraluminal materials that must be removed promptly to avoid embolization or vascular injury.
  • Suitable for arterial or venous retrieval in peripheral vessels, central vasculature, or even select cardiac chambers if indicated.
  • Helpful in addressing intravascular coil misplacements, filter retrievals, or spontaneous foreign body presence.
