4A Abscess Drainage Sets - Malecot Type

SKU: 4A-RA-0011

The Abscess Drainage Set (Malecot Type) is a specialized percutaneous drainage system utilizing a collapsible four-wing Malecot mechanism for maximum retention in large, superficial, or deep fluid cavities. Ideal for draining thick exudates, loculated abscesses, and necrotic debris, the Malecot wings expand upon deployment within the cavity to provide secure, non-slip anchorage without requiring a locking string. The set comes complete with a rigid inner stiffening cannula, puncture needle, guide wire, and dilators for rapid insertion.

Key Benefits

  • High-Flow Four-Wing Retention: Expandable Malecot wings maximize fluid contact area and hold the catheter securely in place.
  • Superior Viscous Debris Clearance: Open-wing geometry resists occlusion from thick pus, blood clots, and necrotic tissue.
  • No-String Mechanical Anchorage: Eliminates the need for external locking strings while maintaining firm internal position.
  • Removable Inner Stiffener: Rigid inner cannula straightens the wings for smooth percutaneous entry, releasing them upon removal.
  • Soft Biocompatible Material: Thermoplastic construction adapts to cavity contours, minimizing internal focal pressure.
