Cooley Atraumatic Tissue Forceps — 24 cm, Pattern 343

Cooley Atraumatic Tissue Forceps — 24 cm, Pattern 343 (Ref DF 03-343-01) — Smooth atraumatic jaws minimize crush injury to delicate tissue, preserving vascular integrity and reducing post-operative inflammation.

Denton A. Cooley — DeBakey’s contemporary and rival in mid-twentieth-century Houston heart surgery — lent his name to a family of atraumatic vascular instruments used across cardiac and vascular operations. Cooley patterns include vascular forceps (similar to DeBakey but with subtly different jaw geometry), atrial retractors, and vascular clamps. The Cooley atraumatic forceps’ fine longitudinal serration grips vessel walls reliably without crushing. Lengths of 15 cm, 18 cm, and 24 cm are standard. The Cooley name remains prominent in cardiac surgery instrument sets despite the field’s evolution; many of his original patterns are still manufactured unchanged.

Manufacturing compliance is verified through ISO 13485:2016 certification (the international medical-device quality standard), CE marking under EU MDR 2017/745, and FDA establishment registration. Certificate copies and regulatory documentation are available on request for inclusion in hospital procurement files and EU technical documentation packages. Sterilization validation follows ISO 17665 for steam autoclave at 134 °C.
