Monofilament is thread drawn as a single strand, as against a multifilament (braided) thread of several strands.

In TissueDB monofilament reaches the trainee as a suture. It is a consumable used on the model, not a material that stands in for a tissue, so this page carries no tissues table. Construction (monofilament or braided), material and USP gauge are recorded thread by thread and build by build on Suture.

Monofilament thread is bought sterile and pre-packaged, usually mounted on a needle, and is single-use per pass — the same purchase and disposal pattern as the rest of the Suture class. TissueDB records one build that calls for monofilament by that name: the Hanssen hernia model, in the table below.

Consumables

Consumable	Quantity	Approximate Cost	Simulator	Notes
Monofilament suture			Laparoscopic Inguinal Hernia Repair Simulator (Hanssen)	Closes the peritoneal flap, with intra-corporeal knotting, as the fifth and last step of the simulated repair. The source names the thread only as "a monofilament suture" — it states no gauge and no polymer.

Troubleshooting

• It is not a tissue simulant. Monofilament stands in for no tissue. A build that needs a thread-like tissue surrogate — a vessel, a nerve, a tendon — takes it from the material recorded for that tissue, not from here.
