intracorporeal

Intracorporeal describes something that occurs, is performed, or exists within the body. In medical terminology it is used to distinguish actions or components that take place inside the patient from those conducted outside the body (extracorporeal). The term is applicable across a range of procedures, devices, and techniques, particularly in surgery and interventional medicine.

Derived from the Latin intra- for within, corpus meaning body, and the adjectival suffix -al, intracorporeal literally means “within the body.”

In surgical practice, intracorporeal techniques are those carried out entirely inside the body's cavities using instruments introduced through small incisions or natural orifices. This contrasts with extracorporeal methods where steps are performed outside the body and then transferred inside. Examples include intracorporeal suturing and intracorporeal knot-tying in laparoscopic surgery, intracorporeal anastomosis, and intracorporeal lithotripsy to fragment stones within the urinary tract.

The term is also used to describe devices or actions that operate within the body's interior, such as intracorporeal endoscopy, intracorporeal lithotripsy, or other minimally invasive interventions. In context, intracorporeal denotes localization or execution inside the body, as opposed to extracorporeal approaches that occur outside the body before introduction or deployment. The concept underscores procedural steps, equipment, or techniques designed to function within the anatomical confines of the patient.
