TROCAR-CANNULA COMPLEX, CANNULA AND METHOD FOR DELIVERING BIOLOGICALLY ACTIVE AGENTS DURING MINIMALLY INVASIVE SURGERY

摘要

A trocar-cannula complex 10 for use in minimally invasive surgical procedures performed through a port site of a patient and in the delivery of biologically active agents to the patient includes a trocar 12 and a cannula 16. The cannula 16 includes a tubular structure with a central lumen receiving the trocar 12 and an outer surface adapted to interface with tissue at the port site. A first delivery mechanism 18 is associated with the cannula 16 for delivering a first biologically active agent to a patient and a second delivery mechanism 18’ is associated with the cannula 16 for delivery of a second biologically active agent to the patient. Various other manners of delivering the agents are also disclosed.
