The present invention provides a device for inserting a catheter within the intercostal space to withdraw a fluid from that space. A hollow needle of a syringe is first inserted into the intercostal space to determine the presence or absence of the fluid and, if present, a guide wire is inserted through the needle, into the space and then the needle is withdrawn. A tubular catheter is then positioned over an elongated trocar so that the trocar carries the catheter. In addition, the trocar includes an axial throughbore designed to receive the guide wire. Consequently, with the guide wire positioned through the trocar throughbore, one end of the trocar as well as the catheter are forced into the intercostal space after which the trocar is withdrawn from the catheter. The catheter is then connected to suction equipment or the like to drain the intercostal space in the desired fashion.
