Some companies do offer silicone-drains with a stab (trocar) inside. These trocars are designed for optimal guidance and positioning of the chest tube. The trocars can end bluntly in the tube with an integrated plastic cap to prevent organ injuries shields the tip. Other suppliers offer drains with trocars having round or even sharpened tips to facilitate the penetration of the tissue. The hazards of these drains are discussed in detail in Chap. 7 (Figs. 4.3, 4.4, 4.5, and 4.6).

Rinse-Suction Drains have a large bore channel for suction and evacuation of air/fluid and a small bore channel normally used for installation of rinsing fluid (Fig. 4.7).

Capillary drains or Jackson-Pratt drains have multiple small channels or holes that lead to an increase surface area resulting in an increased diameter. At the same time the principle of capillary perforation is supposed to avoid clogging of the drain (Fig. 4.8).

Aspiration drains are designed to evacuate air and fluid from the pleural space in an acute situation. Therefore the drains may be thin walled and are removed immediately after use. A Luer-Lock-connector is typically added to connect syringes or a evacuation bag. These catheters are made of silicone-polyethylene mixtures and should be removed at least three days after initial use. Commercial available drains normally contain an application set (Redax SpA, Sede legale, Poggio Rusco, Italy) (Figs. 4.9 and 4.10).

Pigtail-catheters are mainly used during CT or ultrasound guided interventions: The guide-wire or a trocar is placed in the target area followed by the definitive catheter which is guided by the wire or the cannula. The ability of the end of the catheter to corkscrew is created during the manufacturing process and gave the product its name (“pig tail”). This configuration minimizes the risk of dislocation in situ (B. PraxiMed Vertriebs GmbH, Zwönitz, Germany) (Fig. 4.11).
