0786234-A1 cites 9 patents.

A port (100) includes a body having a hollow portion (101) defining an axial bore, a flange (102) circumferentially disposed around a proximal end of the hollow portion and two spaced apart legs extending distally from the hollow portion, each leg having a distal end with a wing portion (105, 106) extending laterally therefrom. The thoracic port is inserted into the intercostal space between two ribs and turned to a locking position wherein the legs may advantageously bias the ribs to a more spaced apart configuration and the wings abut the distal surface of the ribs to prevent inadvertent withdrawal of the port.
