A malleable cannula () for fluidically coupling with an anatomical structure includes a flexible cannula body wall () having a proximal end (), a distal end (), and a lumen () extending longitudinally between the proximal end () and the distal end (). The proximal end () defines a first opening () to the lumen () and the distal end () defining a second opening () to the lumen (). A channel is defined by a portion of the cannula body wall and extends longitudinally from the distal end () toward the proximal end (). The channel has a first end oriented toward the proximal end of the cannula body wall. A malleable member () is provided within the channel and is fixedly connected to the cannula body wall () at the first end of the channel. The malleable member () is configured to assume and maintain a formed shape of the cannula body wall ().

Malleable cannula

A surgical cannula system. The surgical cannula system includes a cannula having a proximal end, a distal end, and a lumen extending therebetween. A tissue attachment ring, being configured to be coupled to a biological tissue, includes a lumen extending therethrough. A locking mechanism has a first locking state, in which the cannula is configured to move with respect to the tissue attachment ring, and a second locking state, in which movement of the cannula with respect to the tissue attachment ring is resisted.
