2. Fig 1
Three types of Octopus Tissue Stabilizer paddles are demonstrated. The straight version is shown attached to the heart model, with both left and right modifications demonstrated. In the center a single version of the offset paddle is demonstrated. To the right, the so-called preformed version is shown. The metal just beyond the plastic handle is malleable.

3. Fig 2
Application of the Octopus through limited surgical access; (a) via a small anterior thoracotomy on the anterior cardiac wall on either side of the left anterior descending artery, diagonal branch, or both, with one paddle installed via the surgical wound and one via a stab wound that is used for the chest drain afterwards; (b) via a subxiphoid incision to expose the distal right coronary artery and proximal posterior descending artery.

4. Fig 3
Application of the Octopus through full surgical access: via sternotomy, exposing the left anterior descending artery, diagonal branch, or both (a), distal right coronary or posterior descending artery (b), and obtuse marginal branch (c); via posterior thoracotomy to expose the circumflex artery or its branches and the left anterior descending artery (d).
