Abstract: Endoscopic cannulas and methods of their use are disclosed. In some embodiments, an endoscopic cannula may include an elongated body having a proximal end and a distal end. A viewing channel and a working channel may extend through the elongated body. The viewing channel can be configured for passing therethrough an endoscope to the distal end of the elongated body for viewing outside the elongated body, while the working channel can be configured for passing therethrough an injection needle distally of the elongated body. The cannula may also include a suction pod disposed on a bottom surface of the elongated member, the suction pod being in communication with a suction channel extending through the elongated body to create suction between the suction pod and a tissue surface to temporary attach the elongated body to the tissue surface.

Abstract: Tissue restraining systems and devices as well as methods of using these devices are disclosed herein. According to aspects illustrated herein, there is provided a tissue restraining device that may include an annuloplasty member having one or more contact points along a portion of the annuloplasty member in a spaced relation to one another. The tissue restraining device may also include a second anchor for placement in a substantially opposing, spaced relation to the annuloplasty member. A restraining matrix may extend from the contact points of the annuloplasty member to the second anchor.
