1. A heart tissue gripping device comprising:
- a body portion that is grippable by a user to allow the user to control the device such that one or more components of the device are insertable through an incision in a body to position the one or more components adjacent a surface of the heart;
an elongate shaft having a proximal end coupled with the body portion and a distal end;
a tissue gripping member that is fixedly coupled to the distal end of the elongate shaft so that the tissue gripping member is fixed in position relative to the distal end of the elongate shaft, the tissue gripping member having a main body and a lumen extending coaxially through the main body from a proximal most end of the main body to a distal most end of the main body, the tissue gripping member being insertable through the incision in the body so that the entire tissue gripping member is positionable within the body and against the heart surface when the tissue gripping member is inserted through the incision, the tissue gripping member being configured to releasably attach to tissue of the heart surface, wherein the distal end of the elongate shaft is attached to and extends laterally from a sidewall of the main body between the distal most end and the proximal most end of the main body such that the elongate shaft extends off-axis from the lumen of the tissue gripping member and such that when the tissue gripping member is inserted within the incision, the proximal most end of the main body is disposed within the body so as to be exposed to the surrounding environment within the body while the distal most end of the main body is positioned against the heart surface; and
a coupling feature for releasably attaching a catheter device and/or tissue penetrating device to the tissue gripping member to allow said device to access the tissue of the heart surface;
wherein the proximal end of the elongate shaft is directly coupled to the body portion such that when the entire tissue gripping member is positioned within the body and against the heart surface, at least a portion of the elongate shaft is configured to remain outside the incision in the body.

Abstract
A heart tissue gripping device may include a body portion, an elongate shaft, and a tissue gripping member that is attached to the distal end of the elongate shaft. The tissue gripping member being may be positioned adjacent a heart surface by insertion through an incision in the body. The tissue gripping member may releasably attach to tissue of the heart surface to facilitate a surgical instrument in performing one or more procedures. A coupling of the tissue gripping member may releasably attach the surgical device to the tissue gripping member to allow the device to access the tissue of the heart surface.
