Abstract: Mechanisms are disclosed for securing a catheter in place to facilitate puncturing a hole through a vessel wall. The securing mechanisms include mechanically releasing arms that press against the wall of the vessel. The mechanically releasing arms are advanced out of the catheter. Outside of the catheter, the securing mechanisms angle or curve toward the vessel wall to contact the wall. The more the mechanically releasing arms are advanced, the closer the approach to the wall and the more force placed against the wall to anchor the catheter in place. The mechanically releasing arms include a plurality of wires that angle or curve toward the vessel wall when deployed, one or more wires that coil away from the catheter to contact the vessel wall when deployed, or a stopper arm with a curved endcap that contacts the vessel wall when deployed.

Abstract: Mechanisms are disclosed for securing a catheter in place to facilitate puncturing a hole through a vessel wall. The securing mechanisms include bubbles, meshes, flaps, or similar features that expand when activated to press against the wall of the vessel (e.g., coronary sinus). Activation of the securing mechanisms occurs through removal of a restraint (e.g., a cover) or by pushing or pulling a wire. The securing mechanisms activated by removal of a restraint may self-expand or may expand due to a spring within a mesh structure. The securing mechanisms activated by pushing or pulling a wire expand due to movement of the wire itself or due to movement of a component attached to the wire and to the anchor member.
