Intravascular device for anchoring an implantable device to tissue

A method of deploying a tissue anchoring device at a target location within a patient, the method comprising:

• delivering a tissue anchoring device in a collapsed configuration, the tissue anchoring device comprising a radially expandable frame configured to transition between the collapsed configuration and an expanded configuration where a ring of expandable struts of a plurality of expandable struts of the radially expandable frame is angled radially outward relative to a remainder of the plurality of expandable struts;
• partially releasing the tissue anchoring device at the target location such that the ring of expandable struts contacts an inner wall at the target location thereby stabilizing the tissue anchoring device at the target location;
• and
• fully releasing the tissue anchoring device such that a proximal portion of the radially expandable frame transitions from the collapsed configuration to the expanded configuration at the target location.
