1. A method for positioning an electrical sensing or stimulation device within a bodily cavity, the method comprising:
advancing an elongate lead body of the electrical sensing or stimulation device to position the elongate lead body at a target site in the bodily cavity; and
extending a plurality of tissue attachment members from the elongate lead body from a common port and diverge from each other and into or against the target tissue to affix a distal portion of the lead body to target tissue at the target site and contact at least one electrode of the electrical sensing or stimulation device to the target tissue,
wherein extending the plurality of tissue attachment members comprises translating a single wire coupled to the plurality of tissue attachment members within a lumen of the elongate lead body.
