First Claim
1. A retraction guidewire formed as a single, continuous length of material in which the guidewire defines a first end, a second end, and a length between the first end and the second end and is configured to transition from an elongate configuration to a deployed configuration, the single, continuous length of material between the first and second ends being configured to elastically recover from the elongate configuration to the deployed configuration in which the single, continuous length of material defines:
- a stem portion; and
a dome portion having a distal end and a proximal end, the stem portion extending proximally within the dome portion from the distal end of the dome portion past the proximal end of the dome portion, the dome portion having a first side and a second side defined laterally opposite the first side, and the dome portion including,a first contact loop on the first side of the dome portion that extends from the distal end to the proximal end of the dome portion, anda second contact loop on the second side of the dome portion that extends from the distal end to the proximal end of the dome portion,the first contact loop including a first leg portion, a first foot portion, and a second leg portion, the first leg portion sweeping proximally from the stem through an arcuate path, the first foot portion extending arcuately from the first leg portion to define a bottom contact surface at a proximal end of the dome portion, and the second leg portion extending distally from the first foot portion.

Abstract
Retraction guidewires are disclosed, including retraction guidewires configured to transition from an elongate configuration for delivery to a treatment site through an organ wall to a deployed configuration for retraction of the organ wall, for example. The deployed configuration includes a stem portion and a dome portion having a distal end and a proximal end, the stem portion extending proximally from the distal end of the dome portion.
