1. A device for implantation of a replacement heart valve, the device comprising:
- a carrier element having a tubular configuration, a first end, and a second end, the carrier element being deployable from a stowed position to a deployed position; and
a plurality of feeler elements being deployable from a stowed position to a deployed position, at least a portion of each feeler element being disposed laterally about the carrier element between the first end and the second end of the carrier element,wherein the feeler elements are deployable independently of the carrier element so as to protrude radially outwardly relative to the carrier element.

Abstract
The implant implantation unit, at a determined position in the tubular element with a wall comprising a cavity, is pushed there by a catheter and the unit comprises deformable feelers to, under the control of remote activation elements, change from a stowed form to a deployed functional form, to detect the cavity and position itself there with reference to the position of the cavity.
