Abstract: A downhole system may include a housing securable to a conveyance, a first linkage base disposed proximate a first shoulder of the housing in a collapsed position, and a second linkage base disposed proximate a second shoulder of the housing in the collapsed position. Further, the downhole system may include a shifting key configured to move between the collapsed position and an expanded position in response to movement of the first linkage base and/or the second linkage base. The shifting key is secured to the first linkage base via a first linkage arm and to the second linkage base via a second linkage arm. The first linkage base is configured to contact the first shoulder of the housing, with the shifting key in the expanded position, to transfer a load on the shifting key to the housing through the first linkage arm and the first linkage base.

Abstract: There is provided an apparatus for extraction of at least one object from a cavity. The apparatus includes a sleeve including an inflatable section configured to surround the at least one object during inflation; a handle configured to enable a user to hold the sleeve, the handle defining a holding edge of an opening at a first portion of the sleeve; and a handle-mount mounted to a peripheral area around the opening, the handle-mount being for attachment of a pump used for inflating the inflatable section. There is also provided a pressure limitation apparatus configured to operate with a birth assistance device when attached via a conduit.
