Abstract: An ingestible device includes a cylindrical capsule having a central axis defined therethrough, a proximal end portion, and an atraumatically shaped distal end portion. A propulsion unit is disposed at the proximal end portion of the capsule for effecting movement of the capsule within an in vivo environment.

Abstract: A wearable antenna assembly includes a posterior antenna assembly and an anterior antenna assembly. The posterior antenna assembly may include a posterior base that includes a lateral portion having a lateral line, and one or two protrusions that continue from the lateral portion and extend away from it, and one or more antenna elements that are formed in the respective protrusion. The protrusions may be configured such that each antenna element lies on the buttocks and is situated adjacent to, or in front of, a greater sciatic notch of the pelvis. The anterior antenna assembly may include an anterior lateral base having a lateral line, and n antenna elements that are formed in the anterior lateral base along the lateral line. The anterior lateral base may be configured such that, when the belt is worn, the n antenna elements are situated adjacent to, or in front of, the abdomen.

Abstract: A self-expansible structure for implantation in a body cavity is provided. The structure has a generally tubular outline, a nominal length, a nominal diameter, and a unique behavior under constraint. The unique behavior is expressed by a transition diameter, at which a constrained behavior of the structure changes so that, at a constraining diameter smaller than the transition diameter, the structure conforms to the constraint by decreasing the structure's diameter, to below the nominal diameter, and elongating beyond the nominal length, while at a constraining diameter larger than the transition diameter but smaller than the nominal diameter, the structure conforms to the constraint by decreasing the structure's diameter below the nominal diameter, while substantially maintaining the nominal length.

Abstract: A deployment device for deploying a self-expansible medical implant at a target location in a body cavity, is provided. While generally, the expansion of self-expansible structures tends to be abrupt, and the impact of expansion may cause injury, a two-stage expansion process of the present invention minimizes the impact of exapnsion. Additionally, an ability to manuever the medical imlant into position, after the first stage of expansion, provides for accurate positioning.
