  • Patent number: 10076239
    Abstract: A medical system generally comprises a camera head, a beam, and a guide sheath. The camera head is connected to the beam which is bendable in a first direction and resists bending in a second direction opposite the first direction. The guide sheath slidably receives the beam, the beam extending through a distal end of the guide sheath such that the camera head projects from the distal end of the guide sheath. The guide sheath includes first and second sheath portions, and in an operative configuration the first sheath portion is angled relative to the second sheath portion to define a first bend. The beam is oriented relative to the guide sheath such that, as the beam is slid relative to guide sheath, the beam bends in the first direction through the first bend, and a projecting portion of the beam resists bending in the second direction.

  • Patent number: 9523522
    Abstract: In some embodiments, a refrigeration device includes: walls substantially forming a liquid-impermeable container configured to hold phase change material internal to a refrigeration device; at least one active refrigeration unit including a set of evaporator coils positioned within an interior of the liquid-impermeable container; walls substantially forming a storage region; and a heat transfer system including a first group of vapor-impermeable structures with a hollow interior connected to form a condenser in thermal contact with the walls substantially forming a liquid-impermeable container, a second group of vapor-impermeable structures with a hollow interior connected to form an evaporator in thermal contact with the walls substantially forming a storage region, and a connector with a hollow interior affixed to both the condenser and the evaporator, the connector forming a liquid and vapor flow path between the hollow interior of the condenser and the hollow interior of the evaporator.

  • Patent number: 9447995
    Abstract: In some embodiments, a regulated thermal transfer device for a storage container includes: a phase change material unit, the phase change material unit including one or more walls surrounding a phase-change material region, and an aperture in the one or more walls; a heat pipe with a first end positioned within the phase change material unit, and a second end; a thermoelectric unit thermally connected to the second end of the heat pipe; a heat sink connected to the thermoelectric unit, and positioned to radiate heat away from the thermoelectric unit; and an electronic controller operably connected to the thermoelectric unit; wherein the regulated thermal transfer device is of a size and shape to be positioned so that the phase change material unit is within a storage region of a temperature-stabilized storage container, and the thermoelectric unit is positioned adjacent to an external surface of the temperature-stabilized storage container.

The guide sheath slidably receives the beam, the beam extending through a distal end of the guide sheath such that the camera head projects from the distal end of the guide sheath.
