Abstract: A flexible thermal jacket of a generally thin flat arcuate configuration having a thermal transfer face and a thermal insulating face comprises, a first thin flat sheet of impervious material having an arcuate inner and outer edge, a second sheet substantially identical to said first sheet bonded to the first sheet along the arcuate edges and along lines defining an elongated serpertine passages throughout the jacket, and a generally circular insulating tab formed of inner and outer impervious sheets and an inner thermal sheet secured to the inner edge and operative to close and or cover an opening formed by forming the jacket into a frusto-conical configuration.

Abstract: A suction dissector for performing coronary, systemic or pulmonary thromboendarterectomy includes a unitary elongated instrument having an elongated tubular handle section and an elongated tubular probe section having a bore. The handle section has a connector at an outer end thereof for attachment to a source of vacuum. The probe section has a rounded tip and a plurality of ports in the tip for communicating with the bore. The probe section may angled relative to the handle.

Abstract: A temperature probe for insertion into the tissue of an organ, such as a heart, during surgery comprises an elongated needle made of plastic with a large button type head, and having one or more sensing elements disposed at selected positions along the length thereof for sensing the temperatures at various depths, with a surface temperature sensor positioned just beneath the head in the needle.

Abstract: A pad for cooling the heart or other similar organs during surgery comprises a pad of a generally flat configuration constructed of a pliable material having heat transfer means in the form of a conduit for conducting a coolant through the pad adjacent one surface and an insulating device in the form of an air chamber insulating the cooling apparatus from the opposite face of the pad and including a malleable frame within the pad for maintaining the pad in selected configurations for folding around an organ, and retaining the pad in position.
