An intubating LMA construction features a rigid airway tube wherein curvature in a single plane establishes essentially an arcuate path of angular extent in the preferred range of 130°, plus or minus 5°, which I have found to be in substantial anatomical conformance with the adult human's airway path, between a proximal end of the arc at substantial register with the longitudinal midpoint of the hard palate, and a distal end that faces and is at short offset from the glottic aperture, it being understood that my findings apply to suitably quantified allowance for variations in patient-head anatomy, as is for example customary for different sizes of LMA devices, each of which is adapted to serve one of five selected patient-size ranges. The proximal end of the rigid tube is suitably a short straight portion which is tangentially and integrally related to the proximal end of the arc. And the distal end of the arc is fitted with flexible mask structure of preferably elastomeric material such as silicone rubber, wherein an internal ramp formation within the mask structure assures a limited but important measure of further and stabilized guidance of an ET which has emerged from the distal end of the rigid tube, such that unguided displacement of the ET (i.e., beyond the ramp) is oriented to target safe entry of the ET into the glottic opening.

An isolated heart or heart-lung preparation in which essentially normal pumping activity of all four chambers of the heart is preserved, allowing for the use of the preparation in conjunction with investigations of electrode leads, catheters, ablation methods, cardiac implants and other medical devices intended to be used in or on a beating heart. The system can be designed to be used within a Magnetic Resonance Imaging (MRI) unit or a X-ray computed tomography (CT) scanner. The preparation may also be employed to investigate heart and lung functions, in the presence or absence of such medical devices. In order to allow comparative imaging visualizations of either or simultaneously the heart and/or lung structures and devices located within the chambers of the heart or vessels or bronchi within the lungs, a clear perfusate such as a modified Krebs buffer solution with oxygenation is circulated through all four chambers of the heart and thus the coronary and/or pulmonary vasculatures. A ventilator with intubation tube can be used to inflate/deflate the lungs and/or provide oxygen to the isolated organs. The preparation and recordings of the preparation may be used in conjunction with the design, development and evaluation of devices for use in or on the heart and/or lungs, as well as for use as an investigational and teaching aid to assist physicians and students in understanding the operation of the cardiopulmonary system.
