  • Patent number: 4624252
    Abstract: An improved surgical device for performing thoracostomies and laparoscopies wherein the escape of air from the chest cavities or gas from the abdomen during such operations is prevented. The device includes a stylet holder wherein the holder includes needle halves having cooperating portions thereon for sealing off fluid flow when the portions are brought into contact. The stylet includes a needle having a bulged sharpened end adapted to seal off fluid flow so that fluid flows only through the needle. When the needle is withdrawn from between the needle halves, the needle halves are forced apart then mate so that the cooperating portions engage and seal off fluid flow.

  • Patent number: 4520810
    Abstract: An improved apparatus and method for performing an emergency cricothyrotomy comprising a tracheostomy device which can be inserted into a patient's neck without danger of puncture of the posterior wall and which permits insertion of an airway tube without popping out of the device from the incision in the patient's neck or penetrating the posterior wall. An airway tube can be quickly and easily substituted for another airway tube of differing internal diameter without the need for redefining the puncture area or utilization of additional instrumentation. If desired, a closed system can be quickly and easily coupled to the device without the need for making a bigger opening in the patient's neck.
