  • Patent number: 6471695
    Abstract: The present invention provides improved methods, systems, and kits for protecting body tissues which are adjacent to tissues undergoing thermal treatment. Thermal treatment is often prescribed for tumors and other disease conditions within body organs and other tissue masses. The methods, systems, and kits are particularly useful for treating tumors which lie at or near the surface of an organ, such as the kidney, pancreas, stomach, spleen, and particularly the liver. One risk of treating such tumors is the possibility of mistargeting the tumor and penetrating a delivery cannula or portions of a treatment device beyond the surface into the adjacent tissues or organs. In the case of radiofrequency or electrosurgical treatment, healthy surrounding tissue may be directly ablated. An additional risk, present even when the tumor is correctly targeted, is the possibility of thermal damage to the surrounding, non-targeted tissue.

  • Patent number: 4964417
    Abstract: A device for assisting wound closure in a surgical procedure in the form of a silicon rubber suture mat (1,3) and having a front region (2) of generally lenticular shape and an integral narrower tail region (3), the sides (3') of which are mutually biconcave with respect to the biconvex sides (2') of the front region (2) and are continuously curved therewith. When closing a wound, the front region (2) is used to cover, protect and retain the internal organs by being tucked under adjacent tissue, with the tail region (3) protruding from the wound. After the wound has been almost completely closed, the mat, due to its shape and inherent flexibility may be smoothly removed through a small remaining wound aperture (11) prior to final closure.

  • Patent number: 4926882
    Abstract: The invention discloses a protective device for use during autopsy by a prosector operating with handheld instruments. The autopsy subject is covered by a transparent dissection chamber-forming device which is attached to the draped about the body of the subject. By attaching the device to the body of the subject the dissection site is isolated from the prosector and his support staff. The device provides an instrument port through which the handheld instrument can be partially inserted and further the device provides for sealing against the instrument. In addition to the device, a method of protecting autopsy room staff is also disclosed. Through the device and the associated method, the prosector is enabled to use, with an unobstructed view of the autopsy subject, handheld instruments while the effluent from the dissection of the autopsy subject is restricted within the sealed dissection chamber. The autopsy room staff is thus protected from infection.
