Abstract:
A surgical sealing sleeve for preventing undesirable leakage from the humoral fluid filled interior of a mammal organ to an access environment during its temporary seating in an access tissue to the mammal organ, the surgical sealing sleeve comprising:(a) an axially extending rigid tubular sleeve for attachment to the access tissue and having an axially extending passageway, said sleeve including an outer sleeve member and an inner sleeve member nested at least along a portion of its length within said outer sleeve member, each of said inner and outer sleeve members having a proximal end and a distal end, said inner sleeve member having at least one distally directed sheath support member terminating proximal to said distal end of said outer sleeve member; and(b) an elastomeric sheath sealingly interdisposed between said inner and outer sleeve members and distally extending so as to fit over said at least one sheath support member, said elastomeric sheath having an initially sealed end adapted to be cut in situ so as to provide an unidirectional slit valve normally closed under the pressure prevailing in the mammal organ's interior so as to prevent leakage of its contents therefrom via said passageway to the access environment.
