  • Patent number: 9077132
    Abstract: The present invention relates to an elongated male connector (1), for a medical device, and a method of producing the male connector (1). The male connector (1) has a longitudinal axis (2) and comprises a plurality of conductive members (3), each having an outer contact surface (4) and being separated from each other by insulating members (5). The conductive and insulating members (3, 5) are disposed along the male connector (1), such that the outer contact surfaces (4) are arranged essentially at the same surface level, and that each of the conductive members (3) has an elongated extension along the longitudinal axis (2) of the male connector (1). Each conductive member (3) is provided with an insulated microrod (6) extending at least partially along the length of the male connector (1), and the conductive members (3) are hollow and have an essentially cylindrical cross-section and form, together with the insulating members (5), a self-supporting male connector (1) having no core wire.

  • Patent number: 8858591
    Abstract: A method for sealing a hole in a bodily organ includes introducing a first member and a second member into the bodily organ, the first and second members being connected by an elongated member. The first and second members are retracted proximally until the first member abuts an inner surface of the bodily organ and the second member is retracted out of the hole in the bodily organ. Then, the second member is pushed distally into abutment with an outer surface of the bodily organ. A sealing device for sealing a puncture in tissue is also described.
