Abstract:
1. A tissue closing device for closing an opening penetrating a tissue membrane in a living body, comprising: a closure configured to close the opening, the closure comprising a seal portion for covering the opening and tissue membrane surrounding the opening from one side of the tissue membrane, a deformation portion which is deformable, and a connecting portion connecting the seal portion and the deformation portion, the seal portion having a first longer axis and a second shorter axis and the seal portion being directly supported by the connecting portion at two points along the second shorter axis; and an arrangement device detachably retaining the closure for arranging the closure in the living body; the arrangement device comprising: a storing member having a longitudinal axis comprising a storing portion and a support portion, the storing member being configured for passage through the opening, the support portion comprising a take-out port which is divisible into a plurality of portions and configured to be opened from a closed state, the support portion being located on the distal side of the storing portion and supporting the connecting portion at a region between the deformation portion and the seal portion when the take-out port of the support portion is in a closed state, the closure being retained by the arrangement device so that the deformation portion is stored in the storing portion and the seal portion is located on the distal side relative to the support portion; and a hand-operated portion provided on the proximal side of the storing member; wherein the connecting portion passes through a passage of the seal portion and exits from the passage at two openings spaced apart from each other along the second shorter axis of the seal portion, and the connecting portion passes through the deformation portion; wherein the support portion possesses a pair of through holes which communicate the storing portion with the exterior of the storing member and a slit which communicates with the pair of through holes, the take-out port is opened by opening of the slit and closed by closing of the slit such that the connecting portion is retained within the pair of through holes and prevented from movement outside of the through holes along an axis transverse to the longitudinal axis of the storing member when the take-out port is in the closed state, and wherein the pair of through holes support the connecting portion so that the seal portion is pivotally turnable in a single plane around a predetermined one of three mutually orthogonal axes relative to the storing portion when the take-out port is in the closed state, with the deformation portion being discharged exterior of the storing member by opening of the take-out port.
