Abstract
For percutaneous fixation of a hollow organ of a body, a hollow needle carrying a retaining device attached to a tension filament through the skin into the hollow organ, the retaining device is released from the needle, and the organ is fixed by adjusting the tension on the filament and clamping the filament outside the body by means bearing upon the exterior of the body.
Claims4
A method for the fixation of a hollow organ of a living body to a body wall comprising:
- percutaneously inserting a rigid hollow needle carrying a retaining device attached to a trailing tension filament, through the skin, from outside the body, into said hollow organ in the manner that a portion of said trailing tension filament remains outside of the body,
- said retaining device having a portion adapted to engage and apply pressure to an interior wall of said hollow organ,
- releasing said retaining device within said hollow organ from said needle,
- pulling a portion of said trailing tension filament from outside the body to draw said retaining device against the interior wall of said hollow organ to pull said organ against the body wall, and
- fixing said organ by adjusting the tension on said filament and clamping said filament outside the body by means bearing upon the exterior of the body.
A percutaneous fixation device suitable to fix the position of a hollow organ within a body which comprises:
- a hollow needle;
- and
- a "T" head, wherein said head comprises a stiff hollow tube having a hole in its side, a root mass of resinous material larger than said hole disposed within said tube, a tension filament attached to the mid-portion of said head, said head dislodgedly held within said needle, said filament extending through said hole and bonded to said mass, with said filament extending back with said needle, and means threaded on said filament for bearing with compression against the body to apply tension to said filament to draw said head against the inner surface of said hollow organ.
A retaining element adapted for insertion by a needle and eventual removal through the passage formed by said needle, comprising an elongated stiff head, a primary flexible tension filament secured to said head, and a secondary tension filament secured to an end of said head, adapted to be pulled upon to withdraw said head end-wise upon release of tension on said first tension element.
