Self-suturing catheter system

Abstract

An improved catheter-over-needle system having a hub including a self-suturing mechanism comprising a circular needle rotatably slidable in a circular groove in the hub. The needle is sharpened to a point at an end and preferably is also formed into a tang for use as a handle. The hub is flattened on a side to be adjacent to the skin, defining a hub flat thus truncating the groove through, for example 60° thereof. After the catheter is positioned in the blood vessel, the flat is pressed against the skin. The circular needle is rotated through an angle such that the circular needle passes through a portion of the skin, thereby “self-suturing” the hub to the skin of the patient. The hub is thus firmly attached to the patient, and no separate suturing is required. De-suturing of the catheter requires only reverse rotation of the circular needle.
