Abstract

Suture devices, particularly useful in endoscopic surgery, include a suture device made of bioabsorbable material having an elongate body member with a sharp distal end for penetrating tissue and means for locking the suture device in tissue to prevent forward and rearward movement and a suture device made of bioabsorbable material having a hinge-like joint for folding a distal portion at a precise location to be juxtaposed with a proximal portion for adjustable locking. Methods of using the suture devices for joining tissue sections, such as in tuboplasty, for closing anatomical lumens and for subcuticular suturing.

Claims

1. A suture needle for joining tissue comprising

an elongate body member having a sharp distal end, a proximal end and a spiral configuration therebetween forming a plurality of coils whereby multiple bites of tissue can be penetrated with said suture needle, said spiral configuration being formed of coils having diameters increasing as they approach said sharp distal end.

2. A suture needle for joining tissue comprising

an elongate body member having a sharp distal end, a proximal end and a spiral configuration therebetween forming a plurality of coils whereby multiple bites of tissue can be penetrated with said suture needle, said spiral configuration being formed of coils having diameters decreasing as they approach said sharp distal end.

3. A suture needle for joining tissue comprising

an elongate body member having a sharp distal end, a proximal end and a spiral configuration therebetween forming a plurality of coils whereby multiple bites of tissue can be penetrated with said suture needle, said spiral configuration being formed of coils disposed in a single plane.
