Outline of Final Research Achievements

For adding a hook to an absorbable suture, a folded suture make it large in diameter, and a partially-cut suture make it brittle. A barbed suture can bring solutions to those problems. In addition, it is stiff enough to be pushed through a guiding needele by itself. To add radio-opaque nature to it, iodine contrast medium or barium sulfate were laid on it. Those radio-opaque sutures were visible on X-ray fluoroscopy image.
In a phantom examination, the radiopaque absorbable suture was easily placed near a target through a guiding needle. It was clearly visible on CT image. The barbed suture could not easily pull out from the phantom.
Therefore, we believe that we can make the guiding marker which is made of the barbed absorbable suture.
