Document Type and Number:
Japanese Patent JPH10504481
Kind Code:
A
Abstract:
An apparatus and method for reducing the circumference of a vascular structure comprising the steps of providing a plurality of sutures and a plurality of discrete suture support segments of a biocompatible, inert material, each suture support segment having at least two suture holes spaced a predetermined distance (D) apart; individually suturing each discrete suture support segment to the vascular structure with one of the plurality of sutures by effecting a horizontal mattress (U-shaped) suture along the vascular structure through a length of tissue of the vascular structure such that the length (D') of tissue sutured is greater than distance (D); and tightening and tying off the suture, whereby each sutured suture support segment creates an imbrication in the vascular structure, thereby reducing the circumference thereof. A biocompatible, inert stabilizing material may optionally be affixed over the suture support segments and the vascular structure after prior to tying off the suture to stabilize the interval between the suture support segments and eliminate direct exposure of the segmented apparatus to blood.
