Abstract
An improved, disposable, inexpensive vessel holder suitable for use in coronary artery surgery for impaling the cut end of a vessel graft on three sharpened wire prongs, two if that can be made to extend laterally for holding the cut end of the graft in an open position for suturing to the obstructed coronary artery, is disclosed.
Claims16
A generally cylindrical elongate vessel holder, having a generally linear center line, for holding a vessel graft during bypass surgery comprising three sharp wire prongs on which the cut end of the graft may be impaled, two of which prongs extend outwardly from the center line and one of which prongs extends substantially along the center line.
A generally cylindrical elongate vessel holder, having a generally linear center line, for holding a vessel graft during bypass surgery comprising two sharp wire side prongs and a sharp central prong, on which the cut end of the graft may be impaled, the central prong extending axially beyond the two side prongs.
A generally cylindrical elongate vessel holder, having a generally linear center line, for holding a vessel graft during bypass surgery comprising of two sharp wire side prongs and a sharp wire central prong on which the cut end of the graft may be impaled, the central prong constructed and disposed to lie between the two side prongs and adjacent the holder.
A generally cylindrical elongate vessel holder, having a generally linear center line, for holding a vessel graft during bypass surgery comprising of three sharp wire prongs, on which the cut end of the graft may be impaled and heat shrunk tubing holding the wire prongs together.
A vessel graft holder (10) comprising three wire members (20, 30 and 40), two of the wires (20 and 30) having angled hooks formed thereon, respectively, by bends 22 and 32 on the ends thereof, the hooks extending in opposite directions relative to each other and being sharpened to needle like points (24 and 34), and having bends therein (26 and 36) a distance from said hooks, the third wire (40) having first, second and third bends (42, 44 and 46) and having a sharpened tip (48), the bends (42, 44 and 46) being so formed that the sharp needle-like point (48) lies at an angle of approximately 45.degree. with respect to the wire (40) immediately before the first bend (42), the wires being secured into a bundle by heat shrunk tubing (50).
A vessel graft holder (10) comprising three wire members (20, 30 and 40), two of the wires (20 and 30) having angled hooks formed thereon, respectively, by bends 22 and 32 on the ends thereof, the hooks extending in opposite directions relative to each other and being sharpened to needle like points (24 and 34), and having bends therein (26 and 36) a distance from said hooks, the third wire (140) having first and third bends (142 and 144 and having a sharpened tip (146), the bends (142 and 144) being so formed that the sharp point (146) extends distally of the instrument approximately parallel to the wire (140) immediately before the first bend (142), the wires being secured into a bundle by heat shrunk tubing (50).
