Abstract
The present invention is directed to a delivery catheter assembly for advancing a surgical device to a desired location within a vessel during a surgical procedure. The delivery catheter assembly includes an inner sheath assembly through which the surgical device is advanced to the desired location within the vessel. The delivery catheter assembly further includes an outer sheath assembly surrounding the inner sheath assembly. In accordance with the present invention, at least one of the inner sheath assembly and the outer sheath assembly has an angular configuration at a predetermined time during the surgical procedure. The present invention further includes an adjusting assembly for creating the angular configuration of at least one of the inner sheath assembly and the outer sheath assembly. The adjusting assembly may include at least one pull wire positioned within one of the inner sheath and the outer sheath. Furthermore, the inner sheath assembly is movable with respect to the outer sheath assembly. The inner sheath assembly is capable of moving between an extended position and a retracted position at the predetermined time during the surgical procedure.
