Abstract: Intravascular implant delivery systems and methods are described. One such system carries an implant by retaining an engagement member engaging the implant in a position proximal of an aperture at a distal end of the delivery system. The engagement member is retained proximal to the aperture by a cord that obstructs the movement of the engagement member through the aperture. The engagement member is free to rotate and move within an area defined by the delivery system, allowing the implant to react to forces imparted to the implant by the movement of the delivery system and implant through a delivery catheter. Once the implant is in a desired implant position, the cord is moved away from an aperture and the engagement member is allowed to move away from the delivery system.

Abstract: The invention relates to a cage-type intervertebral implant that is made up of a dished side wall (1), a cambered side wall (2), a front part (3), a rear part (4) and at least one intermediate wall (5, 6), thus comprising at least two cavities (7, 8, 9). An upper and a lower cage surface (10, 11) include a first lordosis angle (&agr;1) in the direction front part—rear part and a second lordosis angle (&agr;2) perpendicular thereto, said cage surfaces (10′, 11) intersecting outside the cage. The cage structure is characterized by a double-wedge geometry (double-wedge-shaped cage) that is defined by the two lordosis angles (&agr;1) and (&agr;2) and that advantageously adapts itself to the anatomical conditions in the intervertebral area. The cage is further characterized by a high moment of tilt that effectively counteracts a tipping of the cage.
