1. A system for delivery of an implant having an implant lumen to a target position in a body passage, the system comprising:

  • an elongate tubular sheath comprising an elastic material, wherein the tubular sheath is configured to be passed through the body passage while containing the implant in a compressed state inside the sheath, and wherein the sheath has a distal end with an aperture formed therein;

    a catheter having a proximal end and a distal end and a lumen that extends between the proximal end and the distal end, wherein the lumen distends at the distal end thereby forming a compressible distended portion, wherein at least a portion of the catheter is disposed within the implant lumen, and the compressible distended portion is configured to slidably open and slidably obstruct the aperture;

    an ejector configured to move relative to the catheter and to force the implant in a distal direction thus stretching the elastic material of the tubular sheath so as to expand the aperture of the tubular sheath; and

    wherein when the compressible distended portion of the catheter slidably opens the aperture and the aperture expands, the implant is delivered to a target position in a body passage.
