Abstract
Assemblies and methods for delivering an implant to a patient are disclosed. A delivery assembly can comprise an elongate tube, an outer magnetic member, and an inner magnetic member. The elongate tube extends from a proximal end portion to a distal end portion and defines a delivery lumen. The outer magnetic member can be movable along an outer surface of the tube; the inner magnetic member can be positioned within the delivery lumen and magnetically coupled to the outer magnetic member through a sidewall of the tube. The inner magnetic member can be movable through the delivery lumen when actuated by relative movement between the outer magnetic member and the tube. The delivery assembly can further comprise a syringe or an inflator/deflator couplable to a hub at the proximal end portion of the tube. The syringe or inflator/deflator can be used to urge fluid against a proximal end portion of the inner magnetic member.
