Abstract
Abstract The invention provides endoluminal coil delivery systems and methods for positioning a coil within a body lumen. In particular, the device uses a mechanical latch in the form of jaws to positively engage the coil during positioning. The coil may be restrained in a straight configuration from within the coil, using an internal coilwire, or from outside using a catheter. Thus, the mechanism for releasing the coil to form its relaxed convoluted shape is separate from the mechanism for disengaging the coil from the delivery system. The use of an internal core wire allows a coil having a helical outer surface to be torqued against a fallopian tube or other body lumen wall, thereby firmly anchoring the coil in the target position prior to disengaging the delivery system.
