angle of deflection required by the suture to feed into the memory loop as with the previously described embodiment it should be noted that the delivery retrieving wire loop first projects outward away from the distal end of the guide tube then rearward back toward the guide tube where it will be intersected by a suture or other flexible element fed through the upper curved guide the apparatus can be designed for easy assembly and disassembly to allow cleaning and sterilization of the individual pieces for example in the embodiment shown in fig1 31 the proximate end 48 of the delivery retrieval wire loop member is inserted into the socketed end of the plunger 44 plunger 44 is slid into the bore of the chassis barrel 42 and has its distal end or stem 78 press or snap fitted into the shallow socket 80 of the rear end portion of the handle loop 60 the guide tip 51 including the distal conduit 56 can have the wire loop threaded through them and be snugly inserted into the distal opening of the chassis barrel 42 with the side key 108 of the tip received in the keyway 76 disassembly is achieved by the reverse procedure whereupon the lumen or lumens of the housing structure can be cleaned by forced air or an appropriate cleaning liquid and or by an ultrasonic cleaner a small pipe cleaner can be used as necessary the goal being that smooth consistent operation is achieved following sterilization.
