first embodiment
[0079] FIGS. 7A-G illustrate numerous embodiments of the heater puller of FIG. 6. FIG. 7A illustrates a heater puller. Plier-type heater puller 80 comprises coupler 82 and actuator 83. Coupler 82 includes two gripping surfaces 84 that conform to the shape of the proximal end of heater 16. Actuator 83 includes two handles 86a and 86b, each having a distal end that is coupled rigidly to one of the gripping surfaces, and pivot 88 about which the handles rotate. When the proximal ends of handles 86 are urged apart, handles 86 pivot about pivot 88 so that gripping surfaces 84 also move away from each other. Similarly, when the proximal ends of the handles are urged together, so too are the gripping surfaces. Thus, when a heater is placed between the gripping surfaces, heater puller 80 may be engaged securely to the heater by squeezing the handles together. While the heater puller is engaged to a heater, an operator can pull the heater from or push a heater into a TSU.

second embodiment
[0082]FIGS. 7C and 7D illustrate the heater puller. Ferrule-type heater puller 100 comprises sliding sleeve 102, ferrule 104 disposed at the distal end of sliding sleeve 102, center rod 106, and grips 108 that are mounted on compliant extensions 109 of center rod 104. Center rod 106 and grips 108 may be advanced into and out of center bore 110, which extends from the proximal end of sliding sleeve 102 to the distal end of ferrule 104, to respectively close and open grips 108. To open grips 108 (as shown in FIG. 7D), center rod 106 is advanced towards the distal end of sliding sleeve 102. The compliance of extensions 109 allows a heater to be inserted between grips 108. Sliding sleeve 102 and ferrule 104 then may be actuated in the distal direction towards heater 16 to close grips 108. Ferrule 104 engages compliant extensions 109, contracting the extensions (and thus grips 108) around heater 16 and thereby securely engaging the heater to heater puller 100. While the heater puller is ...
third embodiment
[0084] FIGS. 7E-F illustrates a heater puller. Notch-type heater puller 120 comprises actuator 122 and coupler 124 having one or more L-shaped slots 126. Each slot 126 incorporates detent 128 to slide past associated pin 130 disposed on the proximal end of heater 16. This permits pin(s) 130 to engage coupler 124 with reduced rotation. While the heater puller is engaged to the heater, an operator can pull the heater from or push a heater into a TSU. FIG. 7F provides an end view of heater 16 with two pins 130.
