Appeal 2007-2812
Application 10/337,236
5. The magnet 27 is encased in an inert housing 29 (Anderson, at col. 6, ll.
11-14) which is shown in Fig. 3 to be dome-shaped.
6. The stylet 23 is inserted into the throat of the patient and then guided into
the trachea using an external magnet 41 (Anderson, at col. 6, ll. 27-46 and
Figs. 5-7).
7. The stylet 23 comprising the magnet 27 is “responsive to the external
magnet” and is guided by an external magnet into the trachea (Anderson, at
col. 4, ll. 33-66).
Application of Anderson to the claims
8. The main body 25 of the stylet 23 is an “elongate wire” (Findings of Fact
(“FF”) 3; Anderson, at col. 6, ll. 5-7 and Fig. 2) as recited in claim 1.
9. The inert housing 29 of Anderson’s stylet 23 is a hollow cylinder (FF 5;
Anderson, at col. 6, ll. 11-14 and Fig. 3) attached to the end of the stylet 23,
satisfying the limitation of claim 1 of a “hollow cylinder secured on the
distal end of the wire forming the tip of the guidewire.” (See Final Office
Action 3.)
10. A magnet 27 which is “responsive” to an external magnet (FF 6, 7;
Anderson, at col. 4, ll. 33-66) is “encased in the inert housing” (FF 5;
Anderson, at col. 6, ll. 11-14), meeting the limitation in claim 1 of a
“magnetically responsive element inside said hollow cylinder.” (See Final
Office Action 3.)
11. The inert housing 29 has a dome-shaped end (FF 5; Anderson, at col. 6,
ll. 11-14 and Fig. 3) which holds the magnet as required by the recitation in
claim 1 of a “dome-shaped cap securing the magnetically responsive
element inside the hollow cylinder.” (See Final Office Action 3.)
