Please help me, "Frances Hector entered Cedars-Sinai Medical Center (Cedars-Sinai), Los Angeles, California, for a surgical operation on her heart. During the operation, a pacemaker was installed in Hector. The pacemaker, which was manufactured by American Technology, Inc., was installed at Cedars-Sinai Medical Center by Hector's physician, Dr. Eugene Kompaniez. The pacemaker was defective, causing injury to Hector. Hector sued Cedars-Sinai Medical Center under Article 2 (Sales) of the UCC to recover damages for breach of warranty of the pacemaker. Hector alleged that the surgical operation was primarily a sale of a good and therefore covered by the UCC.

-Cedars-Sinai Medical Center argued that the surgical operation was primarily a service and therefore the UCC did not apply. Who wins?
