DEFINITION

Classification: 604/503

Therapeutic material introduced or removed in response to a sensed body condition:

(under subclass 500) Subject matter for a process wherein the material's introduction into or withdrawal from the body is in response to specific detected condition of the body.

(1) Note. Patents in this subclass disclose methods where the condition governs the application or withdrawal of material to or from body. For example, an irregular heartbeat can be sensed by an EKG machine, which in turn actuates an infusion syringe to supply a drug, which corrects the irregularity.
