Abstract
An inflated balloon (5) implanted in a patient (3) is provided with a high-frequency receiver system (7) wherein an electric current is induced upon the generation of a high-frequency, electromagnetic field outside the patient which electric current activates a puncturing device, such as an electric resistor element (11), in the balloon (5).
Claims14
A method of performing puncturing work on an inflated balloon-like object (5) implanted in a patient characterized in that the balloon-like object (5) is provided with a high-frequency receiver system (7), that a high-frequency electromagnetic field is produced in proximity to the patient which field is capable of penetrating into the patient and producing an electric current in the receiver system, and that said current is caused to activate a puncturing device (11) in the balloon-like object.
In combination with an inflatable balloon which can be implanted in a patient's body, an apparatus for puncturing said balloon when in an inflated condition and when in a patient's body, said apparatus comprising
- an electrically-activatable puncturing means located in said balloon,
- a high-frequency receiver system located in said balloon and connected to said electrically-activatable puncturing means,
- an antenna coil which is positionable near the patient's body, and
- a high-frequency generator connected to said antenna coil, said high-frequency generator causing said antenna coil to emit a high-frequency electromagnetic field which causes said high-frequency receiver system to generate an electric current which causes said puncturing means to puncture the balloon.
