Abstract
A medical device including at least one reservoir, adapted to contain a material, such as a therapeutic agent, and sealed by a cover. The reservoir is openable, so as to release the material, for example, by (i) disintegration of the cover, (ii) movement of the cover to an open position, and/or (iii) a change of composition or properties of the cover allowing the material to pass therethrough. The power required to open the reservoir is provied by a current induced in a coil associated with the medical device by a change in magnetic flux in the area of the medical device.
Claims19
A medical device comprising:
- at least one primary coil;
- at least one reservoir adapted to contain a material, said at least one reservoir connected to or embedded in the at least one primary coil;
- a cover configured to seal the at least one reservoir in a first state of the cover and to allow the material to exit the at least one reservoir in a second state of the cover;
- and wherein said cover is configured such that it transitions between the first and second states when said coil is exposed to a magnetic flux.
