The first compartment includes a first wall that includes a first ferrous material, and the first wall is configured to disintegrate and release the first substance into a patient in response to first electromagnetic radiation received by the first ferrous material. The medical delivery device also includes a second compartment attached to the first compartment and configured to hold a second substance. The second compartment includes a second wall that includes a second ferrous material, and the second wall is configured to disintegrate and release the second substance into the patient in response to second electromagnetic radiation received by the second ferrous material. ## Claims ### Claim 1 A medical delivery device comprising: a first compartment configured to hold a first substance, wherein the first compartment includes a first wall that is composed at least in part of a first ferrous material and at least in part of a first acid or a first base, and wherein the first wall is configured to disintegrate and release the first substance into a patient in response to heating of the first acid or the first base that results from first electromagnetic radiation received by the first ferrous material; and a second compartment attached to the first compartment and configured to hold a second substance, wherein the second compartment includes a second wall that is composed at least in part of a second ferrous material and at least in part of a second acid or a second base, and wherein the second wall is configured to disintegrate and release the second substance into the patient in response to heating of the second acid or the second base that results from second electromagnetic radiation received by the second ferrous material. ### Claim 2 (depends on 1) The medical delivery device of claim 1, further comprising: an electromagnetic radiation source; and a controller in communication with the electromagnetic radiation source, wherein the controller is configured to emit the first electromagnetic radiation to cause release of the first substance at a first time and to emit the second electromagnetic radiation to cause release of the second substance at a second time that is after the first time. ### Claim 3 (depends on 2) The medical delivery device of claim 2, wherein the first substance and the second substance are the same dose of a same medicine. ### Claim 4 (depends on 2) The medical delivery device of claim 2, wherein the first substance comprises a first dose of a medicine and the second substance comprises a second dose of the medicine, and wherein the second dose is larger than the first dose. ### Claim 5 (depends on 2) The medical delivery device of claim 2, wherein the first substance comprises a first type of medicine and the second substance comprises a second type of medicine that is different from the first type of medicine. ### Claim 6 (depends on 1) The medical delivery device of claim 1, wherein the first compartment includes a barrier that forms a first sub-compartment and a second sub-compartment, wherein the first sub-compartment includes the first substance and the second sub-compartment includes a third substance, and wherein the barrier is configured to disintegrate in response to third electromagnetic radiation such that the first substance mixes with the third substance prior to being released into the patient. ### Claim 7 (depends on 1) The medical delivery device of claim 1, wherein the first wall is at least a portion of a capsule that contains the first substance. ### Claim 8 (depends on 1) The medical delivery device of claim 1, wherein the first wall is formed from a biocompatible plastic that includes the first ferrous material and the first acid or the first base. ### Claim 9 (depends on 1) The medical delivery device of claim 1, wherein the first ferrous material comprises a first type of ferrous material and the second ferrous material comprises a second type of ferrous material that differs from the first type of ferrous material. ### Claim 10 (depends on 1) The medical delivery device of claim 1, wherein the first ferrous material comprises a first amount of a ferrous material and the second ferrous material comprises a second amount of the ferrous material that differs from the first amount. ### Claim 11 (depends on 1) The medical delivery device of claim 1, wherein the second substance comprises a marker substance that is used to perform internal imaging of the patient. ### Claim 12 (depends on 1) The medical delivery device of claim 1, wherein the first substance comprises a mixture of a first drug and a second drug. ### Claim 13 (depends on 1) The medical delivery device of claim 1, wherein the first electromagnetic radiation has a first intensity and the second electromagnetic radiation has a second intensity that is greater than the first intensity. ### Claim 14 (depends on 1) The medical delivery device of claim 1, wherein disintegration of the first wall causes the first compartment to detach from the second compartment. ### Claim 15 (depends on 1) The medical delivery device of claim 1, wherein the first compartment also includes one or more walls that do not include the first ferrous material. ### Claim 16 A method of forming a medical delivery device, comprising: forming a first compartment configured to hold a first substance, wherein forming the first compartment includes forming a first wall of the first compartment that is composed at least in part of a first ferrous material and at least in part of a first acid or a first base, and wherein the first wall is configured to disintegrate and release the first substance into a patient in response to heating of the first acid or the first base that results from first electromagnetic radiation received by the first ferrous material; forming a second compartment configured to hold a second substance, wherein forming the second compartment includes forming a second wall that is composed at least in part of a second ferrous material and at least in part of a second acid or a second base, and wherein the second wall is configured to disintegrate and release the second substance into the patient in response to heating of the second acid or the second base that results from second electromagnetic radiation received by the second ferrous material; and attaching the second compartment to the first compartment to form the medical delivery device. ### Claim 17 (depends on 16) The method of claim 16, further comprising placing the first substance into the first compartment and placing the second substance into the second compartment. ### Claim 18 (depends on 16) The method of claim 16, further comprising forming a barrier in the first compartment to make a first sub-compartment and a second sub-compartment, wherein the first sub-compartment includes the first substance and the second sub-compartment includes a third substance, and wherein the barrier is configured to disintegrate in response to third electromagnetic radiation such that the first substance mixes with the third substance prior to being released into the patient. ### Claim 19 (depends on 16) The method of claim 16, further comprising forming one or more additional walls of the first compartment such that the one or more additional walls do not include the first ferrous material. ### Claim 20 (depends on 16) The method of claim 16, wherein the first ferrous material comprises a first amount of ferrous material and the second ferrous material comprises a second amount of the ferrous material, and wherein the second amount of the ferrous material is greater than the first amount of the ferrous material.
