## Abstract

Ambulatory infusion pumps, durable assemblies, and disposable assemblies, including energy sources, reservoirs, baseplates, and related components therefor, as well as component combinations and related methods.

## Claims

### Claim 1

A disposable assembly, comprising:
a baseplate;
a medicament reservoir on the baseplate;
a plunger moveable within the reservoir;
a motor rotor included in the disposable assembly, the motor rotor configured to rotate based on electromagnetic energy received from outside the disposable assembly; and
a gear train entirely included in the disposable assembly, the gear train configured to transform rotation of the motor rotor into mechanical forces that move the plunger.

### Claim 2 (depends on 1)

A disposable assembly as claimed in claim 1, wherein
the disposable assembly does not include a motor stator.

### Claim 3 (depends on 1)

A disposable assembly as claimed in claim 1, wherein
the motor rotor comprises a disc that is parallel to the baseplate.

### Claim 4 (depends on 1)

A disposable assembly as claimed in claim 1, wherein
the motor rotor is disc-shaped.

### Claim 5

An infusion pump disposable assembly for use with an infusion pump durable assembly, the infusion pump durable assembly including a motor coil comprising coil windings, the infusion pump disposable assembly comprising:
a baseplate;
a motor rotor included in the infusion pump disposable assembly, the motor rotor defining an axis of rotation that is perpendicular to the baseplate; and
a gear train entirely included in the infusion pump disposable assembly, the gear train configured to transform rotation of the motor rotor into linear movement;
wherein the baseplate is configured to be mounted adjacent to the infusion pump durable assembly in such a manner that energization of the motor coil causes the motor rotor to rotate without direct mechanical coupling or electrical connection.

### Claim 6 (depends on 5)

An infusion pump disposable assembly as claimed in claim 5, further comprising:
a medicament reservoir on the baseplate; and
a plunger operably connected to the gear train and moveable within the reservoir.

### Claim 7 (depends on 5)

An infusion pump disposable assembly as claimed in claim 5, wherein
the disposable assembly does not include a motor stator.

### Claim 8 (depends on 5)

An infusion pump disposable assembly as claimed in claim 5, wherein
the motor rotor is disc-shaped.

### Claim 9

An infusion pump disposable assembly for use with an infusion pump durable assembly, the infusion pump durable assembly including a motor coil comprising coil windings, the infusion pump disposable assembly comprising:
a baseplate;
a motor rotor included in the infusion pump disposable assembly, the motor rotor defining an axis of rotation that is perpendicular to the baseplate and configured to rotate, when the baseplate is mounted adjacent to the infusion pump durable assembly, in response to energization of the motor coil without direct mechanical coupling or electrical connection; and
means, entirely included in the infusion pump disposable assembly and operably connected to the motor rotor, for driving a plunger located within a medicament reservoir in response to rotation of the motor rotor.

### Claim 10 (depends on 9)

An infusion pump disposable assembly as claimed in claim 9, wherein
the medicament reservoir is on the baseplate.

### Claim 11 (depends on 9)

An infusion pump disposable assembly as claimed in claim 9, wherein
the disposable assembly does not include a motor stator.

### Claim 12 (depends on 9)

An infusion pump disposable assembly as claimed in claim 9, wherein
the motor rotor is disc-shaped.

### Claim 13

A method comprising the step of:
mounting a disposable assembly, including a baseplate, a motor rotor included in the disposable assembly and defining an axis of rotation that is perpendicular to the baseplate, and a gear train entirely included in the disposable assembly and configured to transform rotation of the motor rotor into linear movement, to a durable assembly, including an energy supply, a motor coil comprising coil windings, and a processor configured to control power to the motor coil, in such a manner that energization of the motor coil causes the motor rotor to rotate without direct mechanical coupling or electrical connection.

### Claim 14 (depends on 13)

A method as claimed in claim 13, wherein
the disposable assembly includes a medicament reservoir and a plunger operably connected to the gear train and moveable within the reservoir.

### Claim 15 (depends on 13)

A method as claimed in claim 13, wherein
the disposable assembly does not include a motor stator.

### Claim 16 (depends on 13)

A method of claim 13, wherein the processor of the durable assembly is configured to detect a rotational position or speed of the motor rotor of the disposable assembly.
