## Abstract

Compact medical device inserters, systems incorporating the same, and related methods of use are described. The inserters can include a housing, a sharp support, a sharp body, and a shroud, and can apply a sensor control device to a recipient with a sensor implanted in the recipient's body. The shroud can extend from the sensor control device in a position that covers or protects the sensor and a sharp, and can be retracted by pressure placed upon the inserter against the recipient's body to cause the sharp and sensor to penetrate the body, after which the sharp can be automatically withdrawn with the aid of a biasing element.

## Claims

### Claim 1

A system for inserting an analyte sensor into a human body, comprising:
a sensor control device coupled with an analyte sensor and having an anterior surface; and
an inserter comprising:
a housing having a posterior side adapted to be held by a user and an anterior side adapted to receive the sensor control device;
a sharp; and
a shroud having an anterior surface and adapted to slide with respect to the housing from an extended position that covers the analyte sensor and the sharp to a retracted position that exposes the analyte sensor and the sharp,
wherein the sensor control device has an opening through which the shroud can pass, wherein the shroud is held in the extended position by a first lock mechanism comprising a structure on the shroud that locks with a structure on the sensor control device, and wherein, in the extended position, the anterior surface of the shroud extends through the opening and anterior to the anterior surface of the sensor control device.

### Claim 2 (depends on 1)

The system of claim 1, wherein the structure on the shroud is a detent and the structure on the sensor control device is a recess.

### Claim 3 (depends on 1)

The system of claim 1, wherein the sharp is coupled with a posterior mount.

### Claim 4 (depends on 3)

The system of claim 3, wherein the inserter further comprises a biasing element, and wherein the biasing element contacts a base of the shroud and a surface on the posterior mount, and is adapted to apply the force therebetween.

### Claim 5 (depends on 4)

The system of claim 4, wherein the biasing element is in an uncompressed state when the shroud is extended.

### Claim 6 (depends on 4)

The system of claim 4, further comprising a second lock mechanism, wherein the biasing element is held in the uncompressed state by the second lock mechanism.

### Claim 7 (depends on 6)

The system of claim 6, wherein the second lock mechanism comprises an elastic arm coupled with the housing and is adapted to releasably hold the posterior mount in position with respect to the sensor control device.

### Claim 8 (depends on 3)

The system of claim 3, wherein the inserter further comprises two elastic arms coupled with the housing and adapted to releasably hold the posterior mount in position with respect to the sensor control device.
