CONTROLLABLE SENSOR INSERTION NEEDLE
First Claim
1. An insertion device for inserting a subcutaneous device for detecting an analyte into body tissue, comprising:
- an insertion aid having a base body for insertion into the body tissue; and
a subcutaneous device;
wherein the insertion device is configured to generate an adjustable holding force between the base body and the subcutaneous device, the holding force being configured to hold the subcutaneous device against the base body during insertion into the body tissue, and the holding force being adjustable after the insertion such that the subcutaneous device is detachable from the base body.

Abstract
An insertion device is proposed for at least partly inserting a subcutaneous device, more particularly a subcutaneous sensor for detecting at least one analyte, into body tissue. The insertion device has at least one insertion aid and at least one subcutaneous device. The insertion aid has at least one substantially rigidly designed base body, more particularly an insertion needle, for insertion into the body tissue. The insertion device is designed to generate an adjustable holding force between the base body and the subcutaneous device. The insertion device is designed to set the holding force during the insertion such that the subcutaneous device is held against the base body. The insertion device is furthermore designed to set the holding force after the insertion such that the subcutaneous device is detachable from the base body.

19. A method of inserting a subcutaneous sensor into body tissue, comprising:
-
providing an insertion aid having a base body; providing a subcutaneous sensor; generating an electrostatic or magnetic holding force to hold the base body against the subcutaneous sensor; inserting the subcutaneous sensor into the body tissue with the insertion aid while the holding force holds the subcutaneous sensor against the base body; adjusting the holding force after the insertion; and detaching the subcutaneous sensor from the base body. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
