Medical device for transcutaneously inserting an insertable element into a body tissue

A medical device for performing a transcutaneous insertion into a body tissue, wherein the medical device comprises:

• an insertable element, wherein the insertable element is flexible and includes an in vivo distal end for subcutaneous insertion and an ex vivo proximal end;
• an insertion cannula for subcutaneously inserting the insertable element, the insertion cannula having a lumen which fully or partially is enclosed by a wall of the insertion cannula, wherein the insertable element is received in the lumen, wherein the wall comprises at least one shape memory alloy, wherein the insertion cannula is stored in a first shape configuration, and wherein the insertion cannula is configured to be transformable into a second shape configuration for insertion,
• wherein the in vivo distal end of the insertable element adopts a first shape corresponding to the first shape configuration when the insertion cannula is in the first shape configuration and the in vivo distal end of the insertable element adopts a second shape corresponding to the second shape configuration when the insertion cannula is transformed into the second shape configuration for insertion;
• and
• a patch configured to be mounted onto the skin of a user wherein the insertion cannula is configured such that the insertion cannula is withdrawn into the patch after insertion of the insertable element and the insertable element is configured to stay at least partially within the body tissue after the insertion cannula is withdrawn into the patch.
