A device and method for cannula insertion into a users tissue are disclosed. A patch pump comprising a non-linear needle path with a first bend may be provided. A rigid needle may be located in the needle path and may be composed of a material that allows the rigid needle to maintain a bend at the first bend when traversing the non-linear needle path. A movement mechanism may be configured to apply force on a first end of the rigid needle to cause the rigid needle to traverse the non-linear needle path from a first needle position to a second needle position. A cannula may receive a force from a second end of the rigid needle when the movement mechanism applies the force on the first end of the rigid needle and configured to traverse from a first cannula position to a second cannula position based on the force.
