A flexible medical needle for extended indwelling periods is provided. The medical needle apparatus includes a spine body and a flexible shaft portion. The spine body has a length between a first end, comprising a piercing tip, and a second end. The flexible shaft portion may be disposed on at least a portion of the spine body, forming a needle shaft having a passage along a portion of the length of the spine body. The spine body may also be coiled forming an axial passage within the spine body. In this latter embodiment, the flexible shaft portion surrounds the spine body. In each embodiment, the spine body is configured to facilitate bending, allowing for the medical needle to remain indwelling with reduced discomfort.

A delivery system having a telescoping spring is used to drive a plunger. The telescoping spring includes a nested inner spring that uses the unused volume on the inside of an outer spring. The telescoping spring has a staged release of each spring. The inner spring is connected to a non-anchored end of the outer spring, and rides within a container located within an inner dimension of the outer spring. The spring constant K of each spring can be the same or different. The delivery system can be fully mechanical or implemented as a smart delivery system under electronic control.

Occlusion sensor systems and methods of using the occlusion sensor systems are provided. In a general embodiment, the present disclosure provides a sensor device includes a tube and an infra-red reflective sensor comprising an infra-red light emitter and an infra-red phototransistor receiver or photo-diode. The infra-red reflective sensor and the infra-red phototransistor receiver or photo-diode are positioned at or near the tube so that an infra-red light can be transmitted to a portion of the tube and at least a portion of the infra-red light reflected off the portion of the tube can be detected by the infra-red phototransistor receiver or photo-diode.
