A collection of devices which includes an invasive cannula/needle, intended for both harvesting fat tissue from a patient (liposuction) and subsequently injecting the fat tissue into the patient from whom it was taken (autologous lipotransfer) as part of a surgical procedure (e.g., reconstructive/cosmetic, orthopaedic, spinal); it may additionally be intended to process the adipose tissue. In addition to needles/cannulae, it includes syringes, accessories (e.g., caps, connectors), and may include collection/processing devices (e.g., filtration bag). This is a single-use device.
