Magnetically Actuated Soft Capsule With the Multimodal Drug Release Function
Design and Characterization Fig. For example, if the applied preload force is 1. Electronics enterjon constantly miniaturized and increase performance. Current status of capsule endoscopy through a whole digestive tract. The system developed by Gora et al[ 6970 ] involves a capsule containing optical frequency domain imaging OFDI technology – a rapidly rotating laser tip emitting a beam of near-infrared light – and sensors that record light reflected back from the oesophageal mucosa.
It is aspired that this will complemented by other sensors, e. This critical condition can be used to implement the drug release in two different modes. Recently, the feasibility of a novel method of controlled colonic insufflation via an untethered capsule in vivo was demonstrated Figure 4 [ 36 ].
So far, this new system has been presented in international scientific meetings and there is data on the effectiveness of the magnetic control system with laboratory simulations[ 57 ] as well as with a phantom colon model[ 58 ].
At the moment, the drug release speed becomes extremely high. Please review our privacy policy.
