摘要： Provided is a micro electro mechanical systems (MEMS) device for use with an elongate structure. The MEMS device includes a generally planar substrate, a device wall layer formed upon the substrate, a septum cavity formed in the device wall layer, a channel formed in the device wall layer in fluid communication with the septum cavity, and a septum element disposed in the septum cavity. The septum element is formed of a viscoelastic material. The septum element defines a septum entry surface and a septum exit surface with the septum exit surface being exposed to the channel and disposed between the septum entry surface and the channel. The septum element is without any openings formed through the septum element extending between the septum entry and exit surfaces. Methods of manufacturing and interacting with the MEMS device are also provided.

摘要： A self-monitoring catheter system may detect an obstruction during use of a catheter. The system may include a catheter with an interior lumen that has one or more ports into the lumen; a first and a second electrode; and an impedance measurement instrument that measures changes in the impedance between the first and the second electrodes after the first electrode is exposed to fluid within the catheter lumen, thereby signaling an obstruction during use of the catheter.
