An implantable extravascular pressure sensing system including a cuff having a first brace portion, a second brace portion, and a plurality of biasing members movably coupling the first brace portion and the second brace portion to each other, the first brace portion defining a fluid chamber, the fluid chamber defining a recessed aperture, a flexible diaphragm coupled to the fluid chamber and sealing the recessed aperture, a fluid disposed within the fluid chamber for exhibiting a hydraulic pressure in communication with the flexible diaphragm, and a pressure sensor coupled to the first brace portion, the pressure sensor being configured to measure a change in the hydraulic pressure when a force is imparted on the flexible diaphragm.

Extravascular cuff

A method of monitoring respiration with an acoustic measurement device, the acoustic measurement device having a sound transducer, the sound transducer configured to measure sound associated with airflow through a mammalian trachea, the method includes correlating the measured sound into a measurement of tidal volume and generating at least one from the group consisting of an alert and an alarm if the measured tidal volume falls outside of a predetermined range.

Acoustic sensor and ventilation monitoring system

A tissue punch including a barrel defining a first open end, a second open end, and inner diameter, an outer diameter, and a lumen there through. A piston is at least partially disposed within the lumen and pressed against the inner diameter of the barrel, the piston being configured to create negative pressure within the barrel when the piston is retracted. A cutting element defines a proximal end and a distal end, the proximal end of the cutting element being disposed at the second open end of the barrel, the distal end of the cutting element defining a cutting edge, the cutting element is in fluid communication with the barrel. A pushing element is slideably disposed about the outer diameter of the barrel, the pushing element is movable from a biased first position away from the cutting edge to a second position proximate the cutting edge.
