Mechanical resection instruments with outflow control. At least some of the example embodiments are methods including: receiving an indication of a first rotational mode of a mechanical resection instrument coupled to a motor of a motor drive unit (MDU); controlling rotation of the rotating portion of the mechanical resection instrument by controlling the motor, the controlling in conformance with the indication of the first rotational mode; setting a first outflow rate through the mechanical resection instrument based on the indication of the first rotational mode; drawing fluid through the mechanical resection instrument at the first outflow rate during a surgical procedure, the drawing by way of the pump controlled by the controller; sensing a parameter indicative of resection by the mechanical resection instrument; and changing a rate at which fluid is drawn through the mechanical resection instrument, the changing relative to the first outflow rate.

Embodiments relate to an implantable device for detecting leakage of matter from a mammalian lumen, the device comprising a mesh structure that is attachable to a lumen of a mammalian. The mesh structure comprises a material or a material composition that is electrically conductive and which is measurably responsive in terms of its electrical conductivity when being subjected to leakage of matter from the lumen.

A medical implant including an anchor portion including a plurality of arms adapted to engage an internal tissue wall of a body from two opposite faces, wherein the anchor portion is configured such that at least one of the arms does not have an entirely overlapping arm on the other side of the wall and an opening portion adapted to define an opening for blood flow through the internal tissue wall, when the anchor portion engages the wall.

A system for controlling reperfusion in a blood vessel of a patient including a flexible elongated member configured and dimensioned for insertion in the vessel of the patient, the elongated member having a proximal portion and a distal portion, the elongated member configured for insertion so the distal portion extends distal of a clot in the blood vessel. A sensor is positioned at the distal portion of the elongated member for positioning distal of the blood clot, the sensor measuring a parameter of blood downstream of the clot. An indicator communicates with the sensor, the indicator indicating a measured parameter for insertion of an instrument for controlling blood flow.

A cannula system and method for accessing a blood mass in the brain. The system comprises a cannula with a camera mounted on the proximal end of the cannula with a view into the cannula lumen and the surgical field below the lumen. A prism, reflector or other suitable optical element is oriented between the camera and the lumen of the cannula to afford the camera a view into the cannula while minimizing obstruction of the lumen. The system may also include an obturator with a small diameter shaft and a large diameter tip which is optically transmissive, so that a surgeon inserting or manipulating the assembly can easily see that the obturator tip is near brain tissue (which is white) or blood (which is red).

A surgical instrument includes an end effector having a first jaw, a second jaw movable relative to the first jaw to grasp tissue therebetween, an anvil, a staple cartridge comprising staples deployable into the tissue, wherein the staples are deformable by the anvil, and a sensor configured to provide a sensor signal according to a physiological parameter of the tissue. The surgical instrument further includes a control circuit coupled to the sensor, wherein the control circuit is configured to receive the sensor signal, and assess proximity of the sensor to cancerous tissue based on the sensor signal.

Systems, methods, and devices having improved conformal properties for biomedical signal measurement are disclosed. A device can have a first polymer substrate coupled to a conductive layer forming a conductive trace electrically coupled to a conductive pad exposed via an opening. The device can have a second polymer substrate forming a first cavity between the first polymer substrate and the second polymer substrate. The device can have a first inlet portion that receives a fluid that expands the first cavity causing the device to conform to an anatomical structure. The structure can be an atrium, such as the left atrium, of the heart of a patient. The device can conform to the walls of the tissue structure, and the conductive pad exposed via the opening can detect a signal from the wall of the tissue structure. The signal can be provided to an external measurement device for processing.

Disclosed herein are medical device systems, and methods thereof, for automatically detecting access to a medullary cavity. Embodiments include intraosseous access systems with sensing obturators, configured to detect a change in modality, e.g. pressure, oxygen saturation, electrical impedance, etc. at a distal tip thereof. Signals can be transmitted to a control logic that can modify the activation of a driver in response. Signals can be transmitted by way of wired or wireless communication. In an embodiment, signals can be transmitted through conductive polymer material that forms the obturator and allows the obturator to be flexible enough to mitigate accidental needle stick injuries.
