There is disclosed a method of determining electrical properties in a peripheral nerve of a human or animal subject using a plurality of electrodes spaced around a perimeter of the nerve, by applying a probe electrical signal to each of a plurality of combinations of the electrodes, and using the resulting electrical responses to determine the electrical properties, for example by carrying out an electrical impedance tomography image reconstruction.

SURGICAL STAPLER
20210161531 · 2021-06-03 ·

The stapler of the invention is a surgical stapler/cutter that allows latero-lateral intestinal anastomosis, for both open surgery and laparoscopic surgery, at a distance from the openings used to insert the instrument. The stapler is based on the conventional structure of this type of stapler, and one of the fundamental features thereof is that an interspace (12) that determines a space for inserting the free ends (13, 13′) of the tissues (8, 8′) to be joined, is determined between an articulation shaft (3) of the two jaws (4, 5) of the stapler and the front end at which are disposed forms (6) and vertically movable teeth (9) on which staples (7) are disposed. This prevents the staples for the anastomosis and those for the removal of the pathological area from crossing when the area to be removed is cut. The invention also provides for the inclusion, in the described inter-space (12), of an Infrared Data Association (IrDA) device for testing blood flow that transmits a signal to a luminous signalling device which is visible to the user and which allows the degree of tissue vascularisation to be assessed.

A delivery system for an intracorporeal device includes a sheath defining one or more lumens shaped to receive a delivery catheter or shaft and a guidewire. The system may include a delivery shaft having a distal coupling feature adapted to releasably couple with a proximal coupling feature of the intracorporeal device. The delivery system may further include a hub through which the delivery shaft and guidewire are passed. The delivery shaft may be coupled to a feature, such as a knob, that enables manipulation of the delivery shaft to decouple the distal fixation feature from the proximal fixation feature of the intracorporeal device in order to deploy the intracorporeal device within a patient.
