The device may include another electrode, a controller in communication with the first electrode via a first lead and in communication with the second electrode via a second lead, where the first lead runs through an inner lumen of the cannula and where the device is configured to detect an impedance or a conductance of the tissue between the first electrode and the second electrode, and where the controller is configured to receive one or more signals from the tissue adjacent to the distal end of the cannula and detect a change in property of the tissue as the cannula is advanced, and where the controller is further configured to determine a position of the distal end of the cannula during advancement into the body. | 2019-01-03 |
20190000502 | TROCAR OBTURATOR WITH DETACHABLE ROTARY TISSUE FASTENER - A surgical instrument includes a shaft and a tissue fastener. The tissue fastener is releasably attached to the distal end portion of the shaft. The shaft is operable to rotatably drive the tissue fastener about a longitudinal axis of the shaft. The tissue fastener includes a base, first and second arms, and barbs. The first and second arms extend laterally and longitudinally from the base and are configured to be received within a first and second tissue portion, respectively. The first and second arms are configured to draw the first tissue portion against the second tissue portion. The barbs extend from the first and second arms and are configured to anchor the first and second arms within the first and second tissue portions. The shaft is configured to release the tissue fastener thereby securing the first tissue portion against the second tissue portion with the tissue fastener anchored therein. | 2019-01-03 |
20190000503 | TROCAR WITH OBLIQUE NEEDLE INSERTION PORT AND COPLANAR STOPCOCK - A surgical access device includes a cannula and a housing assembly coupled to a proximal end of the cannula. A working channel defined by a cannula lumen and a housing interior extends between proximal and distal ends of the surgical access device along a central axis thereof. The working channel is configured to receive a surgical instrument, and an insufflation port is configured to direct insufflation fluid into the working channel. First and second needle ports open to the working channel through respective first and second side portions of the surgical access device. The first needle port is diametrically opposed from the insufflation port. Each of the first and second needle ports is configured to direct a suture passer needle through the surgical access device, across the working channel, at an oblique angle relative to the central axis. | 2019-01-03 |
