A flexible portal cannula for use in arthroscopic surgery. Distally positioned flaps extend radially outwardly from the outer surface of the cannula and are resiliently foldable to lie against the outer surface of the cannula during insertion into a surgical portal, and resiliently biased to return to the radially outwardly extending position when unconstrained. A clip disposed on the cannula outer surface outside of an arthroscopic workspace acts to clamp tissue disposed between the clip and the flaps. The clip has an extension to receive pairs of slots to sort and engage the sutures.

A needle assembly (10) for relieving a pneumothorax and/or a hemothorax, the needle assembly (10) comprising a canula (12), the canula (12) comprising: a distal end portion (20) comprising a cutting end (22) for puncturing a thoracic cavity wall (24), a proximal end portion (14) for removing a fluid or gas from a thoracic cavity (28), a first curved portion (18) between the distal end portion (20) and the proximal end portion (14), an intermediate portion (16) between the first curved portion (18) and the proximal end portion (14), and a first fixing bulge (42) arranged between the first curved portion (18) and the intermediate portion (16), wherein an outer diameter of the canula (12) at the first fixing bulge (42) is increased with respect to the diameter (D1) of the intermediate portion (16), said first fixing bulge (42) being arranged such as to be placed at or close to the inner surface (24) of the thoracic cavity wall (24i), when the canula (12) is inserted for relieving the pneumothorax, such as to prevent or to reduce the risk that the canula (12) inadvertently slides out of its inserted position.

A deformable seal for use together with a laparoscopic port has a deformable body with an upper region, a lower region, and a narrowed waist. A plurality of tool passing channels are individually formed in an axial direction through the deformable body, and each tool passing channel has a tool entrance on a surface of the upper region and a tool exit on a surface of the lower region. The tool passing channels are sufficiently elastic to conform to and seal about a shaft of a laparoscopic tool present in the channel and to close to inhibit leakage of an insufflation gases when the tool is removed from the tool passing channel.

A surgical access device includes a cannula body, a fixation mechanism, and an illumination mechanism. The fixation mechanism includes a collar, a sleeve, an expandable member, and a distal ring. The illumination mechanism includes at least one light disposed on the expandable member, and a switch. Distal translation of the collar relative to an elongated portion of the cannula body causes the expandable member to move from a first position defining a first gap between a mid-portion of the expandable member and the elongated portion of the cannula body, to a second position defining a second gap between the mid-portion of the expandable member and the elongated portion of the cannula body, the second gap being greater than the first gap.

A surgical instrument access port assembly and method of use is disclosed. A locking mechanism includes a lock base having an aperture that receives the surgical access port. A locking member has an opening that receives the surgical access port. A ball having a lateral slit is received between the lock base and the locking member. The locking member is rotatable relative to the lock base into a locked position to secure the surgical access port with the ball when the surgical access port is inserted into fascia, and the locking member compresses the lateral slit in the locked position.

A support apparatus for supporting a trocar while the trocar extends through a body wall of a patient includes an inflatable collar and a slidable abutment collar commonly connected for engagement onto the trocar following which the slide collar is released to slide along the trocar. The inflatable collar is inflated to a set size by a manually operable pump on the slidable collar operated by squeezing finger abutments together up to a latch so that threaded portion expels the inflation fluid. The abutment member is shaped to be received on an outer surface of the trocar and adjustable longitudinally of the trocar sleeve so as to be located at a selected position by a manually movable latch collar. The inflatable collar and slidably collar are held connected by a manually operable release.

Systems and methods for processing sensor analyte data are disclosed, including initiating calibration, updating calibration, evaluating clinical acceptability of reference and sensor analyte data, and evaluating the quality of sensor calibration. The sensor can be calibrated using a calibration set of one or more matched sensor and reference analyte data pairs. Reference data resulting from benchtop testing an analyte sensor prior to its insertion can be used to provide initial calibration of the sensor data. Reference data from a short term continuous analyte sensor implanted in a user can be used to initially calibrate or update sensor data from a long term continuous analyte sensor.

A retention mechanism for a surgical access assembly is provided. The retention mechanism includes a planar base having first and second extensions each with a free end, a first locking member disposed on the free end of the first extension, and a second locking member disposed on the free end of the second extension. The first locking member includes a U-shaped body having a first set of opposed, inwardly facing teeth. The second locking member includes a U-shaped body having a first set of opposed, outwardly facing teeth configured engage the first set of opposed, inwardly facing teeth when the retention mechanism is in a locked condition. The first set of opposed, inwardly facing teeth and the first set of opposed, outwardly facing teeth are configured to be spaced apart from each other when the retention mechanism is in an unlocked condition.

A surgical access device includes a cannula, an instrument housing coupled to the cannula, a port coupled to the instrument housing, and a valve disposed within the port. The cannula includes an elongated shaft defining an access lumen and an inflation lumen therethrough. The port includes an inflation channel and an insufflation channel defined therethrough. The inflation channel is in fluid communication with the inflation lumen of the cannula and the insufflation channel is in fluid communication with the access lumen of the cannula. The valve is movable within the port between an inflation position in which a passageway defined through the valve is aligned with the inflation channel of the port, and an insufflation position in which the passageway of the valve is aligned with the insufflation channel of the port.

A trocar system includes a trocar assembly and a force sensor system. The trocar assembly includes a housing and an elongated cannula that extends from the housing. The force sensor system includes a force sensor supported on the trocar assembly, a control unit disposed in electrical communication with the force sensor, a processor, and a memory. The memory has instructions stored thereon, which when executed by the processor, cause the trocar system to sense, with the force sensor, a force applied through the trocar system, determine, with the control unit, if the force exceeds a predetermined threshold, and selectively output a signal through the control unit that indicates that the force exceeds the predetermined threshold.
