Abstract: A surgical access device, such as in the form of a Veress needle or trocar/obturator, for use in providing access to a patient in a surgical setting is disclosed. The surgical access device incorporates one or more sensors to provide real-time data usable to evaluate an insertion position of the surgical access device and provide feedback to a live user or robotic insertion device. Additionally, a system and method for adjusting a flow of insufflation gas based on the real-time data and a sensed pressure at the surgical access device is described.

Abstract: A smoke evacuation flow regulator for use with a suction source to rapidly remove excess smoke during an endoscopic surgical procedure is described. The smoke evacuation regulator may include a body having a gas pathway and a knob assembly threadably attached to the body that is sized to completely open or completely close the gas pathway in a single revolution of the knob assembly. The head of the knob assembly may be sized and shaped to permit tactile determination of the rotational position of the knob assembly in low vision situations. The body of the smoke evacuation flow regulator may include a knob assembly retaining arm that cooperates with a disk or extension on the knob assembly to allow rotational freedom of the knob assembly, but prevent inadvertent removal of the knob assembly from the body during use.

Abstract: Electrohydraulic lithotripters comprising a plurality of electrohydraulic probes are disclosed. Each probe of the plurality of probes comprise a first electrode and a second electrode positioned at a distal end of the probe such that when the probe is discharged, an electric arc between the first electrode and the second electrode produces a shockwave that radiates from the distal end of the probe. A first probe and a second probe of the plurality of probes may be configured to discharge simultaneously or sequentially.

Abstract: A surgical access device, such as a trocar, for use in providing access to a patient in a surgical setting is disclosed. The surgical access device includes an irradiation component to inactivate and sterilize gas that accidentally escapes a pneumoperitoneum, or ambient gas from outside the patient that may become entrained into the pneumoperitoneum. The surgical access device may include a central lumen that is gasketless or implements a gasket. The irradiation source may include an ultraviolet radiation source on or in the body of the surgical access device, and may be part of a discrete, removable attachment to a main part of the surgical access device body.

Abstract: A recessed D-subminiature connector assembly, and device with D-subminiature connector assembly, with flush mount cover connector is disclosed. The D-subminiature connector assembly may include a flush panel mount solution when using a D-Sub connector that allows the dust cover or cap to be in the same plane as the external side of the panel it is mounted to. The D-subminiature connector assembly also includes a panel-side interface flange sized to receive the second side of the D-shaped connector so a surface of the second side of the D-Shaped connector is parallel to, and recessed from, a plane of the panel-side interface flange and thus recessed from an opening of a panel of a device to which the connector assembly is mounted.

Abstract: A lithotripter tip configured for use within an invasive lithotripter probe may include a lithotripter tip body defining an interior region in communication with an aperture at a distal end of the lithotripter tip body and defining at least one port in communication with the interior region. A first electrode and a second electrode are positioned within the interior region of the lithotripter tip such that such that when liquid is within the interior region and an electric arc occurs between the first and second electrodes, a gaseous bubble forms within the interior region and a resulting shockwave travels out of the aperture at the distal end of the lithotripter tip body.

Abstract: A gas apparatus for use in a medical procedure may include a housing, a heater, a port, and a dispensing device. The housing defines a chamber having a gas inlet and a gas outlet. The heater warms a gas flowing through the chamber. The port is positioned in fluid communication with the chamber. The dispensing device is inserted within the port for delivering water in aerosol form to warmed gas as it exits the gas outlet.

Abstract: An in-dwelling port for providing repeated entry to a body during and/or after an operation is described. The port may include an external portion secured to a body outside an incision and a collapsible insertion portion that is inserted through the incision. The collapsible portion collapses when no instrument or lumen is present to permits the body to return to substantially a normal profile around the incision.

Abstract: An insufflation system is provided that includes an insufflator having a delivery assembly for delivering insufflating gas from a pressurized source of insufflation gas to at least one gas delivery path. At least one output line is coupled to the at least one gas delivery path. At least one dual-capacity tube has a first tube with a first end coupled to the at least one output line and a second end. The dual-capacity tube has a pair of tubes that each has a first end attached with the second end of the first tube. The dual-capacity tube provides for fluid communication of the insufflating gas between the insufflator and laparoscopic equipment that is insertable into a peritoneal cavity.

Abstract: A method of humidifying a gas that includes supplying a gas to a surface of a humidification material that readily absorbs moisture and readily releases moisture when exposed to a dry environment and generating turbulence in the gas as it passes over the surface of the humidification material.
