A delivery endcap assembly is adapted for use with a biliary access device and is adapted to permit a medical device to be delivered through the biliary access device. The delivery endcap assembly includes a securement portion adapted to be releasably securable to a proximal end of the handle after the one or more removable components have been removed from the handle, a tapered portion extending proximally from the securement portion, a rotation hub adapted to be coupled to the securement portion, a valve adapted to be coupled to the rotation hub and a lumen extending through the delivery endcap assembly, wherein the lumen extending through the delivery endcap assembly is adapted to permit a medical device within an introducer sheath to be advanced through the biliary access device.

The present invention provides a surgical training device for training laparoscopic first entry surgical techniques. The training device includes a simulated abdominal wall that is penetrable with an optical trocar. A receptacle containing a tissue simulation is located inside the receptacle. The tissue simulation is observable via scope placed inside the optical trocar. Upon penetration of the one or more of the simulated abdominal wall and receptacle, the tissue simulation appears to translate distally relative to the simulated abdominal wall. The distal translation is effected by a variety of ways including the release of negative pressure inside the receptacle upon penetration and the expansion of an elastic wall of the receptacle with the introduction of fluid under pressure into the receptacle.

A system can include an elongated instrument that is positioned within a cannula portion of a cannula assembly. The system can include a shield that is coupled with both the elongated instrument and the cannula assembly when in an unlocked state. The shield can permit proximal movement of the elongated instrument relative thereto when in the unlocked state. The shield can automatically transition to a locked state to attach to a distal end of the elongated instrument to restrict access to a distal tip of the elongated instrument.

A cannula mount for a surgical system includes a body configured to receive a portion of a cannula in a mounted state at the cannula mount; a pair of clamping components coupled to the body and configured to clamp the portion of the cannula in the mounted state of the cannula; and a latch assembly pivotably coupled to the body and slidably coupled to a clamping component of the pair of clamping components. At least one of the pair of clamping components is pivotable relative to the body to move the pair of clamping components between a first state to unclamp a cannula mounted at the cannula mount and a second state to clamp a cannula mounted at the cannula mount. Pivoting motion of the latch assembly relative to the body causes a portion of the latch assembly to slide along the clamping component and change a state of the pair of clamping components from an unlocked state to a locked state in the second state of the pair of clamping components.

The invention relates to a device in the form of a perforating trocar and is intended in particular to be used for surgery and interventional radiology. The device comprises an outer sleeve (5) having a rigid tube (8), and a mandrel (6) having a rod (18). The rod (18) is suitable for sliding in the outer sleeve (5) and has, at its distal end, a perforating tip (21, 33). The rod (18) additionally has a longitudinal groove (20) arranged on the surface of the rod (18), and extending from the distal end to the proximal end of the rod (18), in order to allow the device to slide on a guide pin.

According to one embodiment of the present disclosure, a surgical device is disclosed. The surgical device includes a motor and a transmission assembly movable by the motor. The surgical device also includes a force sensor configured to measure force imparted on the transmission assembly. The device may also include a controller configured to: control the motor to move the transmission assembly to a starting position, interrogate the force sensor to receive a sensor signal, compare the sensor signal to a threshold, and determine whether the force sensor is faulty based on the comparison of the sensor signal to the threshold.

Various surgical introducer needle and anchor systems are provided. The systems can include an introducer needle and a tissue support implant or sling device. The implant device can include one or more anchoring devices. The introducer needle device can include a handle assembly and a needle assembly. The needle assembly can include a generally hollow needle, and a wire traversable therein. The wire can include a distal tip adapted to selectively retract or withdraw from the engaged anchoring device upon deployment of the anchor and/or implant.

Adjacent tissue layers can be accessed using a catheter device with a distal tip having a conductive portion including a first cutting feature and one or more projections extending from the first cutting feature towards an outer diameter of the distal tip. Electrical energy can be supplied to the conductive portion of the device to cut tissue. A stent can be delivered to form a fluid communication between the adjacent tissue layers.

The present invention provides a surgical training device for training laparoscopic first entry surgical techniques. The training device includes a simulated abdominal wall that is penetrable with an optical trocar. A receptacle containing a tissue simulation is located inside the receptacle. The tissue simulation is observable via scope placed inside the optical trocar. Upon penetration of the one or more of the simulated abdominal wall and receptacle, the tissue simulation appears to translate distally relative to the simulated abdominal wall. The distal translation is effected by a variety of ways including the release of negative pressure inside the receptacle upon penetration and the expansion of an elastic wall of the receptacle with the introduction of fluid under pressure into the receptacle.

An optically transparent actuator apparatus is provided that includes an optically transparent bi-stable member including an optically transparent liquid crystalline polymer layer. The bi-stable member is structured to move from a first state to a second state in response to a first stimulus and from the second state to the first state in response to a second stimulus. Also, a display apparatus includes a plate member and an actuator assembly coupled to the plate member. The actuator assembly includes a number of optically transparent liquid crystalline polymer layers, wherein each of the optically transparent liquid crystalline polymer layers is structured to move from a first state to a second state in response to a first stimulus.
