A system includes, first and second circuitries and one or more devices. The first circuitry is configured to generate a stress signal for reducing an impedance of tissue of an organ. The second circuitry is configured to generate an irreversible electroporation (IRE) signal for producing a lesion in the tissue. The one or more devices are configured to apply to the tissue, the stress signal at a first time interval, and the IRE signal at a second time interval, subsequent to the first time interval.

A surgical system includes a robot main body, a slave controller, a display device that displays an endoscopic image, and an manipulation input device. The robot main body includes an entry guide having a plurality of guide bores, an entry guide support device that supports the entry guide, an instrument manipulator that has a surgical instrument provided at a distal end and is inserted into the entry guide, and an endoscope manipulator that has an endoscopic camera provided at a distal end and is inserted into the entry guide. The slave controller operates the robot main body such that the surgical instrument advances from an exit of the entry guide after the endoscopic camera advances from the exit of the entry guide and starts capturing in response to input of a body cavity insertion manipulation received by the manipulation input device.

A device for applying a hemostatic clip assembly includes a proximal delivery catheter having a handle assembly and an elongated catheter body defining a longitudinal axis extending distally from the handle assembly, and a distal clip assembly removably connected to a distal end of the catheter body. The distal clip assembly includes a distal clip housing, a jaw assembly and a jaw adapter yoke. The jaw assembly has a pair of jaw members fixed to the distal clip housing by a first pin oriented orthogonally relative to the longitudinal axis. The jaw adapter yoke is operatively connected to the jaw members. The proximal delivery catheter is configured to transmit linear motion along and torsion about the longitudinal axis to at least a portion of the distal clip assembly. At least one of the jaw members is configured to rotate about the first pin between an open and a closed configuration.

A proximal delivery catheter includes a proximal handle assembly, an elongated catheter body defining a longitudinal axis and extending distally from the proximal handle assembly, and a drive wire movably positioned within the elongated catheter body. A release pin assembly is coupled to a distal end of the drive wire. The release pin assembly including a release pin and a release pin housing positioned outward from the release pin. A shaft spring is positioned outward from the release pin housing. The shaft spring includes an annular portion wherein the release pin housing is configured and adapted to interfere with the annular portion of the shaft spring. A distal clip assembly is removably connected to the distal end of the elongated catheter body. The proximal delivery catheter is configured to transmit linear motion along and torsion about the longitudinal axis to at least a portion of the distal clip assembly.

A surgical instrument for treating tissue includes an articulating elongated shaft (14), a drive shaft (28) extending through the elongated shaft and configured to rotate about a longitudinal axis defined by the drive shaft, and an end effector assembly (100) coupled to a distal end portion of the elongated shaft. The end effector assembly includes a jaw member (110) and a blade member (112) configured to rotate in response to a rotation of the drive shaft to treat tissue disposed between the jaw member and the blade member.

An intracardiac echocardiography (“ICE”) catheter handle, including a housing having a longitudinal axis, the housing having a proximal end and a distal end. A first actuator can be positioned on a first portion of the housing in a plane aligned with the longitudinal axis, the first actuator coupled to a first controller, the first actuator and first controller configured to control a catheter coupled to the first controller in a first direction and a second direction in the first plane. A second actuator can be positioned on a second portion of the housing in a second plane aligned with the longitudinal axis, the second actuator coupled to a second controller, the second actuator and second controller configured to control a catheter coupled to the second controller in a third direction and a fourth direction in the second plane, wherein first plane is aligned orthogonally to the second plane.

The present disclosure is directed to end effectors. An end effector includes an outer shaft extending along a longitudinal axis and an inner shaft partially located within the outer shaft. The end effector may include an ultrasonic blade. The inner shaft may include biased and unbiased portions. The inner shaft and outer shaft may be translatable relative to one another. At one translatable position, the biased portion of the inner shaft may be located within the outer shaft and the unbiased portion may be substantially straight along the longitudinal axis. At another translatable position, the biased portion of the inner shaft may be located outside of and distally positioned from the outer shaft such that the biased portion of the inner shaft is bent away from the longitudinal axis.

A minimally invasive system comprises an elongate medical instrument including a flexible body. The flexible body includes a wall including a channel, and the channel includes a groove. The flexible body further includes a lumen defined by an interior surface of the wall and a curved distal tip portion. The elongate medical instrument further includes a shape sensor coupled to the flexible body. The shape sensor is at least partially positioned within the groove, and the shape sensor is configured to detect shape characteristics of at least a portion of the flexible body. The system further includes an actuator for manipulating the elongate medical instrument.
