Vascular treatment devices and methods include a woven structure including a plurality of bulbs that may be self-expanding, a hypotube, for example including interspersed patterns of longitudinally spaced rows of kerfs, and a bonding zone between the woven structure and the hypotube. The woven structure may include patterns of radiopaque filaments measurable under x-ray. Structures may be heat treated to include various shapes at different temperatures. The woven structure may be deployable to implant in a vessel. A catheter may include a hypotube including interspersed patterns of longitudinally spaced rows of kerfs and optionally a balloon. Laser cutting systems may include fluid flow systems.

An arthroscopic device is used with a hand piece having a motor drive with a rotating drive shaft. An elongate probe extending along a longitudinal axis and includes a proximal hub on a proximal end. The proximal hub detachably couples to the hand piece, and an operable-closeable jaw structure is disposed on a distal end of the elongate probe. A conversion mechanism carried by the hub converts a rotational motion of the motor drive shaft to a longitudinal motion of an actuator member. The actuator member drives the jaw structure between jaw-open and jaw-closed positions to resect bone and other hard tissues.

A treatment system can include a treatment tool including an ultrasound transducer and an end effector. The system can also include an ultrasound power source configured to output a drive signal to the ultrasound transducer, and a processor configured to detect an abnormality in the end effector, and whether end effector is immersed in a liquid. The system can continue an output of the drive signal from the ultrasound power source to the ultrasound transducer when the abnormality is detected and the end effector is immersed in the liquid.

In some examples, a catheter includes an expandable member configured to expand radially outward from a collapsed configuration to an expanded configuration. The expandable member is configured to be expanded and contracted in a controlled manner, e.g., in response to user actuation or automatically under the control of control circuitry of a device. For example, in some examples, control circuitry of a device can be configured to control the expandable member to expand and contract according to a predetermined expansion frequency or according to an expansion frequency determined based on a cardiac cycle of a patient.

Described here are methods and systems for the manipulation of ovarian tissues. The methods and systems may be used in the treatment of polycystic ovary syndrome (PCOS). The systems and methods may also be useful in the treatment of infertility associated with PCOS.

A motor-driven orthopedic impacting tool is provided for orthopedic impacting in the hips, knees, shoulders and the like. The tool is capable of holding a broach, chisel, or other end effector, which when gently tapped in a cavity with controlled percussive impacts, can expand the size or volume of an opening of the cavity or facilitate removal of the broach, implant, or other surgical implement from the opening. A stored-energy drive mechanism stores potential energy and then releases it to launch a launched mass or striker to communicate a striking force to an adapter in either a forward or reverse direction. The tool may further include a combination anvil and adapter and an energy adjustment mechanism to adjust the striking force the launched mass delivers to the adapter in accordance with a patient profile.

A surgical instrument includes a shaft, an ultrasonic transducer, a waveguide acoustically coupled with the ultrasonic transducer and extending distally through the shaft, and an end effector arranged at a distal end of the shaft. The end effector includes an ultrasonic blade acoustically coupled with the waveguide, a clamp arm movable relative to the ultrasonic blade for clamping tissue, and an RF electrode operable to seal tissue with RF energy. The ultrasonic transducer is operable to drive the waveguide and the ultrasonic blade with ultrasonic energy. The surgical instrument further includes an ultrasonic electrical circuit operable to energize the ultrasonic transducer, and an RF electrical circuit operable to deliver RF energy to the RF electrode. A return path of the ultrasonic electrical circuit and a return path of the RF electrical circuit pass through a shared electrically conductive element.

A surgical instrument for cutting and stapling patient tissue is disclosed. The surgical instrument comprises an end effector including a staple cartridge and staples, a firing element configured to move through the staple cartridge to cut the patient tissue and eject the staples from the staple cartridge during a staple firing stroke, an elongate shaft extending from the end effector, and a handle extending from the elongate shaft. The handle comprises a motor configured to output a rotary motion. The firing element is operably responsive to the rotary motion. The firing element is further configured to be driven at different speeds during the staple firing stroke. The handle further comprises a display. The display is configured to display the different speeds of the firing element during the staple firing stroke as a graphical representation.

A surgical instrument includes an end effector, a drive assembly operably coupled to the end effector, and a replaceable motor cartridge that includes a motor control circuit board and a motor. The surgical instrument further includes a main control circuit board including a processor and a computer-readable storage device storing program instructions, which when executed by the processor, cause the processor to detect a malfunction of the motor cartridge. The surgical instrument also includes an interface including a mechanical interface portion configured to releasably couple the motor to the drive assembly and an electrical interface portion configured to releasably couple the motor control circuit board to the main control circuit board.

A surgical instrument for stapling patient tissue is disclosed. The surgical instrument comprises an end effector, a firing element, an elongate shaft, a handle, an electric motor, and a display. The end effector extends from the elongate shaft and comprises a staple cartridge and a plurality of staples. The elongate shaft extends from the handle. The firing element is configured to move through the end effector between a proximal position and a distal position. The firing element is further configured to eject the plurality of staples from the staple cartridge during a firing stroke. The electric motor is configured to output a rotary motion and the firing element is operably responsive to the rotary motion. The display is configured to display a current position of the firing element during the firing stroke.
