A laser surgery system (10) includes a source of laser energy (14), a controller (13) operatively coupled to the source of laser energy (14), and a laser surgical instrument. The laser surgical instrument comprises: a cladding (22,42) having a first refractive index; a fiber optic core (21,41) coaxially disposed within the cladding (22,42) and having a second refractive index that is higher than the first refractive in-dex, the fiber optic core (21,41) configured to be operatively engage with the source of laser energy (14) at a proximal end; a fiber optic tip (27,47) formed on a distal end of the fiber optic core (21,41) wherein the fiber optic tip (27,47) extends outwardly from the cladding (22,42); and a plurality of refracting surfaces (25,45) formed around the fiber optic tip (27,47), each refracting surface (25,45) formed at least at one angle relative to a longitudinal axis (A) of the fiber optic tip (27,47) and configured to disperse the laser energy in a radial pattern.

Intravascular implant systems and methods of positioning and detaching implants are described. One such system carries an implant by retaining an engagement member in a position proximal to an aperture at a distal end of the delivery system. The engagement member is retained proximal to the aperture by an elongate member that is coupled to the implant. Once the implant is in a desired implant position, the elongate member is released from the engagement member, and the implant is allowed to move away from the delivery system.

A station for cutting a barb suture is provided. The barb cutting station includes a suture transport assembly for supporting a first suture, a first knife assembly for forming barbs on the first suture, and a first clamp and position assembly for approximating the at least first suture towards the at least first knife assembly. The barb cutting station may further include at least a first suture cutting mechanism configured for severing the at least first suture when a defect is detected. The station may also include at least a first visual inspection assembly configured for detecting defective barbs.

A stapler is provided. The stapler includes a handle assembly and a shaft extending distally from the handle assembly. A tool assembly is configured to selectively couple to the shaft and includes a cartridge assembly and an anvil assembly. The cartridge assembly includes a staple guide defining a tissue contacting surface. A resilient member operably positioned within the cartridge assembly is configured to bias the staple guide distally to provide a predetermined compressive force against tissue when the cartridge assembly and anvil are approximated toward one another.

A dual-output generator is configured to output two or more waveforms at different frequencies. In particular, the dual-output generator is configured to provide low-frequency output, which may be suitable for ultrasonic surgical instruments, and a high-frequency output, which may be suitable for electrosurgical instruments, while reducing the amplitude of all remaining frequencies other than the two selected low and high frequencies to about zero.

A system includes a treatment probe, a first tracking sensor configured to track a location of the treatment probe, an ultrasound imager, a second tracking sensor configured to track a location of the ultrasound imager, and a tracking system. The ultrasound imager generates real-time ultrasound images. The tracking system receives location information from the first and second tracking sensors, tracks the location of the treatment probe and the location of the ultrasound imager, and displays the real-time ultrasound images and a representation of the treatment probe in one or more pre-stored images.
