Disclosed herein is a device for disrupting material in a body vessel and a method for making such a device. The device includes a plurality of arms disposed circumferentially about an axis. Each arm includes two blades; one sharper, and one blunter. The sharper blades are all oriented in the same direction, clockwise or counterclockwise, such that when the device is rotated in a first direction, the sharper blades engage the material, and in the other, the duller blades engage the material.

A vein harvesting device is disclosed. The vein harvesting device includes a handle assembly, at least one elongated portion, first and second end effectors, and a tip. Each end effector is disposed adjacent a distal portion of the at least one elongated portion. Each end effector includes a first jaw member and a second jaw member, and at least one jaw member is movable toward the other jaw member. The tip is disposed in mechanical cooperation with the elongated portion. A distal end of the tip extends distally beyond a distal-most end of the first end effector. The first end effector is movable independently of the tip, and the second end effector is movable independently of the tip.

Devices, systems and methods for treating diseases and disorders effecting the cardiovascular system of the human body are disclosed. An exemplary device in accordance with this disclosure comprises a shaft, tip member fixed to the shaft, and a probe extending beyond a distal surface of the tip member. In some useful embodiments, the tip member is relatively atraumatic and the probe is shaped so as to be more likely to produce trauma than the tip member.

Systems, instruments, and methods for minimally invasive procedures including one or more of fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision are described. Embodiments include instrumentation comprising a scalpet assembly coupled to a carrier, and the scalpet assembly includes a scalpet array. The scalpet array includes one or more scalpets configured for fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision. The system includes a vacuum component coupled to the scalpet assembly and configured to evacuate tissue from the a site. The carrier is configured to control application of a rotational force and/or a vacuum force to the scalpet assembly.

Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes inserting an intramural crossing device into the vascular lumen, positioning at least the distal tip of the crossing device in the vascular wall, advancing an orienting device over the crossing device such that an orienting element of the orienting device resides in the vascular wall, inserting a reentry device, and re-entering the true vascular lumen.

A medical device includes a shaft including a central lumen configured to direct a flow of fluid through the shaft, and an electrode positioned at a distal portion of the shaft. The electrode includes an electrode lumen in fluid communication with the central lumen, and the electrode lumen is configured to receive the flow of fluid from the central lumen. The electrode also includes one or more channels angled relative to the electrode lumen, and the one or more channels are in fluid communication with the electrode lumen to receive the flow of fluid from the electrode lumen. The one or more channels are configured to divert the flow of fluid from the electrode lumen toward one or more outlets laterally offset from the electrode lumen.

A surgical instrument comprising a jaw assembly is disclosed. The surgical instrument further comprises a motor-driven drive system configured to open the jaw assembly. The surgical instrument also comprises a control system configured to control the drive system and, also, control a power supply system configured to supply electrical power to electrodes defined in the outer surface, or outer surfaces, of the jaw assembly. In use, the surgical instrument can be used to apply mechanical energy and electrical energy to the tissue of a patient at the same time, or at different times. In certain embodiments, the user controls when the mechanical and electrical energies are applied. In some embodiments, the control system controls when the mechanical and electrical energies are applied.

Methods and systems for separating an object, such as a lead, from formed tissue are provided. Specifically, a tissue slitting device is configured to engage patient formed tissue at a slitting engagement point. While the object is subjected to a first traction force, the tissue slitting device is caused to move further into the engaged tissue and slit the tissue past the point of engagement. The slitting device causes the tissue to separate along an axial direction of the length of the formed tissue and releases at least some of the force containing the object. The methods and systems are well suited for use in cardiac pacing or defibrillator lead explant procedures.

An electrosurgical forceps includes first and second shaft members and first and second jaw members extending distally from the respective first and second shaft members. A pivot couples the first and second shaft members with one another such that the first and second shaft members are movable relative to one another between a spaced-apart position and an approximated position to move the first and second jaw members relative to one another between an open position and a closed position. The jaw members are configured to facilitate tissue treatment, tissue division, and blunt tissue dissection.
