Disclosed herein is a medical device. The medical device includes two coaxially aligned solenoids and a cannulated armature configured to be received within the two coaxially aligned solenoids.

Medical methods and devices for treating aortic dissections. A catheter-based cutting device permits cutting a septum of acute or chronic aortic dissections, in a retrograde manner. The catheter includes a base section having a central lumen therethrough and two flexible arms extending from a distal end thereof. The flexible arms can each have a guide wire channel therethrough. With distal ends of the two flexible arms separated, the two arms form a Y-shape with the base section. In one embodiment, with distal ends of the two flexible arms together, the two arms have a longitudinal profile, about a periphery thereof, identical to a longitudinal profile of the base section. A cutting component resides between the two arms. The cutting component can face distally outward between the two arms with the distal ends of the two flexible arms separated.

A vibrating tissue separator suitable for use in separating a lenticule established by a femtosecond laser during a smile procedure may include a surgical implement such as a blunt spatula mounted on a handle that carries a haptic actuator for applying vibratory motion to the surgical implement. A damping arrangement may be provided to isolate the surgeons hand from the vibrations which would otherwise be transmitted through the handle. The actuator may apply a linear vibration along the axis of the handle which applies a lifting and chopping motion to the tip of a surgical implement having a bend. The tip may be suitable to the tissue being separated. For example, for SMILE lenticule separation, a blunt or semi-sharp spatula, blunted wire or loop may be used. The direction of vibration at the tip may be changed by rotating the implement in a plane other than the plane of the bend or by rotating an actuator such as an LRA with respect to the handle.

An integrated hysteroscopic treatment system which includes an endoscopic viewing system, a fluid management system, a resecting device and a controller for operating all the systems.

Disclosed herein is a medical device. The medical device includes a blade tube section, a solenoid, and a mechanical arrangement. The blade tube section includes an outer blade tube, an inner blade tube, and a cutting window at a distal end of the blade tube section. The solenoid is offset from a central axis of the blade tube section. The mechanical arrangement is between the inner blade tube and the solenoid.

A medical device system configured to dynamically control a shaver window opening via controlling positioning of an opening in an inner drive shaft relative to an opening in an outer housing based on continuously tracking the motor is disclosed. The medical device system may include a shaver at a distal end and an aspiration system configured to aspirate material through the inner drive shaft. A processor of the medical device system may control rotational motion of the inner drive shaft based on continuously sensing the position of the opening in the inner drive shaft to reduce clogs and increase cutting effectiveness of the system. By continuously monitoring the medical device system, the processor can correct out of phase conditions in oscillation mode to prevent poor cutting conditions. The processor can also dynamically determine a reversal position on the opening in the inner drive shaft to create a desired cutting action.

Provided herein are vitrectomy instruments and related systems and methods in which the vitrectomy instruments may include a forward needle stop and a cutter stop to reduce dimensional variation of a cutter of the vitrectomy instruments, allowing for a location of the port formed in a needle of the cutter to be positioned closer to a distal tip of the cutter. With the port located closer to a distal end of the cutter, the port is able to be positioned closer to the retina of an eye.

Tissue may be cut and extracted from an interior location in a patient's body using a probe or tool which both effects cutting and causes vaporization of a liquid or other fluid to propel the cut tissue through an extraction lumen of the cutting device. The cutting may be achieved using an electrosurgical electrode assembly, including a first electrode on a cutting member and a second electrode within a cutting probe or tool.

Systems and methods involve abrading a patient lung airway wall to reduce mucus production therein. Exemplary techniques include rotationally and/or linearly oscillating an abrasive material against the airway wall so as to damage mucus producing tissues, for example by removing goblet cells, while destroying less than the entire airway wall. The abrasive material may be present on the surface of an expandable balloon body or another expandable device, which can be delivered to the patient treatment site via a bronchoscope. In some cases, the abrasion techniques can cause cell damage or death at a controlled or predetermined tissue depth.

Systems and methods for treating cellulite including an apparatus that applies or a method involving separating septa to eliminate or reduce the appearance of cellulite. In one approach, an interventional tool is placed between tissue layers to engage and treat septa connecting tissue layers between which fat deposits are contained.
