A surgical instrument for use with a robotic surgical system is described. The instrument includes an elongate shaft having a proximal end and a distal end. An electrically live wrist member is disposed at the distal end of the shaft. An electrocautery end effector is mounted to the wrist member. An interface is disposed at the proximal end of the shaft. The interface is removably connectable to the robotic surgical system. A conductor extends from the interface to the end effector so as to deliver electrical energy to tissue engaged by the end effector. A tip cover is disposed over the wrist member so that electrical current can only be conducted to tissues through the exposed end effector (e.g., to promote blood coagulation during usage) and not to other parts of the patient's body.

An elongate tubular body extends between a rotatable cutter and a control. The cutter is connected to the control with a rotatable element. A vacuum is applied through an annular passage defined between the tubular body and the rotatable element. The tubular body has a sufficiently small outside diameter and sufficient kink resistance and pushability to navigate through arteries such as the internal carotid artery.

A puncture device with a flexible catheter tube for connecting to a medical infusion line, wherein the device includes a catheter connecting piece or hub attachable at the puncture site on the skin surface of a patient, wherein the catheter hub has a connector for connecting the infusion line and an outlet for the flexible catheter tube; and a needle holder having a puncture needle (stylet), wherein the flexible catheter tube is arranged in the interior of the catheter hub and extends out of the outlet with an output end. The end of the flexible catheter tube opposing the output end is located in the interior of the catheter hub in the area of the connector and is separated from the surrounding area by a septum, wherein the needle holder securely fastens the puncture needle insertable into a passage channel of the catheter tube at the end opposing the pointed or sharp puncture tip. The outlet is located at the bottom side of the catheter hub resting on the surface of the patient in the position of use and the puncture needle is made without a duct.

In the case where the living tissues in the patient's body is resected as well, it is possible to suture the resected portion immediately without replacement with another treatment device after resection. Thus, prevention of bleeding from the resected portion or earlier repair of an ulcer that occurs with the resected portion can be carried out for the patent lowly invasively and easily.

The multi-cyclone dust separating apparatus includes a first cyclone unit having a body and including an air inlet disposed at a side of the body, a first cyclone chamber adapted to form a first space for whirling air from the air inlet to separate dust form the air; a second cyclone unit adapted to be detachably disposed at the body of the first cyclone unit and including, a second air inlet to draw the air from the first cyclone chamber, at least one cyclone for whirling the air from the first cyclone chamber to provide a second separation of dust from the air; and a dust bin adapted to be detachably mounted to at least one of the second cyclone unit and the first cyclone unit.

A system, apparatus and method for maximizing efficiency of tissue removal from body passageways is provided. The system comprises a device for opening an occluded lesion, e.g., a rotational atherectomy device or angioplasty device, and a guide wire having an introducer sheath. The guide wire introducer sheath may comprise a hypo tube having columnar strength greater than that of the guide wire alone to assist the guide wire in crossing occluded lesions, wherein the sheath and guide wire are axially moveable relative to each other. The guide wire sheath may further comprise increased flexibility at its distal end to increase flexibility and / or a soft distal tip to help with steerability through the vasculature. The sheath may allow for a smaller outer diameter guide wire which, in turn, may allow for a smaller outer diameter on the occlusion-opening device, e.g., atherectomy or angioplasty device, which is slid over the pre-positioned guide wire.

A device for protecting cerebral vessels or brain tissue during treatment of a carotid vessel includes a catheter having a distal portion, a proximal portion and a lumen extending therebetween, the catheter including first and second expandable areas for vessel occlusion provided over the length of the catheter. The device further includes an elongate stretching member insertable longitudinally through the lumen of the catheter, the elongate stretching member being configured for stretching at least a portion of the catheter and causing the first and second expandable areas to transition from an expanded state to a collapsed state, and wherein the elongate stretching member is retracted proximally relative to the catheter causes the first and second expandable areas to transition from the collapsed state to a radially, or laterally expanded state.

A factory-manufactured, preterminated fiber optic distribution cable having at least one predetermined access location for providing access to at least one preterminated optical fiber. A preterminated fiber optic distribution cable comprising at least one buffer tube comprising at least one optical fiber, a buffer tube transition piece operable for transitioning the at least one optical fiber from the at least one buffer tube into at least one protective tube, a C-shaped molded member defining a longitudinally extending optical fiber guide channel operable for storing a length of the at least one preterminated optical fiber and a protective means. A method of mid-span accessing at least one optical fiber from a fiber optic distribution cable. A buffer tube transition piece operable for transitioning a plurality of preterminated optical fibers from a buffer tube into protective tubing.
