An echogenic curette for carrying out a suction dilation and curettage allows the physician to view the curette and the pathology they want to remove, and use that to guide the procedure. The echogenic curette is visible using ultrasound imaging.

A vascular device is provided having a catheter body and a rotatable cutter assembly located at the distal end of the catheter body. The cutter assembly has at least one helical cutting surface within a housing that is coupled by a torque shaft to a drive mechanism. A conveyor mechanism helically wound about the torque shaft conveys occlusive material conveyed into the housing by the helical cutting blade further proximally along the catheter body for discharge without supplement of a vacuum pump. The catheter body is manipulated to insert the distal end of the catheter body within a body lumen and advance the distal end of the catheter body toward the occlusive material. The drive mechanism is operated to rotate the helical cutting surface to cut and convey the occlusive material from the body lumen proximally into the housing and to convey the occlusive material conveyed into the housing by the helical cutting surface further proximally along the catheter body by the conveyor mechanism for discharge without supplement of a vacuum pump. The distal end of the catheter body is deflected and rotated to sweep the cutter assembly in an arc about the center axis of the catheter body to cut occlusive material in a region larger than the outside diameter of the cutter assembly.

A medical device to effectively remove an object, like an intravascular thrombus, in a body lumen includes: a rotatable tubular driving shaft; a cutting part that is provided on a distal side of the driving shaft, rotates together with the driving shaft, and cuts the thrombus; and a second cutting part that is disposed near the distal side of the driving shaft, inward of the cutting part.

A dilator configured for separating subcutaneous fat from glandular tissue includes a center section, a first end section extending from a first end of the center section, the first end section extending nonparallel to the center section, the first end section having a first diameter, and a second end section extending from a second end of the center section opposite the first end, the second end section extending nonparallel to the center section, the second end section having a second diameter different than the first diameter. A retractor includes a handle, a shaft extending from the handle, and a head located at a shaft end opposite the handle. The head includes a plurality of teeth, each tooth having a tooth end curving downwardly from a head outer surface, adjacent teeth spaced from one another by a tooth gap therebetween, the plurality of teeth having unequal tooth lengths.

A surgical instrument for removing biological tissue during a surgical procedure comprises an elongate shaft and an end effector connected to the elongate shaft, the end effector including an edge configured to remove tissue, wherein curvature of one or both of the elongate shaft and end effector is adjustable to position the edge along a tissue surface when the curvature of the one or both of the elongate shaft and end effector is adjusted. A method of incising target tissue from an anatomic wall comprises inserting a shaft of a surgical instrument into an anatomic chamber of a patient, positioning a tissue-removal device connected to the shaft proximate the target tissue, deflecting an axis of the tissue-removal device relative to a central axis of the shaft, and shaving a surface of the anatomic wall by moving the tissue-removal device in a deflected state along the target tissue.

A synchronous drive system for simultaneously driving more than two or more rotational tissue screws and a method for simultaneously affixing a medical device to tissue employing the synchronous drive system. The synchronous drive system is particularly configured to affix an apical cuff to cardiac muscle tissue by simultaneously driving a plurality of rotational tissue screws through the apical cuff and into cardiac muscle tissue thereby affixing the apical cuff to the cardiac muscle tissue.

A handheld surgical device with a working portion driven by a motor, wherein the working portion is contained in a concave-shaped portion when it is not activated, and the working portion becomes exposed from the concave-shaped portion when it is activated. The activation of the working portion can be controlled by a switch located at a handle portion of the handheld surgical device. The handheld surgical device includes a concave-shaped portion with a cutting edge, which is not driven by the motor.

A direct-vision abortion uterine curettage device and a direct-vision abortion uterine curettage system are provided. The direct-vision abortion uterine curettage device includes a uterine curettage mechanism, an observation mechanism, a circuit, a negative pressure suction mechanism and an operating rod. A diagnostic curette of the uterine curettage mechanism is arranged at front ends of the operating rod and a camera and is in a visual field of the camera. The camera being mounted at the rear may guarantee that the diagnostic curette is completely within a range of the visual field of the camera, so that an operation procedure may be fully visible without any observation blind areas. Meanwhile, there will be no operation blind spots due to the diagnostic curette being blocked by a height of a lens module itself The direct-vision abortion uterine curettage system can perform surgical operations under real-time display of a display system.

A surgical instrument includes a first member defining an axis and having a scraping surface configured to scrape tissue. A second member includes a cutting surface that is rotatable relative to the first member. The second member has a maximum length defined by opposite end surfaces of the second member. The end surfaces are each disposed within the first member. A third member includes an outer surface defining at least a portion of a passageway configured for disposal of the scraped tissue. The third member is fixed with the first member. The cutting surface is rotatable relative to the third member to transfer the scraped tissue along the axis. Systems and methods are disclosed.

A medical instrument sheath including an elongated hollow tube having a wall comprised of polymeric material; and at least one electrical lead embedded inside the wall, wherein the at least one electrical lead is configured to be connected with a respective electrode disposed in a member located inside the sheath and extending from a distal end of the sheath.
