Viruses around the uterine orifice and in the vagina are reliably and safely removed with a simple configuration. A virus removal device includes a drive source that generates power, a contact part that comes into contact with an affected part around the uterine orifice or in the vagina, a power transmission part that transmits the power generated by the drive source to the contact part, and an operation part that operates a position of the contact part, in which the contact part is operated by the operation part while being driven by the drive source, thereby scraping tissue of the affected part. The contact part scrapes the tissue of the affected part in squamo-columnar junction, which is a common site of cervical cancer, thereby physically removing the virus contained in the tissue of the affected part to prevent and treat cervical cancer.

A medical device that comprises a rim defining a loop in a plane and defining a width measured perpendicular to the plane, at least one wire coupled to a distal end of the rim and extending proximally from the distal end out of the plane to a proximal end of the rim, the at least one wire having a cross-sectional dimension measured perpendicular to a longitudinal axis of the at least one wire, the cross-sectional dimension being smaller than the width of the rim, and a sheath configured to cover at least a portion of the rim and a portion of the at least one ware.

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.

A surgical instrument is disclosed including a transducer configured to provide vibrations along a longitudinal axis, an end effector operably coupled to the transducer, and a stationary lower jaw extending parallel to the end effector. The end effector extends along the longitudinal axis. The end effector comprises a blade. The stationary lower jaw comprises a clamp face positioned distal to the blade. The end effector is movable relative to the stationary lower jaw to drive the blade distally towards the clamp face. The end effector comprises a hollow lumen. The end effector further comprises at least one member extended across a portion of the hollow lumen.

Methods and apparatuses for removing material (e.g., clot) from within a body, including inverting thrombectomy apparatuses. These methods and apparatuses may include methods and apparatuses for reusing portion of the devices, method and apparatuses for loading and reloading the inverting thrombectomy apparatuses, and methods and apparatuses for improving and enhancing the ability of the inverting thrombectomy apparatuses to remove clot. In particular, described herein are expandable scraper devices that may be used in conjunction with the inverting thrombectomy apparatuses descried herein, or on their own.

A minimally invasive tissue incision system for creating joint capsulotomies and releasing/incising various tissues, tendons, and fibrous band structures is described. The system contains a penetrating needle which is retractable so as to expose a cutting element, and which may be used as a penetrating needle to pierce the skin and other soft tissue structures. The cutting element provided within the penetrating needle may be used to incise subsequent tissue structures after the initial penetration. The system facilitates such procedures by providing the cutting element with the confines of the needle which provides safe introduction of the cutting element directly to the site via the needle.

Rotational atherectomy devices and systems can remove or reduce stenotic lesions in blood vessels by rotating an abrasive element within the vessel. The abrasive element can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly. In particular embodiments, the handle assembly includes a compressed gas driven turbine member that drives rotation of the drive shaft. The turbine member can be rotatably attached to a carriage that is longitudinally translatable in relation to a housing of the handle assembly. The handle assembly can include a latch mechanism that when actuated allows the carriage to translate to a proximal-most position. While the carriage is in the proximal-most position, an open pathway is created so that a guidewire can be slidably passed through the handle assembly and a lumen of the drive shaft.
