A vented microdermabrasion tip includes a disk-shaped abrasive component coated or configured with a microdermabrasive surface and fixed to a tubular sleeve by a set of annular mounts. The sleeve surrounds an outer periphery of the abrasive component, so that a gap is provided between the abrasive component and an internal air passage through the sleeve. A distal surface of the abrasive component is continuous, free of holes and coated with an abrasive material or formed with an abrasive surface. The distal surface extends beyond the distal end of the sleeve. An end of the mount opposite to the abrasive component is configured for coupling to a channel of a suction apparatus leading to an inlet of an air pump.

Reciprocating rasps for the surgical preparation of the bone prior to the implantation of a glenoid or acetabular component with complex geometry are disclosed. Surgical methods for the use of such reciprocating rasps are also disclosed.

A rotational atherectomy device advanceable over a guidewire. The rotational atherectomy device includes a drive shaft rotatably extending through an outer tubular member to rotate a cutting member positioned at a distal end thereof. The rotational atherectomy device further includes an insert positioned within the cutting member for frictional contact with the guidewire.

Various embodiments of devices and systems comprising a polymer driveshaft for use in high-speed rotational medical procedures, e.g., atherectomy, are disclosed. Generally, the primary driveshaft for transferring torque and activating rotation of a tool attached thereto, e.g., an abrasive element, is constructed with at least a polymer outer and inner surface. In certain embodiments, the polymer driveshaft may comprise a metallic band for fixed attachment of a structure, e.g., an abrasive element, thereto. Various embodiments may comprise a coupler that connects a drive shaft connected with a prime mover, e.g., a turbine or electric motor, with the polymer drive shaft, the coupler comprising openings through the coupler wall to the inner diameter of the coupler to allow fluid flow to the inner diameter of the coupled polymer drive shaft.

A rotational atherectomy device includes a drive shaft, a cutter mechanism coupled to the drive shaft and configured to cut occlusive material from a lesion, and a multi-stage macerator coupled to the drive shaft and configured to macerate cut occlusive material into a fine slurry. Successive stages of the multi-stage macerator macerate the cut occlusive material into successively smaller particles, which are moved proximally through a lumen of a sheath of the device that surrounds the drive shaft proximal to the macerator. The device may include a movable cutter mechanism guard that is passively rotatable between a first position in which it covers the cutter mechanism and a second position in which it exposes the cutter mechanism. One or more features of the device may limit a depth to which the cutter mechanism is able to cut the occlusive material to reduce a likelihood of undesirable tissue dissection.

A handle configured to be attached to a pumice stone. The handle includes a gripping portion and a post extending from the gripping portion. The post is configured to support the pumice stone. The post includes a support member, a series of ribs spaced apart along a length of the support member, and a series of cavities defined between adjacent ribs. The cavities are configured to accommodate an adhesive for coupling the post of the handle to the pumice stone.

A medical device and a treatment method are disclosed, which can effectively cut an object inside a biological lumen and can improve safety by reducing damage to a biological tissue. A medical device is disclosed for cutting the object inside the biological lumen. A structure rotated by a drive shaft has a first cutting portion, a second cutting portion located more proximal than the first cutting portion, a first non-cutting portion located between the first cutting portion and the second cutting portion, and a second non-cutting portion located on a proximal side of the second cutting portion.

The invention relates to a flexible application aid for the treatment of wounds. The application aid can be used in particular for the debridement and/or cleansing of wounds, including the skin surrounding the wound. The application aid according to the invention including a flexible or elastically deformable application wand, facilitates debridement of superficial to deep wounds without the risk of injury to the wound.

A callus removal apparatus includes a main body having opposite first and second end portions and an elongated configuration for ease of gripping by one hand, a callus scraping device fitted on the main body first end portion, and a callus sanding device fitted on and detachable from the main body second end portion. The callus scraping device has a head with an array of spaced-apart punched-through projections that extend upwardly from the head and have a plurality of jagged edges at a distal end thereof. The exposed projections are capable of removing pieces of a callus by moving the head across and in contact with the callus. The callus sanding device has a panel and a plurality of sanding particles attached on the panel and exposed at the exterior thereof and thus capable of removing pieces of a callus moving the panel across and in contact with the callus.

A system for removing matter from a partially or totally occluded stent includes a cutter that is urged radially outward toward the inner surface of the stent. Preferably, the cutter has a hardness that is less than or equal to the hardness of the material used to make the stent. Aspiration may be provided to remove portions of the occluding material from the vessel.
