Wound cleaning device having a carrier layer and a wound cleaning layer arranged thereon, designed for holding wound exudate and/or solid wound components and having cleaning threads, the carrier layer and/or the wound cleaning layer being provided with at least one storage material that increases the capacity for holding wound exudate.

According to some embodiments, a method of treating a skin surface of a subject comprises heating a skin surface, abrading native skin tissue of a subject using a microdermabrasion device, wherein using the microdermabrasion device comprises moving the microdermabrasion device relative to the skin surface while simultaneously delivering at least one treatment fluid to the skin surface being treated and cooling the abraded skin surface.

A microstructured textile with microencapsulated compounds is used to enable a three part therapeutic delivery system. The microstructured textile can be turned into garments that passively deliver treatments to a user's skin. The microstructured textile has an a textile substrate, an abrasive material, and a microencapsulated compound. The textile substrate is an elastic material onto which the abrasive material is superimposed. The abrasive material removes dead skin when the microstructured textile is worn by the user. The microencapsulated compound is integrated into the textile substrate so that a therapeutic compound stored therein can be gradually released into the user's skin. Far infrared (FIR) emitting particles are integrated into the textile substrate. So, FIR radiation is applied to the user's skin to facilitate circulation.

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.

A medical device is disclosed for cutting an object in a body lumen. The medical device includes a rotation structure having a cutting portion and an outer surface of the cutting portion including a notch, and wherein a width of at least a proximal portion of the notch increases toward a proximal end of the notch; and a drive shaft connected to a motor and configured to be connected to the rotation structure to drive a rotation of the rotation structure.

Regions of tissue having reduced electrical propagation are created in a bladder to affect its electrical or mechanical properties. To create these tissue regions, a tubular device is advanced through the urethra leading to the interior of the bladder, a distal expandable structure of the device is expanded to contact the inner wall of the bladder, and electrodes or other active energy delivery elements of the device are activated to deliver ablation energy. The electrodes or other active energy delivery elements are disposed over the expandable structure which is shaped to conform to the interior of the bladder. The inner wall of the organ is ablated in a predetermined pattern. The same or other electrodes disposed over the expandable structure can used to electrically map the bladder. This map of electrical activity can be used to create the predetermined pattern.

The invention relates to a skin treatment device for removing callus from the skin by an abrasive treatment, comprising a housing with a handle section (110), a skin treatment element (120) rotatable around a rotational axis (101) and a protective rim (130). Said protective rim circumferentially encases said skin treatment element partially over an angular range of more than 120° and less than 330° about said rotational axis such that a circumferential abrasive treatment surface protrudes from the protective rim in an area extending over an angular range of 30° to 240°.

The invention is a device, system, and method for repairing heart valve function, which may include bisecting native valve leaflets for improved deployment of a prosthetic heart valve in the native valve annulus. The invention may include a catheter having a cutting element shaft with a cutting element configured to puncture a valve leaflet and/or make a controlled cut through the leaflet. The device may have an extendable foot configured to be positioned on an opposite side of the valve leaflet from the cutting element shaft. The device may include magnets to guide the cutting element and/or cutting element shaft in proper alignment with the extendable foot and to hold the elements in place during leaflet bisection.

A debrider that includes an outer member, an inner member located inside of the outer member, and an irrigation supply channel configured to supply irrigation fluid to a distal portion of an aspiration channel defined inside the inner member. The irrigation supply channel is located outside of the outer member.
