A medical device is disclosed for collecting substances inside a body lumen. The medical device includes an elongated shaft portion; a filter portion that has multiple gaps, that is formed in a net shape, that is deformable to be in an expanded state where the filter portion has a basket shape so as to form a concave portion, and that is deformable from the expanded state to be in a contracted state where an opening end portion of the concave portion is contracted; and a support portion that is formed to include a gap larger than gaps of the filter portion and that includes an interlock portion interlocked with the opening end portion of the filter portion and a support side connection portion connected to the shaft portion.

According to some embodiments, a skin treatment assembly comprises a tip comprising a proximal end and a distal end, a container configured to secure to the tip along the proximal end of the tip, wherein the container is configured to contain a liquid, and a porous member configured to extend at least partially within an interior of the container such that it contact a liquid contained within the container, wherein the porous member is configured to extend at least partially within an interior of the tip and is configured to facilitate the transfer of liquid from the container to the distal end of the tip.

A debulking catheter includes an advancer for advancing a tissue-removing element, and a linear-force indicator. The linear-force indicator provides feedback to the user based on an amount of linear force being applied to the advancer.

Methods, devices and systems for separating an implanted object, such as a lead attached to a cardiac conduction device, from formed tissue within a blood vessel are provided. The methods, devices and systems for separating a lead from the tissue relate to dilating the tissue surrounding the lead from underneath the tissue and/or between the lead and the tissue.

A medical device and a treatment method are disclosed, which can improve safety by reducing damage to a biological tissue while an object inside a biological lumen can be cut. A medical device is disclosed for cutting an object inside a biological lumen includes a rotatable drive shaft, and a rotary structure that interlocks with a distal side of the drive shaft so as to be rotated by the drive shaft. The rotary structure has a cutting portion for cutting the object, and a non-cutting portion capable of smoothly coming into contact with a biological tissue. The non-cutting portion is located in a maximum outer diameter portion of the rotary structure.

A microdebrider comprising: (a) a handpiece; (b) an interchangeable tip connected to the handpiece; (c) an outer tune rotatably connected to the interchangeable tip, the outer tube including an outer tube window; (d) an inner tube extending at least partially through the outer tube, the inner tube including an inner tube window; (e) a lock selector connected to the inner tube; and (f) a bias device; wherein the bias device is movable, and upon movement of the bias device into contact with the lock selector the inner tube is immobilized so that the inner tube window is aligned with the outer tube window, aligned with a wall of the outer tube, or in a condition therebetween.

A wound care device for debriding a wound, said device is in the form of a foam pad with two layers of different foams. At one surface of the device is provided a pattern of grooved at the central portion. The grooves improve the ability of removing and collecting debris from a wound during cleaning of such.

An inexpensive yet effective implement for manual debridement comprises an elongated, integrally molded hand-held member having a proximal handle with a gripping portion, a distal head portion, and a flex portion between the handle and head portions. The head portion defines a bottom surface with a plurality of fluted structures, each fluted structure featuring a sharp edge. The handle portion is angled relative to the bottom surface of the head portion. The implement is packaged in sterilized form and intended to be disposed after use. In the preferred embodiment the fluted structures define partial, truncated cones, such that sharp edge is a curve or semi-circle. The gripping portion may also include a ruler or graduated markings. The flex portion may be ribbed or accordion-shaped to enhance flexing. The proximal-most portion of the handle includes a downward curve to maintain a user's grip.

The disclosure herein relates to methods for improving the appearance of skin, in particular facial skin. The method disclosed herein are designed to reduce the appearance of various skin conditions such as melasma, fine lines, and ruddiness due to natural aging and photoaging. More specifically, the present disclosure relates to a thee step process comprising light therapy, chemical peel, and dermaplane for improving the appearance of facial skin.

A tissue removal device and method of using the device to remove tissue from a patient is provided. The tissue removal device comprises a tissue removal probe and a sheath slideable relative to the probe. The probe has a tissue removal element, and the sheath has a portion that exposes the tissue removal element. The sheath distal end may be pre-shaped to bend when slid distal to the probe. The probe may have a window through which the tissue removal element is exposed.
