Disclosed herein are apparatuses, systems, kits, and methods for treating skin, such as skin tightening or for treating diseases, disorders, and conditions that would benefit from tissue area or volume reduction, skin restoration, skin tightening, skin lifting, and/or skin repositioning and/or for generally improving skin function or appearance (e.g., the removal of unwanted skin features or irregularities such as sebaceous glands, sweat glands, hair follicles, necrosis, and fibrosis). Such apparatuses, systems, kits, and methods comprise an apparatus having a handheld main body and a detachably attachable tip comprising one or more needles.

Hollow vector support multifunctional protection devices and systems for minimally invasive surgery are disclosed. In an embodiment, a hollow vector support multifunctional protection device includes a protective head, a pitching mechanism for the protective head, an inner cylinder, an axial movement mechanism for the inner cylinder, and a shell. The protective head includes a flap ring, a plurality of first rotating shafts, a plurality of flaps uniformly arranged on the flap ring through the first rotating shafts, and a torsion spring arranged on the first rotating shafts. The torsion spring is configured to provide a force for opening the plurality of flaps along the first rotating shafts, and the first rotating shafts are provided with limiting structures configured to limit a maximum opening degree of the flaps.

Systems, apparatuses, and methods of and for an ophthalmic surgical system are disclosed. An ophthalmic surgical system may include a vitrectomy probe having a housing sized and shaped for grasping by a user. The vitrectomy probe may also include a cutter extending from the housing and being sized to penetrate and treat a patient eye. The cutter may include an outer cutting tube coupled to the housing. The outer cutting tube may have an outer port formed therein that is sized and shaped to receive tissue. The cutter may include a rotatable inner cutting member disposed within the outer cutting tube. The inner cutting member may include a first cutting surface that rotates across the outer port to cut the tissue when the inner cutting member is rotated. The vitrectomy probe may include a pneumatic vane actuator positioned within the housing and configured to rotate the inner cutting member.

In one exemplary aspect, the present disclosure is directed to a system. The system includes a pneumatic surgical instrument and a surgical console operable to provide compressed gas to the pneumatic surgical instrument. Additionally, the system includes a pneumatic drive line coupling the pneumatic surgical instrument to the surgical console. The pneumatic drive line has an internal bore configured to deliver the compressed gas to the pneumatic surgical instrument. The internal bore has a non-uniform cross-section along a length of the pneumatic drive line.

A surgical cutting and stapling end effector. Various embodiments comprise a channel that is configured to operably support a removable staple cartridge. A rotary end effector drive shaft is supported within the channel and is configured to move a firing assembly longitudinally within the end effector to cause the sled to eject surgical staples from the staple cartridge. The firing assembly is prevented from moving distally through the channel unless a surgical staple cartridge that has a sled in a starting position has been seated within the channel.

A medical device may include a shaft extending between a proximal end and a distal end. The shaft may include a lumen therein. The medical device may include a handle coupled to the proximal end of the shaft and may include a mode selector. The mode selector may be adapted to transition between a first mode and a second mode of the medical device. The medical device may further include a compressed fluid source. In the first mode, the compressed fluid source may be fluidly coupled with the shaft so as to impart a negative pressure in at least a portion of the lumen. In the second mode, the compressed fluid source may be fluidly coupled with the shaft so as to impart a positive pressure in the at least a portion of the lumen.

The tournicap is the only product of its kind that has the capability of simultaneously applying pressure to the bleeding site on the head, providing heat to the wound, and preventing third factor-acidosis that would otherwise be associated with hemorrhaging. This unprecedented product is uniquely designed with a tournicap made of a white impregnated kaolin gauze that works hand-in-hand with a boniquet made of plastic possessing inflatable air bladders for infection prevention. Moreover, the tournicap comes in multiple sizes to accommodate all patients and is incredibly easy to apply and secure onto the head to ensure immediate relief.

Disclosed herein are devices (e.g., needles (e.g., hollow needles), hollow staples, articles, apparatuses, and systems), kits, and methods for treating skin and skin conditions, for example, by promoting skin tightening, such as by reducing skin laxity and reducing tissue area or volume.

A parent artery occlusion (PAO) device which provides for immediate occlusion of a cerebral artery to isolate a defect. The PAO device includes a self-expanding wire-frame prolate structure which is partially covered with an ePTFE membrane.

A device for fracturing calcifications in heart valves including an expandable stabilizer and expandable impactor arms assembled on and deployed by a delivery system, wherein the delivery system is operable to move the impactor arms, while in an expanded position, with respect to the stabilizer with sufficient energy so as to fracture a calcification located in tissue which is sandwiched between the stabilizer and the impactor arms.
