Introduced here are novel techniques and tools for augmenting the lips through superficial linear injection of dermal fillers. At a high level, these techniques are representative of a two-step approach to augmentation. In the first stage, an implement that is appropriately positioned inside a lip can be moved sideways—an action referred to as a “side push.” In the second stage, dermal filler can be ejected from the implement so as to fill the resulting void. These techniques can be used by healthcare professionals to reshape the lips for medical or aesthetic purposes. These techniques were developed in an attempt to permit augmentation of the outer surface of a lip so as to increase its volume by expanding sideways while turning the lip outward. Presented here are also tools to improve the accuracy of injection. With these techniques, the desired result-namely, a plumper lip—may be readily and consistently achievable.

The present disclosure provides a method for reducing, removing, or dispersing a dermal filler aggregate in a subject. The method includes contacting a target area of the subject’s skin with a device configured to apply vibrational or mechanical energy, and applying vibrational energy to the target area for a duration sufficient to facilitate reduction, removal, or dispersion of the dermal filler aggregate. The vibrational energy may be applied while the device is held stationary over the aggregate or moved across the target area in vertical, horizontal, circular, or sweeping motions. In certain embodiments, the device is configured to contact the skin, and visible light is optionally applied during treatment. Application of vibrational energy promotes mechanical disruption and redistribution of dermal filler material within the surrounding tissue, thereby reducing the palpability or appearance of filler nodules, clumps, or irregularities.

The present invention relates to a dispersion comprising acellular dermal matrix microparticles, a filler comprising the same, and uses thereof. More specifically, the present invention relates to a filler comprising a dispersion containing acellular dermal matrix microparticles obtained by supercritical fluid extraction and high pressure dispersion operations, and a method for preparing the same. The acellular dermal filler according to the present invention has excellent biological stability and biocompatibility, and extracellular matrix components such as collagen and elastin are significantly preserved therein. In addition, the filling agent also shows excellent biochemical stability, the pH value or the collagen content and the elastin content are kept unchanged in the storage process, and the filling agent also shows physical stability and can continuously maintain injectability. Therefore, the acellular dermal filler can be effectively used as an injectable filler for repair or volume expansion of soft tissue and reduction of wrinkles in the field of plastic and regenerative medicine.

A method for filtering or removing agglomerates of individual particles from a viscous substance, such as a dermal filler formulation, is provided. The method involves loading the viscous substance into an extrusion system with a sieve or filter located inside, outside, or adjacent to the system, or external thereto. The substance is extruded through the filter / sieve, which filters / removes agglomerates present in the viscous substance due to their larger size. Alternatively, pressure-based filtration causes the separation of individual particles, which causes the agglomerates to break down, allowing the viscous substance to pass through the extrusion system without clogging issues. The filtered viscous substance is suitable for administration to a patient. The present invention also describes a device for implementing the proposed pressure-based filtration technique.

A method of filtering or removing agglomerations of individual particles from a viscous material such as a dermal filler formulation is provided. The method involves filling the viscous material in an extrusion system comprising a sieve or filter placed inside, outside, adjacent to or outside the system. The material is forced to pass through the filter / sieve which causes filtration / removal of the agglomerates present in the viscous material owing to its larger size. Alternatively, the pressure-based filtration cause separation of the individual particles causing breakdown of the agglomerates, thereby allowing the viscous material to pass through the extrusion system without any occlusion problems. The filtered viscous material is suitable for administration to the patients. The invention also describes devices to carry out the proposed pressure-filtration technique.

The current invention involves a method of mixing POP with a polysaccharide to obtain an improved injectable tissue matrix. POP is a partially ordered polypeptide and a polysaccharide, in this instance, comprises at least one glycosaminoglycan. The invention involves mixing these compounds in an injectable tissue matrix to increase volume retention, vascularization, and remodeling immune response, all of which are characteristics that would be useful for an injectable dermal filler, and in plastic and reconstructive procedures.

Syringe attachments and syringes have particular suitability to the precision dispensing of small amounts of high viscosity materials, such as dermal fillers. An attachment may include a main body having an assist feature that includes a wheel and pinion gears on each side of the wheel which engage respective racks on the syringe body. A mechanical advantage may be provided to the user as the wheel is rotated relative to the syringe body and racks. Syringes and attachments may include precision position indicators viewed from multiple positions to enable a user to determine plunger position and the amount of dispensed contents with precision. An alternative configuration attachment may be slidably secured to a syringe to permit a user to operation the syringe from a lateral position using sliding movement of the thumb and fingers of one hand, for example. This configuration may be particularly suitable for self-administered insulin injections.
