Compositions including a first soft tissue-derived matrix and a second soft tissue-derived matrix are provided, as well as methods of making such compositions. In some embodiments, the composition comprises delipidated, decellularized adipose tissue-derived matrix and delipidated, decellularized fascial tissue-derived matrix, which may be combined in various proportions. Such adipose-fascia matrix compositions provide improved volume retention when implanted into a patient. The composition may further include exogenous cells or other substances, and/or a carrier. The composition is suitable for use in plastic surgery procedures, including reconstructive or cosmetic surgery procedures, as well as procedures for wound treatment and tissue regeneration. The methods for making the compositions may involve separation of first and second soft tissues from one another, followed by performing one or more treatments on the separated soft tissues, then combining the treated soft tissues and, optionally, performing one or more additional treatments on the combined soft tissues.

Disclosed are injectable dermo-aesthetic formulations comprising aqueous solutions of at least one unmodified high-molecular-weight linear hyaluronic acid or hyaluronate and at least one unmodified low-molecular-weight linear hyaluronic acid or hyaluronate or non-sulphated chondroitin. The compositions according to the invention are useful as fillers with an excellent safety profile, adequate residence time at the site of application, and limited extrusion force.

Methods and devices that accelerate and improve graft induced growth of host living cells by application of mechanical tension over the graft/host construct that invites host cells to grow, multiply, and repopulate the graft matrix.

Disclosed herein are soft tissue fillers, for example, dermal and subdermal fillers, based on hyaluronic acids and pharmaceutically acceptable salts thereof. Some of the hyaluronic acid-based compositions can include a therapeutically effective amount of at least one anesthetic agent, for example, lidocaine. Compared to conventional compositions that include lidocaine, some of the hyaluronic acid-based compositions disclosed herein can have an enhanced stability, for example, when subjected to sterilization techniques or when stored for long periods of time. Methods and processes of preparing such compositions are also provided.

The present disclosure provides meshed acellular dermal tissue matrix compositions, devices, and methods of use. The meshed devices can be used in conjunction with a variety of implants such as breast implants or tissue expanders.

The present disclosure relates to a hybrid material, such as a hybrid yarn, as well as methods of making and using the same. The hybrid material may include tropoelastin. Further, the hybrid material can also include a biodegradable polymer. In addition, the disclosure is also directed to compositions and methods for treating a tissue, such as treatment of organ prolapse.

The invention provides a synthetic gingival patch graft having a porous polymeric structure and uses thereof in the C method of treatment of periodontal diseases, conditions and symptoms.

Various aspects described herein relate to compositions comprising silk fibroin particles and methods of using the same, as well as devices and methods of delivering such compositions. The compositions described herein are suitable for injection into a site of defect in a soft tissue to provide bulking and/or augmentation effect to the soft tissue.

The present invention provides novel methods for poling piezoelectric materials, e.g., collagen, which are carried out in the absence of liquid media and at a relatively low temperature. The present invention also provides electroactive scaffolds comprising poled collagen for promoting cell growth and differentiation.

Various aspects described herein relate to compositions comprising silk fibroin particles and methods of using the same, as well as devices and methods of delivering such compositions.
