Methods and devices for utilizing bondable materials
The invention primarily relates to fastening and stabilizing tissues, implants, and/or bondable materials, such as the fastening of a tissue and/or implant to a bondable material, the fastening of an implant to tissue, and/or the fastening of an implant to another implant. This may involve using an energy source to bond and/or mechanically to stabilize a tissue, an implant, a bondable material, and/or other biocompatible material. The invention may also relate to the use of an energy source to remove and/or install an implant and/or bondable material or to facilitate solidification and/or polymerization of bondable material.

CATIONIC STEROIDAL ANTIMICROBIAL COMPOSITIONS FOR THE TREATMENT OF DERMAL TISSUE
This disclosure relates to dermal treatment compositions, such as dermal fillers and tissue glues, and injectable compositions that incorporate one or more cationic steroidal antimicrobials (CSAs). The CSAs are incorporated into the dermal treatment compositions to provide effective antimicrobial, anti-inflammatory, analgesic, anti-swelling and/or tissue-healing properties. A treatment composition includes a component formed from a biologically compatible material suitable for injection into and/or application onto tissue at a treatment site. One or more CSA compounds are mixed with the biologically compatible material so that the one or more CSA compounds are incorporated within the composition, forming a reservoir of CSA compounds within the resulting bolus of the treatment composition after injection and/or application.
Cement products and methods of making and using the same
Disclosed are cement products, methods of forming cement using the cement product, and methods of using the cement product in orthopedic and dental applications. Generally, the disclosed cement product includes a first component and a second component. The first component comprises a polymerizable resin comprising ethylenic unsaturated double bond, a suitable glycidyl group and/or a suitable isocyanate group. The second component includes a compound comprising more than one type of amine selected from the group consisting of primary amine, secondary amines, tertiary amines and quaternary amines. Alternatively, the second component includes a compound comprising a suitable mercapto (SH—) group, a hindered amine or a dimethylthiotoluenediamine (DMTDA). Optionally, the cement product includes a filler and/or a bioactive component to promote bone formation.

SEALING AGENT FOR GENITALS
The present invention aims to provide a cervical canal sealant that can be used as a sealant to stop bleeding in the uterus and vaginal discharge, particularly, a cervical canal sealant that can block the cervical canal to inhibit amniotic fluid leakage and that can also be peeled off without damaging reproductive tissue. The present invention relates to a sealant for reproductive organs in which a cured product (X) at 25° C. has a storage modulus G′ of 200 to 2,000 kPa, the cured product (X) being a cured product obtained by curing the sealant for reproductive organs to a thickness of 120 to 150 μm.

ELASTOMERIC COMPOSITIONS AND THEIR APPLICATIONS
A condensation curable gel composition is disclosed. The composition comprises: (i) at least one condensation curable silyl terminated polymer having at least one hydrolysable and/or hydroxyl functional group(s) per molecule; (ii) a cross-linker selected from the group of a silicone, an organic polymer, a monosilane or a disilane molecule which contains at least two hydrolysable groups per molecule; and (iii) a condensation catalyst selected from the group of titanates, zirconates or tin (II). The molar ratio of hydroxyl and/or hydrolysable groups in polymer (i) to hydrolysable groups from component (ii) is between 0.5:1 and 1:1 using a monosilane cross-linker or 0.75:1 to 3:1 using disilanes. The titanates and zirconates comprise M-OR functions where M is titanium or zirconium and R is an aliphatic hydrocarbon group. The molar ratio of M-OR or tin (II) functions to the hydroxyl and/or hydrolysable groups in polymer (i) is comprised between 0.01:1 and 0.5:1.
Biomedical Foams
The invention relates, generally, to porous absorbent materials which are suitable for packing antrums or other cavities of the human or animal body. More particularly, it relates to hydrophilic biodegradable foams, which may be used e.g. in the form of a plug or tampon, for instance for controlling bleeding, wound closure, prevent tissue adhesion and/or support tissue regeneration. The invention provides an absorbent foam, suitable for packing antrums or other cavities of the human or animal body, comprising a biodegradable synthetic polymer, which polymer preferably comprises —C(O)—O—groups in the backbone of the polymer, for instance polyurethane and/or polyester units combined with polyethers.
