  • Patent number: 11963942
    Abstract: A pharmaceutical composition comprises a taxane (e.g., paclitaxel, docetaxel, cabazitaxel, larotaxel, ortataxel, and/or tesetaxel) in a mixture of first and second surfactants. The absorption of the taxane is increased from the pharmaceutical composition is greater than the sum of the absorption of docetaxel from either the first or the second surfactant. The increase in absorption is especially enhanced when the ratio of the first surfactant to the second surfactant in the pharmaceutical composition is between 60:40 and 85:15 by weight, and the total surfactant weight does not exceed 98% of the total weight. Polysorbate 80, polysorbate 20, and caprylocaproyl polyoxylglycerides serve as suitable first surfactants, and polysorbate 80 or polyethyoxylated castor oil serve as suitable second surfactants. The stability of the pharmaceutical composition may be enhanced by further including a stabilizer (e.g., citric acid and/or ascorbic acid).

  • Patent number: 11944717
    Abstract: Disclosed are methods, devices and materials for the in situ formation of a nerve cap and/or a nerve wrap to inhibit neuroma formation following planned or traumatic nerve injury. The method includes the steps of identifying a severed end of a nerve, and positioning the severed end into a cavity defined by a form. A transformable media is introduced into the form cavity to surround the severed end. The media is permitted to undergo a transformation from a first, relatively flowable state to a second, relatively non flowable state to form a protective barrier surrounding the severed end. The media may be a hydrogel, and the transformation may produce a synthetic crosslinked hydrogel protective barrier. The media may include at least one anti-regeneration agent to inhibit nerve regrowth.

  • Patent number: 11819591
    Abstract: An iron-based alloy absorbable and implantable medical device for internal fixation. A substrate includes an iron-based alloy and degradable polymer. The mass ratio of the iron-based alloy to the degradable polymer is between 1:4 and 4:1. The weight-average molecular weight of the degradable polymer is between 150000 to 3000000, and the polydispersity index thereof is between 1 and 6. The device further includes antioxidants. The iron-based alloy is used as a load-bearing framework or reinforcement phase of the device. By adjusting the mass ratio of the iron-based alloy to the degradable polymer and the combination mode thereof, the corrosion rate of the iron-based alloy in the late period of the implantation is accelerated, and the quantity of corrosion products poorly soluble in the iron-based alloy is reduced. Adding antioxidants to the device further reduces the quantity of the corrosion products poorly soluble in the iron-based alloy.

  • Patent number: 11771805
    Abstract: An injectable in situ pore-forming hydrogel system and its preparation method and use are provided. The injectable in situ pore-forming hydrogel system uses an injectable hydrogel as a continuous base phase, and isolated live cells and magnesium particles are distributed in the continuous base phase, where the injectable hydrogel is a precursor or prepolymer of hydrogel, which can form hydrogel by cross-linking. The injectable in situ pore-forming hydrogel system can be used to create pores while the gel encapsulates live cells, which makes use of both the injectability and porous structures of hydrogel, which is important for the repair of cavitary, surgically difficult and irregularly defective tissues; meanwhile, magnesium particles generate magnesium ions after the former undergoes gas production and degradation, which can improve the bioactivity of the gel and aid in tissue repair.

  • Patent number: 11612754
    Abstract: Nonwoven resorbable pouches that at least partially enclose implantable medical devices and improved methods for producing the implantable medical device pouches are described. The nonwoven pouches may comprise one or more drugs. Implantable medical devices that are placed in the pouches prior to implantation are prevented from migrating from the site of implantation by tissue ingrowth into the pouch. Antibiotics may be incorporated into the pouches to prevent post-operative infections. The pouches may be formed in fewer steps than conventional pouches, and without polymer coatings. Nonwoven pouches can be formed in one step by dry spinning instead of using multiple processing steps. In embodiments, the nonwoven pouches are smoother on the inside than the outside to tightly fit the implantable medical devices internally while encouraging external tissue ingrowth.
