Described here are systems and methods for delivering an active agent to target tissues of the ear, nose, or throat using an expandable member having drug crystals layered thereon, and methods for manufacturing such systems. The expandable member can be delivered to the target tissues in a low-profile configuration and expanded to contact and/or dilate surrounding tissue. Expansion of the expandable member transfers the drug crystals to the target tissues, which then act as an in situ depot that enables maintenance of a therapeutic level of an active agent for a desired time period after removal of the expandable member. Multiple expansions of a single expandable member can be employed during treatment. For example, the systems and methods can be useful when it is desired to treat multiple paranasal sinuses with a single expandable member.

In a method of creating a modified tissue graft, at least one exterior surface of a graft is modified by compressing, cutting and/or removing one or more portions thereof, such as to create designed surface features which cause the tissue graft to have characteristics for a specific anatomical area. The modified tissue graft may comprise a medicated graft, such as by associating medicants with the surface features, or by associating a second graft or layer with a modified base tissue graft layer, where medicants are associated with the second graft or layer. The tissue graft may be modified by pressing a specially configured template or die, such as having blades thereon, into the tissue graft, such as to create a pattern of partial depth cuts.

The present disclosure provides a coacervate composition containing a protein drug, gelatin A, sodium alginate and an acid and a wound-healing agent including the same. The coacervate composition according to the present disclosure can be useful as a wound-healing material delivery system for effectively delivering a protein drug, particularly epidermal growth factor, to a wound site in the wound-healing field.

This disclosure features elongated prosthetic devices that can be used to repair, e.g., resurface or occlude, a defect of a semicircular canal, e.g., a superior semicircular canal dehiscence, as well as methods of making and using these devices. For example, the devices can be made using three-dimensional (3D) printing.

A method of delivering a cell derived factors to a subject is described, which includes implanting a matrix material into an intracutaneous location in the subject that results in increased vascularisation and subsequently efficient delivery of the required cell derived factors to the subject. The implanted matrix material can be loaded in-situ or alternatively pre-loaded and inserted into the appropriate location depending on requirements.

The invention relates to an implant for subcutaneous implantation having a substantially cylindrical, conical or spiral-shaped base body which has a lateral surface. The base body consists of a completely resorbable biodegradable polymer. The implant is further configured for blunt implantation. In addition, the biodegradable polymer is enriched with a medicinally relevant active ingredient.

The present invention provides, in some aspects, bilayered and trilayered pharmaceutical implant compositions for the unidirectional delivery of anti-cancer compounds to the brain over a period of time (e.g., several weeks, 1, 2, 3, 4, 5, 6, 7 days, or 1, 2, 3, weeks, or any range derivable therein) following the removal of glioblastoma multiforme or other malignant tumors in the brain.

An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.

According to the present invention, there are provided a chamber for transplantation, including a membrane for immunoisolation at a boundary between an inside and an outside of the chamber for transplantation, in which the membrane for immunoisolation includes a porous membrane, and in the porous membrane, a maximum heat shrinkage ratio among heat shrinkage ratios in a membrane surface direction after immersion in water at 90 C. for 3 hours is 0.00% to 5.00%, and a difference between the maximum heat shrinkage ratio and a minimum heat shrinkage ratio among the heat shrinkage ratios in the membrane surface direction is 0.00% to 1.30%; and a device for transplantation including the chamber for transplantation enclosing a biological constituent therein. The chamber for transplantation of the present invention has a high durability and is capable of maintaining an enclosed biological constituent for a long period of time.
