An insertion device for delivering media inside a patient includes an outer guide tube having a side port. An inner guide tube is nested within the outer guide tube and movable axially within the outer guide tube. The inner guide tube includes a deflector at an end within the outer guide tube. The device also includes a catheter nested within the inner guide tube and movable axially within the inner guide tube. The deflector of the inner guide tube is positionable such that it deflects the dispensing end of the catheter outward through the opening in the outer guide tube when the catheter is advanced axially within the inner guide tube. A therapeutic delivery cannula may be nested within the catheter, such that the deflected end of the catheter determines the direction of travel of the therapeutic delivery cannula into patient tissue when the cannula emerges from the catheter.

Aspects of the present disclosure include compositions having a plurality of individual polymeric nanowires. Individual polymeric nanowires according to embodiments include a bioactive compound. Methods for preparing and methods for administering the subject compositions of individual polymeric nanowires to a subject are also described. Kits having one or more components for practicing the subject methods are also provided.

Compositions of polymeric nanowires and methods of making and using thereof

Thin film devices, e.g., multilayer thin film devices, that encapsulate cells for transplantation into a subject are provided. Also provided are methods of using and methods of preparing the subject devices. The thin film devices include a first porous polymer layer and a second porous polymer layer that define a lumen therebetween and encapsulate a population of cells within the lumen. The thin film devices can promote vascularization into the lumen of the device via the pores in the first polymer layer and/or second polymer layer; limit foreign body response to the device; limit ingress of cells, immunoglobulins, and cytokines into the lumen via the first and the second polymer layers; and release from the first polymer layer and/or the second polymer layer molecules secreted by the population of cells.

Thin film cell encapsulation devices

Multilayer thin film devices that include a bioactive agent for elution to the surrounding tissue upon administration to a subject are provided. The multilayer thin film devices are useful as medical devices, such as ocular devices. Also provided are methods and kits for localized delivery of a bioactive agent to a tissue of a subject, and methods of preparing the subject devices. The multilayer thin film medical device includes a first layer, a bioactive agent and a second layer. The first and the second layers may be porous or non-porous. The devices have a furled structure, suitable for administration to a subject.

The present invention provides particulate contrast media for use in CT imaging. In an exemplary embodiment, the invention provides an enteric contrast medium formulation based on particles of low-Z elements selected from microparticles and nanoparticles. In various embodiments, the particles are coated with a material compatible with enteric administration of the formulation to a subject in need of such administration. The invention also provides methods for imaging of body parts simultaneously enhanced with contrast media of the invention and with other contrast media of a different type using CT imaging, including dual energy or spectral CT imaging. The invention also provides methods for the digital separation of CT signal produced by the contrast media of the invention from the CT signal produced by other contrast media or bodily tissues, to generate multiple resultant CT images with individual contrast materials subtracted or highlighted.

Microdevices containing a chamber bound on one side by a nanoporous membrane are provided. The nanoporous membrane may contain hollow nanotubes that extend through the nanoporous membrane, from one surface to the other, and extend beyond the surface of the nanoporous membrane opposite the surface interfacing with the chamber. The nanotubes may provide a fluidic conduit between an environment external to the microdevice and the chamber, which is otherwise substantially fluid-tight. Also provided are methods of making a microdevice and methods of using the microdevices.

Nanostraw devices and methods of fabricating and using the same

Compositions including a surface or film comprising nanofibers, nanotubes or microwells comprising a bioactive agent for elution to the surrounding tissue upon placement of the composition in a subject are disclosed. The compositions are useful in medical implants and methods of treating a patient in need of an implant, including orthopedic implants, dental implants, cardiovascular implants, neurological implants, neurovascular implants, gastrointestinal implants, muscular implants, and ocular implants.

Methods of modulating healing response to vascular injury and/or vascular scarring in a subject are provided. As such, aspects of the disclosure relate to the use of pro-resolving lipid mediators to modulate inflammation and/or restenosis of a vascular wall. Another aspect of the disclosure relates to the use of pro-resolving lipid mediators to modulate a biological activity of vascular smooth muscle cells (VSMC) or vascular endothelial cells (VEC). Pro-resolving lipid mediators that fmd use in the subject methods include derivatives of omega-3 polyunsaturated fatty acids and omega-6 polyunsaturated fatty acids, such as resolvins, protectins, lipoxins and maresins and their therapeutically stable analogs. Also provided are vascular devices and compositions for use in the subject methods. Such methods, devices and compositions fmd use in a variety of applications, including applications related to treatment of vascular injuries and vascular scarring (e.g., restenosis), and applications related to chronic inflammatory diseases of the vascular wall.
