Various aspects of the present disclosure provide compositions including a water-insoluble therapeutic agent and a gallate-containing compound. Other aspects provide methods of using such compositions.

Coatings containing multiple drugs

A method for depositing a coating comprising a polymer and at least two pharmaceutical agents on a substrate, comprising the following steps: providing a stent framework; depositing on said stent framework a first layer comprising a first pharmaceutical agent; depositing a second layer comprising a second pharmaceutical agent; Wherein said first and second pharmaceutical agents are selected from two different classes of pharmaceutical agents.

Small vessel stent and methods of use

A drug delivery device having an intraluminal stent for improving coronary luminal diameter of small vessels in patients with symptomatic heart disease is disclosed. The intraluminal stent includes struts having a thickness of less than approximately 110 μm. A polymer is adhered to the intraluminal stent that includes from about 50 μg/cm.sup.2 to about 150 μg/cm.sup.2 of everolimus therein. Quantitative coronary angiography measurements indicate that the drug delivery device provides an in-stent late loss of less than about 0.20 mm and an in-stent diameter stenosis of less than about 15% at 12 months following implantation in a human.

Particle delivery via small-scale morphology materials for antibacterial applications

Disclosed herein is a particle delivery system comprising electrospun nanofiber comprised of coaxial fiber with a microfluidic core. Iron-doped apatite nanoparticles (IDANPs) have demonstrated a unique influence over phage killing of bacteria, whereby, IDANP-exposed bacterial cultures experience 2× the bacterial death as controls. IDANPs consist of hydroxyapatite (HA) doped with iron. HA is a mineral known to be biocompatible and analogous to the inorganic constituent of mammalian bone and teeth and has been approved by the Food and Drug Administration (FDA) for many applications in medicine and dentistry. Previous work has shown that for IDANPs to enhance antibacterial activity of phage to the greatest extent, bacterial cultures should be exposed to IDANPs for 1 hr prior to phage introduction. Biocompatible polymer materials which encase IDANPs and/or phage can be used to disseminate IDANPs and/or phage in a controlled manner into a physiological system for treatment of bacterial infection. When components of said materials contain micro- or nano-scale components, high surface-to-volume ratio for treatment delivery is garnered.

TISSUE THICKNESS COMPENSATOR COMPRISING AT LEAST ONE MEDICAMENT

In various embodiments, a tissue thickness compensator can comprise one or more capsules and/or pockets comprising at least one medicament therein. In at least one embodiment, staples can be fired through the tissue thickness compensator to rupture the capsules. In certain embodiments, a firing member, or knife, can be advanced through the tissue thickness compensator to rupture the capsules.
