Abstract:
Methods for treating a vascular disease by delivering therapeutic compositions with enhanced endothelium targeting are disclosed. The compositions comprise bioactive agent nanoparticles encapsulated within polymeric microspheres or adhered to micrometer-sized particles.
Abstract:
A composition that includes nanoparticles with binding affinity for platelets, and methods for using this composition to treat vascular disease are disclosed.
Abstract:
Nano-constructs comprising nanoshells and methods of using the nano-constructs for treating or ameliorating a medical condition are provided.
Abstract:
An implantable medical device is disclosed having a helical construct including a set of spiral coils for local in vivo application of a therapeutic substance in a biological lumen. The helical construct is configured to apply less than 0.75 Bar of pressure to the biological lumen wall. The helical construct can have at least two sets of spiral coils having opposing helical directions. The device can be used for the treatment of vascular disorders such as restenosis and vulnerable plaque.
Abstract:
A catheter configured for delivering an agent to a patient's vessel wall, having self-expanding frame, and a method of delivering an agent to a patient's vessel wall. A first catheter has an elongated shaft with an agent delivery lumen and self-expanding frame on a distal shaft section formed of plurality of hollow tubes having joined first ends and free second ends, the free end of each hollow tube having an agent delivery port in fluid communication with the shaft agent delivery lumen and having a hooked tip configured for penetrating the vessel wall in the expanded configuration. Another catheter has a frame around the outer surface of a lining member such as a balloon or a tubular sleeve, such that the frame expanded against the vessel wall and the lining member together define a plurality of pockets between the vessel wall and the outer surface of the lining member.
Abstract:
Nano-constructs comprising nanoshells and methods of using the nano-constructs for treating or ameliorating a medical condition are provided.
Abstract:
Methods are disclosed for controlling the morphology and the release-rate of active agent from coating layers for medical devices comprising a polymer matrix and one or more active agents. The methods comprise fixing the morphology or phase distribution of the active agent prior to removing solvent from the coating composition. The coating layers can be used for controlled the delivery of an active agent or a combination of active agents.
Abstract:
Methods and compositions for the sustained release of treatment agents to treat an occluded blood vessel and affected tissue and/or organs are disclosed. Porous or non-porous bioabsorbable glass, metal or ceramic bead, rod or fiber particles can be loaded with a treatment agent, and optionally an image-enhancing agent, and coated with a sustained-release coating for delivery to an occluded blood vessel and affected tissue and/or organs by a delivery device.
Abstract:
The invention provides for a stent for implanting in a bodily lumen comprising a degradable structural element including: an abluminal layer comprising an active agent; and a luminal layer, wherein the abluminal layer has a faster degradation rate than the luminal layer.
