Abstract:
The present disclosed subject matter is directed to a less invasive surgical system, apparatus and method including a guidable catheter for providing electroporation therapy to a subject suffering from heart or kidney disease. The system includes an electrical generator and an apparatus for denervating an artery. The apparatus includes a catheter having a proximal end, a distal end, a first lumen with a first exit port, a second lumen having a second exit port. The apparatus also includes a first needle including a first electrode. The apparatus also includes a displacement mechanism engaged to the catheter near the proximal end such that the displacement mechanism controls the linear position and angular position of the catheter.
Abstract:
Compositions for forming a self-reinforcing composite biomatrix, methods of manufacture and use therefore are herein disclosed. Kits including delivery devices suitable for delivering the compositions are also disclosed. In some embodiments, the composition can include at least three components. In one embodiment, a first component can include a first functionalized polymer, a second component can include a second functionalized polymer and a third component can include silk protein or constituents thereof. In some embodiments, the composition can include at least one cell type and/or at least one growth factor. In some embodiments, the composition can include a biologic encapsulated, suspended, disposed within or loaded into a biodegradable carrier. In some embodiments, the composition(s) of the present invention can be delivered by a dual lumen injection device to a treatment area in situ, in vivo, as well as ex vivo applications.

Abstract:
An implantable medical device is disclosed having a plurality of smaller particles contained in a plurality of larger particles and configured to be released from the larger particles when the device is implanted in a patient. The smaller particles and the larger particles are made of bioabsorbable metal, glass or ceramic. A substance can be associated with the smaller particles. The larger particles can be embedded within at least a portion of the device.
Abstract:
A biocompatible plasticizer useful for forming a coating composition with a biocompatible polymer is provided. The coating composition may also include a biobeneficial polymer and/or a bioactive agent. The coating composition can form a coating on an implantable device. The implantable device can be used to treat or prevent a disorder such as atherosclerosis, thrombosis, restenosis, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, tumor obstruction, or combinations thereof.

Abstract:
A method including introducing a treatment agent at a treatment site within a mammalian host; and introducing a bioerodable gel material at the treatment site. An apparatus including a first annular member having a first lumen disposed about a length of the first annular member and a first entry port at a proximal end of the first annular member, and a second annular member coupled to the first annular member having a second lumen disposed about a length of the second annular member and a second entry port at a proximal end of the second annular member, wherein the first annular member and the second annular member are positioned to allow a combining of treatment agents introduced through each annular member at the treatment site.
Abstract:
An implantable medical device, such as a stent or graft, having asperities on a designated region of its outer surface is disclosed. The asperities can serve to improve retention of one or more layers of a coating on the device and to increase the amount of coating that can be carried by the device. The asperities can be formed by using a stream of pressurized grit to roughen the surface. The asperities can also be formed by removing material from the outer surface, for example, by chemical etching with or without a patterned mask. Alternatively, the asperities can be formed by adding material to the outer surface, for example, by welding powder particles to the outer surface or sputtering.
Abstract:
Polymers that can form the substrate of an implantable medical device and form coatings for implantable medical devices and methods for their fabrication are disclosed, the coatings comprising polymers that are hydrolyzed at a substantially constant rate or that have been prepared so that they degrade at a rate closer to constant.
