Abstract:
Polymers containing poly(hydroxyalkanoate-co-ester amides) and agents for use with medical articles are disclosed along with methods of fabricating medical articles comprising these polymers. The medical articles generally comprise an implantable substrate having a coating containing a poly(hydroxyalkanoate-co-ester amide).
Abstract:
An apparatus and method to treat vulnerable plaque. In one embodiment, the apparatus has an elongated catheter body adapted for insertion in a body lumen, with a drug delivery device attached near a distal portion of the elongated body. The drug delivery device is configured to deliver a biologically active agent to stabilize a vulnerable plaque.
Abstract:
A derivatized poly(ester amide) (D-PEA) and coatings and medical devices formed therefrom are provided. The coatings and medical devices may optionally include a biobeneficial material and/or a biocompatible polymer and/or a bioactive agent. The medical devices can be implanted in a patient to treat, prevent, or ameliorate 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 prodrug comprising a heparin and a drug is provided. The prodrug can be used to form a coating on a medical device. The prodrug can also be used with a polymeric material to form a coating on a medical device. The polymeric material can be a hydrophobic polymer, a hydrophilic polymer, a non-fouling polymer, or combinations thereof. The medical device can be implanted in a human being for the treatment of a disease 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:
An implantable medical device, such as a stent, having roughened areas on an inner surface of the device for enhancing frictional contact between the medical device and a delivery system, such as a balloon catheter to secure the medical device to the delivery system during delivery of the medical device to a body lumen of a patient. Various methods for forming the roughened areas are also provided. The roughened areas may be coated with a material, such as a non-thrombogenic material, to enhance the compatibility of the inner surface of the medical device with fluid flowing through the vessel lumen of the patient.
Abstract:
Methods for modulating and enhancing thermal and mechanical properties and biocompatibilities of coatings on implantable devices are disclosed. Implantable devices containing the enhanced thermal and mechanical properties and biocompatibilities are also described. The implantable devices can be used to treat a medical condition such as vulnerable plaque or restenosis.
Abstract:
A polymer comprising phospholipid moieties and a biocompatible polymer backbone, a composition comprising the polymer and optionally a bioactive agent, an implantable devices such as a DES comprising thereon a coating comprising the polymer and optionally a bioactive agent, and a method of using the device for the treatment of a disorder in a human being are provided.
Abstract:
Coatings for an implantable medical device and a method of fabricating the coatings are disclosed. The coatings comprise a fluorinated polymer and a biologically beneficial polymer, an example of which includes poly(ethylene-glycol)-block poly(butylene terephthalate)-block poly(ethylene-glycol). A biologically active agent can be additionally conjugated to the biologically beneficial polymer.
Abstract:
A coating for a medical device, particularly for a drug eluting stent, is described. The coating can include a polyacrylate, a blend of polyacrylates, or a blend of the polyacrylate with other polymers, for example, poly(ethylene-co-vinyl alcohol).
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.
