| 20090062483 | NANOPARTICLE PRECURSOR STRUCTURES, NANOPARTICLE STRUCTURES, AND COMPOSITE MATERIALS - Nanoparticle precursor structures, nanoparticle structures, and composite materials that include the nanoparticle structures in a polymer to form a composite material. The nanoparticle structures have chemical linkage moieties capable of forming non-covalent bonds with portions of a polymer for the composite material. Such composite materials are useful as biomaterials in medical devices. | 03-05-2009 |
| 20100100057 | POLYMER COATINGS WITH CATALYST FOR MEDICAL DEVICES - Coating compositions and coatings for medical devices formed from the coating compositions that include a catalyst in a support polymer, where the support polymer helps to support and retain the catalyst in the coating on the medical device. The catalyst in the support polymer can act to chemically bond specific compounds migrating from a body of the medical device formed from a polymer to at least one of the polymer and/or other specific compounds migrating from the body of the medical device. | 04-22-2010 |

| 20090099634 | CONDUCTIVE COMPOSITE ELECTRODE MATERIAL - A medical electrical lead and body implantable electrode suitable for a variety of medical applications are disclosed. In general, the electrode includes a composite material having particles of pseudo-capacitive material, such as iridium oxide, dispersed within a polymer matrix including a polyelectrolyte. The polymer matrix can also include a conductive polymer doped with an excess of the polyelectrolyte. The composite may used to form the electrode itself or an electrode coating. The presence of a pseudo-capacitive material within the composite may increase the charge-storage capacity of the electrode and may allow for safe deliveries of charge densities within an electrochemical window suitable for pacing a patient's heart. | 04-16-2009 |
| 20090105796 | FIBROUS ELECTRODE MATERIAL - A biomimetic electrode material including a fibrous matrix including a conductive polymer and an ion conducting polymeric material is described. The biomimetic electrode material may be used in a number of body-implantable application including cardiac and neuro-stimulation applications. The biomimetic electrode material can be formed using electrospinning and other related processes. The biomimetic electrode may facilitate efficient charge transport from ionically conductive tissue to the electronically conductive electrode and may induce surrounding tissue to attach or interface directly to the implanted device, increasing the biocompatibility of the device. | 04-23-2009 |
