20100100044 | Splittable Valved Introducer Apparatus - An improved splittable medical device introducer designed to introduce a medical device such as a lead or catheter, into a patient's vasculature without loss of blood or the introduction of air is described. The introducer assembly is designed to easily separate in a smooth tactile manner without disrupting placement of the medical device during removal of the introducer. The introducer is composed of a fluoropolymeric material which combined with an internal stress confining structure propagates a stress initiated by the operator that tears the entire introducer assembly in two without creating a jagged separated edge. | 04-22-2010 |
20100100164 | CAPACITOR AND INDUCTOR ELEMENTS PHYSICALLY DISPOSED IN SERIES WHOSE LUMPED PARAMETERS ARE ELECTRICALLY CONNECTED IN PARALLEL TO FORM A BANDSTOP FILTER - One or more inductors and one or more capacitors are physically disposed relative to one another in series and are electrically connected to one another in parallel to form a bandstop filter. Chip inductors and chip capacitors having spaced apart conductive terminals are physically arranged in end-to-end abutting relation to minimize electrical potential between adjacent conductive terminals. The bandstop filter may be hermetically sealed within a biocompatible container for use with an implantable lead or electrode of a medical device. The values of the inductors and the capacitors are selected such that the bandstop filter is resonant at one or more selected frequencies, such as an MRI pulsed frequency. | 04-22-2010 |
20100114281 | MRI CONDITIONALLY SAFE LEAD EXTENSION AND METHODS - Lead extensions, systems, and methods providing MRI compatible deep brain stimulation (DBS) and spinal cord stimulation (SCS) systems are described. Lead extensions are provided having band stop filters (BSFs) which resonate at a frequency expected from MRI systems to create a very high impedance which can effectively decouple the implanted lead from the lead extension proximal of the BSF and change the effective length. Changing the effective length can reduce the likelihood of undesirably heating tissue near the DBS/SCS electrodes during MRI. Some lead extensions include BSFs in a distal connector for coupling to the lead contacts. The BSFs can be included within a burr hole cap base which can also include a connector for connecting to the DBS lead. DBS and SCS leads having a sacrificial proximal portion and intermediate electrical contacts are also provided. | 05-06-2010 |

20100286766 | SURFACE MODIFICATION FOR COATING - A modified medical device substrate surface designed to improve adhesion of biomimetic surfactants to the medical device surface, thus reducing the risk of thrombosis is described. The surface modification is accomplished through either an application of a tie layer of a hydrophobic material on the substrate surface intermediate the biomimetic coating or through incorporation of a hydrophobic dopant in the polymeric substrate prior to extrusion or molding. Either method creates a hydrophobically modified surface that enhances the biomimetic surfactant bonding strength. | 11-11-2010 |
20100316787 | Biomimetic Coating Method - A modified method of preparing and applying a biomimetic coating to a medical device substrate surface is described. The modified biomimetic coating method utilizes a solvent mixture of water and an organic water miscible solvent that results in a more efficient coating process, reducing the time required to apply a sufficiently adherent biomimetic coating. | 12-16-2010 |

20140031909 | MINIMALLY INVASIVE METHODS FOR IMPLANTING A SACRAL STIMULATION LEAD - Methods and apparatus for implanting a neural stimulation lead in a patient's body are described. A lead assembly comprises a pointed-tip stylet, a stimulation lead, and an optional tube to deploy a fixation element attached to the lead. One embodiment of the implant methods starts with inserting the pointed-tip lead assembly directly into tissue. After the desired implant position is determined, the pointed-tip component is separated from the stimulation lead and removed from the tissue, leaving the stimulation lead implanted. After confirmation that the stimulation lead is in the right, tissue location, the pointed-tip component is removed from the body, leaving the stimulation lead in place. The stimulation lead can be connected to a neurostimulator to delivery therapies to treat neural disorders, such as urinary control disorders, fecal control disorders, sexual, dysfunction, and pelvic pain, etc. | 01-30-2014 |
