20090264539 | FLUOROPOLYMER-BASED MEDICAL IMPLANT COATING COMPOSITIONS - Polymers of fluorinated monomers and acrylate and alkyl acrylates are disclosed which demonstrate improved performance as coatings for implantable devices. Such coatings may, for example, be used to release a bioactive agent from the medical device. One specific application lies in drug-eluting coatings for stents. | 10-22-2009 |
20110263921 | Patterned Denervation Therapy for Innervated Renal Vasculature - A renal denervation apparatus includes a treatment element dimensioned for deployment on or within a renal artery of a patient. The treatment element comprises a predefined pattern arranged to complete at least one revolution of the treatment element. The apparatus includes a treatment source. The treatment source and treatment element are configured to cooperatively facilitate communication of an agent from the treatment source to the pattern arrangement of the treatment element. The treatment element is configured to deliver denervation therapy using the agent via the pattern arrangement to one or more regions of the renal artery adjacent the pattern arrangement, such that at least one complete revolution of the renal artery is subjected to the denervation therapy. | 10-27-2011 |
20110264116 | Compressive Denervation Apparatus for Innervated Renal Vasculature - Devices, systems, and methods facilitate modification of renal sympathetic nerve activity using a force generating arrangement. A device for mechanically modifying renal sympathetic nerve activity includes a contact arrangement having a shape that generally conforms to a portion of a renal artery wall and is configured for placement at the renal artery wall portion. A compression arrangement is configured to cooperate with the contact arrangement to place the wall portion of the renal artery in compression sufficient to achieve a desired reduction in renal sympathetic nerve activity. The compression arrangement and the contact arrangement are preferably configured to cooperatively place the wall portion of the renal artery in compression sufficient to irreversibly terminate renal sympathetic nerve activity. | 10-27-2011 |
20110270226 | BALLOON CATHETER DEVICES WITH SHEATH COVERING - Catheter devices having an expandable balloon for delivering a therapeutic agent to a body site. In one aspect, one or more sheaths are disposed around the balloon with the therapeutic agent being disposed within the sheath, being disposed over the sheath, being contained in the space between the sheath and the balloon, or being otherwise associated with the sheath. In another aspect, the balloon includes a micro-electromechanical system (MEMS) for drug delivery. | 11-03-2011 |

20080281395 | RATCHETING BIO CELL DESIGNS - A bifurcated stent having a side branch constructed out of a bioabsorbable material. The side branch comprises one or more bio cells which are flexible and easily deformable when the stent is in the unexpanded state. The bio cells have a locking member which fixedly holds the bio cells in place once the stent assumes the expanded state. The locking member uses oppositely directed hooks or ratchet teeth to prevent contraction in the bio cells once the expanded state is assumed. By having an appropriate alternation between flexibility and rigidity the side branch is flexible enough to deal with the geometric difficulties of bending and deploying a side branch while being fixed and rigid enough to properly support and scaffold a side branch assembly. The deployment of the side branch can be facilitated by the use of a ratcheting device. The side branch can also have a flared shape. | 11-13-2008 |
20090012596 | Stent with Bioabsorbable Membrane - In at least one embodiment, the invention is directed to a stent having a tubular wall where at least a portion of the tubular wall comprises a bioabsorbable membrane. In the portion of the tubular wall containing the bioabsorbable membrane, the members (e.g. struts and connectors) of the stent are embedded in the bioabsorbable membrane. In at least one embodiment, the stent is also configured to elute a therapeutic agent. | 01-08-2009 |
20090281615 | STENT WITH TABS AND HOLES FOR DRUG DELIVERY - A stent can include a tubular body, a plurality of circumferential serpentine bands, a plurality of connectors extending between immediately adjacent serpentine bands, and a plurality of tabs. The plurality of tabs include peak tabs and trough tabs. Each peak tab and each trough tab have a first end and a second end wherein only the first end is engaged to a serpentine band, each peak tab extends substantially parallel to the longitudinal axis from a peak on a serpentine band toward a peak on an immediately distal serpentine band. Each trough tab extends substantially parallel to the longitudinal axis from a trough on a serpentine band toward a trough on an immediately proximal serpentine band. Each serpentine band defines a plurality of holes and each tab defines a plurality of holes. The holes are constructed and arranged to contain a therapeutic agent | 11-12-2009 |
20100070023 | BIODEGRADABLE CONNECTORS - An expandable bifurcated stent is formed of a main body and a first branch. The body wall is made up of interconnected stent members that define a plurality of cells, at least one of which is a side opening. The first branch body extends from the body wall from at least two regions adjacent the side opening. At least one stent member adjacent the perimeter is bioabsorbable. | 03-18-2010 |
20140067029 | RENAL NERVE MODULATION AND ABLATION CATHETER ELECTRODE DESIGN - An intravascular nerve modulation or tissue/ablation heating system comprising an elongate shaft having a proximal end region and a distal end region, a plurality of electrodes disposed adjacent the distal end region, wherein the plurality of electrodes are configured to operate in phase. | 03-06-2014 |
20140249524 | SYSTEM AND METHOD FOR PERFORMING RENAL NERVE MODULATION - Systems and methods for monitoring and performing tissue modulation are disclosed. An example system may include an elongate shaft having a distal end region and a proximal end and having at least one ablation electrode disposed adjacent to the distal end region. The system may further include a control unit for controlling the power level and duration of the modulation procedure. | 09-04-2014 |
