| 20080293135 | Co-Culture Bioreactor System - Disclosed are multi-chambered cell co-culture systems. The systems can be utilized to encourage the growth and development of isolated cells in a dynamic three-dimensional in vitro environment. The cell chambers ( | 11-27-2008 |
| 20090142505 | Needle-to-Needle Electrospinning - The disclosure relates to a method and apparatus for coating a medical device. The method includes providing an electrospinning apparatus and simultaneously electrospinning at least one solution onto a first surface and an opposing second surface. The apparatus comprises a first spinneret and a second spinneret. An energy source is electrically coupled to the first spinneret and the second spinneret. The first spinneret and second spinneret comprise a reservoir and an orifice fluidly coupled to the reservoir. The first spinneret orifice is located substantially opposite the second spinneret orifice. | 06-04-2009 |
| 20090215176 | Differential Pressure Pump System - The present disclosure is directed to a fluid pumping mechanism that uses differential pressure to drive flow through one or more culture chambers. Fluid contained within a first chamber can be caused to flow through one or more culture chambers and thence to a second chamber upon establishment of a pressure differential between the two chambers. The differential pressure system can induce either steady state or pulsatile flow through a culture chamber. In one embodiment, a culture chamber can be held at a high or low pressure hydrostatic state through utilization of the disclosed systems. | 08-27-2009 |
| 20100057195 | BARBED ANCHORS FOR WIRE STENT - An endoluminal prosthesis that includes a support structure comprising a curvilinear portion having a first strut and a second strut that meet at an apex. Disposed on the support structure is an anchor with an anchor body and one or more barbs extending outwardly from the anchor body and where the anchor body fits at least partially about, and conforms to the first strut, second strut, and the apex. | 03-04-2010 |
| 20100323052 | NEEDLE-TO-NEEDLE ELECTROSPINNING - The disclosure relates to a method and apparatus for coating a medical device. The method includes providing an electrospinning apparatus and simultaneously electrospinning at least one solution onto a first surface and an opposing second surface. The apparatus comprises a first spinneret and a second spinneret. An energy source is electrically coupled to the first spinneret and the second spinneret. The first spinneret and second spinneret comprise a reservoir and an orifice fluidly coupled to the reservoir. The first spinneret orifice is located substantially opposite the second spinneret orifice. | 12-23-2010 |

| 20100152835 | Tapered Stent and Flexible Prosthesis - The disclosure relates to a tapered stent and flexible prosthesis. The stent has a first longitudinal region and a second longitudinal region. The second region is substantially parallel to and spaced axially apart from the first region. A plurality of struts is disposed intermediate the first region and the second region and circumferentially connects the first region and the second region. The first region has a longitudinal length that is greater than the second region longitudinal length. The struts have varying longitudinal lengths that gradually decrease from the first region to the second region. The flexible prosthesis comprises at least two alternating tapered stents. | 06-17-2010 |
| 20100161027 | STENT AND STENT-GRAFT HAVING ONE OR MORE CONFORMANCE STRUTS - A stent includes a main body having proximal and distal ends, and at least one conformance strut coupled to the proximal end of the main body. A portion of the at least one conformance strut extends proximal to a proximal end of a graft material in a compressed delivery configuration, and further is aligned inside the proximal end of the graft material in an expanded deployed configuration. In the deployed configuration, the proximal conformance strut may at least partially encircle the graft material just distal to the proximal end of the graft material, which may reduce the likelihood of infolding at the proximal edge of the graft material and potential endoleaks. | 06-24-2010 |

| 20080214114 | INVERSION OF CHANNEL DISTORTION BY ADAPTIVE WAVELET LIFTING - A method for inverting telecommunication channel distortion by adaptive wavelet lifting. The distortion signal is analyzed using wavelet lifting and the inverse filter is computed. Coefficients of the inverse filter are used to either compute a transmission pre-filter or to update the transmitted message. | 09-04-2008 |
| 20090014045 | Appliance for cell-phones, laptops and PDAs - In a first aspect of the invention, a power source comprising an electrical charging device comprising a thermal conductor, a thermoelectric source (TES) for converting thermal energy into electrical energy, and a battery for accumulating electrical charge generated by the converter. The battery provides electrical power to a cell-phone, laptop computer or the like. In a second aspect of the invention, an RFID tag is attached to the cell-phone, laptop or the like to prevent loss or theft. | 01-15-2009 |

| 20110137403 | INTRODUCER FOR ENDOVASCULAR IMPLANTS - An introducer assembly for introducing a stent-graft or other device into a vessel of a patient is provided with a dilator tip which is naturally curved, preferably to be substantially a U-shape. The dilator tip is flexible so as to be able to become substantially straight with a guide wire therein and yet to be able to curve back towards its natural curvature during deployment of an implant. The curvature of the dilator tip can ensure that the dilator tip does not cause damage to the vessel wall during deployment of an implant carried thereon, as can occur with straight dilator tips. | 06-09-2011 |
| 20110166516 | BALLOON CATHETERS HAVING A PLURALITY OF NEEDLES FOR THE INJECTION OF ONE OR MORE THERAPEUTIC AGENTS - There are disclosed apparatus and methods for treating tissue by delivering at least one therapeutic agent into the tissue. In one embodiment, the apparatus comprises a catheter ( | 07-07-2011 |
