| 20090082827 | HINGED ANCHORS FOR WIRELESS PACING ELECTRODES - A hinged anchor for a medical device electrode is disclosed. In one embodiment, the hinged anchor has a hinged portion and an anchor portion. The hinged portion can have a first configuration forming a first angle and a second configuration forming a second angle. The second angle can be a sharper angle than the first angle, and the hinged portion can be predisposed to assume the second configuration. The hinged anchor can be disposed on a control module of a leadless microstimulator device. | 03-26-2009 |

| 20090099526 | IMPLANTABLE CATHETER PORT - A single or multi-port vascular access device including one or more reservoirs each covered by a needle-penetrable, self-sealing septum. The one or more reservoirs each open to an outlet in a stem to which the catheter is attached. The reservoir may be generally circular or ellipsoid in shape and large enough so that fluid movement into and out of the needle is unimpeded. In order to maximize flow between the reservoir and catheter and to minimize any regions of impeded or low fluid flow where coagulation or cell shearing may occur, the fluid passage leading from the reservoir through the outlet into the catheter is defined by unique tapered and tangential geometries. For example, the outlet surface may be globally tangent along the entire reservoir surface, or may be globally tangent along only one side of the reservoir surface. | 04-16-2009 |
