20090112050TRANSSEPTAL CANNULA, TIP, DELIVERY SYSTEM, AND METHOD - A transseptal cannula assembly for directing blood from the heart of a patient and a minimally invasive method of implanting the same. The transseptal cannula assembly includes a flexible cannula body having proximal and distal portions with a lumen therebetween, a tip coupled to the distal portion of the flexible cannula body, and first and second anchors coupled to the tip. The anchors can be configured to be deployed from a contracted state to an expanded state and are configured to engage opposite sides of the heart tissue when in the expanded state. The anchors resist movement of the cannula assembly along a lengthwise central axis of the flexible cannula body.04-30-2009

20100232072MAGNETIC SENSOR WITH A RECESSED REFERENCE LAYER ASSEMBLY AND A FRONT SHIELD - A magnetic sensor includes a freelayer, a reference layer and a front shield. The freelayer has a magnetization direction substantially perpendicular to the planar orientation of the layer and extends to the media confronting surface. The reference layer has a magnetization direction substantially in the plane of the layer and substantially perpendicular to the magnetization direction of the freelayer. The reference layer is recessed from the media confronting surface and a front shield is positioned between the reference layer and the media confronting surface thereby reducing the shield-to-shield spacing and increasing the areal density of the reader.09-16-2010
