In some applications, the capillary is implanted for use over time, with one or more different probes being inserted into the capillary at different times, while the capillary is implanted. Certain applications involve capillary implantation over weeks, months or longer. Other applications are directed to the passage of fluid to and/or from a sample via the capillary. Still other applications are directed to the passage of electrical information between the sample and an external arrangement, via an implanted capillary.Type: GrantFiled: July 3, 2012Date of Patent: October 20, 2015Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Mark Jacob Schnitzer, Juergen Claus Jung

Patent number: 9161740Abstract: When transesophageal echocardiography is used to obtain a transgastric short axis view of the left ventricle of the heart, the best place to position the transducer is in the fundus of the stomach, aimed up through the left ventricle. The probes disclosed herein facilitate placement of the transducer in the optimum position within the fundus, despite wide variations in the distance between the lower esophageal sphincter and the fundus among different subjects. In one preferred embodiment, the ultrasound probe uses a bending section with a series of vertebrae and stiffening that is more flexible proximally and less flexible distally, which causes the probe to bend relatively sharply at the point where the probe exits the lower esophageal sphincter. The flexibility of the proximal-most portion of the bending section is preferably greater than or equal to the flexibility of the interface between the bending section and the shaft.Type: GrantFiled: April 2, 2012Date of Patent: October 20, 2015Inventor: Edward Paul Harhen
