  • Publication number: 20030205739
    Abstract: In one aspect, the invention provides semiconductor sensor which includes a first single crystal silicon wafer layer. A single crystal silicon structure is formed in the first wafer layer. The structure includes two oppositely disposed substantially vertical major surfaces and two oppositely disposed generally horizontal minor surfaces. The aspect ratio of major surface to minor surface is at least 5:1. A carrier which includes a recessed region is secured to the first wafer layer such that said structure is suspended opposite the recessed region.

  • Publication number: 20020169466
    Abstract: A connector for use in providing an anastomotic connection between two tubular body fluid conduits in a patient is provided. The connector is preferably a single, integral structure that can be cut from a tube. The connector has axially spaced portions that include “fingers” for engaging the two body fluid conduits. The connector also has members that have sharpened end portions that engage and penetrate the wall of one of the body fluid conduits. The fingers and sharpened members hold the two conduits together in a fluid-tight engagement. Apparatus for use in deploying a connector is also disclosed.

  • Publication number: 20020082614
    Abstract: Instrumentation for facilitating cutting an opening in a side wall of a body conduit in a patient. A tubular structure defines a lumen and has a sharpened distal end portion configured to cut a section of the body conduit to create the opening. A tissue holding structure is provided which is axially movable within the lumen of the tubular structure. The tissue holding structure includes a piercing portion to permit passage of the tissue holding structure through the body conduit from an entrance side to an exit side thereof. The tissue holding structure also includes a retention member to secure the section of the body conduit to the tissue holding structure during movement of the tissue holding structure to approximate the entrance side of the body conduit with the sharpened distal portion of the tubular structure to enable the sharpened distal structure to cut the body conduit. A connector is also provided for attaching a new length of tubing to the body conduit at the opening made by the cutting.

  • Patent number: 6316796
    Abstract: In one aspect, the invention provides a semiconductor sensor which includes a first single crystal silicon wafer layer. A single crystal silicon structure is formed in the first wafer layer. The structure includes two oppositely disposed substantially vertical major surfaces and two oppositely disposed generally horizontal minor surfaces. The aspect ratio of major surface to minor surface is at least 5:1. A carrier which includes a recessed region is secured to the first wafer layer such that said structure is suspended opposite the recessed region.
