Patent number: 8855734Abstract: In an embodiment, a sensor may be adapted to provide information related to its position on a patient's tissue. The sensor may include tissue contact sensors which may relay a signal related to the proper placement of the sensor relative to the tissue of a patient. Such a sensor may be useful for providing information to a clinician regarding the location of the sensor in relation to the skin of a patient in order to provide improved measurements.Type: GrantFiled: December 17, 2012Date of Patent: October 7, 2014Assignee: Covidien LPInventors: Paul D. Mannheimer, Bruce R. Bowman, Lee M. Middleman, Clark R. Baker, Jr.

Patent number: 7169160Abstract: The present invention is directed to an apparatus for anchoring a tubular element, preferably in the form of a catheter, within a passageway formed in a mammalian body, such as in a vessel, artery, duct, channel, or the like. The apparatus comprises a tubular element having a flexible, elongated, hollow tubular outer lumen with a central longitudinal axis extending therethrough, the outer lumen having a proximal end and a distal end. The apparatus further comprises deployment means positioned within the outer lumen and slidable with respect to the outer lumen. The deployment means has a proximal end and a distal end. The apparatus further comprises a plurality of resilient anchoring members preferably formed of a pseudoelastic material. The anchoring members are coupled to the distal end of the deployment means and extend longitudinally beyond the distal end of the deployment means. Each anchoring member is reversibly movable by the deployment means between a first position and a second position.Type: GrantFiled: July 28, 1998Date of Patent: January 30, 2007Assignee: Medtronic, Inc.Inventors: Lee M.

Patent number: 5345937Abstract: A device suitable for insertion into a mammalian body comprises an elongated tube or cannula, an elastic member for bending the cannula, and a straightener preventing the elastic member from bending the cannula. The straightener and elastic member are capable of relative axial movement, so that the elastic straightener can be positioned to prevent or allow the elastic from bending the cannula. Preferably the elastic member is formed from a superelastic shape-memory alloy. Other versions of the device without a straightener are described.Type: GrantFiled: July 28, 1993Date of Patent: September 13, 1994Assignee: Raychem CorporationInventors: Lee M. Middleman, Walter R.
