Patent number: 9005131Abstract: Disclosed is a system and method for monitoring the breath chemistry of a patient's breath using a specially designed self-condensing sensor module mounted in a mask, nasal cannula, headband with boom apparatus, or similar device for directing the patients' breath towards the self-condensing sensor. Monitoring of a patient's breath pH provided by the miniaturized self-condensing pH sensor provides for real-time monitoring of patient airway pH values. The specially designed self-condensing sensor module incorporates a data transfer means, e.g. direct wiring or by providing a transmitter with an antenna for wireless transferring of the pH data to a processing receiver. The self-condensing pH sensor comprises a multi-tubular design with the outer tubular member housing a silver chloride reference element, an ion conducting path, and an antimony sensor plug isolated in an inner tubular member that is co-linearly or coaxially configured with the outer tubular member.Type: GrantFiled: October 10, 2006Date of Patent: April 14, 2015Inventors: Ross Tsukashima, Jeffery D.

Patent number: 8821570Abstract: Annuloplasty rings are employed to treat heart valve defects, such as regurgitation. Synching the heart tissue to the ring restores the valve opening to its approximate original size and operating efficiency. Adjustable annuloplasty rings allow for a proper degree of synching both during open heart surgery and over the patient's lifetime. A subcutaneous port may be coupled to an adjustable annuloplasty ring such that an external activation energy generator can be used to heat the adjustable annuloplasty ring and thereby adjust the size of the annuloplasty ring.Type: GrantFiled: July 20, 2010Date of Patent: September 2, 2014Assignee: MiCardia CorporationInventors: Jeffrey P.

Publication number: 20110313516Abstract: A percutaneous magnetic catheter may be used to position one or more magnetic components near a magnetically driven prosthesis in a patient's heart in order to adjust the magnetically driven prosthesis. In certain embodiments, the one or more magnetic components are rotatable. Rotation of the one or more magnetic components cause variations in a magnetic field. Variations in the magnetic field may be utilized to adjust the size or shape of a magnetically driven prosthesis. In this way, a magnetically driven prosthesis may be adjusted after a patient has recovered from a surgery in which the magnetically driven prosthesis was implanted. Further, a magnetically driven prosthesis may be adjusted based upon progression of a heart condition.Type: ApplicationFiled: February 12, 2010Publication date: December 22, 2011Applicant: MICARDIA CORPORATIONInventors: Ninh H.
