Publication number: 20160100885Abstract: A catheter and method for the treatment of a patient having atrial flutter or other arrhythmia comprises an elongated catheter body having an outer wall, proximal and distal ends, and at least one lumen extending therethrough. Further it has a distal tip section comprising a flexible tubing having a proximal end and a distal end and a plurality of lumens extending therethrough. The proximal end of the tip section is fixedly attached to the distal end of the catheter body. The tip section further comprises a nitinol tube having slots formed therein which causes the distal tip section to deflect using the same puller-wire action used to cause the deflectable catheter to deflect at a point proximal to the distal tip section.Type: ApplicationFiled: December 17, 2015Publication date: April 14, 2016Inventors: Keshava Datta, Mario A.

Patent number: 7862517Abstract: A localization mechanism, or fixture, is used in conjunction with a breast coil for breast compression and for guiding a core biopsy instrument during prone biopsy procedures in both open and closed Magnetic Resonance Imaging (MRI) machines. The localization fixture includes a three-dimensional Cartesian positionable guide for supporting and orienting an MRI-compatible biopsy instrument, and in particular a sleeve, to a biopsy site of suspicious tissues or lesions. A depth stop enhances accurate insertion, and prevents over-insertion or inadvertent retraction of the sleeve. The sleeve receives a probe of the MRI-compatible biopsy instrument and may contain various features to enhance its imagability, to enhance vacuum and pressure assist therethrough, and marker deployment etc.Type: GrantFiled: August 6, 2007Date of Patent: January 4, 2011Assignee: Devicor Medical Products, Inc.Inventors: Mark Tsonton, Timothy G.
