Patent number: 11478217Abstract: A catheter extension can include an extension body with a sheath defining a lumen, a cable extending within the lumen, a proximal connector attached to the sheath and configured to couple to a catheter drive mechanism, and a distal connector attached to the sheath and configured to couple to a catheter. An axial biasing member can be coupled to the cable and integrated into either the proximal or distal connector and configured to exert a force on the cable in a first axial direction and permit movement of the cable in a second axial direction. An axial key can be coupled to the cable and integrated into the connector opposite the axial biasing member. The axial key can include a tab attached to the cable and a slot with an inner profile that complements a tab outer profile that can permit the tab to move in within the slot.Type: GrantFiled: December 28, 2018Date of Patent: October 25, 2022Assignee: ACIST MEDICAL SYSTEMS, INC.Inventors: Richard A. Bautista, David Johnson, Isaac Kim

Patent number: 9782148Abstract: An ultrasound catheter includes an elongated body, a first and second ablation element each configured to ablate soft tissue and an imaging core having an ultrasound transducer. In another example, an ultrasound catheter includes an elongated body, a RF ablator configured to ablate soft tissue at a frequency less than 1 MHz, and an ultrasound transducer configured to image at a frequency greater than or equal to 10 MHz. In another example, an ultrasound catheter apparatus includes an ultrasound catheter having an ablator and an ultrasound transducer, and a graphical user interface displayed using a computer processor. The graphical user interface displays a real-time image of a treatment area and the ultrasound catheter, and a chart displaying ablation as a function of time, the chart being updated in real-time.Type: GrantFiled: November 28, 2012Date of Patent: October 10, 2017Assignee: ACIST Medical Systems, Inc.Inventors: Kendall R.

Patent number: 7366557Abstract: A catheter having an elongated catheter body including a proximal end, a distal end and at least one lumen extending longitudinally therethrough is provided. A mapping assembly is mounted at the distal end of the catheter body and includes at least two loop shaped arms. Each arm includes two ends with a loop shaped portion extending therebetween. Both ends of each arm are mounted in the distal end of the catheter body. A plurality of electrodes are mounted on each arm.Type: GrantFiled: November 7, 2003Date of Patent: April 29, 2008Assignee: Biosense Webster, Inc.Inventor: Richard Bautista

Patent number: 7155270Abstract: A catheter that is particularly useful for simultaneously mapping multiple points within the heart is provided. The catheter includes a mapping assembly including a plurality of flexible spines, each having a free distal end. The spines are supported by an improved support structure that permits the spines to be more precisely arranged relative to one another. The catheter comprises an elongated catheter body. A mapping assembly is provided at the distal end of the catheter body. The mapping assembly comprises a support structure having a generally cylindrical base mounted on the distal end of the catheter body, the base having proximal and distal ends. The support structure further comprises at least two pre-shaped flexible support arms. Each support arm has a proximal end attached to the distal end of the generally cylindrical base and a free distal end. At least two non-conductive coverings are provided, each in surrounding relation to a corresponding one of the at least two support arms.Type: GrantFiled: October 24, 2003Date of Patent: December 26, 2006Assignee: Biosense Webster, Inc.Inventors: Mario A. Solis, Richard Bautista, Robert F. Ocariz, James K. Lee, Martin O'Sullivan

Publication number: 20060209730Abstract: Two half duplex communicators from separate networks each have an audio input port, an audio output port, and a terminal for receiving an external keying signal. Audio signal paths link respective audio output ports with respective audio input ports. Voice actuated circuits produce appropriate keying signals at the keying terminals of the communicators depending on the direction of the current audio signals. Preferably the keying circuits each include an audio amplifier having an adjustable gain, and a switching circuit responsive to a signal from the amplifier above a certain threshold for producing the keying signal, and preferably include a time delay circuit for delaying drop-out of the keying signals for a preset time after the amplifier signal has fallen below the threshold to prevent prematurely cutting-off audio before the speaker is finished talking.Type: ApplicationFiled: March 19, 2005Publication date: September 21, 2006Inventor: Richard Bautista

Publication number: 20040059228Abstract: Various improvements are made to catheters adapted to be flushed to remove air from within the catheter. For example, improved catheters include a catheter with a self-sealing seal at its distal end to pass a venting tube for removing air from within the catheter, a catheter having a distal end whose diameter is reduced to compress a seal adapted to pass a venting tube; a catheter having a cap at its distal end where the cap has a venting hole that is opened or closed depending on the conditions subjected to the shape-memory material of the cap; a catheter having a vent hole at its distal end; a catheter having an opening at its distal end that can be closed by a plug; and a catheter having a narrow neck with an opening to vent air and the neck is coupled to a tab where twisting the tab closes the opening in the neck.Type: ApplicationFiled: September 23, 2002Publication date: March 25, 2004Applicant: Scimed Life Systems, Inc.Inventors: Lawrence Wasicek, Richard A.

Patent number: 6287261Abstract: The present invention provides ultrasound transducers, and imaging assemblies and catheters employing such transducers, that provide improved imaging capabilities. In one embodiment, an ultrasound imaging assembly (50) includes a housing having a distal end (56), a proximal end (57) and a longitudinal axis. A transducer element (54) is included having an outer face. The outer face has a first radius of curvature along a first axis and a second radius of curvature along a second axis. The transducer element is operably attached to the distal end to position the first axis to be generally parallel to the longitudinal axis to provide improved cross-plane resolution.Type: GrantFiled: July 21, 1999Date of Patent: September 11, 2001Assignee: Scimed Life Systems, Inc.Inventors: Veijo T. Suorsa, Dennis Mendoza, Richard Bautista

Patent number: 6186952Abstract: In one embodiment, an ultrasound imaging assembly (80) includes a housing (82) having a longitudinal axis (88), a proximal end (86), and a distal ending (84) defining a receptacle (90). The imaging assembly includes a transducer package (60) having a central axis (62) and an imaging surface (66) positioned at a desired angle (106) relative to the central axis. The transducer package is at least partially disposed within the receptacle so that the central axis is generally perpendicular to the longitudinal axis. Such a configuration permits a relatively large percentage of the ultrasound signal to pass through a sheath (120) surrounding the imaging assembly and reduces assembly-to-assembly variations.Type: GrantFiled: January 4, 2000Date of Patent: February 13, 2001Assignee: SciMed Life Systems, Inc.Inventors: David A. White, Donald S. Mamayek, Richard A. Bautista
