20110092911 | Splittable cannula having radiopaque marker - A splittable cannula includes a radiopaque marker placed at or near the distal end of the cannula. The radiopaque marker may be a unitary piece, or may consist of several portions. The cannula may include a sheath or catheter body with a grooved score line running along a portion of the sheath body and a radiopaque marker located at a distal end of the body and abutting the body. The radiopaque marker may be located within the lumen of the sheath, may be embedded in the sheath wall, or may be affixed to the external sheath wall. The radiopaque marker may be scored, notched, grooved, or contain apertures longitudinally. The notches, grooves, apertures, and/or score lines in both the sheath or catheter body and the radiopaque marker serve to provide a weakened tear path. An electrode lead may be coupled with the radiopaque marker. | 04-21-2011 |

The compression ring can be located around the catheter shaft to compress the catheter shaft against an outer surface of the mounting shaft, or within the catheter shaft to compress the catheter shaft outwardly against an inner surface of the mounting shaft. The catheter can be a non-irrigated ablation catheter, with the tip element being a tip electrode, and it can be an irrigated ablation catheter, with the distal tip including a fluid manifold. | 12-27-2012 |
20130172712 | ELECTRICALLY TRANSPARENT INTRODUCER SHEATH - An introducer sheath for a medical device is provided. The sheath includes a deformable, elongate body disposed about a longitudinal axis. The body has proximal and distal ends and defines a lumen extending between the proximal and distal ends and configured to allow passage of the medical device therethrough. The body is configured to allow an electric current to pass radially between a space outside of the body and the lumen such that the position of the medical device within a patient can be monitored and electrogram readings from body tissues can be measured while the device is in the sheath. In some embodiments of the invention, the body may include a one or more apertures extending from the radially outer surface of the body to the lumen or a portion of the body may be made from a conductive and/or fluid permeable material. | 07-04-2013 |
20130172821 | CATHETER INSERTION DEVICES - A catheter insertion device is provided that comprises an elongate member defining a longitudinal axis. The elongate member is configured to be disposed on a catheter in one of a first configuration and a second configuration. The first configuration and the second configuration are different. The catheter insertion device is further configured to allow the elongate member to be selectively and repeatedly reconfigured between the first configuration and the second configuration while disposed on the catheter. | 07-04-2013 |
20140100566 | Medical catheter assembly with deflection pull ring and distal tip interlock - A catheter assembly comprises a deflectable catheter shaft comprising a distal end and a lumen extending therethrough. The catheter assembly further comprises least one pull wire comprising a distal portion comprising a side and a distal end, wherein the side comprises a first side portion and a second side portion. The catheter assembly further comprises a distal pull assembly operatively coupled to the at least one pull wire. The distal pull assembly comprises a longitudinal axis, a first surface, and a second surface. The first side portion of the at least one pull wire is adjacent to the first surface of the distal pull assembly, and the second side portion of the at least one pull wire is adjacent to the second surface of the distal pull assembly. | 04-10-2014 |
20140157573 | METHOD OF MANUFACTURING A PEELABLE ATRAUMATIC TIP AND BODY FOR A CATHETER OR SHEATH - A method of manufacturing a splittable/peelable tubular body of a catheter or sheath wherein the tubular body has a splittable/peelable atraumatic tip is disclosed. The atraumatic tip is generally softer than the tubular body. The tubular body and atraumatic tip each comprise a peel mechanism longitudinally extending along their respective lengths. The peel mechanisms are formed by longitudinally extending regions of interfacial bonding between first and second longitudinally extending strips of polymer material. Each strip forms at least a portion of an outer circumferential surface of the tubular body and atraumatic tip. A region of stress concentration extends along the region of interfacial bonding. The stress concentration facilitates the splitting of the tubular body and atraumatic tip along their respective peel mechanisms. | 06-12-2014 |
20140275991 | SYSTEM FOR DETECTING CATHETER ELECTRODES ENTERING INTO AND EXITING FROM AN INTRODUCER - Systems for detecting when catheter electrodes enter into and exit from an introducer are disclosed. In one form, a system detects a relative position of a catheter (comprising a marker band and an electrode) and an introducer (comprising a proximity sensor adapted to sense the marker band), while the catheter and introducer are in a human body. The system may comprise an electronic control unit to analyze signals from the catheter and/or the introducer, to determine whether the catheter electrode is within the introducer; and to disregard data collected from the electrode when that electrode is in the introducer. The sensor may be on the catheter and the sensed element may be on the introducer. The sensed element may comprise one or several marker bands. A marker band may be applied during the manufacture of a medical device or during its use and is any element capable of electromagnetic detection. | 09-18-2014 |

20100266192 | COUNTING BIOLOGICAL AGENTS ON BIOLOGICAL GROWTH PLATES - The invention is directed to counting techniques for counting biological agents on a biological growth plate or similar medium. In order to automate the counting of biological agents, a biological growth plate is inserted into a biological scanning unit. Upon insertion of the biological growth plate, the biological scanning unit generates an image of the plate. Then, the amount of biological agents that appear in the image, such as a number of bacteria colonies, can be counted or otherwise determined using image processing and analysis routines performed either by the scanning unit or an external computing device, such as a desktop computer, workstation or the like. A variety of counting rules are described herein that can be used to improve the accuracy of automated counts of biological agents on a biological growth plate. | 10-21-2010 |
