Patent number: 9554716Abstract: A guidance system for assisting with the insertion of a needle or other medical component into the body of a patient is disclosed. The guidance system utilizes ultrasound imaging or other suitable imaging technology. In one embodiment, the guidance system comprises an imaging device including a probe for producing an image of an internal body portion target, such as a vessel. One or more sensors are included with the probe. The sensors sense a detectable characteristic related to the needle, such as a magnetic field of a magnet included with the needle. The system includes a processor that uses data relating to the detectable characteristic sensed by the sensors to determine a position and/or orientation of the needle in three spatial dimensions. The system includes a display for depicting the position and/or orientation of the needle together with the image of the target.Type: GrantFiled: May 27, 2011Date of Patent: January 31, 2017Assignee: C.

Patent number: 9526440Abstract: An integrated catheter placement system for accurately placing a catheter within a patient's vasculature is disclosed. In one embodiment, the integrated system comprises a system console, a tip location sensor unit for temporary placement on the patient's chest, and an ultrasound probe. The tip location sensor senses a field produced by a stylet disposed in a lumen of the catheter when the catheter is disposed in the vasculature. The ultrasound probe ultrasonically images a portion of the vasculature prior to introduction of the catheter. ECG signal-based catheter tip guidance is included to enable guidance of the catheter tip to a desired position with respect to a node of the patient's heart. The stylet includes an electromagnetic coil that can be operably connected to the sensor unit and/or console through a sterile barrier without compromising the barrier. The stylet can also be wirelessly connected to the sensor unit and/or console.Type: GrantFiled: June 19, 2014Date of Patent: December 27, 2016Assignee: C.R. Bard, Inc.Inventors: Eddie K.

Publication number: 20160360989Abstract: A catheter assembly including one or more conductive pathways is disclosed. The conductive pathways assist with initial placement of the catheter assembly into a patient's vasculature by enabling ECG signals emanating from the patient's heart to be detected. In addition, the conductive pathways are configured to be used to reconfirm via ECG signal detection proper placement of the catheter assembly at a time subsequent to initial catheter placement into the vasculature. In one embodiment, therefore, a catheter assembly is disclosed, comprising an elongate catheter tube defining at least one lumen, a first conductive pathway extending distally from a proximal point on the catheter assembly to a predetermined distal location on the catheter tube, and a second conductive pathway at least partially disposed on an outer surface of the catheter tube and extending distally from a proximal point of the catheter assembly to a predetermined distal location on the catheter tube.Type: ApplicationFiled: June 9, 2016Publication date: December 15, 2016Inventors: Dennis L.

Patent number: 9415188Abstract: A system and method for guiding a catheter or other medical device to a desired target destination within the vasculature of a patient via bioimpedance measurements is disclosed. The target destination in one embodiment includes placement of the catheter such that a distal tip thereof is disposed proximate the heart, e.g., the junction of the right atrium and superior vena cava. In one embodiment the method for guiding the catheter comprises introducing the catheter into a vessel of the patient, the catheter defining a lumen through which fluids can be infused into the vasculature of the patient. The catheter is advanced toward a target destination within the vasculature. A first impedance value based on intravascular detection of at least one electrical property related to a first tissue surface of the vessel is calculated to enable determination of the proximity of a distal end of the catheter to the target destination.Type: GrantFiled: July 31, 2014Date of Patent: August 16, 2016Assignee: C. R. Bard, Inc.Inventors: Ding Sheng He, David J. Ciavarella, Eddie K. Burnside, Kevin W. Stinger

Publication number: 20150101616Abstract: A procedure kit that removably retains components to be used during a medical procedure, such as the insertion of a catheter into a patient, is disclosed. The procedure kit is securable to a surface or structure such that the kit is positioned as desired by the clinician, thus minimizing chances that the kit will fall to the ground or undesirably move. In one embodiment, the procedure kit comprises a body defining a plurality of pockets that are sized to removably receive therein components for use in the medical procedure, an openable flap that covers at least a portion of the pockets; and an adhesive portion included on a portion of the body to enable the procedure kit to be secured to a structure or surface proximate to the patient, such as the sterile drape covering the patient.Type: ApplicationFiled: October 10, 2014Publication date: April 16, 2015Inventors: Martha R. Wiley, Heather R. Murphy, Angela D. Grosklags, Eddie K. Burnside, Kelly J. Christian, Bradley W. Zentgraf, Russell L. Bjorklund

Patent number: 8971994Abstract: A method for displaying a position of a medical device, such as a catheter, during insertion thereof into a patient. In one example embodiment, the method includes obtaining a first set of detected position data relating to a location marker, such as a permanent magnet, then determining a possible first position thereof. A first confidence level relating to a match between the first set of detected position data and a first set of predicted position data is assigned. A determination is made whether the first confidence level meets or exceeds a first threshold. If the first confidence level meets or exceeds the first threshold, a determination is then made whether the first position of the location marker is within a first detection zone. If the first position of the location marker is within the first detection zone, the first position of the location marker is displayed.Type: GrantFiled: April 8, 2013Date of Patent: March 3, 2015Assignee: C.

Publication number: 20150025465Abstract: A sacrificial catheter assembly and method of use for placing a functional catheter within the body of a patient, such as into the patient's vasculature, is disclosed. In one embodiment, the sacrificial catheter assembly comprises a sacrificial catheter including an elongate body that defines a longitudinally extending lumen. A stylet is removably received within the lumen of the sacrificial catheter such that the catheter and stylet can be advanced together to a target destination within the body of the patient. The sacrificial catheter is configured so as to then be proximally slid over the stylet to remove the sacrificial catheter from the body while the stylet remains in place at the target destination. A functional catheter can then be distally slid over the stylet to place the functional catheter at the target destination. The stylet can then be removed from the body of the patient.Type: ApplicationFiled: October 6, 2014Publication date: January 22, 2015Inventors: David J. Ciavarella, Eddie K. Burnside, Kelly B. Powers

Publication number: 20140330118Abstract: An assembly for identifying a power injectable vascular access port, including a vascular access port and an identification feature. The port is structured for power injection and includes a housing and a septum together defining a reservoir. A radiographic feature incorporated into the port is perceivable via x-ray following subcutaneous implantation, the radiographic feature identifying the port as suitable for flowing fluid at a fluid flow rate of at least 1 mL/sec therethrough. A structural feature of the port is perceivable via palpation following subcutaneous implantation, the structural feature identifying the port as suitable for accommodating a pressure within the reservoir of at least 35 psi. The identification feature is separated from the port and confirms that the port is both suitable for flowing fluid at a rate of at least 1 mL/sec therethrough and suitable for accommodating a pressure within the reservoir of at least 35 psi.Type: ApplicationFiled: February 3, 2014Publication date: November 6, 2014Applicant: C.
