Further study details as provided by C. R. Bard:

Primary Outcome Measures:
  • Phase I - to determine the location of the PICC tip upon observation of maximum p-wave amplitude using Sherlock 3CG. [ Time Frame: Time of PICC placement (Day 0) ] [ Designated as safety issue: No ]
    To determine the mean distance from the PICC tip to the upper cavoatrial junction upon observation of maximum p-wave amplitude when using Sherlock 3CG.

  • Phase II - To determine the precision of PICC placement in the Sherlock 3CG group (treatment arm) relative to the blind placement group (control arm) using the upper cavoatrial junction as an anatomical landmark. [ Time Frame: Time of PICC placement (Day 0) ] [ Designated as safety issue: No ]
    to determine the mean distance from the PICC tip to the upper cavoatrial junction, as measured by the qualified radiology practitioner based on ACT imaging. Mean distances will be calculated for both the Sherlock 3CG group and the blind placement group.


Secondary Outcome Measures:
  • Phase I: To evaluate the distance necessary for repositioning, if necessary, of the PICC tip upon observation of the maximum p-wave amplitude [ Time Frame: Day 0 ] [ Designated as safety issue: No ]
    To determine the mean distance of the PICC tip to the upper cavoatrial junction following repositioning, if necessary.

  • Phase I: To assess capability of Angiographic CT to image the PICC tip when using Sherlock 3CG for PICC placement [ Time Frame: Day 0 ] [ Designated as safety issue: No ]

    To determine the proportion of acceptable visualization of the PICC tip location when maximum p-wave amplitude is observed.

    Note - this endpoint is to assess the diagnostic capability of ACT. It is not designed to reflect on PICC tip location.


  • Phase I: To determine if there is a difference in the location of the cavoatrial junction on Angiographic CT performed with the arms above the head or at the subject's side. [ Time Frame: Day 0 ] [ Designated as safety issue: No ]
    To determine whether measurements of the location of the cavoatrial junction on Angiographic CT differs by greater than 5mm between acquisitions obtained with the arms above the head & arms at the side of the subject.

  • Phase I: To determine the amount of PICC tip movement when the subject's arm is adducted from a 90° position to the subject's side. [ Time Frame: Day 0 ] [ Designated as safety issue: No ]
    To determine the mean distance of PICC tip movement when the subject's arm is adducted from a 90° position to the subject's side.

  • Phase II: To assess adverse events associated with the use of Sherlock 3CG for PICC placement. [ Time Frame: 30 Days post procedure ] [ Designated as safety issue: Yes ]
    To determine the proportion of subjects experiencing device-or-procedure related adverse events in the Sherlock 3CG group and in the blind placement group.

  • Phase II: To determine the success rate of placing the PICC tip into an acceptable position using the Sherlock 3CG, as judged by the qualified radiology practitioners. [ Time Frame: Day 0 ] [ Designated as safety issue: No ]
    To determine the proportion of subjects in whom the PICC tip was in an acceptable position in the Sherlock 3CG group and in the blind placement group.

  • Phase II: To determine the number of radiographs received in each subject group. [ Time Frame: Day 0 ] [ Designated as safety issue: No ]
    To assess the mean number of spot images that are used in the Sherlock 3CG and in the blind placement group.

  • Phase II: To determine the amount of radiation received in each subject group. [ Time Frame: Day 0 ] [ Designated as safety issue: No ]
    To determine the mean radiation received by the Sherlock 3CG and blind placement groups.

Study Start Date: January 2011
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Sherlock 3CG
Sherlock 3CG is indicated for central venous catheter guidance and positioning during catheter placement. The Sherlock 3CG provides real time catheter tip location information through the use of passive magnet and cardiac electrical signal detection.
Device: Sherlock 3CG
Sherlock 3CG is indicated for central venous catheter guidance and positioning during catheter placement. The Sherlock 3CG provides real time catheter tip location information through the use of passive magnet and cardiac electrical signal detection.
Active Comparator: "Blind" Placement
PICCs will be placed "blindly", without the use of any tip location/positioning device.
Other: Blind Placement
PICCs will be placed "blindly", without the use of any tip location/positioning device.
