CD Leycom PV Loop Catheters

Pressure-Volume Loop Catheters for Hemodynamic Measurements

Valuable insight from a single catheterization

CD Leycom pressure volume catheter for hemodynamic measurements

CD Leycom® PV Loop Catheters when used with the Inca® System, provide real-time pressure and volume data, enabling a complete assessment of cardiac function from a single catheterization.

4F conductance catheters without lumen

  • 4F, 12 electrodes, 1 pressure sensor between electrodes 5 and 6, pigtail, no lumen
  • Spacing options at 6 mm and 10 mm between the electrodes
  • Requires an appropriate sized guide catheter 

7F conductance catheters with lumen

  • 7F, 12 electrodes, 1 pressure sensor between electrodes 5 and 6, pigtail, with 0.025” guide wire lumen
  • Spacing options at 8 mm, 10 mm and 12 mm between the electrodes

CD Leycom PV Catheter List with Electrode Spacing

4F without lumen Electrode spacing Long-Axis Application
CA-41063-PN* 6 mm 35 ... 55 mm Small adults
CA-41103-PN 10 mm 45 ... 85 mm Normal adults
7F with lumen
CA-71083-PL 8 mm 38 ... 70 mm Small adults
CA-71103-PL 10 mm 45 ... 85 mm Normal adults
CA-71123-PL 12 mm 52 ... 100 mm Large adults
* Segment 3 of this catheter measures 12 mm to fit in the pressure sensor.
 

 

Catheter Length Based on Heart Size

Long-axis conductance catheter length

By adjusting the number of included segments (from 3 to maximal 7), each catheter covers
a range of heart sizes. The purple area marks the optimal choice.

 

Determining Catheter Length

How to determine required PV loop catheter length

Optimally, the effective measuring catheter length should match the ventricular long axis
(as measured by MRI and/or echocardiography).

Minimum: 4 x L + 2 x La [+10.0 (pigtail)] (mm)
Maximum: 7 x L + 2 x La [+10.0 (pigtail)] (mm)

* = Driving electrodes. The proximal driving electrodes may be positioned above the aortic valve.
L =  Electrode spacing
La = Spacing (3 mm) between the driving electrodes
