Standard R-JVC / R-CAC Catheter |
|
Rat Thoracic
Catheter
Suitable
for blood sampling and/or drug infusion in either the jugular vein or
carotid artery of the rat.
Please note that the
RenaSil™
intravascular tip length should be sized for optimum performance.
When cannulating the jugular vein, the catheter tip should
reside at the entrance of the right atrium (Waynforth and Flecknell,
1991). When cannulating
the carotid artery, the catheter tip should reside within the
descending aortic arch (Waynforth and Flecknell, 1991).
Standard intravascular tip length is 32
mm for the R-JVC and 26 mm for the R-CAC. Please specify any
changes to these specifications when orderingRat Thoracic Jugular Vein

Specifications:
Port
Length: 20-25 mm; Catheter Body Length: 55-65 mm;
Intravascular Tippet Length:
32 mm
Procedural
Overview: Jugular Vein Catheterization
Skin
incision sites:
Ventral
thoracic, over the right clavicle, approximately 1.5 cm; Dorsal
thoracic, between the scapulae, approximately 5 mm
Venotomy
site: Right jugular
vein, immediately above the clavicle.
Intravascular
catheter tip location: Right atrium
of the heart. Location can be
determined indirectly by ease of
blood sampling or directly by
necroptic determination of catheter tip location.
Catheter
fill/lock solution: Heparinized
glycerol (Burr’s solution) or heparinized 50% dextrose solution.
Skin
incision closure: 9mm Autoclips̉.
All surgical procedures, and
experimental manipulations, should be conducted with approved protocols by
trained personnel with the appropriate veterinary guidance. Please refer
to the Guide for the Care and Use of Laboratory Animals, National
Academy of Science, 1996.

Rat Vascular Catheters
 |
Catheters consist of a continuous length of MRE037 or RPT037
with RenaSilâ suture anchors.
|
|
|
Catheters are accessed with Cat #
N-23 catheter needle and sealed with Cat # 23-PP catheter
plug. |
|
|
No adhesives; suture anchors grip
the catheter tubing without constricting the catheter lumen
and are movable. |

To
insure optimum performance: |
|
|
Always use
sterile catheter materials (cold or gas sterilization only),
injection solutions and instruments.
|
|
|
The final
step of catheter implantation or use should be advancement
of the stainless pin a few millimeters into the port in
order to displace trace amounts of blood from the catheter
tip. |
