New Bump tubing Catheters for Rodent Vascular Applications

What is Bump tubing (BTing™)? 

Bump tubing is a continuous length of Tecoflex® polyurethane tubing with a tapered transitional section resulting in catheter tubing with the intravascular tubing section ID/OD of 0.012”/0.025” and an extra-vascular tubing section ID/OD of 0.023”/0.037”.

Rat Thoracic Catheter

Standard R-JVC / R-CAC Catheter

Rat Thoracic Jugular Vein Catheter                              
Jugular Vein Catheterization How-2

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 AutoclipsÒ.

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 Thoracic Carotid Artery Catheter                                                  
Carotid Artery Catheterization How-2

Specifications: Port Length:  20-25 mm; Catheter Body Length:  55-65 mm; Intravascular Tippet Length: 26 mm 

Intravascular Tippet Length:  26 mm    

Procedural Overview:  Carotid Artery Catheterization
 

Skin incision sites:  Ventral thoracic, over the trachea, approximately 1.5 cm; Dorsal thoracic, between the scapulae, approximately 5 mm.

Arteriotomy site:  Left carotid artery, immediately below the carotid bifurcation.   Care must be taken to avoid damage of nerve fibers that run along the surface of the carotid artery.  Nerve damage is often demonstrated by left ptosis or drooping of the eyelid.

Intravascular catheter tip location:  Descending aortic arch.

Catheter fill/lock solution:  Heparinized glycerol (Burr’s solution) or heparinized 50% dextrose solution.

Skin incision closure:  9mm AutoclipsÒ.

Trained personnel with the appropriate veterinary guidance should conduct all surgical procedures, and experimental manipulations, with approved protocols. Please refer to the Guide for the Care and Use of Laboratory Animals, National Academy of Science, 1996.

New Polyurethane (Micro-Renathane® and RenaPulse®)
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.
	Catheter tip rounding available for MRE037 catheter fabrications

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.
