SurgiVet Tomcat Urethral Catheters. This Silicone catheter can be used for long term upon removal of the Slippery Sam Catheter. It allows drainage or administration of fluids. The silicone allows it to be left in long term because there is minimal irritation to the urethral mucosa or bladder wall. It is available in closed end (TM35) or open endhole design (TM35OE). The open ended design is most commonly used if there are stones or paste present in the bladder. A wire guide style to aid in introduction is also provided with the catheter because of the softness of the silicone. Low profile silicone hub with suture holes will aid in preventing the catheter being removed prematurely by the cat. The hub will accept a standard luer lock syringe, an IV bag for closed collection or a Little Herbert Adaptor. Reusable and autoclavable. Sterile.
