International Classification:

A61M 100

US Classification:

604151, 4174772

Abstract:

A medical irrigation pump and pump system utilize a permanent non-sterile drive motor capable of operating disposable sterile single use pump units each of which is specifically designed for a particular medical procedure. The pump units have housing which are adapted to be interchangeable within the permanent controller system. Only the sterilized and disposable pump units come into contact with the fluid pathway during pumping. A pattern of bumps on each pump unit is unique for the medical procedure for which the pump unit was designed. The pattern of bumps engages switches on the controller, enabling the controller to identify what type of pump unit has been installed. After automatically identifying the type of pump unit and the intended medical procedure, the controller automatically selects a default motor speed that will provide an appropriate fluid pressure for that particular procedure. Buttons on a control panel also enable the user to manually adjust the pressure delivered by the pump. The orientation of the pump unit during the loading procedure allows easy purging of all air from the pump unit before the pump is started.

International Classification:

A61M 31/00

US Classification:

604510

Abstract:

Methods and apparatus are disclosed for inserting flexible, multi-lumen catheters into blood vessels, and in particular, for inserting flexible, split-tip catheters into blood vessels. The invention accomplishes these objects by temporarily stiffening each catheter lumen and tip independently through use of intra-catheter stiffener elements disposed within the catheter lumens. This provides means for advancing the catheter/stiffeners assembly through a subcutaneous tunnel, and over a plurality of guidewires until a distal tip of the catheter is at a desired position within the vessel. The intra-catheter stiffener elements are sufficiently stiffening to allow advancing the catheter over guidewires, but sufficiently flexible to allow bending and looping of the catheter for proper placement within the vessel.

Abstract:

A medical kit, including a split-tip catheter, a first intra-catheter stiffener element, a second intra-catheter stiffener element, a first guidewire, and a second guidewire. The split-tip catheter includes a first lumen in fluid communication with a first distal opening and a second lumen in fluid communication with a second distal opening with the first distal opening proximal to the second distal opening. The first intra-catheter stiffener element is designed for disposition in the first lumen, and the second intra-catheter stiffener element is designed for disposition in the second lumen. The first intra-catheter stiffener element includes a first guidewire lumen, and the second intra-catheter stiffener element includes a second guidewire lumen.
