Abstract: A system for heating and insulating contrast media is disclosed herein. A thermal insulating cover sized to cover at least a portion of a contrast media container is provided with a heating element. A temperature sensor measures the temperature of the contrast media and communicates this temperature to a temperature controller, which controls the heating element in order to maintain the contrast media near a predetermined temperature. Temperature data is transmitted to a computer system by a data communicator.

Abstract: An extravascular system for accessing the vasculature of a patient may include a catheter assembly and an internal construct within the catheter assembly. At least one fluid flow space may exist between the internal construct and the catheter assembly.

Abstract: A catheter having a catheter body with a lumen and a distal lumen opening. The catheter's lumen extends through the catheter body along a longitudinal axis of the catheter body. A hole is formed through a wall of a distal portion of the catheter body. A portion of the proximal surface of the hole is inclined at an acute angle with respect to the longitudinal axis of the catheter body. The acute angle of the proximal hole surface opens proximally with respect to the catheter body.

Abstract: A peripheral catheter having a catheter tip diffuser for reducing an exit velocity of an infusant within the catheter. Pluralities of diffusion side holes are provided on the tip portion of the catheter. Some examples further include pluralities of annularly arranged, staggered diffusion holes provided on the tip portion of an intravenous catheter to streamline infusant issued from the diffusion holes. An inner surface of each diffusion hole is further angled relative to the inner surface of the catheter lumen such that an infusant within the lumen exits the catheter though the diffusion holes at an angle less than 90°.

Abstract: A medical device includes a vascular access device with an access port having a septum and a slit. The slit is formed on the inner surface of the body of the septum where the access port receives an access device that is separate from the vascular access device through the slit of the septum. A pivoting member in communication with the access port pivots when the port is accessed by an access device. The medical device may be used to control the volume displacement of a chamber within the medical device by decreasing the volume of the chamber by inserting a substance having a mass into the chamber, pivoting a structure associated with the chamber, and increasing the volume of the chamber simultaneously and commensurately with the mass of the substance inserted into the chamber.

Abstract: An auto-occlusion safety device is provided for use in preventing rupture of infusion components during rapid infusion procedures. An occlusion valve is disclosed having a threshold pressure that is less than a rupture tolerance of the infusion system components. As the fluid pressure of the infusion system increases beyond the threshold pressure of the occlusion valve, the occlusion valve is automatically activated thereby occluding fluid flow upstream from a vulnerable infusion component. An accumulator is further disclosed for use in combination with the safety device to compensate for time delays in full activation of the occlusion valve.

Abstract: A medical device may include a vascular access device with an access port which may include a septum and a slit. The slit may be formed on the inner surface of the body of the septum and the access port may be capable of receiving a separate access device through the slit of the septum. The medical device may also include a flexible member which expands to create an additional volume within the access port when the port is accessed by the access device. A method of controlling volume displacement a chamber of a medical device may include decreasing the volume of a chamber of an extravascular system by inserting a substance having a mass into the chamber and/or increasing the volume of the chamber simultaneously and commensurately with the mass of the substance inserted into the chamber.

Abstract: A fitting is disclosed that adapts the wand of an oral irrigation device for use in nasal irrigation. An oral irrigation wand is inserted into a fitting, which is then placed in the nostril. The fitting is compatible with the wands of many brands and models of oral irrigation devices. The fitting dampens the change in amplitude of the pulsations from pulsating-type irrigation devices, resulting in a safer, more pleasant nasal irrigation experience. The fitting is removable and protects the user's nostril from contact with the wand and allows the wand to be used for both nasal and oral irrigation. The fitting allows for comfortable insertion into a nostril, providing a complete seal with both the nose and the nasal irrigation device, to promote both a tidy and effective nasal irrigation experiences. The fitting is sturdy, simple and easy to manufacture, providing for long life and performing well even with long, repetitive use.
