20080243074 | Catheter malfunction determinations using physiologic pressure - Methods and systems for determining whether an implanted catheter used to deliver fluids to a selected internal delivery site is malfunctioning. The malfunctions may include that the infusion section of the catheter is not located at or has migrated away from the selected internal delivery site, is leaking, is blocked, etc. The determination is made by analyzing the pressure modulation of fluid within the catheter and determining whether the pressure of the fluid in the catheter is modulated by physiologic pressure changes experienced at the selected internal delivery site. The physiologic pressure modulations at the selected internal delivery site may be caused by, e.g., cardiac activity, respiration, changes in patient's posture, etc. | 10-02-2008 |
20080243075 | Medical Device with Retractable Needle - A tamperproof retractable non-reusable syringe has a one piece hollow outer body with a barrel for a slidable plunger, a transition zone and a smaller diameter nose portion.

The plunger has an opening with a dislodgable stopper for receiving parts of the retraction mechanism. The stopper and the head of the needle holder are of significantly reduced diameter from the injection fluid chamber to resist blowing out prematurely. In one embodiment the head of the needle holder is surrounded by a separable retainer member which is slidingly removed by contact with the tip of the plunger after the stopper is mostly or fully removed to avoid cumulation of force required for retraction after the injection. In a second embodiment the head of the needle holder is clamped and held by constricting forces imposed by stress on the outer body induced by interference fit. Release occurs by slight expansion on the barrel by contact of the plunger tip with a small internal ramp in the outer barrel. Both embodiments have a plunger cap configured to enter an opening in the outer body to provide an additional tamperproof feature. The retraction cavity is provided with venting structures to assure that all uninjected fluid is retained within the syringe body. | 10-02-2008 |
