20090209914 | Sealing arrangement for medical introducer - A sealing arrangement for a medical introducer having a distal end for introduction into a patient's blood vessel. The introducer includes a flexible sealing member having an aperture for introduction of a guide wire or other medical device therethrough. A constraining structure, such as a washer, tightly contacts and surrounds the sealing member just proximal to an enlarged diameter flange at the distal end of the sealing member. The inner diameter of the constraining member is less than the outer diameter of the flange providing a constraint on the sealing member and lessening the distortion of the sealing member normally occasioned when a device is pulled outwardly or proximally through the introducer away from the patient. When the constraining structure is a washer, the washer is easily assembled to the introducer by simply being fitted into an annular notch formed just proximal to the distal end of the sealing member. | 08-20-2009 |

The valve seal is moulded in its final form. The valve seal has at least three valves, which enhance sealing capability, and the design of the valve seal is suitable for trocars with cannulas of various diameters. | 03-25-2010 |
20100168675 | ONE PIECE LOW DRAG SEPTUM - A one-piece low drag septum is provided for preventing escape of fluid from an introducer needle during removal of such a needle from a catheter and introducer needle assembly. The septum generally includes a distal portion, a proximal portion, a cavity portion, and a longitudinal axis. The distal portion acts as a primary seal to prevent escape of blood from the catheter into the assembly and is generally positioned furthest away from the user of the apparatus and nearest the patient. The cavity portion reduces friction placed on the introducer needle. The proximal portion of the septum acts as a secondary seal to prevent escape of material from the cavity, seals the cavity, and wipes the needle as it is being withdrawn from the catheter assembly. | 07-01-2010 |
20100217195 | Needle for Bloodless IV - An intravenous catheter system having a retractable needle system and a body system is disclosed.

20150038910 | BLOOD CONTROL CATHETER VALVE EMPLOYING ACTUATOR WITH FLEXIBLE RETENTION ARMS - The present invention extends to a blood control catheter valve for use in a catheter adapter. The blood control catheter value employs an actuator for bypassing a septum to open the blood control catheter valve. The actuator includes flexible retention arms positioned on one end which retract into the body of the actuator while the end of the actuator passes through the septum, and then expand outwardly to maintain the actuator positioned within the septum. This design facilitates the manufacturing of catheter adapters (as well as blood control catheter valves and other components that attach to the catheter adapter) because the design can reduce the tolerance requirements of such components. Further, the design provides a reliable blood control catheter valve that does not require the catheter adapter to be increased in size to accommodate the valve. | 02-05-2015 |
20150080801 | CATHETER ASSEMBLY - A catheter assembly including: an inner needle having a sharp tip at a distal end thereof; an inner needle hub connected to a proximal end portion of the inner needle; a catheter through which the inner needle is inserted; a catheter hub connected to a proximal end portion of the catheter; and a protector that covers at least the tip of the inner needle when the inner needle is withdrawn. The protector includes: an inner tube that includes at least one arm that releasably engages with a proximal end of the catheter hub from an outer side of the catheter hub; and an outer tube inside which the inner tube is arranged, and which is capable of being displaced in an axial direction relative to the inner tube. The catheter assembly is configured such that, when the inner needle is withdrawn, after the tip of the inner needle has been stored in the protector, the outer tube is retracted with respect to the inner tube thereby allowing the at least one arm to be displaced outwardly, whereby engagement between the at least one arm and the catheter hub is released. | 03-19-2015 |
