20090287167 | Y-PORT DEVICE ELIMINATING ABBERANT CURRENTS - A y-port device including a valve positioned proximally to the fluid channel thereby eliminating aberrant currents and dead space within the y-port device. The valve is a septum and penetrable by a probe. The valve is positioned such that the external end may be cleaned and/or sanitized prior to penetration by a probe and the internal end abuts the fluid channel of the device such that dead space is eliminated between the flow path and the internal end of the valve. The y-port device ensures that an entire infused bolus is flushed from the interior of the y-port and into the desired vascular system. | 11-19-2009 |
20100057020 | Apparatus and method for treatment of bifurcation lesions - Each arterial bifurcation lesion has a fingerprint-like pattern related to varying amounts of plaque and degree of obstruction in the main vessel proximal to, within the bifurcation itself, and the distal limbs of the main branch and side branch(es) and related to the angle of the bifurcation. A new device and with it a new technique is described to optimize treatment of bifurcation (and trifurcation) lesions. The invention and related method use a catheter capable of delivering two or more guide wires exiting at the distal end of the catheter allowing treatment of lesions more safely and efficaciously. Safety is increased by allowing both guide wires to remain in place throughout the entire procedure. Efficacy is increased, particularly in the long-term, by providing a result that maximizes vessel coverage and normal flow dynamics in the entire bifurcation area. Contemplated is the use not only of multiple guide wires but also modified balloon with a tapered design to optimize flow dynamics at the bifurcation in the final result. | 03-04-2010 |
20100280463 | VALVE BODY, PROCESS FOR PRODUCING VALVE BODY, AND MEDICAL INSTRUMENT INCLUDING THE VALVE BODY - A valve body, e.g. a valve body adapted to be disposed in a connector to be connected to a catheter, has an opening/closing part which opens upon inserting a member into the opening/closing part and which closes upon withdrawing the member from the opening/closing part. The valve body includes a main body part made of a silicone rubber and a surface layer disposed on a surface of the main body part. This surface layer serves as a sliding surface which, when a guide wire has been inserted into the opening/closing part, slides on the guide wire. The surface layer is constituted mainly of silicon oxide and hence improves the sliding properties of the guide wire. Thus, the valve body is reduced in the resistance of sliding on the guide wire. | 11-04-2010 |

The catheter hub defines a reduced profile to facilitate passage of the catheter hub through a surgical tunnel. The clamp includes first and second clamp sections and defines a longitudinal clamp axis. The clamp has a longitudinal opening for passage of the extension tube and a movable member adapted to move from a first position to a second position to substantially close the internal lumen. The first and second clamp sections are separable to facilitate transverse positioning of the clamp sections about the extension tube. | 05-08-2014 |
20140200524 | Curved Catheter and Methods for Making Same - A pre-curved catheter tube of a catheter assembly or other elongate medical device and methods for forming such a device using a heating procedure is disclosed. Pre-curving of the catheter tube is desirable to impart to the catheter assembly a desired positional configuration when the catheter assembly is inserted into a patient. The heating procedure may include heat sterilization procedures commonly used to sterilize medical devices prior to use. In one embodiment, therefore, a catheter assembly is disclosed, comprising an elongate catheter tube defining at least one lumen, and a tube constraint. The tube constraint is included with the catheter assembly and is configured to temporarily constrain the catheter tube in a curved configuration during a heating procedure of the catheter assembly so as to permanently form the catheter tube in the curved configuration after the heating procedure is complete and the catheter tube is released from the tube constraint. | 07-17-2014 |
