Publication number: 20140276615Abstract: The invention is a delivery catheter, e.g., a guide catheter, having an imaging element in proximity to the distal end of the catheter. Catheters of the invention are able to placement of the catheter in proximity to an ostium, thereby increasing the efficiency of contrast delivery while reducing the risk of ischemia due to blocked blood supply. The invention additionally assists in maintaining catheter position during delivery of a fluid from the catheter, resulting in better performance with less fluid. For example, a catheter of the invention can be used to produce improved fluoroscopic images with less overall contrast. This improvement reduces the risk of an allergic reaction to the contrast while decreasing the length of time for a procedure, i.e., because of a need to re-contrast.Type: ApplicationFiled: March 13, 2014Publication date: September 18, 2014Applicant: VOLCANO CORPORATIONInventor: Gil Laroya

Publication number: 20140155867Abstract: An intravenous infusion system that shows infusion flow rate, volume of medication infused, and alarming during malfunction. User intervention to adjust flow rates deviation is possible, using the data already stored in the system prior to the onset of making the adjustment. The system detects flow rate by measuring temperature dynamics in a section of the fluid path, unlike other systems that measures the electromechanical output of the pumping source if the counting of drops is not possible. This fundamental difference allows the invention to be used in any system that has a pumping source that provides a continuous fluid path as it measures actual flow of fluid in a segment of the fluid path, independent of pumping mechanism design.Type: ApplicationFiled: April 10, 2012Publication date: June 5, 2014Inventor: Freddie Eng Hwee Lee

Publication number: 20140148793Abstract: A medical device including a shaft having an elongated inner member and an elongated tubular reinforcing member disposed over at least a portion of the inner member. In some embodiments, at least a portion of the outer surface of the inner member is spaced from the inner surface of the reinforcing member, defining a space substantially free of any other structures of the device. In some embodiments, the shaft can include a tip structure disposed on a distal portion of the inner member. In some such embodiments, the reinforcing member has a distal end, and the tip structure is disposed on the distal portion of the inner member adjacent the distal end of the reinforcing member. Additionally, in some embodiments, the reinforcing member can include a plurality of apertures defined therein, for example, to enhance the flexibility or other such characteristics of all or portions of the reinforcing member.Type: ApplicationFiled: January 28, 2014Publication date: May 29, 2014Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: STEPHEN A.

Patent number: 8735491Abstract: An essentially halogen-free, plasticizer-free thermoplastic elastomer compound is disclosed. The compound has from 10-80 weight percent of a hydrogenated styrene butadiene copolymer having a styrene content of less than 20 weight percent; from 20-90 weight percent of a polyolefin; and less than about 3 weight percent of antioxidant. The compound is capable of being solvent bonded or welded to another thermoplastic material using cyclohexanone alone or with methyl ethyl ketone. The compound is especially useful as medical tubing connected to other parts of medical equipment. The bond strength of the compound to the other thermoplastic material is properly determined only after multiple days of bonding.Type: GrantFiled: December 1, 2009Date of Patent: May 27, 2014Assignee: PolyOne CorporationInventors: Sehyun Kim, Wayne Thornton

Patent number: 8728056Abstract: A docking station for maintaining sterilization of temporarily disconnected male medical line connectors. The docking station has a plurality of docking bays, each of which retain an ampule therein containing a sterilization fluid and has an access mouth exteriorly exposed when the ampule is secured in its respective bay. The mouth of the ampule is provided with a female medical line connection for temporarily receiving and securing one of the male medical line connector temporarily disconnected from a patient. A tubular tip and a concentric connection collar of the one of the male medical line connector is thereby immersed in the sterilization fluid for sterilization while docked. Each of the ampules is secured against rotation in a clockwise direction in their respective docking bay to facilitate threadable connection of one of the male medical line connector.Type: GrantFiled: November 6, 2009Date of Patent: May 20, 2014Assignee: PSI MedicaL Catheter Care, LLCInventors: Anthony J. Colantonio, Menno D. Jager

Publication number: 20140135703Abstract: A catheter system including an insertion device and a catheter device. The insertion device includes a housing, a latch, a needle for insertion into a patient; and a spring. The catheter device includes a housing comprising a chamber, and a seal disposed in said chamber. The seal is configured to reseal when the needle is withdrawn from the seal such that blood is sealed in the chamber. The spring relaxes and thereby retracts the needle entirely into the housing of the insertion device when the latch decouples from the catheter device.Type: ApplicationFiled: November 9, 2012Publication date: May 15, 2014Applicant: CAREFUSION 303, INC.Inventors: Jonathan YEH, George MANSOUR, Chris ZOLLINGER
