Patent number: 9084870Abstract: The present invention provides a catheter for the delivery of fluid medication across an anatomical region. In accordance with some embodiments, the catheter includes a tube having a plurality of exit holes in a side wall of the tube and an elongated member positioned within the tube. The exit holes combine to form a flow-restricting orifice of the catheter. Advantageously, fluid within the catheter flows through all of the exit holes, resulting in uniform distribution of fluid within an anatomical region.Type: GrantFiled: September 21, 2011Date of Patent: July 21, 2015Assignee: Avent, Inc.Inventors: Jose Castillo Deniega, Roger Massengale, Kenneth W. Rake

Patent number: 8628633Abstract: Catheters for uniform delivery of medication within an anatomical region. A catheter includes an elongated tube with a plurality of exit holes along an infusion section of the catheter, and an elongated flexible porous member residing within the tube and forming an annular space between the tube and the member. A catheter includes a tube having a plurality of exit holes in a side wall of the tube. The exit holes may combine to form a flow-restricting orifice of the catheter. A catheter includes an elongated tubular member made of a porous membrane. The porous membrane is configured so that a fluid introduced into an open end of the tubular member will flow through side walls of the tubular member at a substantially uniform rate along a length of the tubular member. A catheter includes an elongated “weeping” tubular coil spring attached to an end of, or enclosed within, a tube.Type: GrantFiled: August 3, 2009Date of Patent: January 14, 2014Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Jose Castillo Deniega, Roger Massengale, Kenneth W.

Patent number: 8343135Abstract: A catheter having features configured to provide a substantially uniform flow rate of a fluid exiting the catheter and also exhibits anti-microbial properties. The uniform flow rate features may include one or more of a flow restricting membrane or flow restricting component within an infusion section of the catheter. In other arrangements, exit holes defining the infusion section of the catheter may be configured to provide the desired uniform flow rate over the length of the infusion section. Furthermore, the catheter also includes anti-microbial properties to inhibit the growth of microbes on or within the catheter and, preferably, to inhibit microbe growth in an anatomical region surrounding the catheter. The desired anti-microbial properties may be provided by an anti-microbial layer, anti-microbial materials dispersed within the material from which components of the catheters are constructed, or a combination of anti-microbial layers and embedded anti-microbial materials.Type: GrantFiled: March 31, 2009Date of Patent: January 1, 2013Assignee: Kimberly-Clark Worldwide, Inc.Inventors: James Dal Porto, Jose Castillo Deniega, Roger Massengale, Kenneth W.

Patent number: 8048057Abstract: A catheter is provided for uniform distribution of fluid medication within an anatomical region. One embodiment of the catheter is comprised of an elongate tubular catheter body defining a lumen. A distal end of the lumen is closed and a portion of the catheter body includes a plurality of openings thereby defining an infusion section of the catheter. A tubular sheath is constructed from a porous material and is positioned over the infusion section. The tubular sheath extends at least a length of the infusion section. The tubular sheath and the catheter body are configured such that fluid within the lumen must pass through the tubular sheath to exit the catheter. In at least one embodiment, a pore size of the porous material is less than about 0.5 microns.Type: GrantFiled: March 30, 2009Date of Patent: November 1, 2011Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Jose Castillo Deniega, Roger Massengale, Kenneth W.

Patent number: 7854730Abstract: A catheter is provided for uniform distribution of fluid medication within an anatomical region. One embodiment of the catheter is compromised of an elongated, proximal tube defining a lumen and an elongated, distal tube having a closed end. The distal tube is constructed from a bio-absorbable material and also defines a lumen, which communicates with the lumen of the proximal tube. In one embodiment, at least a portion of the distal tube defines a porous side wall that permits fluid within the lumen to pass through the portion of the distal tube. In another embodiment, the proximal tube and the distal tube overlap one another and are secured to one another at the overlapping surfaces.Type: GrantFiled: November 17, 2008Date of Patent: December 21, 2010Assignee: I-Flow CorporationInventors: James Dal Porto, Jose Castillo Deniega, Roger Massengale, Kenneth W.

Patent number: 7815604Abstract: A device and method for the infusion of medicinal fluid at a controlled flow rate to a wound site or the blood stream of a patient is disclosed. A pump delivers fluid under pressure from a fluid source through a continuous and substantially constant flow path and through a supplemental bolus dose flow path. A large volume bolus dose reservoir accumulates a large quantity of fluid from the bolus dose flow path and holds the fluid under pressure. A flow regulator controls the fill rate of the large volume bolus reservoir. The large volume supplemental bolus dose is released from the bolus reservoir upon patient activation of a valve. The release rate of the bolus dose is controlled by the decompression of an elastomeric sphere or spring chamber, by the pressure gradient at the valve and/or by optional flow control tubing.Type: GrantFiled: December 29, 2005Date of Patent: October 19, 2010Assignee: I-Flow CorporationInventors: Roger Dillard Massengale, Kenneth W.

Publication number: 20080215029Abstract: Disclosed is an infusion pump and a fluid container for expelling a fluid from the fluid container to a patient. The pump comprises a housing having a chamber therein for receiving the fluid reservoir. A first wall is provided on the housing for contacting the fluid reservoir, and a second wall is movable from a first position distanced from the first wall to form the chamber therebetween, and a second position relatively closer to the first wall. Advancing the movable wall from the first position to the second position expels fluid from the collapsible reservoir. Preferably, the first and second walls are provided with non-planar complementary surface configurations for contacting the collapsible reservoir. Retraction mechanisms for retracting the movable wall from the second position to the first position, and user readable indicium of the status of the dispensation cycle are also disclosed.Type: ApplicationFiled: March 3, 2008Publication date: September 4, 2008Applicant: I-FLOW CorporationInventors: Kenneth W.
