Patent number: 7547302Abstract: 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: August 31, 2005Date of Patent: June 16, 2009Assignee: I-FLOW CorporationInventors: James Dal Porto, Jose Castillo Deniega, Roger Massengale, Lois Rake, legal representative, Kevin Forrest, Mark Siminuk, Kenneth W.

Patent number: 7527609Abstract: The present invention provides a catheter for the delivery of fluid medication across an anatomical region. In accordance with some embodiments, the 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. In accordance with other embodiments, the catheter includes an elongated “weeping” tubular coil spring attached to an end of, or enclosed within, a tube. Fluid within the spring and greater than or equal to a threshold pressure advantageously flows radially outward between the spring coils. Advantageously, the fluid is dispensed substantially uniformly throughout a length of the spring. In accordance with other embodiments, the catheter includes a tube having a plurality of exit holes in a side wall of the tube.Type: GrantFiled: April 8, 2002Date of Patent: May 5, 2009Assignee: I-Flow CorporationInventors: Jose Castillo Deniega, Roger Massengale, Kenneth W.

Patent number: 7510550Abstract: 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: May 12, 2003Date of Patent: March 31, 2009Assignee: I-Flow CorporationInventors: Jose Castillo Deniega, Roger Massengale, Kenneth W.

Publication number: 20090076478Abstract: 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: ApplicationFiled: November 17, 2008Publication date: March 19, 2009Applicant: I-FLOW CorporationInventors: James Dal Porto, Jose Castillo Deniega, Roger Massengale, Kenneth W.

Patent number: 7392140Abstract: Methods for the diagnosis and evaluation of stroke and stroke sub-type employ a variety of bio-markers including cellular fibronectin (c-Fn) assembled as a panel for stoke diagnosis and evaluation. Methods are disclosed for selecting markers and correlating their combined levels with a clinical outcome of interest. In various aspects the methods permit early detection and differentiation of stroke subtypes, determination of the prognosis of a patient presenting stroke symptoms, and identification of a patient at risk for early hematoma growth and/or malignant massive cerebral artery infarction. The disclosed methods provide rapid, sensitive and specific assays to greatly increase the number of patients that can receive beneficial stroke treatment and therapy, and to reduce the human and economic costs associated with incorrect stroke diagnosis.Type: GrantFiled: February 1, 2006Date of Patent: June 24, 2008Assignee: Prediction Sciences, LLCInventors: Joaquín Serena, Antoni Dāvalos, Mar Castellanos, José Castillo, Cornelius Allen Diamond

Patent number: 7230781Abstract: An information storage system has structure with a head that can effect information transfers with respect to a storage medium. According to one feature, a control portion monitors a characteristic of information read from the storage medium, and can take action to reduce the likelihood of non-recoverable errors based on the characteristic. According to a different feature, the control portion moves the head to a position adjacent a portion of a surface on the storage medium, waits while moving the head relative to the surface, and then moves the head to another position adjacent a different portion of the surface. According to another feature, the control portion calculates a distance of the head from the surface based on information read from the surface, and determines based on this distance whether the head or the storage medium may fail to satisfy a criteria.Type: GrantFiled: November 20, 2003Date of Patent: June 12, 2007Assignee: Iomega CorporationInventors: Yiping Ma, José Castillo, David L.

Patent number: 6902385Abstract: A melt distribution block for feeding melt through an extrusion die to an extrusion passage. The melt distribution block has a generally annular body with inner, outer, front and rear faces. The front and rear faces include a series of flow divider channels therein extending generally radially inwardly from an inlet and terminating in a plurality of feed spirals. The feed spirals curve radially inwardly from the flow divider channels to encircle the inner face and narrow toward a radially inwardly disposed end. The feed spirals on the front and rear spaces curve in respectively opposite directions. An inlet port extends into the outer face and fluidly communicates with the inlet of the flow divider channels. A melt distribution die includes an axially stacked array of melt distribution blocks interspersed with separator blocks extending radially about a centrally disposed mandrel to define an extrusion and passage therebetween.Type: GrantFiled: January 31, 2002Date of Patent: June 7, 2005Inventor: Rafael José Castillo

Publication number: 20040150915Abstract: A head includes a bearing surface portion disposed between two transition surface portions which progressively diverge away from a plane containing the bearing surface portion. The bearing surface portion and transition surface portions collectively form a generally continuous surface which is substantially free of abrupt discontinuities in a head travel direction. A method of making the head involves use of a gray-scale mask to pattern a photoresist on a substrate, after which the photoresist is developed and the substrate is etched through the photoresist in order to create on the substrate a three-dimensional surface which includes the bearing surface portion and transition surface portions.Type: ApplicationFiled: February 5, 2003Publication date: August 5, 2004Inventors: Fred C.
