Publication number: 20160361529Abstract: The present invention relates to subcutaneously implanted graft-port systems, devices and methods for establishing access to the vascular system of a patient requiring multiple blood treatments over an extended period of time. The systems, devices and methods disclosed herein reduce miscannulation, promote intra-session hemostasis, and decrease the incidence of bacteremia and sepsis among other improvements and advantages. The devices include a port with a flattened plateau-like surface for receiving an access tube. The flat surface may include a tactile or visual guide to assist with placement of the access tube into the tapered seat. Optional valve mechanisms reduce the size and form factor of the implantable graft-port device and seals the conduit of the port closed to physiologic pressures until the valve is opened upon percutaneous insertion of the access tube. The access tube does not pass into the conduit.Type: ApplicationFiled: June 10, 2016Publication date: December 15, 2016Inventor: Charles David Finch, JR.

Publication number: 20110213025Abstract: Methods, compositions and kits are disclosed for infusing a hydrophobic catheter lock solution into an indwelling catheter. The combination of a tocopherol compound and at least one saturated mid-chain fatty acid provides a broad spectrum antimicrobial solution with optimal viscosity for effectively locking a catheter. The lock can effectively reduce or eliminate the risk of infection and prevents tainting the catheter, particularly clotting and thrombus in intravascular and extravascular catheters. The potential for this discovery is for maintaining or reestablishing the viability of an intravascular or extravascular catheter, as well as topical formulations for promoting healing.Type: ApplicationFiled: August 10, 2010Publication date: September 1, 2011Applicant: ProviFlo, LLCInventor: Charles David Finch, JR.

Publication number: 20070252759Abstract: A compact system can use modular components to enhance the isolation or quality of signals that an antenna array produces. The system can comprise an array of input coupler modules and an array of output coupler modules respectively on the input and output sides of a signal routing device. Each input coupler module can receive a signal from a specific element in the antenna array and can divide or split that received signal into a multiple signal components, such as seven. The signal routing device can route each of those signal components to a different output coupler module in the array of output coupler modules. Thus, each output coupler module can receive and combine multiple signal components, such as seven, from different input coupler modules. The signal routing device can include a readily manufacturable phase trimming section to compensate for phase mismatches.Type: ApplicationFiled: May 1, 2006Publication date: November 1, 2007Applicant: EMS Technologies, Inc.Inventors: Theresa Brunasso, John Voss, David Finch, Wyman Williams, Christopher Burton

Patent number: 7004924Abstract: Methods, systems, and kits for extracorporeally circulating and processing blood are described. The systems include a pump, a processing unit, and blood drawn return lines for accessing a patient's vasculature. Blood flow through the return line is measured and pump speed controlled to maintain a desired blood flow rate. Alarm conditions can be initiated when expected pump performance differs from that needed to maintain the control point flow rate. By using a ultrasonic flow detector, gas bubbles in the blood flow can be detected.Type: GrantFiled: October 19, 1998Date of Patent: February 28, 2006Assignee: NxStage Medical, Inc.Inventors: James M.

Patent number: 6830553Abstract: Hemofiltration systems and methods circulate blood from an individual through a hemofilter to remove waste and to return blood and replacement fluid to the individual after removal of waste. The systems and methods maintain sterile extracorporeal processing conditions during and between therapy sessions. For example, the systems and methods include a waste discharge path in the extracorporeal circuit to convey waste fluid to a waste receiving unit. The waste discharge path includes an air break. The air break prevents back flow of waste contaminants into the extracorporeal circuit from the waste receiving unit. As another example, the systems and methods include a replacement fluid path in the extracorporeal circuit to convey replacement fluid from a source to the extracorporeal circuit. The replacement fluid path includes a sterilizing filter to avoid contamination of the extracorporeal circuit.Type: GrantFiled: February 25, 2000Date of Patent: December 14, 2004Assignee: NxStage Medical, Inc.Inventors: Jeffrey H. Burbank, James M. Brugger, Dennis M. Treu, C. David Finch, Jr.

Patent number: 6582385Abstract: A hemofiltration system is provided in which ultrafiltrate is purified by reverse osmosis for reinfusion. Non-sterile infusate concentrate is dialyzed into the purified ultrafiltrate and combined with cleared blood which is returned to the patient. In another system, a hemofilter is used to sterilize essentially pure, non-sterile water for dilution of sterile infusate concentrate, then the hemofilter is used to filter blood, the infusate concentrate being combined with cleared blood for return to the patient.Type: GrantFiled: February 19, 1998Date of Patent: June 24, 2003Assignee: NStage Medical, Inc.Inventors: Jeffrey H Burbank, C David Finch, James M Brugger

Publication number: 20020147423Abstract: A flow management system comprising a first panel having a fluid pathway and a second panel having a fluid pathway for passing a second fluid. The fluid pathway of the first panel passes a first fluid. The first panel includes a first compartment to receive a volume of the first fluid. The second panel includes a second compartment to receive a volume of the second fluid. The first and second panels are aligned so that the first compartment overlays the second compartment. The flow management system may be placed within a gap defined by a first surface and a second surface. The first and second compartments are disposed within the gap so that the second compartment bears against the second surface as the second fluid fills the second compartment and forces the first fluid out from the first compartment as the first compartment bears against the first surface.Type: ApplicationFiled: January 7, 2002Publication date: October 10, 2002Applicant: NxStage Medical Inc.Inventors: Jeffrey H.

Patent number: 6436084Abstract: Implantable ports and other devices are disinfected by the injection of an anti-microbial agent into a region in the device or in a tissue pocket surrounding the device. In a first embodiment, the anti-microbial agent is injected through an aperture in the device to flush internal regions of the device before infusing the tissue pocket and flushing outwardly through a tissue tract leading to the device. In other embodiments, the anti-microbial agent is injected directly to a target site on the exterior of the device. Implantable devices may include special, usually hardened, target regions for receiving the sharpened end of a needle used to inject the anti-microbial agent. Kits will include devices, syringes, access devices, and instructions for disinfection according to the methods of the present invention.Type: GrantFiled: September 25, 1998Date of Patent: August 20, 2002Assignee: VASCA, Inc.Inventors: Charles David Finch, Jeffrey H.
