Publication number: 20230390528Abstract: A catheter stabilization and interrogation device includes a flexible substrate with a proximal portion, a distal portion spaced from the proximal portion, and an intermediate portion located, at least partially, between the proximal portion and the distal portion. The intermediate portion conforms to a patients body, and a bottom surface of the substrate has an adhesive to secure the device to a patient. A stabilizer secured to the proximal portion stabilizes the catheter relative to the patients vasculature and a receptacle located within and/or upon the distal portion receives an interacting element and positions the interacting element relative to the catheter. A monitoring device, constructed within at least the intermediate portion, monitors at least one event within the patient.Type: ApplicationFiled: October 28, 2020Publication date: December 7, 2023Applicant: NP Medical Inc.Inventors: Todd Chelak, John Damarati

Publication number: 20230144638Abstract: A low profile catheter system includes a catheter hub with proximal, distal, and intermediate portions, a stabilization surface located on an underside, and a receptacle located within a top surface. A substantially linear flow path extends from an opening at the distal portion to an inlet located within the intermediate portion and allows fluid to flow between the distal and intermediate portions. The inlet of the flow path is located between the proximal and distal portions. A base connector has a fluid path extending through at least a portion of the base connector and between a first opening located nearer a first end and a second opening. The fluid path is fluidly connected to the inlet of the flow path and a second end of the base connector is retained within the receptacle by the proximal portion when the base connector is received by the receptacle.Type: ApplicationFiled: January 3, 2023Publication date: May 11, 2023Inventors: Todd Chelak, Ian Kimball, Luis Maseda, Jonathan Gabel

Patent number: 10835730Abstract: A medical valve has a housing with an inlet housing and an outlet housing. The interior of the inlet housing and/or the outlet housing has a contact surface. A resilient element sits within the housing and controls fluid flow through the inlet. The resilient element has a proximal portion with a normally closed aperture configured to open when actuated by a medical device. The resilient element also has a distal portion adjacent to the outlet, and a central portion between the proximal portion and the distal portion. The central portion has a wall that defines a fluid chamber in the open mode and in the closed mode. The wall has at least one projection extending radially outward. The projection maintains compressive contact with the contact surface of the housing and applies an inwardly compressive force on the resilient element, increasing the wall stiffness.Type: GrantFiled: February 28, 2018Date of Patent: November 17, 2020Assignee: NP MEDICAL INC.Inventors: Todd Chelak, Nicholas Illsley, Nicholas Dennis

Patent number: 10376684Abstract: A medical port includes a hub having a body forming a hub chamber for containing a fluid, and a proximal opening to the hub chamber for receiving a medical implement. The port also has a valve member, a first radial fluid channel, and a second radial fluid channel. The valve member is located within the hub chamber, has a radial portion, and closes the proximal opening when the medical port is in a closed mode. The first and second radial fluid channels are in fluid communication with the hub chamber when the medical port is in the closed mode. The radial portion of the valve member restricts fluid communication between the first radial fluid channel and the hub chamber when the medical port is in an open mode.Type: GrantFiled: December 18, 2014Date of Patent: August 13, 2019Assignee: NP MEDICAL INC.Inventors: Todd Chelak, Ian Kimball
