Publication number: 20240135267Abstract: A privacy enabled system for managing clinical study participant travel has a database (stores data: clinical study, participant, clinical site and trip data sets) and a graphical user interface that has a Travel Planning Interface and is in data communication with an input device and the database. The data sets include a Study Travel Policy, a Study Visit Schedule (appointment procedure, appointment schedule), a traveler profile, traveler personal data (traveler contact information), a site appointment location associated with the appointment procedure, and site contact information. The travel planning interface receives the trip data set (trip segment data) from the database and the input device. The travel planning interface transmits the trip segment data to and receives booked travel data from a travel booking module, generates an itinerary that has booked travel and trip segment data, and transmits the itinerary according to the traveler contact information and the site contact information.Type: ApplicationFiled: March 21, 2022Publication date: April 25, 2024Inventors: SCOTT GRAY, WILLIAM WING, TREVOR SMITH, BRENT SNYDER, DONNA BRUMBACK

Publication number: 20230338728Abstract: Systems and methods for generating blood flow with a blood pump including a membrane and an encapsulated actuator are described. The pump may be implantable and may include a stator assembly, an electromagnetic assembly supported by the stator assembly, a magnetic assembly, one or more springs attached to the stator and the magnetic assembly, and encapsulation portions that connect the magnetic assembly to the stator assembly. The magnetic assembly may further be coupled to a membrane assembly including a flexible membrane. The electromagnetic assembly may be selectively activated to cause the magnetic assembly to reciprocate, thereby causing the membrane assembly to reciprocate and inducing wavelike undulations in the flexible membrane to pump blood from an inlet to an outlet of the pump. The encapsulation portions may prevent blood from interacting with an interior moving portion of the pump thereby reducing the risk of hemolysis.Type: ApplicationFiled: April 24, 2023Publication date: October 26, 2023Applicant: CorWave SAInventors: Pierre-Yves QUELENN, Carl N. BOTTERBUSCH, Trevor SNYDER, Francois CORNAT, Francesca CONDEMI, Petrus LE BLANC, Antoine Olivé

Patent number: 11309662Abstract: An electrical connector includes a plug that mates with a receptacle. In a medical application, the plug is connected to electrical leads that pass through a patient's skin to an implanted medical device in the patient's body, while the receptacle is connected to external medical equipment. All electrical contacts in the plug are on internal portions. The receptacle includes annular contacts that contact the internal electrical contacts on the plug when the plug and receptacle are properly mated. The receptacle includes a plurality of annular electrical contacts that have a first diameter and are separated by a plurality of annular insulators having a second diameter smaller than the first diameter.Type: GrantFiled: September 30, 2020Date of Patent: April 19, 2022Assignee: VADovations, Inc.Inventors: J.

Patent number: 10886663Abstract: An electrical connector includes a plug that mates with a receptacle. In a medical application, the plug is connected to electrical leads that pass through a patient's skin to an implanted medical device in the patient's body, while the receptacle is connected to external medical equipment. The plug is small in diameter so the size of the opening in the patient's skin can be minimized. All electrical contacts in the plug are on internal portions. The receptacle includes annular contacts that contact the internal electrical contacts on the plug when the plug and receptacle are properly mated. When the plug is plugged into the receptacle, spring-loaded retention arms in the receptacle lock into place on the plug, retaining the plug in the receptacle.Type: GrantFiled: June 30, 2020Date of Patent: January 5, 2021Assignee: VADovations, Inc.Inventors: J.

Publication number: 20150030664Abstract: The present application is drawn to a synthetic, polymer hydrogel-based material, which is able to actively induce the body's natural hemostatic coagulation process in blood or acellular plasma. The present invention provides the development of a primary amine containing polymer hydrogel capable of inducing blood coagulation and delivering therapeutics for hemostatic or wound care applications, and a method of forming such a primary amine containing polymer hydrogel capable of inducing the blood coagulation process. The primary amine containing polymer hydrogel is able to achieve the same end result as biological-based hemostatics, without the innate risk of disease transmission or immunological response, and at a fraction of the price. Furthermore, due to its inherent hydrogel-based design the material has the capability of arresting blood loss while simultaneously delivering therapeutics in a controlled manner, potentially revolutionizing the way in which wounds are treated.Type: ApplicationFiled: October 3, 2014Publication date: January 29, 2015Applicants: UNIVERSITY OF MARYLAND, BALTIMORE, UNIVERSITY OF MARYLAND AT COLLEGE PARKInventors: Brendan J.
