Publication number: 20190321072Abstract: Apparatuses and methods can be used to guide placement of needles within the body. For example, this document describes apparatuses that measure impedance and/or force as a needle is passed through tissue to inform user of which anatomical space they are in. Low-cost portable bedside electro-physical apparatuses and methods for needle guidance and confirmation of successful placement in portions of the human body such as vessels and thecal sac are described herein.Type: ApplicationFiled: April 23, 2019Publication date: October 24, 2019Inventors: Kalpathi L. Venkatachalam, Vivek Gupta, Prasanna Vibhute, Alexander Bills, Lucas Muller, Dev Mandavia, Cassidy Wang, Marci Medford

Patent number: 9585708Abstract: Some embodiments of a medical instrument can be configured to reduce the formation of coagulum by delivering a negative charge bias to conductive surfaces that interface with blood or bodily tissue during a medical procedure. The application of the negative charge at the instrument-blood interface can reduce the fibrinogen deposition and the formation of coagulum because fibrinogen molecules in general are negatively charged at neutral pH levels. In addition, some embodiments of the instrument may be configured to irrigate the instrument-blood interface with RGD/ClfA peptides, a bicarbonate solution (or other high pH solution), or both to further repel the fibrinogen and thereby inhibit the formation of coagulum. Accordingly, some embodiments of the medical instrument can substantially reduce the risks of thromboembolism during particular medical procedures.Type: GrantFiled: February 3, 2016Date of Patent: March 7, 2017Assignee: Mayo Foundation for Medical Education and ResearchInventors: Samuel J. Asirvatham, Arshad Jahangir, Bernard B. C. Lim, Kalpathi L. Venkatachalam

Publication number: 20160151105Abstract: Some embodiments of a medical instrument can be configured to reduce the formation of coagulum by delivering a negative charge bias to conductive surfaces that interface with blood or bodily tissue during a medical procedure. The application of the negative charge at the instrument-blood interface can reduce the fibrinogen deposition and the formation of coagulum because fibrinogen molecules in general are negatively charged at neutral pH levels. In addition, some embodiments of the instrument may be configured to irrigate the instrument-blood interface with RGD/ClfA peptides, a bicarbonate solution (or other high pH solution), or both to further repel the fibrinogen and thereby inhibit the formation of coagulum.
