The automatic detection of lumber anatomy in epidural injections for ultrasound guidance [PDF]
arXiv, 2023 The purpose of this paper is to help the anesthesiologist to find the epidural depth automatically to make the first attempt to enter the path of the needle into the patient's body while it is clogged with bone and avoid causing a puncture in the surrounding areas of the patient`s back.

Distributed Real-Time Emulation of Formally-Defined Patterns for Safe Medical Device Control [PDF]
EPTCS 36, 2010, pp. 158-177, 2010 Safety of medical devices and of their interoperation is an unresolved issue causing severe and sometimes deadly accidents for patients with shocking frequency. Formal methods, particularly in support of highly reusable and provably safe patterns which can be instantiated to many device instances can help in this regard. However, this still leaves open

Tissue Classification During Needle Insertion Using Self-Supervised Contrastive Learning and Optical Coherence Tomography [PDF]
arXiv, 2023 Needle positioning is essential for various medical applications such as epidural anaesthesia. Physicians rely on their instincts while navigating the needle in epidural spaces. Thereby, identifying the tissue structures may be helpful to the physician as they can provide additional feedback in the needle insertion process.

Cell-penetrating pepducins targeting the neurotensin receptor type 1 relieve pain [PDF]
Pharmacological Research. 104750 (2020), 2020 Pepducins are cell-penetrating, membrane-tethered lipopeptides designed to target the intracellular region of a G protein-coupled receptor (GPCR) in order to allosterically modulate the receptor's signaling output. In this proof-of-concept study, we explored the pain-relief potential of a pepducin series derived from the first intracellular loop of ...

Limitations of the use of pressure waves to verify correct epidural needle position in dogs [PDF]
, 2013 The use of pressure waves to confirm the correct position of the epidural needle has been described in several domestic species and proposed as a valid alternative to standard methods, namely, control radiographic exam and fluoroscopy. The object of this

Needle guidance with Doppler-tracked polarization-sensitive optical coherence tomography [PDF]
arXiv, 2023 We demonstrate that a simple, unscanned polarization-sensitive optical coherence tomography needle probe can be used to perform layer identification in biological tissues. Broadband light from a laser centered at 1310 nm was sent through a fiber that was embedded into a needle, and analysis of the polarization state of the returning light after ...
