Bioengineered Interfaces for Peripheral Nerve Sensory Restoration

Advanced Materials, EarlyView.
Half of amputees abandon their prosthetics for lack of feeling. This review charts the full path from peripheral nerve injury to restored sensation, through surgical, regenerative, noninvasive, and implanted approaches, and shows how injury type and interface material properties determine which strategy can deliver naturalistic feedback, and why ...

Bilateral high origin and superficial trajectory of the deep femoral artery: clinical and applied anatomy

Autopsy and Case Reports
The anatomy of the femoral triangle is explored in various approaches, ranging from pulse verification to invasive catheterization procedures. Within the femoral triangle, the deep femoral artery is one of the vessels reported to present several ...

Surgical repair of deep femoral artery aneurysm complicated by deep vein thrombosis and pulmonary embolism

Journal of Vascular Surgery Cases and Innovative Techniques, 2021
Isolated deep femoral artery aneurysms are rare and tend to be large at the time of diagnosis owing to their deep anatomic location. Deep femoral artery aneurysms are often complicated by rupture, with subsequent lower limb amputation.

Self‐Assembling Copolymers Encapsulating Single Endothelial Cells Induce Endogenous ECM Deposition and Vascular Regeneration

Advanced Materials, EarlyView.
This study presents the first demonstration of stable sub‐50‐micron single‐cell GPM vesicles fabricated through the intrinsic self‐assembly of an amphiphilic copolymer. Hierarchical assembly of cell containing GPM vesicles into microspheres enable tunable, sustained cell delivery with immune protection.

A Superlubricated Magnetically Steerable Microcatheter with Integrated Optical and Fluidic Channels

Advanced Robotics Research, EarlyView.
A magnetically steerable microcatheter with integrated optical and fluidic channels is developed for multifunctional navigation in tortuous anatomical environments. A surface‐grafted hydrogel coating enables low‐friction actuation. The device demonstrates stable light and fluid delivery during magnetic manipulation, offering a compact platform for ...

Evaluation of the Femoral Artery IMT as a Risk Factor of Cardiovascular Disease

Journal of Surgical Ultrasound, 2019
Purpose: The carotid artery intima-media thickness (IMT) is a risk factor for atherosclerosis that can predict the association of cardiovascular disease. Despite this, there have been few studies on the femoral artery IMT.

Retrograde mesenteric perfusion from the deep femoral artery in a patient with a recurrent anastomotic aneurysm in the groin: a case report

Frontiers in Surgery, 2023
In patients with atherosclerotic disease in two of the three main vessels in the splanchnic circulation, symptoms of chronic mesenteric ischemia may arise, depending on the disease chronicity and the presence of mesenteric collateral pathways.

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

Advanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

Retrograde cannulation of femoral artery: A novel experimental design for precise elicitation of vasosensory reflexes in anesthetized rats

MethodsX, 2020
Vasosensory reflex responses are elicited by instillation of nociceptive agents in a segment of peripheral blood vessel. A novel method for the stimulation of perivascular afferents was designed by retrograde cannulation of femoral artery, using a 24G ...
