An updated method for the jugular catheterization of grower pigs for repeated blood sampling following an oral glucose tolerance test.

Laboratory animals
Jugular catheterization is a common procedure used under experimental conditions. However, there is considerable variation in the reported techniques, particularly for grower pigs (>40 kg and <60 kg) when larger volumes of blood per sample (>10 mL) a...

Partial displacement of epidural catheter after patient position change: A case report.

Journal of clinical anesthesia
Epidural catheter migration is a well-known cause of failed anesthesia and complications. One of the factors that affect catheter movement is when patients change their position after skin fixation. We report a case of an epidural catheter placed wit...

Optimization of post-cervical artificial insemination in gilts: Effect of cervical relaxation procedures and catheter type.

Theriogenology
Post-cervical (pC) artificial insemination (AI) has been successfully developed for application in multiparous sows, although it has proved problematic in gilts. This study analyzes the use of pC-AI in gilts by two experiments. In the first experimen...

Robot-assisted retinal vein cannulation with force-based puncture detection: Micron vs. the steady-hand eye robot.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
Retinal vein cannulation is a demanding procedure where therapeutic agents are injected into occluded retina veins. The feasibility of this treatment is limited due to challenges in identifying the moment of venous puncture, achieving cannulation and...

Iliac Limb Perigraft Access with Robotic Catheter Assistance for Type 2 Endoleak Embolization.

Annals of vascular surgery
Retrograde perigraft access to the aneurysmal sac for type 2 endoleak embolization is a relevant alternative to standard transarterial and translumbar approaches. Entering the space between the graft and the iliac artery requires support and pushabil...

Objective Assessment of Endovascular Navigation Skills with Force Sensing.

Annals of biomedical engineering
Despite the increasing popularity of endovascular intervention in clinical practice, there remains a lack of objective and quantitative metrics for skill evaluation of endovascular techniques. Data relating to the forces exerted during endovascular p...

Towards Robot-Assisted Retinal Vein Cannulation: A Motorized Force-Sensing Microneedle Integrated with a Handheld Micromanipulator .

Sensors (Basel, Switzerland)
Retinal vein cannulation is a technically demanding surgical procedure where therapeutic agents are injected into the retinal veins to treat occlusions. The clinical feasibility of this approach has been largely limited by the technical challenges as...

A cooperation of catheters and guidewires-based novel remote-controlled vascular interventional robot.

Biomedical microdevices
Remote-controlled vascular interventional robots (RVIRs) are being developed to increase the overall accuracy of surgical operations and reduce the occupational risks of intervening physicians, such as radiation exposure and chronic neck/back pain. S...
