Microelectrode recordings from the human cervical vagus nerve during maximal breath‐holds

open access: yesExperimental Physiology, EarlyView.
Abstract Voluntary breath‐holds can be sustained for a long time following training, but ultimately, regardless of duration, the asphyxic break‐point is reached and the apnoea terminated. The physiological changes occurring during the apnoea include a marked increase in sympathetically‐mediated vasoconstriction in non‐essential organs, such as skeletal

Perfusion balloon catheter

The American Journal of Cardiology, 1988
An autoperfusion balloon catheter was developed to allow passive myocardial perfusion during balloon inflation, through a central lumen and multiple side holes in the shaft proximal and distal to the balloon. This report reviews preliminary experimental animal data and initial human clinical experience with this device.

Dilatation and the Expanding Balloon Catheter. Advantages of the Expanding Balloon Catheter [PDF]

open access: possible, 1983
The expanding balloon catheter was first presented by our group in 1977 [1–4] and has been commercially available for 6 months (Surgimed, Copenhagen). The major differences between this new catheter and that ones used so far are the following: 1.

Balloon Dilation

Pediatric Clinics of North America, 1990
Catheter therapy has gained an important role in the treatment of congenital heart disease. The cumulative experience with vascular and valvular balloon dilations has demonstrated low mortality and morbidity with short-term results similar to surgery. Currently, balloon dilation is an accepted treatment for valvular pulmonary stenosis, distal pulmonary
