Concept of the homemade coronary stent: Experimental results and initial clinical experience

Transarterial wall oxygen gradients at the deployment site of an intra-arterial stent in the rabbit

“…Increasing circumferential and radial wall stresses could lead to a decrease in artery wall oxygen delivery and artery wall hypoxia following stent deployment. Currently, clinicians limit stent dilation to a ratio of 1.2:1 (stent diameter to normal artery diameter) to minimize the risk of artery rupture (12,18). These data relating to circumferential and radial stresses to artery wall hypoxia may be another reason to limit the degree of artery dilation following stent deployment.…”

Long-term biocompatibility evaluation of a novel polymer-coated stent in a porcine coronary stent model

“…Stent implantation in the right coronary artery and left anterior descending coronary artery or left circumflex coronary artery was performed according to the method described by De Scheerder et al [14,19]. The guiding catheter was used as a reference to obtain a balloon-toartery ratio of 1.1-1.2 : 1.…”

“…Angiographic analysis of stented vessel segments was performed before stenting, immediately after stenting and at follow-up using the Polytron 1000-system as described previously by De Scheerder et al [14,19]. The diameter of the vessel segments was measured before stent implantation, immediately after stent implantation and at follow-up.…”

Cinical and angiographic outcome after implantation of a home-made stent for complicated coronary angioplasty

“…Not surprisingly, our concept to handmake a stent at home originated from the persistent refusal of our national health care system to reimburse coronary stents for any indication. The design of the stent, the experimental work, as well as the first in-hospital results have recently been described [4,5]. In the present study we report our extended in-hospital experience with this novel device for bailout indications or as a treatment of suboptimal angiographic results.…”

“…The home-made, balloon-expandable, stainless steel, coil stent has previously been described; the stenting procedure and the periprocedural management has been detailed as well [5]. Briefly, when, after the balloon inflation(s), the decision to stent was made, in general, a 15-16 mm long device was manually crimped on the semicompliant balloon that had been used for the conventional angioplasty.…”
