Currently, bioresorbable electronic devices are predominantly fabricated by complex and expensive vacuum-based integrated circuit (IC) processes. Here, a low-cost manufacturing approach for bioresorbable conductors on bioresorbable polymer substrates by evaporation-condensation-mediated laser printing and sintering of Zn nanoparticle is reported. Laser sintering of Zn nanoparticles has been technically difficult due to the surface oxide on nanoparticles. To circumvent the surface oxide, a novel approach is discovered to print and sinter Zn nanoparticle facilitated by evaporation-condensation in confined domains...

Beneficial properties of bioresorbable vascular scaffolds (BVS) regarding to vasomotility restoration and no caging of the vessel make them attractive devices in chronic total occlusions (CTO) revascularization. However, more evidence is needed attending to their use in this specific setting. We aim to determine feasibility and safety of BVS use in CTO revascularization attending to struts coverage and apposition, as well as re-stenosis and stent thrombosis (ST) rates. 29 BVS were deployed in 9 CTO lesions revascularization (mean J-CTO score ≥3) with an acute procedural success rate of 100%...

Aims: To compare the long-term safety and efficacy of bioresorbable vascular scaffold (BVS) with everolimus-eluting stent (EES) after percutaneous coronary interventions. Methods and Results: A systematic review and meta-analysis of randomized clinical trials comparing clinical outcomes of patients treated with BVS and EES with at least 24 months follow-up was performed. Adjusted random-effect model by the Knapp-Hartung method was used to compute odds ratios (OR) and 95% confidence intervals (CI)...

OBJECTIVES: This study investigated the vasomotor response to nitroglycerine (NTG) up to 5 years after ABSORB implantation. BACKGROUND: There are no data regarding long-term vasomotor response after everolimus-eluting bioresorbable vascular scaffold ABSORB implantation. METHODS: We performed quantitative coronary angiography of the scaffolded and proximal and distal adjacent segments of patients from ABSORB Cohort B study before and after 200 μg of intracoronary NTG at 2, 3, and 5 years of follow-up...

OBJECTIVES: The purpose of this study was to evaluate the economic impact of the Absorb bioresorbable vascular scaffold compared with the Xience everolimus-eluting stent in patients undergoing percutaneous coronary intervention. BACKGROUND: The ABSORB III trial (Everolimus-Eluting Bioresorbable Scaffolds for Coronary Artery Disease) demonstrated that the Absorb scaffold was noninferior to the Xience stent with respect to target lesion failure at 1 year. Whether health care costs differ between the Absorb scaffold and the Xience stent is unknown...

Bioresorbable vascular scaffold (BVS) stents have been proposed recently as an elegant technique for treatment of coronary artery disease. However, perspective that these "dissolvable" stents will replace conventional metallic stents in broad spectrum of clinical conditions and patient categories in the near future has been moderated by non-negligible incidence of stent thrombosis (ST). Mechanical factors, such as strut thickness and malapposition have been implicated in increased risk of BVS ST. Presently described is case of immediate partial BVS ST in a young male related to technical procedural problem, rather than mechanical problem...

AIM: Laparoscopic surgery causes fewer postoperative adhesions than laparotomy and adhesion barriers are used to lessen the chance of adhesion. Sodium hyaluronate and carboxymethylcellulose (SH-CMC), a bioresorbable membrane, is effective in preventing adhesions. However, its properties make it difficult to insert the film into the abdominal cavity and to place it into the target area during laparoscopic surgeries. Here we report a novel technique for applying SH-CMC during laparoscopic surgeries by using cut-off surgical glove fingers...

Overlapping permanent scaffolds carries a long-term risk of target vessel failure due to late malapposition and the development of neoatherosclerosis. Potentially, overlapping bioresorbable scaffold (BRS) may lead to lower long-term risk. The GHOST-EU registry reported similar short- and mid-term risks in patients with and without BRS overlap. Larger size studies with longer follow-up are needed to confirm the safety of BRS overlap.

Paclitaxel is one of the most efficient anticancer agents, but the conventional dosage formulations cause many side effects. PLA-PEG filomicelles are promising carriers of paclitaxel because high loading capacity and long term release can be achieved. Slow release of cytostatic drugs is very advantageous due to prolonged exposure of tumor cells to cytostatic over multiple cell cycles. The aim of this study was to evaluate the potential of bioresorbable PLA-PEG filomicelles for prolonged delivery of paclitaxel...

The replacement of small-diameter vessels is one of the main challenges in tissue engineering. Moreover, the surface modification of small-diameter vascular grafts (SDVG) is a key factor in the success of the therapy due to their increased thrombogenicity and infection susceptibility caused by the lack of a functional endothelium. In this work, electrospun scaffolds were prepared from blends of poly(L-lactic acid) (PLLA) and segmented polyurethane (PHD) with a composition designed to perform as SDVG inner layer...

BACKGROUND: Recent evidence suggests that bioresorbable vascular scaffolds (BVS) are associated with an excess of thrombotic complications compared with metallic everolimus-eluting stents (EES). OBJECTIVE: We sought to investigate the comparative effectiveness of the FDA approved Absorb BVS versus metallic EES in patients undergoing percutaneous coronary intervention at longest available follow-up. METHODS: We searched MEDLINE, Scopus and web sources for randomized trials comparing the BVS and EES...

In the era of drug-eluting stents, large-scale randomized trials and all-comer registries have shown excellent clinical results. However, even the latest-generation drug-eluting stent has not managed to address all the limitations of permanent metallic coronary stents, such as the risks of target lesion revascularization, neoatherosclerosis, preclusion of late lumen enlargement, and the lack of reactive vasomotion. Furthermore, the risk of very late stent, although substantially reduced with newer-generation drug-eluting stent, still remains...
