Backstory: Resistant hypertension, a condition affecting millions globally, poses a significant challenge to healthcare systems. The Paradise ultrasound renal denervation system represents a perhaps groundbreaking non-pharmacological approach to managing this difficult-to-treat form of high blood pressure, offering hope to patients who haven’t responded to conventional therapies.
otsuka Medical Devices Co., Ltd. announced today the receipt of manufacturing and marketing approval in Japan for the Paradise ultrasound renal denervation (uRDN) system. this innovative system is designed to treat resistant hypertension – high blood pressure that remains uncontrolled despite the use of three or more different medications, including a diuretic.
The Paradise uRDN system was developed by Recor Medical, Inc., a U.S.-based subsidiary of Otsuka Medical Devices. the approval in Japan is based on compelling data from the RADIANCE-HTN TRIO study, a rigorous randomized, sham-controlled clinical trial conducted across the United States and Europe.
The RADIANCE-HTN TRIO study enrolled patients already receiving a standardized triple antihypertensive therapy regimen.Results demonstrated a statistically significant and clinically meaningful reduction in daytime ambulatory systolic blood pressure at two months post-treatment with the Paradise uRDN system. Importantly, the system exhibited a consistently favorable safety profile throughout the duration of the study.
Otsuka Medical Devices confirmed that a postmarket surveillance study will be conducted in Japan, adhering to all local regulatory requirements. This ongoing monitoring will provide further insights into the long-term safety and efficacy of the Paradise system within the Japanese population.
The paradise uRDN system has already secured regulatory approvals in key markets, including the United states (FDA approval) and Europe (CE Mark approval). To ensure comprehensive and long-term data collection, the GPS postmarket registry is actively enrolling patients in the European Union, United Kingdom, and United States, with plans for expansion to a global scale.
“This approval marks a significant milestone in our commitment to providing innovative solutions for patients with resistant hypertension,” stated a representative from Otsuka Medical Devices.
“We believe the Paradise system has the potential to transform the treatment landscape for this challenging condition.”
Renal denervation, the underlying principle of the Paradise system, involves using ultrasound energy to disrupt the nerves surrounding the renal arteries. This disruption helps to regulate blood pressure by reducing sympathetic nervous system activity. The Paradise system’s unique ultrasound-based approach aims to offer a precise and targeted treatment option.
Understanding Resistant Hypertension: Trends and Insights
Resistant hypertension is a growing global health concern, frequently enough linked to factors like aging populations, increasing rates of obesity, and lifestyle factors. Current estimates suggest that 10-30% of hypertensive patients experience resistance to conventional therapies. The progress of novel treatment modalities,such as renal denervation,is crucial to address this unmet medical need. Future research will likely focus on identifying ideal patient populations for uRDN and optimizing treatment protocols to maximize efficacy and long-term benefits.

CATL’s Naxtra Sodium-Ion Battery Set to Disrupt EV IndustryTable of Contents August 17, 2025 - Contemporary Amperex Technology Co. Limited (CATL), the world’s leading battery manufacturer [[1]], is poised to introduce a groundbreaking sodium-ion battery, dubbed Naxtra, that could significantly lower the cost of electric vehicles and extend battery lifespan. Production is ramping up,with initial deliveries to six automakers slated for 2026. A Leap in Battery TechnologyThe Naxtra battery represents a strategic shift away from reliance on lithium, nickel, manganese, and cobalt – materials often subject to price volatility and geopolitical concerns.Rather,it utilizes sodium,an abundant and inexpensive element commonly found in salt. This innovative approach is projected to reduce battery production costs to approximately 10% of current lithium-ion battery prices. CATL initially unveiled plans for the sodium-ion battery in April 2025 alongside other advancements, but is now moving swiftly toward large-scale production. this commitment underscores the company’s confidence in the technology’s potential to reshape the energy storage landscape. How Naxtra Differs from Existing BatteriesWhile sodium-ion batteries have been explored for years, previous iterations suffered from lower energy density and increased weight, limiting their suitability for automotive applications. CATL’s Naxtra battery overcomes these limitations with an electrolyte designed to prevent dendrite formation and degradation, ensuring stable performance across a wide temperature range. the battery operates effectively between -40°C and +70°C, maintaining 90% of its discharge power even at -40°C. This resilience is a notable advantage over customary lithium-ion batteries, which can experience performance drops in extreme temperatures. Key Specifications of the Naxtra Battery
Did You Know? Sodium-ion batteries eliminate the risk of thermal runaway, a common safety concern with lithium-ion batteries, as they lack components that support combustion. Building on LFP TechnologyCATL’s development of the Naxtra battery builds upon its success with Lithium Iron Phosphate (LFP) batteries, which already offer a cost-effective alternative to traditional lithium-ion chemistries. LFP batteries currently represent 40-70% of the cost of comparable lithium-ion batteries, providing a 30-60% cost reduction. [[3]] The Naxtra battery promises to further reduce costs,potentially making EVs more accessible to a wider range of consumers. Northvolt, a European battery manufacturer, previously announced a solid-state sodium-ion battery with a comparable energy density in 2023, but faced challenges in scaling production. CATL’s approach, utilizing a more conventional electrolyte, appears to be accelerating the path to commercialization. Pro Tip: The extended cycle life of the Naxtra battery – exceeding 10,000 cycles – translates to a potential lifespan of 5 million kilometers, offering exceptional long-term value. Impact on the EV MarketThe introduction of the Naxtra battery is expected to intensify competition within the electric vehicle market. With a projected cost reduction of up to 80-90% compared to lithium-ion batteries, automakers utilizing Naxtra technology could offer EVs at significantly lower price points – potentially reducing costs by 7,000 to 10,000 euros per vehicle. This cost advantage could force other battery manufacturers and automakers to adopt similar technologies or risk losing market share. Will this shift lead to a more affordable and enduring future for electric mobility? What innovations will emerge as competitors respond to CATL’s breakthrough? The development of sodium-ion batteries represents a crucial step towards diversifying battery chemistries and reducing reliance on critical materials. This trend aligns with broader sustainability goals and efforts to build a more resilient supply chain for the EV industry.Ongoing research focuses on further improving energy density and cycle life of sodium-ion batteries, paving the way for even more advanced energy storage solutions in the future.

Former Quezon City mayor Herbert Bautista is facing two graft cases filed by the Office of the Ombudsman before the Sandiganbayan. The cases involve two government projects in 2019, with former city administrator Aldrin Cuña named as co-accused in both cases. The first case involves the release of the full payment of P32.107 million to an IT firm for the procurement of online occupation permitting and tracking system and others, while the second case involves the payment of the full amount of P25.342 million to another firm for the installation of solar power system and waterproofing works for a civic center building. The bail bond recommended for each of the accused was P90,000 for each of the two graft cases. The cases were received by the Sandiganbayan on March 15, 2023, with the first case going to the 7th Division and the second case going to the 3rd Division. Bautista supposedly entered into a contract with the firms and approved the release of full payment despite the absence of a specific appropriation ordinance enacted by the Sangguniang Panglungsod. |
