I'm looking for a range of disposable medical Nitinol stone extractor retrieval baskets suitable for urinary use.

Please provide details on available models and their specifications, including any design features that enhance performance during procedures. Additionally, I'd appreciate information on pricing, minimum order quantities, and lead times for production and delivery. If possible, send along any product catalogues or brochures that outline your offerings. This will help in making a well-informed decision for our procurement needs. Thank you!
