Benefits of technology

This technology has several benefits that make it better than previous methods for producing certain types of chemicals or products with improved properties such as increased efficiency or reduced production costs compared to older techniques like chemistry.

Problems solved by technology

Technological Problem addressed in this patents relates to improving the convenience and stability of temporary intravascular (IV) devices used during medical procedures such as angioplasty or stenosis treatment. Current systems require manual withdrawal after placement due to their instability caused by tilting or unstable placements. There also exist issues related to retrieval difficulties associated with current methods involving radioactive markers attached to the patient' s body.

Abstract

The invention belongs to the technical field of medical devices, and discloses a novel inferior vena cava filter system and an intelligent recovery system thereof. The system is provided with a pulling hook positioned at one end, the pulling hook is connected with a connecting strip, the connecting strip penetrates a filter, one end of the connecting strip extends out of the filter, the middle ofthe filter comprises a degradable section, and a compression spring is arranged between the filter and the connecting strip. According to the system, the middle of the filter is set into the degradable section, two ends of the filter are set into non-degradable sections, and the degradable section can be completely degraded after the filter is placed into an in-vivo blood vessel. The filter is changed into two separate filters after the degradable section is completely degraded, and the filter is contracted under the action of the spring and recovered by the pulling hook. The system is reasonable in structure, safe, firm, reliable in performance and convenient to operate and use and provided with an ideal recyclable vena cava filter.
