The medicament injector is configured to inject the chemotherapy medicament through the stopcock, the drain lumen, and into an environment of the distal tip within a patient's organ without leakage of the chemotherapy medicament from the patient into an environment of the patient. The medicament pressure reservoir is configured to store negative pressure that withdraws from the organ used chemotherapy medicament through the drain lumen and the stopcock and holds the used chemotherapy medicament in the medicament pressure reservoir without leakage of the used chemotherapy medicament into the environment of the patient."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Closed-system bladder drug administration catheter and methods for administering drugs in a closed system","description":"A closed-system, drug administering catheter assembly includes a transfer adapter, a stopcock, a medicament injector containing chemotherapy medicament, a medicament pressure reservoir, and a urethral","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11266815","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
