Stabilizing Transnasal Balloon Sheath Patent US12599365B2
Summary
USPTO granted patent US12599365B2 to Medtronic, Inc. for a transnasal transesophageal balloon catheter with compliant balloons, fluid channels, and a probe guide lumen of less than 15 French. The patent covers technology for slidably and rotatably receiving an ultrasound probe during transnasal procedures.
What changed
USPTO granted Medtronic patent US12599365B2 for a stabilizing transnasal balloon sheath. The invention includes at least one compliant balloon attached to a tubular body external surface, with structures extending from the internal surface forming a probe guide lumen of less than 15 French (5 mm). Elongate fluid channels interspersed among the structures transport fluid to inflate or deflate the balloon.
Competitors developing transnasal balloon catheters with similar probe guide configurations should review this patent for potential infringement risks. The patent does not impose compliance obligations on third parties but establishes enforceable IP rights that could affect product development strategies in the medical device sector.
What to do next
- Monitor for potential infringement by competitors
- Review patent claims for competitive landscape assessment
- Consult IP counsel regarding freedom-to-operate analysis

Abstract
A transnasal transesophageal balloon catheter includes at least one compliant balloon attached to the external surface of the tubular body. An arrangement of structures extend away from the internal surface of the tubular body, and exposed probe guide surfaces on the structures form a lumen with a diameter of less than about 15 French (Fr) (5 mm) extending from the proximal end to the distal end of the tubular body and configured to slidably and rotatably receive the ultrasound probe. An arrangement of elongate fluid channels are interspersed with the structures. The fluid channels are in fluid communication with the lumen and transport a fluid between a fluid ingress port and a fluid egress port to at least partially inflate or deflate the balloon.
