MUTLI-LUMEN TAPERED TIP - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240016632 titled 'MUTLI-LUMEN TAPERED TIP

Simplified Explanation

The present disclosure describes a method for positioning multiple guidewires within a multi-lumen tapered tip. A first guidewire is positioned within a primary guidewire lumen, while a second guidewire is positioned within a secondary guidewire lumen and a shared guidewire lumen. The second guidewire prevents the first guidewire from entering the shared guidewire lumen. A delivery system with the multi-lumen tapered tip is then advanced over the second guidewire, eliminating the possibility of entanglement of multiple guidewires during advancement.

  • The method involves positioning multiple guidewires within a multi-lumen tapered tip.
  • The second guidewire prevents the first guidewire from entering the shared guidewire lumen.
  • The delivery system is advanced over a single guidewire, eliminating the possibility of entanglement.
  • A guidewire exchange is performed by releasing the second guidewire, advancing the first guidewire through and out of the shared guidewire lumen, and advancing the delivery system over the first guidewire to a deployment location.

Potential applications of this technology:

  • Minimally invasive medical procedures requiring the use of guidewires.
  • Catheterization procedures.
  • Endovascular surgeries.
  • Interventional radiology procedures.

Problems solved by this technology:

  • Entanglement of multiple guidewires during the advancement of a delivery system.
  • Difficulty in positioning and exchanging guidewires within a multi-lumen tapered tip.
  • Risk of complications and delays in medical procedures due to guidewire entanglement.

Benefits of this technology:

  • Simplified and efficient guidewire positioning and exchange.
  • Reduced risk of complications and delays in medical procedures.
  • Improved safety and ease of use during minimally invasive procedures.


Original Abstract Submitted

the present disclosure provides a method including positioning a first guidewire within a primary guidewire lumen of a multi-lumen tapered tip. a second guidewire is positioned within a secondary guidewire lumen and a shared guidewire lumen of the multi-lumen tapered tip, the second guidewire preventing the first guidewire from entering the shared guidewire lumen. a delivery system including the multi-lumen tapered tip is advanced over the second guidewire. by advancing the delivery system over a single guidewire, any possibility of entanglement of multiple guidewires during advancement of the delivery system is eliminated. the method further includes a guidewire exchange including releasing the second guidewire from the shared guidewire lumen, advancing the first guidewire through and out of the shared guidewire lumen, and advancing the delivery system over the first guidewire to a deployment location.
