TRANSSEPTAL SYSTEMS AND METHODS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240016484 titled 'TRANSSEPTAL SYSTEMS AND METHODS

Simplified Explanation

The abstract describes a transseptal system that includes a needle, a guidewire, a handle, and a dilator. The handle has a needle passage and a guidewire passage to receive the needle and guidewire respectively. The dilator is coupled to the handle and has a lumen with a distal region and a proximal region. The proximal region of the lumen can simultaneously receive the needle body and the guidewire, while the distal region can individually receive either the needle or the guidewire. This system allows for a transseptal puncture and access procedure without the need for multiple instrument exchanges.

  • The transseptal system includes a needle, guidewire, handle, and dilator.
  • The handle has passages to receive the needle and guidewire.
  • The dilator is connected to the handle and has a lumen with distal and proximal regions.
  • The proximal region of the lumen can accommodate both the needle and guidewire.
  • The distal region of the lumen can individually receive either the needle or guidewire.
  • This system enables a transseptal puncture and access procedure without multiple instrument exchanges.

Potential Applications:

  • Transseptal procedures in cardiology, such as accessing the left atrium for interventions.
  • Minimally invasive surgeries requiring access through tissue barriers.

Problems Solved:

  • Eliminates the need for multiple instrument exchanges during transseptal procedures.
  • Simplifies the process of accessing specific areas through tissue barriers.

Benefits:

  • Reduces procedure time and complexity.
  • Minimizes the risk of complications associated with instrument exchanges.
  • Enhances the efficiency and precision of transseptal procedures.


Original Abstract Submitted

a transseptal system includes a needle, a guidewire, a handle, and a dilator. the handle defines a needle passage to slidably receive the needle, and a guidewire passage to slidably receive the guidewire. the dilator defines a lumen having a distal region and a proximal region. the dilator is coupled to the handle such that the lumen is open to the needle passage and the guidewire passage. the proximal region of the lumen is sized to simultaneously receive the needle body and the guidewire. the distal region is sized to slidably receive one of the needle and the guidewire on an individual basis. a transseptal puncture and access procedure can be performed, including puncturing tissue with the needle followed by immediate advancement of the guidewire into the accessed area, eliminating the need for multiple instrument exchanges during the procedure.
