METHODS AND ASSEMBLIES FOR DEPLOYING BILIARY STENTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240024138 titled 'METHODS AND ASSEMBLIES FOR DEPLOYING BILIARY STENTS
Simplified Explanation
The abstract describes a stent-deployment assembly that includes a biliary stent and a stent-conveyance tube. The tube has a segment that retains a guidewire and a laterally-breachable portion. In the stent-advancement configuration, the guidewire passes through the tube's apertures and the stent surrounds a proximally displaced tube segment. When the stent reaches the target deployment location, withdrawing the tube in the proximal direction causes the guidewire to breach the laterally-breachable portion, decoupling it from the tube without longitudinal displacement.
- The assembly includes a biliary stent and a stent-conveyance tube with a guidewire-retaining segment and a laterally-breachable portion.
- The guidewire passes through the tube's apertures and the stent surrounds a proximally displaced tube segment for advancement.
- Withdrawing the tube in the proximal direction causes the guidewire to breach the laterally-breachable portion, decoupling it from the tube without longitudinal displacement.
Potential applications of this technology:
- Minimally invasive procedures: The stent-deployment assembly can be used in minimally invasive procedures to deliver and deploy stents in body lumens without the need for extensive surgical interventions.
- Biliary interventions: The assembly is specifically designed for use in biliary interventions, where stents are commonly used to treat obstructions or strictures in the bile ducts.
Problems solved by this technology:
- Guidewire decoupling: The assembly provides a mechanism for decoupling the guidewire from the stent-conveyance tube without the need for longitudinal displacement, reducing the risk of complications or damage during the deployment process.
- Precise stent placement: The assembly allows for precise placement of the stent at the target deployment location within the body lumen, ensuring optimal treatment outcomes.
Benefits of this technology:
- Improved safety: The decoupling mechanism reduces the risk of guidewire-related complications, such as guidewire entanglement or displacement, during stent deployment.
- Enhanced procedural efficiency: The assembly simplifies the stent deployment process by providing a mechanism for guidewire decoupling without the need for additional steps or tools.
- Accurate stent placement: The assembly's design enables precise placement of the stent at the desired location within the body lumen, improving treatment effectiveness.
Original Abstract Submitted
a stent-deployment assembly for use with a guidewire comprises a biliary stent and an elongated stent-conveyance tube comprising a guidewire-retaining segment that includes respective distal and proximal apertures defining a guidewire-path therethrough, and a lengthways laterally-breachable portion. in a stent-advancement configuration, the guidewire passes through the respective apertures so as to interiorly traverse the guidewire-retaining segment, and the stent is arranged to surround a stent-conveyance tube segment that is proximally displaced from the guidewire-retaining segment, for advancement of the stent together with the stent-conveyance tube along the guidewire into a body lumen of a human subject. when the stent is disposed, in the stent-advancement configuration, at a target deployment location within the lumen, a proximal-direction withdrawal of the stent-conveyance tube is effective to cause the guidewire to breach the laterally-breachable portion of the guidewire-retaining segment so as to decouple the guidewire from the tube without longitudinal displacement of the guidewire.
