==CATHETER SHAFT WITH UNIFORM BENDING STIFFNESS CIRCUMFERENTIALLY - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240033474 titled 'CATHETER SHAFT WITH UNIFORM BENDING STIFFNESS CIRCUMFERENTIALLY

==Simplified Explanation==

The abstract describes a catheter shaft that consists of an inner layer and an outer layer. The inner layer forms the innermost surface of the catheter shaft and creates a lumen. The outer layer forms the outermost surface of the catheter shaft and is made up of alternating segments of two different polymers. Each segment extends along the entire length of the catheter shaft in an axial direction. The first polymer has a higher durometer and melting temperature, while the second polymer has a lower durometer and melting temperature.

* The catheter shaft is made up of two layers - an inner layer and an outer layer.
* The inner layer defines the innermost surface of the catheter shaft and creates a lumen.
* The outer layer defines the outermost surface of the catheter shaft.
* The inner layer is made of a first polymer with a higher durometer and melting temperature.
* The outer layer is made of alternating segments of the first polymer and a second polymer.
* The second polymer has a lower durometer and melting temperature than the first polymer.
* Each segment of the alternating first and second segments extends along the entire length of the catheter shaft in an axial direction.
* The catheter shaft is formed via extrusion.

Potential Applications:
* Medical catheters
* Intravenous (IV) catheters
* Urinary catheters
* Cardiac catheters
* Endoscopic catheters

Problems Solved:
* Provides a catheter shaft with improved flexibility and softness.
* Allows for easier insertion and maneuverability during medical procedures.
* Reduces the risk of tissue damage or discomfort for patients.

Benefits:
* Enhanced patient comfort during catheterization procedures.
* Improved flexibility and maneuverability for medical professionals.
* Reduced risk of tissue damage or irritation.
* Increased durability and longevity of the catheter shaft.


==Original Abstract Submitted==

a catheter shaft includes an inner layer defining an innermost circumferential surface of the catheter shaft and defining a lumen of the catheter shaft, and an outer layer defining an outermost circumferential surface of the catheter shaft. the inner layer is formed by a first polymer having a first durometer and a first melting temperature. the outer layer is formed by alternating first and second segments of the first polymer and a second polymer, respectively, that alternate in a circumferential direction. the second polymer has a second durometer softer than the first durometer and a second melting temperature lower than the first melting temperature. each segment of the alternating first and second segments extend in an axial direction for substantially an entire length of the catheter shaft. a method of forming the catheter shaft via extrusion is also disclosed.
