Balloon catheter with linear projections on inner and outer surfaces
A recently granted patent (Publication Number: US11679242B2) describes a balloon catheter with unique features. The catheter includes a balloon made of film and an inflation/deflation portion. The inflation/deflation portion consists of linear projections that extend along the outer and inner surfaces of the film in a thickness direction.
In the first claim, the balloon catheter features an inner projection that projects from the inner surface of the film towards the inside of the balloon. The inflation/deflation portion includes an inflatable straight tube portion and a pair of tapered portions on opposite sides of the straight tube portion. The outer projection, located at the straight tube portion, extends throughout the straight tube portion in the axial direction of the balloon. The inner projection, situated at one of the tapered portions, extends throughout that specific tapered portion in the axial direction. Both the outer and inner projections are positioned at the same location in the circumferential direction of the balloon.
The second claim of the patent describes a similar balloon catheter with some variations. The inner projection is still present, projecting from the inner surface towards the inside of the balloon. The inflation/deflation portion includes an inflatable straight tube portion and a pair of tapered portions. However, in this claim, the inner projection is specifically located at the tip-end side tapered portion of one of the tapered portions. The outer projection remains at the straight tube portion and extends throughout it in the axial direction. Again, both projections are positioned at the same location in the circumferential direction of the balloon.
The third claim introduces an additional inner projection. Similar to the second claim, the inner projection is located at the tip-end side tapered portion of one of the tapered portions. However, in this claim, there is another inner projection at the other tapered portion. The outer projection remains at the straight tube portion, and all the inner projections extend throughout their respective tapered portions in the axial direction. As in the previous claims, the outer and inner projections are positioned at the same location in the circumferential direction of the balloon.
These claims highlight the unique design of the balloon catheter, with linear projections on the outer and inner surfaces of the film in the inflation/deflation portion. The specific placement and configuration of these projections contribute to the functionality and performance of the catheter.
