Abstract
The present disclosure relates to a loop vascular device and a method to retrieve said device from the body vessel of a patient. The loop vascular device comprises a loop having a first portion extending distally to a splitting portion, and a second portion also extending distally to the splitting portion, defining a close state of the loop. The splitting portion may be split such that the first portion is separated from the second portion when in the body vessel, defining an open state of the loop. In the open state, the loop may be easily retrieved through ingrowth in the body vessel, reducing or eliminating possible negative effects to the vessel wall.
Claims20
A device for treatment in a body vessel, the body vessel having a vessel wall, the device comprising:
- a loop comprising a first portion extending distally to a splitting portion and a second portion extending distally to the splitting portion, defining a closed state of the loop, wherein the first and second portions comprise a first electrical resistance and the splitting portion comprises a second electrical resistance being greater than the first electrical resistance, such that current flows through the device, causing the splitting portion to split or blow apart when in the body vessel, defining an open state of the loop.
A device for treatment in a body vessel, the body vessel having a vessel wall, the device comprising:
- a loop comprising a first portion extending distally to a splitting portion and a second portion extending distally to the splitting portion, defining a closed state of the loop,
- wherein the first and second portions comprise first material, and the splitting portion comprises a second material being different from the first material such that the splitting portion is weakened to split the first portion from the second portion when in the body vessel, defining an open state of the loop.
A method for retrieving a device from a body vessel, the body vessel having a vessel wall, the method comprising:
- disposing the device within the body vessel, the device comprising:
- a loop comprising a first portion extending distally to a splitting portion and a second portion extending distally to the splitting portion, defining a closed state of the loop, wherein the first and second portions comprise a first material, and the splitting portion comprises a second material being different from the first material such that the splitting portion is weakened to split the first portion from the second portion when in the body vessel, defining an open state of the loop;
- splitting the first portion from the second portion in the body vessel;
- and
- retrieving the device from the body vessel.
