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 first bar, and a second portion extending distally to a second bar. In a close state of the loop, the first and second bars are maintained or housed inside a first cannula. The first cannula may be in contact with a second cannula. Upon desiring to open the loop, the physician may separate the first cannula from the second cannula, allowing the bars to exit the first cannula and disconnect from each other, defining the open state of the loop. In the open state, the loop may be easily retrieved through any ingrowth in the body vessel.
Claims20
A device for treatment in a body vessel, the device comprising:
- a first portion comprising a first elongate body extending distally to a first bar, the first bar comprising a first proximal end and a first distal end;
- a second portion comprising a second elongate body extending distally to a second bar, the second bar comprising a second proximal end and second distal end, the first proximal end being in contact with the second proximal end to join the first and second portions;
- a first cannula disposed about the first elongate body and extending distally about the first and second bars to a first tubular end to maintain the first proximal end in contact with the second proximal end;
- a second cannula disposed about the second elongate body and extending distally to a second tubular end, the second tubular end being in contact with the first tubular end so that the first cannula maintains the first proximal end in contact with the second proximal end, defining a loop in a closed state;
- and
- the first and second tubular ends being slidable so that the first cannula distally extends up to only proximal to the second distal end, defining the loop in an open state, to allow the first proximal end to separate from the second proximal end.
A method for retrieving a device from a body vessel, the body vessel having a longitudinal axis, the method comprising:
- disposing the device within the body vessel, the device comprising:
- a first portion comprising a first elongate body extending distally to a first bar, the first bar comprising a first proximal end and a first distal end;
- a second portion comprising a second elongate body extending distally to a second bar, the second bar comprising a second proximal end and second distal end, the first proximal end being in contact with the second proximal end to join the first and second portions;
- a first cannula disposed about the first elongate body and extending distally about the first and second bars to a first tubular end to maintain the first proximal end in contact with the second proximal end;
- a second cannula disposed about the second elongate body and extending distally to a second tubular end, the second tubular end being in contact with the first tubular end so that the first cannula maintains the first proximal end in contact with the second proximal end, defining a loop in a closed state;
- and
- the first and second tubular ends being slidable so that the first cannula distally extends up to only proximal to the second distal end to allow the first proximal end to separate from the second proximal end, defining the loop in an open state;
- and
- disconnecting the first bar from the second bar to separate the first portion from the second portion in the body vessel.
An apparatus comprising:
- an inner sheath;
- a coupling member;
- and
- a device removably coupled to the inner sheath by way of the coupling member, the device comprising:
- a first portion comprising a first elongate body extending distally to a first bar, the first bar comprising a first proximal end and a first distal end;
- a second portion comprising a second elongate body extending distally to a second bar, the second bar comprising a second proximal end and second distal end, the first proximal end being in contact with the second proximal end to join the first and second portions;
- a first cannula disposed about the first elongate body and extending distally about the first and second bars to a first tubular end to maintain the first proximal end in contact with the second proximal end;
- a second cannula disposed about the second elongate body and extending distally to a second tubular end, the second tubular end being in contact with the first tubular end so that the first cannula maintains the first proximal end in contact with the second proximal end, defining a loop in a closed state;
- and
- the first and second tubular ends being slidable so that the first cannula distally extends up to only proximal to the second distal end, defining the loop in an open state, to allow the first proximal end to separate from the second proximal end.
