Abstract

Embodiments of a malecot device may include magnets configured to maintain a deployed configuration of malecot wings of the device. A malecot device may also include a deployment member that is removably attached thereto.

Claims

1. A malecot device comprising:

an elongate generally tubular body including a proximal end and a distal end with an elongate body lumen disposed through its length;

where the body includes a plurality of generally parallel elongate slits defining lateral sides of a plurality of malecot wings, and each malecot wing has a proximal wing portion and a distal wing portion;

where the malecot wings are configured to deploy by folding outward from a central longitudinal axis of the body upon a deployment action moving the proximal and distal body ends longitudinally toward each other; and

where at least one of the malecot wings comprises at least a first magnet in one of its proximal or distal wing portion and a second magnet in the other of its proximal or distal wing portion, and the first and second magnets are configured to engage each other when the first malecot wing is folded outward.

2. The malecot device of claim 1, where the slits are oriented generally parallel with a central longitudinal axis of the body.

3. The malecot device of claim 1, where the slits are oriented generally at an angle relative to a central longitudinal axis of the body.

4. The malecot device of claim 1, where at least one of the malecot wings comprises:

a third magnet and a fourth magnet that are configured to engage each other when the at least one malecot wing is folded outward.

5. The malecot device of claim 1, where the elongate tubular body includes a cross-sectional geometry selected from circular, angled polygonal, rounded polygonal, and non-circular curvilinear.

6. The malecot device of claim 1, further comprising:

at least one of a score and a molded feature on a surface of the body configured to promote bending in the immediate region of the feature.

7. The malecot device of claim 6, where the at least one of a score and a molded feature is disposed in a location selected from the group consisting of:

adjacent a proximal end of a malecot wing,

adjacent a distal end of a malecot wing,

between proximal and distal ends of a malecot wing,

on a lumen-facing surface;

on an outside-facing surface; and

any combination thereof.

8. The malecot device of claim 1, where each of the plurality of malecot wings includes a magnet.

9. The malecot device of claim 1, further comprising an elongate deployment member configured for deployment of the device.

10. The malecot device of claim 1, further comprising:

an elongate deployment member disposed coaxially through at least a portion of the elongate body lumen and accessible from the proximal end of the body.

11. The malecot device of claim 10, further comprising:

the deployment member being fixedly attached to the body in at least one attachment location that is distal of the malecot wings; and

a length of the deployment member proximal of the attachment location being slidably disposed relative to the body, such that a proximal movement of the deployment member relative to the body will deploy the malecot wings.

12. The malecot device of claim 11, further comprising:

the deployment member being removably attached to the body in at least one attachment location that is distal of the malecot wings; and

a length of the deployment member proximal of the attachment location being slidably disposed relative to the body, such that a proximal movement of the deployment member relative to the body will deploy the malecot wings.

13. The malecot device of claim 12, where the deployment member further comprises:

at least a third magnet oriented to engage one of the first magnet and the second magnet.

14. The malecot device of claim 13, where the deployment member further comprises:

at least a fourth magnet oriented to engage the other of the first magnet and the second magnet.

15. The malecot of claim 12, where the removable attachment comprises a threaded connection.

16. The malecot of claim 12, where the deployment member comprises an expandable member configured to releasably engage an inner surface of the body.

17. A malecot device comprising:

at least one malecot wing, the at least one malecot wing including a first magnet and a second magnet, where the first and second magnets are configured to engage each other and retain a deployed configuration of the malecot wing.

18. The malecot device of claim 17, further comprising:

at least one catheter portion.

19. The malecot device of claim 17, further comprising:

a deployment member.

20. The malecot device of claim 18, where the deployment member is removable.
