Problems solved by technology

Even though Cole discloses a delivery system capable of connecting small diameter hollow bodies in an end-to-end manner, such fixtures do not precisely manipulate the delivery system
[0009] Currently, there is no device, delivery system or method capable of joining small diameter hollow bodies together in a precise and repeatable manner

Embodiment Construction

[0033] will now see Figure 1-14 A device, system and method for connecting two hollow bodies together in fluid communication will be described. Such as figure 1 with figure 2 As shown in , the device generally includes a frame 100 having at least one magnet 130 mounted thereon. The frame 100 is arranged on the outer wall of the hollow body 10 . A second frame, not shown, is arranged on the outer wall of a second hollow body, also not shown. These magnetic frames connect the two hollow bodies 10 together in fluid communication when the hollow bodies 10 are brought into contact with each other.

[0034] Frame 100 is constructed of a superelastic material. An example of such a superelastic material is nickel-titanium alloy (Ni-Ti). The use of a superelastic material allows the frame 100 to be constrained in a deformed state in order to position the frame 100 comprising such material around the hollow body 10 . For example, the superelastic properties allow the frame 100 ...

Abstract

An apparatus constructed from a super elastic material and having magnetic properties is provided for joining together at least two hollow bodies. The apparatus comprises a frame having at least one magnet mounted to an end thereof. The frame is substantially tubular and is preferably constructed from super elastic materials allowing the frame to assume a first expanded diameter and a second smaller diameter corresponding to the outer wall of a hollow body . The frame can be a wire helix that allows for radial and longitudinal flexing. Frames are disposed over the outer walls of the severed ends of at least two hollow bodies to be joined together. The hollow bodies are placed into contact such that the magnetic forces between the two frames links the two bodies together in tight fluid communication.

Description

technical field [0001] The invention generally relates to a device for interconnecting hollow bodies. In particular, the invention relates to a device composed of a superelastic material that magnetically couples the ends of two hollow bodies so as to maintain fluid contact between the two. Background technique [0002] In the human body there are many hollow bodies, such as blood vessels and catheters, which bring necessary fluids to the internal organs, or are used to drain fluids. From time to time the human body is subject to trauma or other injury that may cause damage or damage to the hollow body. In this case, the damage to the hollow body must be repaired by joining together the severed ends of the hollow body. This must be done in such a way that the two ends of the hollow body are in fluid-tight communication. Incorrect bonding of hollow bodies can have negative consequences. For example, blood vessels that are not properly anastomosed may leak, form a blood cl...
