Abstract
Disclosed is a biomedical device being introduced by a hollow tube having a longitudinal axis in a subject in a minimally invasive surgery procedure for watertight sealing of an opening including at least two assemblies, each assembly including one flap connected to one arm, the arm having an longitudinal axis; the assemblies including a delivery configuration, a deployed configuration, and a sealed configuration and outwards deployment unit for switching from the delivery configuration to the deployed configuration and inwards deployment unit for switching from the deployed configuration to the sealed configuration. Also disclosed is a kit of parts including an outer hollow tube, an inner hollow tube, and a related biomedical device.
Claims26
A biomedical device for watertight sealing of an opening in a subject during a minimally invasive surgery procedure, the biomedical device configured for being introduced in said subject by an outer hollow tube and comprising:
- at least two assemblies, each assembly comprising one flap as a proximal part, and one arm as a distal part;
- and
- assembling means connected to the at least two assemblies, said assembling means being configured such that the proximal part of each assembly is located in a plane perpendicular to a reference axis A, wherein,
- said one arm of each assembly includes a first connection portion and said one flap of each assembly has a second connection portion, the first connection portion and the second connection portion forming a hinge,
- the hinge connecting the first connection portion of said one arm to the second connection portion of said one flap such that an axis of connection is formed at the hinge with said one arm being rotatably connected to said one flap between a first relative position in which the arm and the flap form an angle of substantially 180° and a second relative position in which the arm and the flap form an angle of substantially 90°,
- the assemblies each
- having a delivery configuration, a deployed configuration, and a sealed configuration;
- the assemblies each having i) outwards deployment means for switching from the delivery configuration to the deployed configuration, and ii) inwards deployment means for switching from the deployed configuration to the sealed configuration;
- wherein:
- in the delivery configuration, the flap and the arm of each assembly are oriented parallel to the reference axis A, each assembly extends along the direction substantially parallel to the reference axis A, and the at least two assemblies together form a hollow cylinder for receiving an inner hollow tube therethrough;
- an axis of the inner hollow tube coinciding with the reference axis A, the flap and the arm forming an angle of substantially 180°;
- in the deployed configuration, the flap of each assembly remains parallel to the reference axis A along the inner hollow tube, and the arm of each assembly is deployed outwardly relative to the reference axis A and positioned at substantially 90° relative to the reference axis A, the flap and the arm forming an angle of substantially 90°;
- and
- in the sealed configuration, the flap of each assembly is deployed inwardly relative to the reference axis A and positioned at substantially 90° relative to the reference axis A, such that the flaps are joined in an edge to edge arrangement thereby closing and sealing said opening in a watertight manner, and the arm of each assembly remains positioned at substantially 900 relative to the reference axis A, the flap and the arm forming an angle of substantially 180°.
