In developmental biology, invagination is a mechanism that takes place during gastrulation. This mechanism or cell movement happens mostly in the vegetal pole. Invagination consists of the folding of an area of the exterior sheet of cells towards the inside of the blastula. In each organism, the complexity will be different depending on the number of cells. Invagination can be referenced as one of the steps of the establishment of the body plan. The term, originally used in embryology, has been adopted in other disciplines as well. There is more than one type of movement for invagination. Two common types are axial and orthogonal. The difference between the production of the tube formed in the cytoskeleton and extracellular matrix. Axial can be formed at a single point along the axis of a surface. Orthogonal is linear and trough.
Balloon with a multi-layer wall structure for tissue-protective low-pressure sealing of openings and cavities in the patient's body, in particular in the case of periodic fluctuations in the filling pressure value
A multi-layer balloon membrane material (1) is described, which combines one or several layers of elastically deformable material (2) with one or several layers of plastically deformable, inelastic material (3), wherein the inelastic layers counteract the straightening properties of the elastic layers in the case of planar folding or bending of the balloon membrane material. In particular, the cross-sectional area of the eye- or channel-like structures (6) for guiding secretions or liquids, which are typically produced in the region of the plicated invagination of the balloon membrane with dimensional redundancy in organ cavities or body cavities, can be reduced, and in particular stabilized in the case of a periodic change in the balloon filling pressure, whereby an optimal sealing closure or packing result is achieved over as large a range of filling pressure amplitudes as possible.

Body lumen wall invagination
A method for left atrial appendage (LAA) invagination, including:convexing a portion of the LAA wall into the LAA, wherein the convexing includes convexing the LAA wall portion by applying suction from a collapsible suction cup contacting the LAA wall on the LAA wall portion;grasping the convexed LAA wall portion within the LAA, following the convexing; invaginating the LAA at least partly into the left atria (LA) using the convexed LAA portion;wherein the grasping includes controllably collapsing the collapsible suction cup on the convexed LAA portion with a force sufficient to hold the convexed LAA portion during the invaginating.

Pleated fold system, pleated fold / spring system, and method of using the same.
The precator system may have two nesting components, each having one or more windows into which, for example, tubular organ tissue can invaginate when positioned in an open configuration. The invaginated tissue can be secured within the windows when the precator system transitions to a closed configuration. Closing the windows may, for example, act to clamp and pierce the invaginated tubular organ tissue within the windows, thereby securing the invaginated tubular organ tissue within the windows. In some cases, an axially extending spring may be positioned between the two precator systems, and when this assembly is implanted in a tubular organ, the axial extension of the spring may exert an expansive force on the tubular organ, which may stimulate its growth.

Left atrial appendage manipulation
A method for closure of the left atrial appendage (LAA), including: placing an LAA reshaper in contact with an LAA wall or near the LAA wall; invaginating at least a portion of the LAA into the left atrium (LA); reshaping by the LAA reshaper the LAA during the invagination; fastening the invaginated at least a portion of said LAA; and retracting the LAA reshaper from the LAA.

Plication systems, plication / spring systems, and methods of use thereof
Plicator systems may have two telescoping components that when arranged in an open configuration have one or more windows into which tissue of, for example, a tubular organ may be invaginated. The invaginated tissue may be secured in the window when the plicator system transitions to a closed configuration. Closing the window may act to, for example, clamp, pierce of the tubular organ tissue invaginated into the window, thereby securing the invaginated tubular organ tissue into the window. In some instances, an axially-expanding spring may be disposed between two plicator systems and when this assembly is implanted in a tubular organ, axial expansion of the spring may exert a distending force on the tubular organ, which may stimulate growth of the tubular organ.
