A catheter () comprises a jacket () and defining a lumen, and extends distally towards a tip (). The catheter has a helical support () within the jacket for at least some of the length of the jacket. The catheter distal end has a plurality of portions of different configurations for different bending and/or pushability characteristics. These may be according to different helical supports and the manner in which they are interwoven, and/or different liners with lap joints. There may be a hydrophilic coating.

Corrugated catheters

Medical devices and methods for closing an anatomical aperture in a tissue are disclosed. The medical devices can include distal and proximal support structures, which can include a plurality of anchor members. A connection element can connect the distal and proximal support structures, and be configured to twist to create a seal within the medical device. In certain embodiments, a sheath about the medical device can be retracted to expose the distal support structure, which can allow it to revert to an anchoring configuration from a delivery configuration, such that the anchor members can engage an interior surface of the tissue. After twisting the connection element to form a seal, the sheath can be further retracted to expose the proximal support structure, which can allow it to revert to an anchoring configuration from a delivery configuration, such that the anchor members can engage an exterior surface of the tissue.
