A catheter is provided which includes an outer catheter and an extendable inner catheter. A sealing feature is positioned between the inner catheter and the outer catheter to seal the annular gap between the two while allowing axial translation. The seal may be a compliant protrusion surrounding the inner catheter and may have a chevron-shape for facilitating axial translation. The seal may be a one-way valve configured to allow antegrade flushing but prevent retrograde flow. The seal may be squeegee-like flange on the distal tip of the outer catheter. The seal may be an expandable bulge, which may be mechanically expandable or inflatable or which may be a photosensitive or electrosensitive hydrogel. The seal may include a spring that is radially compressed upon translation or rotation of the inner catheter to transiently break the seal. Also provided is a seal for sealing between the catheter and the vasculature.

According to an embodiment, an embolic apparatus includes: a main body portion extending in a longitudinal direction; a plurality of first frame portions foldably connected to the main body portion; a plurality of second frame portions foldably connected to an end opposite to the other end of the main body portion connected to the plurality of first frame portions; and a blocking film portion connecting the plurality of first frame portions and covering the first frame portion, wherein the first frame portion and the second frame portion extend in directions away from each other.

An medical implantable occlusion device (100) is disclosed having a collapsed state and an expanded state and comprising a braiding (101) of at least one thread, and a distal end (102) comprised of said braiding. The distal end comprises loops (103, 104, 204, 304) formed by loop strands (105, 106, 206, 306) of the at least one thread, wherein, at least in said expanded state, each loop strand has a curved shape and extends away from a centre point (117) of the distal end, whereby an apex point (107, 108, 208, 308) of each of the loop strands corresponds to the turning point of the curved shape and to the point of each of the loop strands being arranged closest to the centre point. At least one of the loop strands is displaced from the centre point by a centre distance (109, 110, 210, 310), and the apex point lie at a distance from a periphery (113) of the distal end.

A ventricular partitioning device for isolating damaged tissue within a ventricle of the heart is disclosed. The ventricular partitioning device includes a disk-shaped portion configured to isolate a portion of a ventricular wall to facilitate remodeling of the ventricular wall. The device further includes an anchor configured to secure the device to the ventricular wall.

An occlusion device (210) is provided for occluding a left atrial appendage (LAA), including a compliant balloon (230) defining a fluid-tight balloon chamber (232), and an actuating shaft (234), which is disposed at least partially within the balloon chamber (232) for setting a distance between distal and proximal end portions (236, 238) of the balloon (230). A proximal LAA-orifice cover (70) includes a frame (72) and a covering (74) fixed to the frame (72). An orifice-support stent (290) is fixed to and extends distally from the proximal LAA-orifice cover (70), and is generally cylindrical when in a radially-expanded state. Other embodiments are also described.

A vaso-occlusive device, includes: a vaso-occlusive structure configured for implantation in an aneurysm sac, the vaso-occlusive structure having a delivery configuration when restrained within a delivery catheter and having a deployed configuration when released from the delivery catheter into the aneurysmal sac, at least a portion of the vaso-occlusive structure being composed of a AuPtW (gold-platinum-tungsten) alloy; wherein the AuPtW alloy comprises platinum within a range between 25% and 40% by weight, and wherein the AuPtW alloy comprises tungsten within a range between 0.01% and 10% by weight.

A pulmonary artery flow restrictor system includes a funnel shaped membrane with a proximal base, a restrictive distal opening which is stretchable to larger sizes, an internal strut structure, and an external stent structure.

A bronchial stent includes a first branch configured to widen, open, and/or mechanically support a first airway; an obstructive portion that, when the stent is deployed in the first airway, obstructs a second airway, the second airway forming a branching connection with the first airway; and a feature proximal to the obstructive portion, the feature configured to facilitate opening of the obstructive portion.

The present disclosure relates to delivery devices and interventional devices configured to enable monitoring of pressure and other hemodynamic properties before, during, and/or after a cardiac procedure. A guide catheter includes a routing lumen or a routing groove for routing a sensor wire to a desired location during a cardiac procedure. A guide catheter includes one or more pressure sensors positioned to provide desired pressure measurements when the guide catheter is deploying an interventional device. An interventional device may also include one or more associated sensors for providing hemodynamic information before, during, and/or after deployment.

A deployable occlusion device for filling an aneurysm. The occlusion device includes a support structure, for example a wire or otherwise elongate structure. The occlusion device also includes a mesh component having a porosity. The mesh component has a first end portion and a second end portion. The first end portion of the mesh component is attached to the support structure and the second end portion of the mesh component is a free end. The mesh component extends from the support structure.
