An endovascular apparatus, including an elongated catheter having an inner lumen extending therethrough; a balloon affixed to the catheter for expansion into the inner lumen of the catheter when the balloon is inflated; and a tube secured relative to the balloon, wherein the tube is configured to enable selective inflation and deflation of the balloon, and wherein an outer diameter of a portion of the catheter adjacent the balloon is substantially the same when the balloon is inflated and when the balloon is deflated.

Modular pre-loaded implant subassemblies that can be packaged separately from a handle, which allows using any one of a plurality of separately packaged modular pre-loaded implants with a common handle.

A detachment system configured to deliver an implantable medical device to a target location of a body vessel includes a generally hollow distal tube and an engagement system. The distal tube can have an inner lumen having a first diameter therethrough and a narrowed portion positioned on at least a portion of the distal tube and having a second diameter lesser than the first diameter. The engagement system can be slidably disposed within the inner lumen and have a detachment feature connected to the implantable medical device and a locking member engaging the detachment feature and interfacing with the narrowed portion of the distal tube. The locking member is configured to deploy the implantable medical device when the locking member is displaced from the narrowed portion of the distal tube.

An apparatus for treating an aneurysm in a blood vessel includes a wire to be advanced within a tube and an occlusion element disposed on the wire. The occlusion element includes a cover and an inner anchoring member. The occlusion element is configured to fit within the tube and slide out of an opening at distal end of the tube in response to movement of the wire. The cover is configured to expand to an expanded configuration when advanced into the aneurysm, wherein the cover comprises a diameter that is greater than the diameter of a neck portion of the aneurysm and is configured such that a first portion of the cover contacts an interior surface of the aneurysm and a second portion covers the neck portion of the aneurysm. The inner anchoring member extends from the cover portion and is configured to contact the interior surface of the aneurysm.

The present disclosure relates to a self-expanding braided implant, including a distal implant end and a proximal implant end, the braided implant being invertible about the distal implant end. Translation of the braided implant distally causes the braided implant to invert and fold into itself thereby forming an occlusive sack configured to occlude the aneurysm.

A medical device system may include an elongate shaft having a lumen extending to a distal end of the elongate shaft, wherein a proximal portion of the elongate shaft is configured to disengage from a distal portion of the elongate shaft; a medical device disposed proximate the distal end of the elongate shaft; a release wire disposed within the lumen of the elongate shaft, wherein the release wire releasably attaches the medical device to the distal end of the elongate shaft; and an introducer sheath slidably disposed over the elongate shaft, wherein the introducer sheath is configured to disengage the proximal portion of the elongate shaft from the distal portion of the elongate shaft.

Treatment of aneurysms can be improved by delivering an occlusive member (e.g., an expandable braid) to an aneurysm sac in conjunction with an embolic element (e.g., coils, embolic material). A delivery system for such treatment can include an occlusive member configured to be positioned within an aneurysm sac and having a proximal hub. An elongate tubular member has an engagement member removably coupled to the proximal hub, for example via threaded engagement or an interference fit via one or more engagement members. A conduit extending within or adjacent to the elongated member is configured to receive an embolic element therethrough for delivery to the aneurysm sac.

Devices, systems, and methods for treating vascular defects are disclosed herein. One aspect of the present technology, for example, includes an occlusive device comprising a mesh having a low-profile state for intravascular delivery to the aneurysm and a deployed state. The mesh may comprise an expandable cage formed of a plurality of mesh stmts. In some embodiments, the cage is configured to receive an embolic material therein.

Delivery and detachment system for an implantable intravascular treatment device, the system including an outer delivery tube and a proximal inner tube telescopically slidable within the lumen of the outer delivery tube. The proximal inner tube has a weld window radially inward cutout defined therein along an axial section between the proximal and distal ends. A securement wire disposed axially within the lumen of the proximal inner tube is secured to an inner wall of the lumen of the proximal inner tube via at least one supplemental connection point coinciding with the weld window. Also, the method for making the delivery and detachment system wherein one or more positioning wires threaded through the lumen of the proximal inner tube are manipulated to force the securement wire and the proximal inner tube in direct physical contact with one another along an axial section coinciding with the weld window.

A delivery system for delivering and deploying an implantable medical device is presented that includes a delivery member having a flexible distal portion. The deliver member can include a proximal hypotube, a flexible coil extending distally from the proximal hypotube, a compressible distal hypotube extending distally from the flexible coil, a sleeve extending along the flexible coil, and a loop wire. The loop wire can be effective to inhibit longitudinal elongation of the flexible coil. The sleeve can be effective to inhibit radial expansion of the flexible coil.
