Medical device delivery devices, systems, and methods are disclosed herein. According to some embodiments, a medical device delivery system includes a core member and a coupling assembly positioned about the core member. The coupling assembly may include an engagement member having projections configured to engage a medical device and a release member that is movable between a compressed configuration and an expanded configuration. A medical device can extend along the core member such that, when the release member is in the compressed configuration, the projections of the engagement member engage the medical device and when the release member is in the expanded configuration, the release member prevents the projections from engaging the medical device and/or facilitates expansion of the medical device.

Medical device delivery devices, systems, and methods

Devices for treating vascular defects and associated systems and methods are disclosed herein. In some embodiments, an occlusive device for treating an aneurysm includes an anchor structure extending circumferentially around an opening. A plurality of spiral struts are coupled to the anchor structure and extend over the opening, and a plurality of protrusions extend away from the spiral struts. The spiral struts and the protrusions can both be arranged within a common plane when the occlusive device is in an expanded configuration. When the occlusive device is deployed within the aneurysm and in the expanded configuration, the spiral struts can span the neck of the aneurysm, and the anchor structure can engage the wall of the aneurysm near the neck.

Occlusive devices with spiral struts for treating vascular defects

Methods for restoring blood flow in occluded blood vessels using an apparatus having a self-expandable distal segment that is pre-formed to assume a superimposed structure in an unconstrained condition but can be made to take on a volume-reduced form making it possible to introduce it with a microcatheter and a push wire arranged at the proximal end, with the distal segment in its superimposed structure assuming the form of a longitudinally open tube and having a mesh structure of interconnected strings or filaments or struts. In a preferred embodiment, the distal segment has a tapering structure at its proximal end where the strings or filaments or struts converge at a connection point.

Methods and apparatus for flow restoration

Devices for treating vascular defects and associated systems and methods are disclosed herein. In some embodiments, for example, an occlusive device for treating an aneurysm includes a tubular structure having a first end portion with a first opening, a second end portion with a second opening, and a mesh surface extending between the first and second end portions. The occlusive device also includes a plurality of spiral struts coupled to the first end portion of the tubular structure and extending over the first opening. When the occlusive device is deployed within the aneurysm, the tubular structure and the plurality of spiral struts can be configured to self-expand such that the plurality of spiral struts span a neck of the aneurysm substantially within a single plane and the mesh surface of the tubular structure engages a wall of the aneurysm near the neck.

Expandable devices for occluding bifurcation aneurysms are disclosed herein. Several of the embodiments are directed towards an expandable device comprising a mesh configured to be deployed at a treatment site including blood vessel bifurcation of a human patient so that the mesh extends across a neck of an aneurysm and prevents or limits blood flow through the mesh and into the aneurysm. The mesh can comprise one or more circumferentially discontinuous portions so that, when the device is deployed at the treatment site, the device does not substantially impede flow from a parent blood vessel to two or more branching blood vessels. Systems and methods for delivering an expandable device of the present technology are also disclosed herein.

Expandable devices and associated systems and methods

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 treatment system for such treatment can include an electrolytically corrodible core wire having a proximal portion, a distal portion, and a detachment zone between the proximal portion and the distal portion. An occlusive member having a proximal hub is coupled to the core wire distal portion. A conduit extends along at least a portion of the core wire. The conduit has a lumen configured to pass an embolic element therethrough.

Systems and methods for treating aneurysms

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.

Inflation devices for inflating intragastric devices and associated systems and methods are disclosed herein. In several embodiments, an inflation device can include a tube, an inner detent, and an outer detent. The tube can extend from a proximal portion of the inflation device to a distal portion of the inflation device, and can include a handle at the proximal portion and a barb at the distal portion. The barb can have a cross-sectional dimension greater than a cross-sectional dimension of a corresponding inflation port of an intragastric device. The inner detent can be positioned over the barb and can include a mating interface. The outer detent can be positioned over the inner detent, and can be configured to attach over a proximal cap of the intragastric device. The tube can be longitudinally advanceable relative to at least one of the inner and outer detents.

Inflation devices for intragastric devices with improved attachment and detachment and associated systems and methods

A deflation catheter device, comprising: a catheter tube having a proximal end and a distal end; a stylet disposed within the catheter tube; a stylet handle attached to the stylet; and a y-connector disposed near a proximal end of the catheter tube, configured to provide fluid communication from the distal end of the catheter tube and a suction port, and configured to provide access for the stylet from the proximal end of the catheter tube to the distal end of the catheter tube.

Deflation and removal of implantable medical devices

The present disclosure is a method and apparatus to prepare a tissue tract having a handle member with a centerline, and a scalpel member fixedly attached to the handle member having a blunt tip, wherein the handle member has a first side positioned at a first positive angle relative to the centerline, and a second side opposite the first side positioned at a second positive angle relative to the centerline.

Tissue tract lancet

A sealing device attached to an intragastric balloon device having a head flexibly attached to a body by a pivot portion, where the pivot portion provides the head with a closed state and an open state relative to the body and the intragastric device. The sealing device having one or more plugs configured to seal an aspiration port of a lumen when the head is in a closed state and further configured to release the aspiration port of the lumen when the head is in an open state.

Enhanced explant processes and mechanisms for intragastric devices

A sealing device attached to an intragastric balloon device having a at least one flexible membrane aligned with and configured to seal an aspiration port of a lumen when the membrane is in a closed state and further configured to provide access to the lumen when the membrane is in a open state.
