An example medical device for occluding the left atrial appendage includes an expandable member having a first end region, a second end region and an inflation cavity. The medical device also includes a plurality of spine members coupled to the expandable member, the plurality of spine members spaced circumferentially around an outer surface of the expandable member. Additionally, the medical device includes a valve member extending at least partially into the inflation cavity, wherein the plurality of spine members are configured to position the medical device within an opening of the left atrial appendage and wherein the expandable member is configured to expand and seal the opening of the left atrial appendage.

Occlusive device with expandable member

An example medical device for occluding the left atrial appendage is disclosed. The example medical device for occluding the left atrial appendage includes an expandable member having a first end region, a second end region and an inflation cavity. The example medical device includes at least one fixation member having a first end and a second end coupled to the expandable member. The at least one fixation member is configured to move from a delivery configuration to a deployed configuration in response to an expansion of the expandable member. Additionally, the example medical device includes a valve member extending at least partially into the inflation cavity and the expandable member is configured to expand and seal the opening of the left atrial appendage.

Occlusive device with actuatable fixation members

Delivery systems for liquid embolics and methods of using them are disclosed. The devices generally include a catheter and one or more retention elements to limit migration of the liquid embolic to non-target sites.

Systems and methods for delivery of gel embolics

A direct visualization catheter includes a handle, a balloon, an elongate shaft, and a camera assembly. The elongate shaft has a proximal end and a distal end opposite the proximal end. The proximal end is coupled to the handle. The distal end is coupled to the balloon and defines a longitudinal axis. The camera assembly is coupled to the distal end of the elongate shaft and is disposed within the balloon. The camera assembly includes a camera and an adjustment mechanism for varying a configuration of the camera relative to the distal end of the elongate shaft between a delivery configuration and a deployed configuration. The camera faces primarily in a radial direction in the delivery configuration and the camera faces primarily in an axial direction in the deployed configuration.

Direct visualization catheter and system

In some aspects, the present disclosure provides a delivery device for delivering a detachable medical implant that comprises an elongated delivery member and a first engagement portion. The first engagement portion comprises a first proximal-facing surface, a first distal-facing surface, and a first lumen that is configured to accommodate an activation wire, wherein at least 50% of a surface area of the first proximal-facing surface is angled away from a proximal end of the first engagement portion. In other aspects, the present disclosure provides a medical delivery system comprising: such a delivery device; an implantable device comprising a medical device portion and a second engagement portion, the second engagement portion comprising a second lumen configured to accommodate an activation wire, a second proximal-facing surface and a second distal-facing surface; and an activation wire. Other aspects pertain to methods of medical device delivery using such a medical delivery system.

Detachable implantable devices

Catheters with weeping balloons can be used for various medical purposes. For example, in some embodiments provided herein weeping balloons are used for catheter visualization devices. In some embodiments, weeping balloons are used to deliver therapeutic agents. Weeping balloons can include openings of a selected size and shape through which a fluid gradually flows or 'weeps.' The design of the openings can affect performance characteristics such as, but not limited to, fluid flow rate, tear resistance, and mitigation of counter-flow.

Weeping balloon devices

Expandable occlusive plugs and methods of using them are disclosed. The devices generally include a tubular body bearing multiple slits defining leaves, which expand radially outward when the ends of the device are brought toward one another.

Arterial-venous occlusion apparatus

Loading tools for use with medical devices are disclosed. An example loading tool may be suitable for use with a drug-coated expandable medical device. The loading tool may include a tubular sleeve having a distal end region, a proximal end region, and a lumen extending therethrough. The distal end region may include a reduced distal tip designed to interact with a hemostasis valve having a resilient seal member.

Additionally, the example medical device includes

An introducer sheath may include a tubular member comprising an inner layer and an outer layer coaxially disposed about a central longitudinal axis of the introducer sheath, the tubular member being configured to shift between an unexpanded configuration to an expanded configuration. The inner layer may be circumferentially discontinuous along at least a portion of its length. At least a first portion of the inner layer may be configured to move circumferentially relative to the outer layer when shifting between the unexpanded and expanded configurations.

Radially expandable introducer sheath

A hub assembly for connection to a medical device. The hub assembly may comprises an outer component having a proximal end, a distal end, and a cavity extending from the proximal end to the distal end. The hub assembly may further include an insert having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end positioned at least in part within the cavity of the outer component. The insert may have a lumen extending from the proximal end to the distal end thereof. The outer component may be formed from a first material and the insert may be formed from a second material different from the first material.

Catheter hubs

Described herein are delivery devices and systems for delivering a detachable medical device and various associated methods of using such devices and systems.

A hub assembly for connection to a medical device having a built in strain relief. The hub assembly may comprise a hub body having a proximal end and a distal end. A lumen may extend from the proximal end to the distal end of the hub body. The distal end of the hub body may have a rounded surface. The rounded surface may have a radius of curvature of greater than 1 millimeter.
