Abstract: 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.

Abstract: 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.

Abstract: A transport and delivery system which may be used for injectable materials such as radioactive injectables. The system includes a base configured to hold a material transport device containing the injectable material, and a cover including a material delivery system and a material access device. The cover is configured to be mated over the base to result in alignment of the material access device with the material transport device to allow the material delivery system to deliver the injectable materials from within the material transport device to a patient. A priming cap may be provided to facilitate priming of the material delivery system and material access device to be substantially airless.

Abstract: 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.

Abstract: The present invention provides systems and methods for accurately delivering embolic coils within a body lumen of a patient, as well as recapturing deployed embolic coils for removal or repositioning. In various embodiments, an embolic coil delivery system may include an elongate sheath with a lumen extending therethrough. An elongate shaft may be slidably disposed within the sheath. The shaft may comprise a split-distal end that defines an aperture. The split-distal end may be moveable between a contracted configuration and an expanded configuration. An embolic coil may include a proximal ball-tip that may be reversibly disposed within the aperture of the split-distal end.

Abstract: 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.
