CATHETER DEVICES AND METHODS OF USE
20230191081 · 2023-06-22 ·

The disclosure includes a catheter comprising a proximal end, a distal end located opposite the proximal end, an outer surface extending between the proximal end and the distal end, and an inner surface located opposite the outer surface, wherein the inner surface is configured to also extend between the proximal end and the distal end. In some embodiments, each of the outer and inner surfaces is coated in a hydrophilic coating. The hydrophilic coating may be configured to reduce surface tension and increase the lubricity of the catheter.

A system of devices for treating an artery includes an arterial access sheath adapted to introduce an interventional catheter into an artery and an elongated dilator positionable within the internal lumen of the sheath body. The system also includes a catheter formed of an elongated catheter body sized and shaped to be introduced via a carotid artery access site into a common carotid artery through the internal lumen of the arterial access sheath. The catheter has an overall length and a distal most section length such that the distal most section can be positioned in an intracranial artery and at least a portion of the proximal most section is positioned in the common carotid artery during use.

Expandable tissue engagement apparatus and method

A system and associated method for manipulating tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders or other purposes. In one aspect, the system includes an expandable structure for enhancing engagement with median lobe prostate tissue.

FLUIDIC DEVICES, METHODS, AND SYSTEMS

Fluidic devices, methods, and systems are disclosed. One system may comprises a sheath, a delivery module, and a removal module. The sheath includes a working lumen, a delivery lumen, and a removal lumen. The delivery module is configured to move a fluid from a fluid reservoir and into a body cavity through the delivery lumen. The removal module is configured to move the fluid and a particulate contained therein out of the body cavity through the removal lumen, through a filtration device that removes the particulate, and back into the fluid reservoir. One method comprises placing a distal end of sheath into a body cavity, energizing the working lumen to generate a particulate in the cavity, moving the fluid into the cavity to engage the particulate, and moving the fluid and the contaminant from the body cavity, through a filter for removing the contaminant, and back into the fluid source.

Catheter for removing foreign body in blood vessel

A capturing unit provided on a distal end of a second tube can be deformed into a contracted state and an expanded state, in which the capturing unit is deployed to form a capturing chamber. The capturing chamber has an opening area decreased as it goes from a distal end opening of the capturing chamber toward a proximal end opening of the capturing chamber. A third tube rotatable relative to the second tube and a cutting unit provided on a distal end of the third tube for cutting a foreign substance are arranged in a second lumen. In the expanded state of the capturing unit, the cutting unit is arranged more toward the proximal end opening of the capturing chamber than the distal end opening.

RADIAL EXPANSION CONTROL MECHANISMS FOR INTRALUMINAL DEVICE

An intraluminal device and a method of removing a clot from a body lumen with an intraluminal device may be provided. The intraluminal device may include a hollow elongated shaft and a radially-expandable mesh segment situated distal to the elongated shaft. The elongated shaft may be secured relative to a first portion of the mesh segment. The intraluminal device may additionally include a core wire affixed to a second portion of the mesh segment and extending through the elongated shaft. The elongated shaft may be configured to radially expand the mesh segment by axially moving the first portion of the mesh segment relative to the second portion of the mesh segment. In addition, the core wire may be configured to radially expand the mesh segment by axially moving the second portion of the mesh segment relative to the first portion of the mesh segment.
