Apparatus and associated methods relate to a flexible extrusion having a number of radially extending members configured for slidable insertion into a lumen of a surgical catheter shaft. In an illustrative example, the extrusion may have a flexible wall and define an interior insert lumen extending along the longitudinal axis from a proximal end to a distal end. Each of the radially extending members may have a distal engaging surface. When the extrusion is slidably inserted, for example, into the lumen of the catheter shaft, the distal engaging surface of each of the plurality of radial extending members may slidably engage an interior surface of the catheter shaft. In some examples, the inserted extrusion may define an annular distribution of longitudinally extending channels between a proximal and a distal end of the catheter. The slidable construction may advantageously simplify assembly, for example. The channels may offer end-to-end communication.

A steerable catheter comprises a transducer that is situated at a flexible distal end, and is coupled to the handle of the catheter via an insertion tube. The flexible distal end is controlled by a plurality of articulation pull-cables that extend from an articulation control device in the handle to the far end of the distal end, such that when one articulation pull-cable is pulled, and the opposing articulation pull-cable is slackened, the flexible distal end bends in the direction of the tensioned articulation pull-cable. To minimize pull-resistance over time, while still providing insertion-tube flexibility, inserts having pull-cable lumens are situated in the insertion tube to isolate each articulation pull-cable from each other, and from other cables that couple the transducer to the handle.

A delivery assembly includes a console including a vial containment region and a vial engagement mechanism extending from the console within the vial containment region. The engagement mechanism is configured to engage a vial assembly. The delivery assembly further includes a sled assembly removably coupled to the console at the vial containment region and a safety shield removably coupled to the console over the vial containment region such that the vial engagement mechanism and the sled assembly are encapsulated within the safety shield when the safety shield is coupled thereto. The sled assembly, the vial assembly, and the safety shield are configured to inhibit radioactive emissions from within the vial containment region.

A system for determining orientation of a distal end of a catheter. The system includes a radial ultrasound system configured to generate images based on data received from a radial ultrasound probe. The system also includes a display device to present the generated images, a medical device, and a catheter system. The catheter system includes a flexible shaft having a first lumen configured to receive the radial ultrasound probe and a second lumen configured to receive the medical device, a cap portion having a longitudinal axis, and at least one orientation pin. The cap portion includes a third lumen configured to align with the first lumen, a fourth lumen configured to align with the second lumen, an exit port, and a ramp disposed between the fourth lumen and the exit port.

A device has a drainage conduit for draining fluids from a patient. The drainage conduit may be flexible. One or more flexible delivery conduits deliver medication to the patient. The one or more flexible delivery conduits are attached to the flexible drainage conduit. The one or more flexible delivery conduits are detachable from the flexible drainage conduits at at-least one end of the drainage conduit so that the delivery conduits can be peeled off the drainage conduit at the proximal and deployed with the proximal ends of the delivery conduits separated from the proximal end of the drainage conduit.

The illustrative embodiments described herein are directed to systems, methods, and apparatuses for applying a reduced pressure to a subcutaneous tissue site. In one instance, a manifold for applying reduced pressure to a subcutaneous tissue site includes a plurality of first conduits, each of the plurality of first conduits having a wall with at least one first aperture and at least one second aperture. At least one of the plurality of first conduits is operable to deliver reduced pressure to the subcutaneous tissue site. The plurality of first conduits is coupled in a spaced arrangement that forms an interior space. The manifold further includes a second conduit comprising the interior space and formed by a portion of each wall of the plurality of first conduits. The second conduit is in fluid communication with the plurality of first conduits via the at least one second aperture.

Medical instruments and systems for applying energy to tissue, and more particularly relates to a system for ablating, sealing, coagulating, shrinking or creating lesions in tissue by means of contacting a targeted tissue in a patient with a vapor phase media wherein a subsequent vapor-to-liquid phase change of the media applies thermal energy to the tissue to cause an intended therapeutic effect. Devices and methods for generating a flow of high-quality vapor and monitoring the vapor flow for various parameters with one or more sensors. Devices and methods for modulating parameters of the system in response to the observed parameters

A device for providing access to a nodule, lesion, or pathological area in a lung or other body organ or lumen. The device includes a sheath portion having a proximal end and a distal end and a plurality of stabilization wires. The sheath portion includes a primary lumen that extends from the proximal end to the distal end and a plurality of secondary lumens that extend from the proximal end to the distal end. The stabilization wires are configured to be slidably received within the secondary lumens. The length of the stabilization wires is greater than the length of the secondary lumens.

An apparatus and method for preventing stroke by occluding blood flow through the carotid arteries and a left subclavian artery of a patient is provided. The apparatus has a first occluding catheter that carries a first occluding balloon that has an inflated configuration that occludes one of the carotid arteries. The apparatus also includes a second occluding catheter that carries a second occluding balloon that has an inflated configuration that occludes the other one of the carotid arteries. A third occluding balloon is present, that could be on an insertion device, that may occlude the left subclavian artery.

Elongate medical devices with a deflectable shaft section include a lumen liner configured to enhance planarity control of the deflectable shaft section. An elongate medical device includes a deflectable shaft section, a lumen within the deflectable shaft section, and a lumen liner that surrounds and defines the lumen. The lumen liner has an in-plane bending stiffness and an out-of-plane bending stiffness that is greater than the in-plane bending stiffness to provide planarity control of the deflectable shaft section during the cross-sectional bending of the deflectable shaft section.
