Ablation systems and methods of the present disclosure include a catheter including one or more image sensors. The one or more image sensors can facilitate, for example, positioning an ablation electrode at a treatment site of an anatomic structure and, additionally or alternatively, can facilitate controlling delivery of therapeutic energy to a treatment site of an anatomic structure.

DEPLOYING SPLIT-TIP HEMODIALYSIS CATHETER IN A RIGHT ATRIUM

A split-tip catheter and methods for deploying a split-tip catheter in a right atrium are provided. The catheter is configured with a distal potion including a first and a second distal end regions elastically divergable from alignment along a splitting plane to regain a relaxed configuration. The first distal end region terminates in a first tip having a first forward opening, and the second distal end region terminates in a second tip having a second forward opening. Catheter deployment may include directing the first forward opening generally towards an anterior right atrium wall portion and applying the first forward opening to withdraw blood from the right atrium.

20220233815 · 2022-07-28 · ·

The disclosure relates to a catheter, comprising: an elongated shaft body extending along a longitudinal axis and having a distal end portion connected to a catheter tip at a distal end of the catheter, wherein the shaft body comprises a first lumen extending along the longitudinal axis, and an optical fiber for measuring a force, wherein the optical fiber extends in the first lumen and comprises at least a first Bragg grating arranged in in the distal end portion of the shaft body. The distal end portion of the shaft body encloses at least a first stiffening element, wherein the first stiffening element extends along the longitudinal axis for stiffening the distal end portion of the shaft body.

Gas sampling catheters, systems and methods

Embodiments herein include gas sampling catheters, systems and related methods. In an embodiment, a gas sampling catheter is included. The catheter can include a catheter shaft having a proximal end and a distal end, the catheter shaft defining a lumen therein. The catheter can include a gas sampling port providing fluid communication between the exterior of the catheter shaft adjacent the distal end of the lumen of the catheter shaft. The catheter can further include a sensor element disposed in fluid communication with the lumen, the sensor element configured to detect a component of a gaseous sample. The sensor element can include a first measurement zone comprising a plurality of discrete binding detectors. Other embodiments are also included herein.

RADIOEMBOLIZATION DELIVERY DEVICE

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.

Drainage tube and treatment kit with drainage tube

Drainage tube for use in wound drainage, in particular in deep drainage, having a drainage lumen surrounded by a tube jacket and extending parallel to the tube axis, the tube jacket having at least one perforation which, starting at an outer boundary area of tube jacket, extends in a transverse direction, in particular approximately perpendicular to the tube axis, and opens out into the drainage lumen.

CATHETER FOR MONITORING PRESSURE

A catheter insertable into a patient for monitoring pressure having an expandable outer balloon. An expandable inner balloon is positioned within the lumen of the catheter and has having a second outer wall and forms a gas chamber to monitor pressure within the patient. In response to pressure exerted on the outer wall of the outer balloon, fluid within the outer balloon enters an opening in the wall of the catheter lumen to exert a pressure on the outer wall of the expanded inner balloon to deform the inner balloon and compress the gas within the inner balloon. A pressure sensor communicates with the gas containing chamber for measuring pressure based on compression of gas caused by deformation of the expanded inner balloon resulting from deformation of the expanded outer balloon.

NEUROASPIRATION CATHETER FOR THROMBECTOMY

Described herein is a neuroaspiration catheter for removing a blood clot in a blood vessel. The neuroaspiration catheter includes a first tube, a second tube and a wire for guiding the navigation of the catheter. The wire can be navigated to the site of the blood clot, aid the navigation of the catheter, and left in the blood vessel during and after the aspiration. If the aspiration fails, the catheter can be quickly navigated back to the site of the blood clot using the wire as a guide. Also described herein is a method of removing a blood clot using the neuroaspiration catheter.
