20230233228 · 2023-07-27 · ·

Systems, devices, and methods for providing access to the heart. The system includes an intracardiac access device comprising an elongate member having a channel extending between a distal end and a proximal end thereof. The intracardiac access device is configured to be advanced through an extrapericardial penetration in the left atrial wall without penetrating the pericardium of the heart. An optional procedural device is configured to be advanced through the channel of the intracardiac access device into an internal chamber of the heart and configured to perform a surgical procedure in the internal chamber of the heart. A working channel of an optional suprasternal access device is configured to facilitate access of the intracardiac access device into the body of the patient by providing a path from a suprasternal opening to a position adjacent the roof of the left atrium.

CLOSURE APPARATUS WITH FLEXIBLE SEALABLE MEMBER AND FLEXIBLE SUPPORT MEMBER

The disclosed technology provides a device for sealing an aperture in a tissue of a body lumen. The device comprises a flexible support member having a base having (i) a central portion and (ii) one or more lateral support portions, to engage and/or hold a sealable member of the device against an interior surface of the tissue when the device is in the sealing position. The lateral support portions provide additional support surfaces to engage peripheral portions of the sealable member against the interior surface of the tissue.

20230000359 · 2023-01-05 ·

A system may comprise a first catheter having a first steerable segment and a second catheter disposed within the first catheter. The second catheter may have a second steerable segment. The system may also comprise an imaging element supported at a distal end of the second catheter, a coil reference sensor supported at a distal portion of the second catheter, and a processor in electrical communication with the coil reference sensor. The processor may be configured to determine a position of a distal portion of the first catheter with reference to the coil reference sensor.

Sealing device and delivery system

The invention relates to a sealing device for repair of cardiac and vascular defects or tissue opening such as a patent foramen ovale (PFO) or shunt in the heart, the vascular system, etc. and particularly provides an occluder device and trans-catheter occluder delivery system. The sealing device would have improved conformity to heart anatomy and be easily deployed, repositioned, and retrieved at the opening site.

Delivery systems for control of gastrointestinal bleeding

The present disclosure relates to a gastrointestinal delivery device of a dressing, where the delivery device is capable of fitting through a narrow channel before expanding and applying the dressing. The gastrointestinal delivery device may be used in all gastrointestinal bleeding applications and can be used with a biocompatible, foldable, thin profile, chitosan dressing. Various aspects of the device and its uses are provided herein.

Endovascular apparatus for perfusing organs in a body

In one representative embodiment, a method of perfusing organs in a patient's body is provided. The method comprises isolating the visceral arteries and the visceral veins from blood circulating through the patient's heart and perfusing the visceral arteries, the visceral veins, and the abdominal organs with a perfusion fluid that is fluidly separated from the blood circulating through the patient's heart. While the visceral arteries and the visceral veins are isolated, and the visceral arteries, the visceral veins, and the abdominal organs are being perfused, the patient's blood is allowed to continue to circulate through the heart.

Deflectable torque cable for delivery of medical devices

A delivery cable for delivering a medical device and a delivery device including the same are described herein. The delivery cable includes a flexible inner core, an outer coil surrounding at least a portion of the flexible inner core, and a pull wire disposed between the flexible inner core and the outer coil, the pull wire configured to deflect a distal deflectable portion of the delivery cable upon manipulation thereof. Methods of making the delivery cable and methods of using the delivery cable to deploy a medical device are also described herein.

System Comprising an Elongated Catheter and an Implant Detachably Attached to a Distal End of the Elongated Catheter

A system includes an elongated catheter including a proximal end configured for operative coupling to an electrical power source, a distal end with a first electrical connector and a first conducting wire, an implant including a tissue energising module and a proximal connecting hub configured to detachably couple with the distal end of the elongated catheter. The proximal connecting hub includes a second electrical connector configured to mate with the first electrical connector and electrically couple the first electrical connector with the tissue energising module through a second conducting wire. A latch system to lock the distal end of the catheter to the proximal connecting hub arm includes an arm attached to the distal end of the catheter that is resiliently deformable such that the arm engages a sidewall of the proximal connecting hub and a locking element that is axially adjustable.
