20220401241 · 2022-12-22 ·

A delivery system for delivering and deploying stent grafts having a proximal stent includes a first lumen and a stent capture device including a capture portion fixedly connected adjacent a first lumen distal end. An outer catheter has a catheter distal end and a catheter inner diameter. A second lumen having a second distal end is slidably disposed about the first lumen and within the outer catheter. A stent graft sheath has a sheath proximal end connected to the second distal end and disposed about the first lumen. The sheath has a sheath distal end and a sheath inner diameter greater than the catheter inner diameter for holding a compressed stent graft. A distal nose cone has a cone proximal end connected to either the capture portion or the first distal end. The nose cone and the capture portion are movably adjustable to selectively capture the sheath distal end therebetween.

Apparatus and methods for delivery, repositioning, and retrieval of transcatheter prosthetic valves

Apparatus and methods are described herein for use in the delivery and deployment of a prosthetic mitral valve into a heart. In some embodiments, an apparatus includes a catheter assembly, a valve holding tube and a handle assembly. The valve holding tube is releasably couplable to a proximal end portion of the catheter assembly and to a distal end portion of the handle assembly. The handle assembly includes a housing and a delivery rod. The delivery rod is configured to be actuated to move distally relative to the housing to move a prosthetic heart valve disposed within the valve holding tube out of the valve holding tube and distally within a lumen of the elongate sheath of the catheter assembly. The catheter assembly is configured to be actuated to move proximally relative to the housing such that the prosthetic valve is disposed outside of the lumen of the elongate sheath.

The disclosure relates to a stent assembly for placement of a stent within a ureter. In many embodiments, the stent assembly includes a band coupled to a proximal end of the stent. In many such embodiments, the band may extend into the urethra and facilitate removal of the catheter without the help of a medical professional or requiring a portion of the stent assembly (e.g., suture loop) to extend outside of the patient. In various embodiments, the band may include one or more features that promote patient comfort while the stent is positioned within a body, such as by being atraumatic and/or seamless.

Implant delivery system

A delivery system used for vascular implant delivery is described. In some embodiments, the delivery system includes a user-gripped handle used to aid in retracting and advancing an implant. In some embodiments, the delivery system includes a telescoping pusher system to aid in retracting and advancing an implant.

TRANSLUMINAL ANGIOPLASTY DEVICES AND METHODS OF USE
20220378592 · 2022-12-01 ·

A percutaneous transluminal angioplasty device includes a catheter defining one or more lumens. A filter is coupled to the catheter adjacent a distal end of the catheter, and the filter is movable between an unexpanded and expanded configuration via a filter activation wire that extends through a lumen. An expandable balloon is coupled to the catheter proximally of the filter, and a stent is disposed over at least a portion of the balloon. To deploy the stent to a target site, the filter is first moved into its expanded position via the filter activation wire. Then, the stent is expanded, and the balloon is inflated to expand the stent further radially. The balloon is then deflated, the filter is contracted, and the catheter, balloon, and filter are removed from the body.
