20220331091 · 2022-10-20 · ·

Medical device for breast reconstruction for containing or integrating a breast implant, the device being designed for placement between the skin and the pectoralis major muscle and is configured to be sutured to the pectoralis major muscle. The device includes a container body having a half shell and a flat appendage joined continuously to a portion of the base of the half shell.

METHOD AND DEVICE FOR TRANSCATHETER TREATMENT OF AN ASCENDING AORTA ANEURYSM

An endoluminal prosthesis includes a stent-graft and a temporary aortic valve, typically combined in an integrated assembly suitable for transfemoral or other endoluminal placement in a patient's ascending aorta, aortic root, and aortic valve. The stent-graft has a base end configured to be positioned into over the patient's aortic root and over the aortic annulus. The temporary aortic valve assembly is attached to the base end of the stent-graft and comprises a scaffold configured to be anchored in the patient's aortic annulus and valve leaflets configured to function temporarily after the endoluminal prosthesis has been implanted. At least one fenestration suitable for receiving a guidewire and/or a coronary stent graft is located near a junction between the base end of the stent graft and the temporary aortic valve, wherein said at least one fenestration is disposed on the endoluminal prosthesis to be aligned with one of the patient's coronary ostia after the endoluminal prosthesis has been implanted.

Retrievable stent system

A system for treating a body lumen including a first stent configured to be positioned in a body lumen and a second stent configured to be positioned in the lumen of the first stent prior to removing the first stent from the body lumen. The first stent includes a liner disposed radially inward of the tubular scaffold of the first stent to permit tissue ingrowth within a tissue ingrowth region defined between the liner and the tubular scaffold. The retrieval stent is configured to be expanded within the previously implanted first stent to cause tissue to recede from the tissue ingrowth region to facilitate removal of the first stent from the body lumen.

Replacement mitral valves

A prosthetic mitral valve includes an anchor assembly, a strut frame, and a plurality of replacement leaflets secured to the annular strut frame. The anchor assembly includes a ventricular anchor, an atrial anchor, and a central portion therebetween. The ventricular anchor and the atrial anchor are configured to flare radially outwards relative to the central portion. The annular strut frame is disposed radially within the anchor assembly and is attached to the anchor assembly. The central portion is configured to align with a native valve orifice and the ventricular anchor and the atrial anchor are configured to compress native cardiac tissue therebetween.

Vascular shunt frame and vascular stent with improved apposition

A vascular shunt frame with improved apposition including a main body tube; at least one end of the main body tube is provided with a sealing covering; the sealing covering is provided with a main blood flow opening; a shaping component is disposed at the edge of the main blood flow opening. When the main body stent is inserted into the main blood flow opening of the main body tube, the shaping component can be closely attached to the outer surface of the main body stent, such that the sealing covering closely fits the outer surface of the main body stent to prevent endoleaks. The present disclosure also provides a vascular stent provided with an apposition-improved vascular shunt frame.

Transluminal delivery devices and related kits and methods

Prosthesis deployment devices are disclosed herein. In some embodiments, the prosthesis deployment device comprises an elongate delivery catheter assembly configured for electrosurgery and also configured to retain and deploy a prosthesis. Kits comprising the prosthesis deployment devices with a prosthesis loaded into a prosthesis pod of the device are disclosed herein as well as methods of using the prosthesis deployment devices.

System and method for reshaping heart

The present teachings provide systems, devices, and methods for reshaping the heart and reducing valve regurgitation. A device can be positioned proximate the heart and have a delivery profile and an inflated profile. The device can have a primary cavity and a secondary cavity, and an adhesive inside the secondary cavity. An injectable medium can be injected to the primary cavity of the device. As the primary cavity is filled, the adhesive is forced out of the secondary cavity to adhere the device. The inflated device can exert pressure on the heart, change the shape of a valve annulus, and allow a better coaptation of the valve leaflets.

STENTS AND METHODS FOR MANAGING PASSAGE OF MATERIAL THROUGH A BODY LUMEN

The present disclosure relates generally to stents and methods for managing passage of material through a body lumen. In some embodiments, a medical stent may include a stent body defined by a hollow tubular elongate structure extending along a central axis, the stent body including a first portion and a second portion. The medical stent may further include a control region between the first and second portions, wherein in a first configuration the hollow tubular elongate structure of the control region is in a closed, twisted configuration, and wherein in a second configuration the hollow tubular elongate structure of the control region is in an open, expanded configuration.

Thrombus management and structural compliance features for prosthetic heart valves

A prosthetic heart valve can include an outer support assembly, an inner valve assembly, which define between them an annular space, and a pocket closure that bounds the annular space to form a pocket in which thrombus can be formed and retained. Alternatively, or additionally, the outer support assembly and the inner valve assembly can be coupled at the ventricle ends of the outer support assembly and the inner valve assembly, with the outer support assembly being relatively more compliant in hoop compression in a central, annulus portion than at the ventricle end, so that the prosthetic valve can seat securely in the annulus while imposing minimal loads on the inner valve assembly that could degrade the performance of the valve leaflets.
