Stent graft transport device
11786387 · 2023-10-17 · ·

A stent graft transport device includes a mounted state keeping wire that keeps a mounted state of a stent graft on a transport tube or a contracted state keeping wire that keeps a contracted state of the stent graft. The transport tube can be separated from the stent graft by pulling an operation end part of the mounted state keeping wire, and the stent graft can be in an expanded state by pulling an operation end part of the contracted state keeping wire. Furthermore, the operation end part of each of the wires is housed inside the transport tube. In order to draw the operation end part, a wire pulling-out string is provided, one end part of which is mounted on the mounted state keeping wire and the other end part of which is pulled out from a window arranged on a side peripheral surface of the transport tube.

A SCAFFOLD FOR A TUBE
20230310140 · 2023-10-05 ·

A scaffold for a tube, the scaffold having a membrane and a pair of splines integrally formed with or embedded in the membrane. The splines being spaced apart from one another with the membrane spanning therebetween and with the membrane further having a pair of grooves disposed between the splines adapted to receive the splines when the membrane is folded over on itself. The scaffold may be applied internally or externally to a tube, including tubular biological structures (e.g.. arteries) to provide support thereto, and in this sense, it may be used as a stent. The scaffold is more easily deployed and retrieved than known stents,

Highly flexible stent

A stent includes wavy-line pattern bodies having a wavy-line pattern and arranged side-by-side in an axial direction LD, and coiled elements arranged between the wavy-line pattern bodies adjacent and extending in a spiral manner around an axis. All apices on opposite sides of the wavy-line pattern of the wavy-line pattern bodies that are adjacent are connected by way of the coiled element. When viewing in a radial direction RD, a circular direction CD of the wavy-line pattern bodies is inclined with respect to the radial direction RD, and a winding direction of one of the coiled elements located at one side in the axial direction LD with respect to the wavy-line pattern bodies and a winding direction of one other of the coiled elements located at the other side in the axial direction LD are opposite.

Cinch device and method for deployment of a side-delivered prosthetic heart valve in a native annulus

The invention relates to anchor channels and subannular anchors for a transcatheter heart valve replacement (A61F2/2412), and in particular for an orthogonally delivered transcatheter prosthetic heart valve having a annular support frame having compressible wire cells that facilitate rolling and folding the valve length-wise, or orthogonally to the central axis of the flow control component, allowing a very large diameter valve to be delivered and deployed to the tricuspid valve from the inferior vena cava or superior vena cava, or trans-atrially to the mitral valve, the valve having a height of about 5-60 mm and a diameter of about 25-80 mm, without requiring an oversized diameter catheter and without requiring delivery and deployment from a catheter at an acute angle of approach.

LOADING APPARATUS AND SYSTEM FOR EXPANDABLE INTRALUMINAL MEDICAL DEVICES

Medical device loading apparatuses, systems, methods and kits are described. A loading apparatus comprises a main body having a passageway. The passageway has a first inner diameter, a second inner diameter, and a transition chamber. An expandable intraluminal medical device can be loaded into a delivery catheter using the loading apparatus by placing the device into the passageway and pushing the device along an axial path.

Expandable support frame and medical device

Support frames and medical devices are described. An example medical device comprises an expandable support frame with first and second leaflets attached to the support frame. Each of the first and second leaflets defines a domed radius that is equal to or less than the radius of the expandable support frame when the expandable support frame is in an expanded configuration and the leaflets are subjected to fluid pressure sufficient to affect closure of the valve orifice.

Acute and chronic devices for modifying flow in body lumens and methods of use thereof

The acute and chronic devices and methods described herein include a body lumen fluid flow modulator including an upstream flow accelerator and a downstream flow decelerator. The fluid flow modulator preferably includes one or more openings that define a gap/entrainment region that provides a pathway through which additional fluid from a branch lumen(s) is entrained into the fluid stream flowing from the upstream flow accelerator to the downstream flow decelerator. Delivery devices including a sheath and inner assembly also are provided for delivering the flow modulator to the body lumen. The delivery device may maintain the flow modulator in its collapsed, delivery state upon retraction of the sheath for ease of readjustment within the body lumen prior to full deployment of the flow modulator within the body lumen.
