A personalized prosthesis for implantation at a treatment site of a patient includes a self-expanding mesh or membrane having collapsed and expanded configurations. The collapsed configuration is adapted to be delivered to the treatment site, and the expanded configuration engages the personalized prosthesis with the treatment site. The mesh or membrane is personalized to match the treatment site in the expanded configuration, and has an outer surface that substantially matches the treatment site shape and size. The self-expanding mesh or membrane forms a central lumen configured to allow blood or other body fluids to flow therethrough. Methods of manufacturing and delivery of the personalized prosthesis are also disclosed.

An implantable device includes an outer tubular member defining a longitudinal axis and a lumen. The outer tubular member includes: an outer wall portion having a plurality of first strands defining a plurality of first openings therebetween, the outer wall portion having a first porosity; and an inner baffle portion disposed within the lumen, the inner baffle portion including a plurality of second strands defining a plurality of second openings therebetween, the inner baffle portion having a second porosity that is lower than the first porosity of the outer wall portion.

The present invention relates to a stent-graft system comprising a first hollow cylindrical stent-graft body and at least one second hollow cylindrical stent-graft body. The first and the second stent-graft bodies are two structurally separate stent-graft bodies, and each comprise a first end, a second end, and a longitudinal axis. The first and the second stent-graft bodies further each comprise a stent-graft portion and a stent portion. The stent portion of the first stent-graft body and the stent portion of the second stent-graft body are designed in such a way that they can be at least partially inserted into one another in order to form one shared stent portion which is free from prosthesis material.

An intraluminal stent (1) and a preparation method therefor are provided. The intraluminal stent (1) includes at least one sub-stent. The sub-stent includes at least a first wire (4) extending along a first spiral direction and at least a second wire (5) extending along a second spiral direction, and the first wire (4) and the second wire (5) extend in different directions to form several wire intersection points. The intraluminal stent (1) has several wrapped portions (2) to wrap two corresponding wire tail ends. A wrapping connector (3) is disposed at a periphery of the wrapped portion (2). Two end portions of the wrapping connector (3) are firmly connected to regions corresponding to two ends of the wrapped portion (2). The two wire tail ends of the wrapped portions (2) are wrapped by using the wrapping connector (3). The stent (1) is less harmful to intraluminal tissues and a relatively strong tensile resistance.

A prosthetic assembly for repairing a target tissue defect within a target vessel region configured includes an exclusion structure sized to substantially bypass target tissue defect, and includes a branch assembly. The branch assembly can include a self-expanding outer branch prosthesis having an inflow region configured to deform to a non-circular cross-sectional-shape when deployed, and a support structure at least partially disposed within the inflow region. The support structure preserves blood flow to the branch vessel while the deformed inflow region inhibits blood leakage between and/or around the prosthetic assembly.

A self-expanding braided stent includes at least a distal radial expansion ring added to a distal end of the stent body to increase a radial expansion force of the self-expanding braided stent in deployment of the stent, and to facilitate advancement of the stent through a delivery sheath by a core advancement wire. A proximal radial expansion ring is optionally added to a proximal end of the stent body to allow the stent to be recaptured following partial deployment by retraction of the core advancement wire, prior to full deployment of a proximal portion of the stent body.

A stent-delivery assembly that includes a catheter; an expandable stent that is movable, relative to the catheter, from a first position to a second position; and a guidewire assembly extending through a longitudinal passage of the catheter and a longitudinal passage of the stent, the guidewire assembly being movable, relative to the catheter, from a third position to a fourth position. While the expandable stent is in the first position and while the guidewire assembly is in the third position, the stent-delivery assembly has an a-traumatic shape. While the expandable stent is in the second position and while the guidewire assembly is in the fourth position, the guidewire assembly is capable of passing through the stent to allow for retrieval of the stent-delivery assembly. Methods of use and manufacture are also included.
