摘要:
The present invention refers to medical devices comprising a non-metallic micro tube containing FRP (fiber reinforced polymer), especially to respective tubings, used for constructing catheters like balloon dilation catheters, stent delivery catheters, guiding catheters and diagnostic catheters.
摘要:
The present invention relates to a stent delivery system and a process for mounting a stent onto a delivery system. More specifically, the present invention relates to a method of loading a stent onto a balloon and mounting the stent balloon assembly onto a catheter. The premounting of the stent onto the balloon subassembly allows the stent to be crimped in a way that the crimping recoil can be compensated and stent retention is kept at a maximum.
摘要:
The invention relates to a stent graft comprising a first expandable stent (10; 16) having a tubular wall (11), and a tissue graft (15) disposed around the outside of the tubular wall (11), wherein the outside of the tubular wall (11) is rougher at longitudinal end portions of the first stent (10; 16) compared to a center portion located in between the longitudinal end portions. Further, the invention relates to a method of manufacturing such a stent graft.

The invention relates to a stent graft (1) comprising an inner expandable stent (2; 12) having a tubular wall; an outer expandable stent (3; 13) having a tubular wall and being arranged coaxial around the inner stent (2; 12), the outer stent (3; 13) having a different length as the inner stent (2; 12) in a state of equal stent expansion; a tissue graft (4) disposed coaxial to and entirely in between the inner and outer stent (2, 3; 12, 13), the tissue graft (4) having the same length as the shorter one of the inner and outer stent, wherein the longitudinal centers of the outer stent (3; 13) and the tissue graft (4) are aligned with the longitudinal center of the inner stent (2; 12).
摘要:
An interluminal medical treatment device (100) configured to treat a targeted treatment site within a body lumen (190). The interluminal medical treatment device can include an elongated generally tubular outer member (110). The outer member can include an expandable distal portion (110b), an expandable proximal portion (110a), and a central portion (110c) of limited expandability. The interluminal medical treatment device can include at least one membrane (120). The outer member and at least one membrane may define a housing area (130) positioned between the proximal portion and distal portion of the outer member. The outer member and at least one membrane can be configured to redirect fluid flow within a body lumen away from the housing area inner member or inner passageway.
