摘要： The present disclosure relates to a loop vascular device and a method to retrieve said device from the body vessel of a patient. The loop vascular device comprises a loop having a first portion extending distally to a splitting portion, and a second portion also extending distally to the splitting portion, defining a close state of the loop. The splitting portion may be split such that the first portion is separated from the second portion when in the body vessel, defining an open state of the loop. In the open state, the loop may be easily retrieved through ingrowth in the body vessel, reducing or eliminating possible negative effects to the vessel wall.

摘要： The disclosure provides for a spiral filter and delivery apparatus where the filter comprises a support supporting a body and defining a frame. The frame comprises a proximal end extending to a distal end. A filtering member may be attached to the proximal end and extend distally to the distal end. The filtering member and the frame may move between a delivery state and a deployed state. In the deployed state, the frame extends helically within the circumference of the body vessel and has a filtering lumen formed therethrough. The filtering member may be disposed within the filtering lumen in a spiral for filtering within the intended body vessel.

摘要： The present disclosure relates to a loop vascular device and a method to retrieve said device from the body vessel of a patient. The loop vascular device comprises a loop having a first portion extending distally to a first bar, and a second portion extending distally to a second bar. In a close state of the loop, the first and second bars are maintained or housed inside a first cannula. The first cannula may be in contact with a second cannula. Upon desiring to open the loop, the physician may separate the first cannula from the second cannula, allowing the bars to exit the first cannula and disconnect from each other, defining the open state of the loop. In the open state, the loop may be easily retrieved through any ingrowth in the body vessel.
摘要翻译：本公开涉及一种环路血管装置和从患者的身体血管中检索所述装置的方法。环形血管装置包括具有向远端延伸到第一杆的第一部分和向远侧延伸到第二杆的第二部分的环。在环的闭合状态下，第一和第二杆被保持或容纳在第一套管内。第一套管可以与第二套管接触。当希望打开回路时，医生可以将第一插管与第二套管分开，从而允许杆离开第一套管并且彼此断开，从而限定回路的打开状态。在打开状态下，可以通过身体血管中的任何向内生长容易地回收回路。

摘要： The disclosure provides a filter apparatus and method of filtering in a body vessel. The filter apparatus comprises a filter unit and an expandable introducer designed to deliver the filter unit to the target filtering site. The filter unit attaches to the expandable introducer via a plurality of anchors on the filter unit. The expandable introducer delivers and presses the anchors to the vessel wall during implantation. After implantation, the filter unit exerts minimal or about zero radial force against the vessel wall.

摘要： A vena cava filter includes a plurality of filter legs with distal ends. Each distal end is a tip which curves radially outwardly and ends in a spherical or part spherical enlarged head element. A biodegradable barb is attached to the enlarged head element and is made of a biodegrade material, such that after degradation the enlarged head element also is left embedded in the vessel wall. The degradation of the barb will prevent further penetration of the distal end of the filter legs into the vessel wall and avoid any risk of piercing through the vessel wall. The enlarged head element also ensures that the distal ends of the filter legs remain firmly attached into the vessel wall in order to ensure correct long term placement of the filter in the vessel.
摘要翻译：腔静脉过滤器包括多个具有远端的过滤腿。每个远端是径向向外弯曲并以球形或部分球形扩大头元件端部的尖端。可生物降解的倒钩连接到扩大的头部元件并且由生物降解材料制成，使得在降解之后，扩大的头元件也被嵌入容器壁中。倒钩的降解将防止过滤器腿的远端进一步穿透到容器壁中，并避免穿过血管壁的任何危险。扩大的头部元件还确保过滤器腿的远端保持牢固地附接到容器壁中，以确保过滤器在容器中的正确长期放置。
