Systems and methods for positioning and compacting a bodily implant

#The present embodiments relate to medical treatment devices and procedures, in particular to positioning and compacting a bodily implant.

#Various treatments are commonly used for treating diseases of hollow anatomical structures (HAS), such as venous reflux disease and other diseases. One example endovenous treatment involves placement of an occluding implant in the HAS, such as in the great saphenous vein (GSV). The implant may be, for example, a bioresorbable fibrous body, which may be textured to impart bulk. The implant causes a partial occlusion of the HAS, followed by a complete or substantially complete occlusion, such as by formation of an organic fibrotic occlusion resulting from the body's natural foreign body healing response.

#After placing the implant at the treatment site, the implant may be expanded to partially or fully occlude the HAS in the radial direction. For example, the implant may be self-expanding. Alternatively, or in addition, a system for placing the implant may include a mechanism for manually expanding the implant. However, in some instances, the implant in its radially expanded condition does not occlude the HAS sufficiently to cause a complete or substantially complete occlusion to treat the disease. Such a lack of total occlusion maybe cause by not enough radial expansion and/or not enough density of material.

#The present embodiments now will be discussed in detail with an emphasis on highlighting the advantageous features. These embodiments are for illustrative purposes only. These drawings include the following figures, in which like numerals indicate like parts:

#FIG. 1A is a side elevation view of a fibrous bodily implant;

#FIGS. 1B-1D are schematic views of a method for delivering a bodily implant into a hollow anatomical structure (HAS);

#The following detailed description describes the present embodiments with reference to the drawings. In the drawings, reference numbers label elements of the present embodiments. These reference numbers are reproduced below in connection with the discussion of the corresponding drawing features.

#Directional terms used herein, such as proximal, distal, upper, lower, clockwise, counterclockwise, etc., are used with reference to the configurations shown in the figures. For example, a component that is described as rotating clockwise when viewed from the perspectives shown in the figures may be said to rotate counterclockwise when viewed from the opposite perspective. Furthermore, the present embodiments may be modified by altering or reversing the positions or directions of movement of various components. Accordingly, directional terms used herein should not be interpreted as limiting.

#FIG. 1A illustrates one example of an implant 10 for occlusion of a hollow anatomical structure (HAS). The implant 10 comprises a bioresorbable body 12. In one embodiment, the body 12 comprises a bioresorbable material in fibrous form, which can comprise a collection of individual fibers that can be spun into multi-filament yarns. The fibers or yarns can be textured to impart bulk. In one embodiment, multiple fibers or yarns can be assembled together to form the body 12. The textured fibers or yarns can be made wavy to prevent adjacent yarns from lying closely together and impart bulk and a self-expanding property to the body 12. The fibers can be treated and/or agglomerated in any suitable manner to achieve a desired texture, density, geometry, etc. The fibers can be made or treated such that the body 12 can be compressible and/or expandable. For example, as shown in the illustrated embodiment, the body 12 can naturally assume a radially expanded condition and convert to a compressed condition upon application of a compressive force. Alternatively, the body 12 can naturally assume a compressed condition and convert to an expanded condition upon application of an expansive force. The bioresorbable material can be any suitable bioresorbable material, such as a material from the family of alpha hydroxy acids, for example polylactide (PLA) and/or polyglycolide (PGA).
