Systems and methods for implants and deployment devices

Abstract

After a prolonged period in the body, an IVC filter can be substantially absorbed by the body. When this occurs, it can be very difficult and/or dangerous for the patient if the IVC filter is forcibly removed. Thus, it is desirable to have systems and methods for safely abandoning the removal procedure of the IVC filter. Example embodiments of an apparatus for safely abandoning the removal procedure of the IVC filter can include: a sleeve having a lumen and a first hole on a wall of the sleeve; a shaft slidably disposed within the lumen of the sleeve; a flexible distal extension comprising a braid structure with a first opening; and a first lasso encircling a portion of the first opening of the braid.

1 . A method for manufacturing a medical device, the method comprising:
 encircling a lasso at a proximal opening of a funnel shaped extension, wherein the lasso has a first and second end;   securing the first end of the lasso to an inner sleeve of the medical device, wherein the inner sleeve comprises a lumen and a first hole on its sidewall;   threading the second end of the lasso through the first hole on the inner sleeve;   inserting an inner shaft within the lumen of the sleeve; and   wrapping the second end of the lasso around the inner shaft to secure the second end of the lasso.   
     
     
         2 . The method of claim  13 , wherein the second end of the lasso is partially wrapped around the inner shaft. 
     
     
         3 . The method of claim  13 , wherein the second end of the lasso is fully wrapped around the inner shaft. 
     
     
         4 . The method of claim  13  further comprising threading the second end of the lasso back through the first hole after being wrapped around the inner shaft. 
     
     
         5 . The method of claim  13  further comprising threading the second end of the lasso through a second hole of the inner sleeve after being wrapped around the inner shaft. 
     
     
         6 . The method of claim  13  further comprising a second lasso encircling the proximal opening of the braid, wherein a first end of the second lasso is coupled to the sleeve, and a second end of the second lasso is threaded through the first opening of the sleeve. 
     
     
         7 . The method of claim  13 , wherein threading the second end of the lasso through the first hole comprises threading the second end of the lasso from outside of the inner sleeve. 
     
     
         8 . The method of claim  13 , wherein threading the second end of the lasso through the first hole comprises threading the second end of the lasso from inside of the inner sleeve. 
     
     
         9 . The method of claim  13  further comprising attaching the inner shaft to a cam configured to move the inner shaft in an axial direction.
