Problems solved by technology

However, complications can occur during the removal procedure, especially when the body has absorbed parts of the IVC filter and thus makes removal of the IVC filter very difficult
In some cases where the IVC filter is substantially absorbed by the body (e.g., the tissue enclosing the portion of the IVC filter), forced removal of the IVC filter may be very dangerous for the patient, as attempts to remove the IVC filter While too much pulling pressure applied can tear and / or rupture the IVC

[0023] review

[0024] To better understand the various functions and features of systems and methods for delivering and / or removing foreign objects, a delivery and / or removal device (referred to herein as a "delivery-removal device") is provided review. This review and many of the embodiments herein are described in the context of using a delivery-removal device to retrieve a medical device (ie, an inferior vena cava (IVC) filter). However, the delivery-removal device can be used with respect to other foreign objects, such as other medical devices, eg, other vascular filters, vascular occlusive devices, prosthetic devices (eg, valves), etc. The delivery-removal device can also be used to retrieve other foreign objects, such as clots or thrombi, from within the subject's vasculature. The delivery-removal device can likewise be used to deliver prosthetic medical devices to the body in the vasculature or otherwise.

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 forciblyremoved. 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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of and priority over U.S. Provisional Application Serial No. 62 / 692260, filed June 29, 2018, which is hereby incorporated by reference in its entirety for all purposes. technical field [0003] Various aspects of the present disclosure relate to a system and method for implants and deployment devices. Background technique [0004] Temporary inferior vena cava (IVC) filters are placed much like permanent IVC filters, but are designed so that they can be retrieved during subsequent intravascular procedures. As the name implies, the IVC filter is placed inside the IVC (the large vein in the abdomen that returns blood from the lower body to the heart). Patients requiring IVC filters are typically at high risk of having pulmonary embolism. IVC filters are designed to catch emboli (blood clots) and prevent them from reaching the lungs. Temporary IVC filters are typically removed from th...
