Problems solved by technology

Grasping a retrieval feature using a snare typically requires the user to manipulate the snare over the retrieval feature, which may vary depending on various factors (e.g., geometry and location of the retrieval feature within the lumen, structure and nature of the snare, use of real-time visualization techniques). (e.g., fluoroscopy) to visualize the ability to retrieve features and / or snares) but difficult

Embodiment Construction

[0126] Such as Figure 1A and 1B As shown in , an embodiment of a retrieval device 10 (eg, a snare) includes a first or spindle shaft 12 having a distal end 14 and a proximal end 16 . At the distal end 14 of the shaft 12 is a plurality of loop elements 18 . In some embodiments, while device 10 may generally have at least two loop elements 18 , it may have three or more loop elements 18 . These loop elements 18 are attached proximally to the distal end 14 of the shaft 12 via a hypotube component 20 and may be free and independent at their most distal end. In other embodiments, the distal end of loop element 18 may be secured or connected to an adjacent loop element using, for example, a loop connector, as described in more detail below. Loop element 18 may be a polymeric or metallic material, and is typically radiopaque and flexible.

[0127] Loop elements 18 may have overlapping regions 31 spanning L1 between adjacent loop elements. In some embodiments, L1 may be less than...

Abstract

The present invention relates generally to devices and methods for retrieving or manipulating objects within a lumen. More specifically, embodiments of the invention relate to devices and methods for retrieving or manipulating medical devices from a body lumen. One embodiment of the present invention provides a novel and improved retrieval snare and method of fabricating and using the same. The snare includes a snare wire, having a distal end and a proximal end, for use in the human anatomy, such as but not limited to blood vessels, pulmonary airways, reproductive anatomy, gastrointestinal anatomy, and organs such as the kidneys or lungs. The device enables a user to capture a foreign object located within the human anatomy, grasp said object in a controlled manner, and retrieve and remove said object from the human anatomy.
