Embodiment Construction

[0019] The following detailed description is only exemplary, and is not intended to limit the present disclosure and its application or use.

[0020] Referring now to the accompanying drawings, a small debris retrieval device or collection line embodying the principles of the present invention is shown as Figure 1A shown and numbered 10. Collection wire 10 includes a shaft 12 having a proximal end 20 and a distal end 22 . A plurality of tips 16 are attached to the distal end 22 of the shaft 12 . exist Figure 1A In the configuration shown, the plurality of tips 16 are a plurality of filaments interwoven into the fibrous structure 14 . The fibrous structure 14 is porous to allow fluid flow while trapping small stone fragments and dust particles generated during lithotripsy.

[0021] In use, the physician inserts the collection wire 10 into the patient's anatomy such that the fibrous structure 14 is located near an area of ​​the patient's anatomy that contains small stone f...

Abstract

The present invention discloses a medical device for retrieving small fragments from within a patient's anatomy, comprising a collection wire configured for entry into the patient's anatomy. The collection wire includes a distal end having a plurality of tips configured to attract stone fragments from the patient's anatomy.

Description

[0001] related application [0002] This application claims priority to US Patent Application 14 / 662,992, filed March 19, 2015, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to a medical device. More specifically, the present disclosure relates to a device for retrieving small debris. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art. [0005] Lithotripsy is a common procedure used to break up stones in the urinary tract, kidneys and / or bladder. However, lithotripsy may leave stone fragments that, for example in the lower pole of the kidney, serve as nucleation sites for future stone formation. Due to the difficulty in capturing very small dust fragments using conventional removal devices such as, for example, calculus mesh baskets, these fragments remain in the patient's body after...
