Embodiment Construction

[0036] For the terms defined below, these definitions shall apply unless a different definition is given in the claims or elsewhere in this specification.

[0037] It is assumed herein that all numerical values ​​are modified by the term "about", whether expressly stated or not. The term "about" generally refers to a range of numbers that one of ordinary skill in the art would consider equivalent (ie, having the same function or result) to the recited value. In many instances, the term "about" may include figures that are rounded to the nearest significant figure.

[0038] The recitations of numerical ranges by endpoints include all numbers subsumed within that range (eg, 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, and 5).

[0039] As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the content clearly dictates otherwise. As used in this specification and the appended claims, the term "or" is general...

Abstract

A tissue removal device includes a housing, an outer tube having a distal portion configured for transcervical insertion into a uterus, an inner tube slidably disposed within the outer tube lumen, a vacuum generation chamber disposed within the housing, a movable piston slidably disposed in the vacuum generation chamber, a collection chamber, a manual actuator moveably coupled to the housing and operatively coupled to the piston, and proximal and distal one-way valves. The outer tube has an outer tube lumen, a tissue in-take opening proximate a distal end thereof, and a proximal end coupled tothe housing. The inner tube has an inner tube lumen extending from an open inner tube distal end to an open inner tube proximal end, the open inner tube distal end comprising a cutting edge configured to sever intrauterine tissue extending through the tissue in-take opening in the outer tube.

Description

[0001] Related patent application data [0002] This application claims the benefit of U.S. Provisional Patent Application Serial No. 62 / 255,650, filed November 16, 2015, under 35 U.S.C. §119. The entire contents of the aforementioned applications are incorporated by reference into this application in their entirety as if fully set forth herein. technical field [0003] The present disclosure relates generally to a method, system, and device for surgery, and more particularly, to a tissue removal system for removing body tissue, including uterine polyps and other abnormal gynecological tissue. Background technique [0004] In many instances, it is desirable to remove unwanted tissue from a patient. Uterine polyps and fibroids represent two such unwanted tissues. Uterine polyps are fibrous masses that commonly develop from the lining of the uterus. Uterine fibroids are well-defined, noncancerous tumors that commonly arise in the smooth muscle layer of the uterus. In many ...
