Abstract
Abstract A device and method for collecting from a tissue surface, a sample of tissue, including tissue specimens, polyps, or the like. A device body defines a forward-facing tissue receiving opening of substantially predetermined width through which tissue may pass when the opening is near the tissue surface. A severing element is actuatable across the width of the tissue receiving opening when tissue from the surface extends through the opening for severing the tissue from the surface. A storage space proximal of and adjacent the opening is provided for storage of multiple, successively taken samples by repeatedly passing tissue through the opening and actuating the severing element.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
126 words
A device for collecting a sample of tissue from a tissue surface, comprising: a device body having a central axis and defining a forward facing tissue receiving opening coaxial with said central axis through which tissue may pass when said opening is near said tissue surface, a severing element forming a severing element tissue opening coaxial with said central axis, said severing element being actuable across said tissue receiving opening when tissue from said surface extends through said tissue receiving opening and said severing element tissue opening for severing said tissue from said surface, and a storage space proximal of and adjacent said tissue receiving opening for storage of multiple tissue samples by repeatedly passing tissue through said tissue receiving opening and actuating said severing element.
Claim 2
Independent Claim
126 words
A device for collecting a sample of tissue from a tissue surface, comprising: a device body having a central axis and defining a forward facing tissue receiving opening coaxial with said central axis through which tissue may pass when said opening is near said tissue surface, a severing element forming a severing element tissue opening coaxial with said central axis, said severing element being actuable across said tissue receiving opening when tissue from said surface extends through said tissue receiving opening and said severing element tissue opening for severing said tissue from said surface, and a storage space proximal of and adjacent said tissue receiving opening for storage of multiple tissue samples by repeatedly passing tissue through said tissue receiving opening and actuating said severing element.
Claim 3
Dependent Claim
22 words
The device of claim 1 wherein said device further comprises an axially movable retractor for engaging a tissue and drawing it proximally.
Claim 4
Dependent Claim
31 words
The device of claim 2 wherein said retractor is extendable distally beyond said tissue receiving opening for engaging said tissue surface and retractable proximally to draw tissue through said tissue-receiving opening.
Claim 5
Dependent Claim
25 words
The device of claim 3 wherein said retractor is a spear-form element adapted to pierce tissue and has a retaining barb on its distal end.
Claim 6
Dependent Claim
49 words
The device of claim 1 wherein said severing element comprises a cutting loop, said cutting loop being actuatable between an open configuration that is oriented generally coaxially with said tissue-receiving opening and a closed configuration in which the loop passes across said tissue receiving opening to sever said tissue.
Claim 7
Dependent Claim
23 words
The device of claim 5 wherein said cutting loop is actuated by a control wire extending parallel with the axis of said body.
Claim 8
Dependent Claim
21 words
The device of claim 6 wherein said control wire passes through a lumen extending to an opening adjacent said tissue-receiving opening.
Claim 9
Dependent Claim
17 words
The device of claim 7 wherein said cutting loop is actuated by withdrawing it into said lumen.
Claim 10
Dependent Claim
37 words
The device of claim 5 including a retractor extendable distally beyond said tissue receiving opening and said cutting loop for engaging said tissue surface and retractable proximally to draw tissue through said tissue-receiving opening and cutting loop.
Claim 11
Dependent Claim
25 words
The device of claim 9 wherein said retractor is a spear-form element adapted to pierce tissue and having a retaining barb on its distal end.
Claim 12
Independent Claim
131 words
A method for collecting a sample of tissue from a tissue surface, comprising: providing a sampling device including: a device body having a central axis and defining a forward-facing tissue receiving opening coaxial with said central axis through which tissue may pass when said opening is near said tissue surface, and a severing element forming a severing element tissue opening coaxial with said central axis, said severing element being actuable across said tissue receiving opening when tissue from said surface extends through said tissue receiving opening and said severing element tissue opening for severing said tissue from said surface, positioning said device near said tissue surface, receiving tissue through said tissue-receiving opening and said severing element tissue opening, and actuating said severing element to sever a tissue sample from said surface.
Claim 13
Independent Claim
131 words
A method for collecting a sample of tissue from a tissue surface, comprising: providing a sampling device including: a device body having a central axis and defining a forward-facing tissue receiving opening coaxial with said central axis through which tissue may pass when said opening is near said tissue surface, and a severing element forming a severing element tissue opening coaxial with said central axis, said severing element being actuable across said tissue receiving opening when tissue from said surface extends through said tissue receiving opening and said severing element tissue opening for severing said tissue from said surface, positioning said device near said tissue surface, receiving tissue through said tissue-receiving opening and said severing element tissue opening, and actuating said severing element to sever a tissue sample from said surface.
Claim 14
Dependent Claim
38 words
The method of claim 11, comprising: providing said sampling device at the end of an elongate flexible member, and delivering said device by threading said device through the body to a desired tissue surface deep within the body.
Claim 15
Dependent Claim
63 words
The method of claim 11, comprising: providing a sampling device that further includes a storage space proximal of and adjacent said tissue receiving opening for storage of multiple samples by repeatedly passing tissue through said tissue receiving opening and actuating said severing element, and repeating said steps of positioning and actuating to take multiple tissue samples without removing said device from the body.
