Abstract

A proximal housing for a full-thickness resection device (FTRD) is provided with a plurality of chambers through which fasteners are introduced into a portion of tissue to be resected. The proximal housing has a noncircular cut-out opposite the plurality of chambers to receive a noncircular endoscope. The proximal housing also is provided with a resection cavity into which the tissue to be resected is to be received. In addition, shaft openings are provided through which mounting shafts may be inserted. A noncircular endoscope is also disclosed for insertion into the cut-out whereby the endoscope has passages to house the functions of remote viewing, illumination, insufflation and irrigation.

Claims

1. A proximal housing for a full-thickness resection device comprising:

a plurality of chambers through which fasteners are introduced into a portion of tissue to be resected;

a noncircular cut-out formed in the proximal housing opposite the plurality of chambers to receive an endoscope;

a resection cavity into which the portion of tissue is to be received;

at least one shaft opening through which a mounting shaft may be inserted; and

a noncircular endoscope of substantially the same shape as the noncircular cut-out inserted into said noncircular cut-out.

2. The proximal housing of claim 1, wherein the plurality of chambers are configured so as to produce an essentially elliptical fastener pattern.

3. The proximal housing of claim 1, wherein the noncircular endoscope contains an optical source, at least one light source, an insufflation passage and an irrigation passage.

4. The proximal housing of claim 1, wherein the fasteners are staples.

5. The proximal housing of claim 1, wherein at least one shaft opening includes two shaft openings.

6. The proximal housing of claim 1, wherein the noncircular endoscope is elliptical in shape.

7. A proximal housing for a full-thickness resection device comprising:

a plurality of chambers through which fasteners are introduced into a portion of tissue to be resected;

a noncircular cut-out formed in the proximal housing opposite the plurality of chambers to receive an endoscope of noncircular shape;

a resection cavity into which the portion of tissue is to be received; and

at least one shaft opening through which a mounting shaft may be inserted.

8. The proximal housing of claim 7, wherein the plurality of chambers are configured so as to produce an essentially elliptical fastener pattern.

9. The proximal housing of claim 7, wherein the fasteners are staples.

10. The proximal housing of claim 7, wherein at least one shaft opening includes two shaft openings.

11. The proximal housing of claim 7, wherein the noncircular cut-out is elliptical.
