Abstract

An anchor-insertion tool for securing an anchor having a suture extending therefrom to a structure within a patient'"'"'s body is provided. The anchor-insertion tool comprises an elongate shaft having distal and proximal ends, an anchor-receiving tip at the distal end, at least one groove extending from the tip at least partially along the length of the shaft, and at least one depression extending about the circumference of the shaft and intersecting the groove. A loaded anchor-insertion tool is provided, along with a surgical method for employing the anchor-insertion tool. A surgical template and suture retriever are also provided.

Claims

1. A method for retrieving a portion of a suture from within a patient'"'"'s body, comprising:

(a) providing a suture retriever having a retrieving end;

(b) inserting said retrieving end into the patient'"'"'s body through the patient'"'"'s vagina; and

(c) pulling a portion of said suture into the patient'"'"'s vagina with the retrieving end of said suture retriever.

2. The method of claim 1, wherein said retrieving end is vaginally inserted into the patient'"'"'s body through the periurethral tissue, and wherein said portion of said suture is pulled into the vagina through the periurethral tissue.

3. The method of claim 1, wherein said retrieving end has a sharp tip, such that said step of vaginally inserting said retrieving end into the patient'"'"'s body comprises urging said sharp tip through the vaginal mucosa and periurethral fascia.

4. The method of claim 1, wherein said suture is positioned within the space of Retzius and extends from a bone anchor secured to the pubic bone of the patient.

5. The method of claim 3, wherein:

said suture retriever further comprises a handle; and

said retrieving end comprises a shaft, with said sharp tip located at one end thereof;

and wherein said handle and said shaft are configured such that when said retrieving end is vaginally inserted into the patient'"'"'s body to retrieve said suture, at least a portion of said handle remains substantially outside of the patient'"'"'s vagina.

6. The method of claim 3, wherein:

said suture retriever further comprises a handle and a midshaft positioned between said retrieving end and said handle;

said retrieving end comprises a shaft, with said sharp tip located at one end thereof;

said midshaft and said shaft of said retrieving end are secured to one another in an angular relationship; and

said handle and said midshaft are secured to one another in an angular relationship;

such that when said retrieving end is vaginally inserted into the patient'"'"'s body to retrieve said suture, at least a portion of said handle remains substantially outside of the patient'"'"'s vagina.

7. A method of passing the tail of a suture from the interior of the patient'"'"'s body into the patient'"'"'s vagina, comprising:

(a) providing a suture retriever having a retrieving end;

(b) inserting said retrieving end of the suture retriever into the vagina and thereafter through the vaginal mucosa and periurethral fascia into the patient'"'"'s body;

(c) snaring said suture tail with said retrieving end; and

(d) withdrawing said retrieving end into the vagina along with the suture tail.

8. The method of claim 7, wherein a portion of said suture retriever remains outside of the patient'"'"'s vagina.
