Abstract
An insertion device includes an elongate member and a stylet. The elongate member has a proximal end portion, a distal end portion, and defines a lumen therethrough. The stylet has a proximal end portion, a distal end portion, and is slidably coupled to the elongate member. The stylet is configured to move from a first position to a second position with respect to the elongate member. The proximal end portion of the stylet is configured to removably couple a mesh carrier thereto. A portion of the proximal end portion of the stylet is disposed outside of the lumen of the elongate member when the stylet is in its first position and is disposed within the lumen when the stylet is in its second position.
Claims20
An insertion device, comprising:
- a handle member defining a cavity and a longitudinal axis;
- an elongate member having a proximal end portion, a distal end portion, and defining a lumen therethrough, the lumen having a diameter of a first size, the elongate member including a curved portion between the proximal end portion and the distal end portion, the distal end portion configured to removably and frictionally couple a tissue anchor thereto such that a portion of the tissue anchor is disposed within the lumen defined by the elongate member and a portion of the tissue anchor having a diameter of a second size greater than the first size is disposed outside of the lumen defined by the elongate member, at least a portion of the elongate member being disposed within the cavity of the handle member, the elongate member being movably coupled to the handle member;
- and
- a stylet having a proximal end portion, a distal end portion and being configured to move from a first position to a second position with respect to the elongate member, and when the stylet is in the first position, the distal end portion of the stylet defines a longitudinal axis that is offset from a longitudinal axis defined by the distal end portion of the elongate member, the stylet being configured to engage the tissue anchor to remove the tissue anchor from the elongate member such that a longitudinal axis defined by the tissue anchor is substantially orthogonal to the longitudinal axis defined by the handle, member the stylet being fixedly coupled to the handle member.
An insertion device, comprising:
- a handle member defining a cavity;
- an elongate member having a proximal end portion, a distal end portion, and defining a lumen therethrough, wherein a longitudinal axis defined by the proximal end portion of the elongate member is substantially orthogonal to a longitudinal axis defined by the distal end portion of the elongate member, at least a portion of the elongate member being disposed within the cavity, the elongate member being movably coupled to the handle member;
- and
- a stylet having a proximal end portion and a distal end portion, at least a portion of the stylet disposed within the lumen of the elongate member, the stylet being slidably coupled to the elongate member such that the stylet is configured to move from a first position to a second position with respect to the elongate member, when the stylet is in the first position, the distal end portion of the stylet defines a longitudinal axis that is offset from the longitudinal axis defined by the distal end portion of the elongate member, the stylet being fixedly coupled to the handle member.
A method of inserting a tissue anchor into a body of a patient, comprising:
- coupling the tissue anchor to a distal end portion of an elongate member of an insertion device such that a portion of the tissue anchor is disposed within a lumen defined by the elongate member and a portion of the tissue anchor is disposed outside of the lumen defined by the elongate member, a diameter of the portion of the tissue anchor disposed outside of the lumen being larger than a diameter of the lumen, the insertion device having an elongate member, a handle member, and a stylet, at least a portion of the elongate member being disposed within a cavity defined by the handle member, the elongate member being movably coupled to the handle member, the stylet being fixedly coupled to the handle member, the coupling of the tissue anchor includes extending a stylet through a filament coupled to the tissue anchor;
- inserting the insertion device into the body;
- decoupling the tissue anchor such that a longitudinal axis defined by the tissue anchor is substantially orthogonal to an axis defined by the proximal end portion of the elongate member;
- and
- removing the insertion device from the body.
