Method for delivering a plurality of fasteners
View Patent ↗A delivery device for delivering a plurality of individual surgical fasteners. The delivery device includes a drive mechanism having distal and proximal ends. The drive mechanism has a moving member and a fixed opposing member, wherein the moving member is moveable proximally and distally with respect to the delivery device. The moving member has a sharpened distal end for piercing tissue. The device includes at least one surgical fastener located between the first and the second members. Each of the at least one surgical fasteners has a proximal end and a distal end. The device also has an actuator having at least two sequential positions. A first position for moving the moving member distally and piercing tissue, and a second position for moving the moving member proximally, thereby deploying the distal end of the fastener.
1. A method for delivering a plurality of fasteners, comprising:
handling a device having a plurality of fasteners disposed in a tube having a longitudinal axis, the plurality of fasteners substantially aligned with the longitudinal axis and including a distal-most fastener and a proximal fastener, the proximal fastener positioned proximal to the distal-most fastener within the tube;
engaging a proximal end of the distal-most fastener and proximal fastener with an engaging member when the engaging member is at a first position, and engaging the proximal end of the distal-most fastener and proximal fastener at more than one surface of the distal-most fastener;
then, moving the engaging member to a second position, wherein the second position is distal to the first position;
penetrating tissue with a member having a sharp end, the member disposed at least partially within the tube, wherein the penetrating and the moving are performed simultaneously;
releasing the distal-most fastener from the tube; and
retracting the engaging member relative to the distal-most fastener by moving the engaging member from the second position to the first position such that the engaging member engages the proximal end of the proximal fastener.
2. The method of claim 1 , wherein the moving step comprises the step of moving the engaging member to the second position along a longitudinal axis.
3. The method of claim 1 , wherein the moving step comprises the step of the moving the distal-most fastener from the first position to the second position along a longitudinal axis.
4. A method for delivering a plurality of fasteners, comprising:
handling a device having a plurality of fasteners disposed in a tube having a longitudinal axis, the plurality of fasteners substantially aligned with the longitudinal axis and including a distal-most fastener and a proximal fastener, the proximal fastener positioned proximal to the distal-most fastener within the tube;
engaging a proximal end of the distal-most fastener and proximal fastener with an engaging member when the engaging member is at a first position, and engaging the proximal end of the distal-most fastener and proximal fastener at more than one surface of the distal-most fastener;
then, moving the engaging member to a second position, wherein the second position is distal to the first position;
penetrating tissue with a member having a sharp end, the member disposed at least partially within the tube, wherein the penetrating and the moving are performed simultaneously;
releasing the distal-most fastener from the tube; and
retracting the engaging member relative to the tube by moving the engaging member from the second position to the first position such that the engaging member engages the proximal end of the proximal fastener.
5. The method of claim 4 , wherein the moving step comprises the step of moving the engaging member to the second position along a longitudinal axis.
6. The method of claim 4 , wherein the moving step comprises the step of the moving the distal-most fastener from the first position to the second position along a longitudinal axis.
