Abstract
A suturing system for receiving and retaining a suture is disclosed and includes a suture, at least one retainer, and at least one needle. Each needle is able to receive and removably retain the suture within a groove located in a tapered end. The retainer has a body that defines an aperture therethrough. The shape of the aperture is formed by a central passageway, and a pair of diametrically opposed slots extending radially outward from the central passageway. The central passageway is sized to allow passage of the needle therethrough. Each slot defines a tortured path section that permits passage of the suture in a first direction and inhibits passage of the suture in a second direction.

A suturing system for receiving and retaining a suture, comprising:
- a suture;
- at least one needle having a tapered end and a groove across the tapered end that receives and removably retains a portion of the suture;
- and
- at least one retainer having a body defining an aperture, the shape of the aperture being defined by a top surface and a bottom surface, a central passageway extending between the top surface and the bottom surface and having a pair of diametrically opposed slots extending radially outward from the central passageway, the central passageway being sized to allow passage of the needle therethrough, each slot defines a tortured path section between the top surface and the bottom surface, the suture conformable within the tortured path section such that passage of the suture is permitted in a first direction and inhibited in a second direction.
A suture retainer cartridge for use with a surgical stapling-type of device, comprising:
- a cartridge body;
- a needle;
- and
- at least one suture retainer configured to be removably secured within the cartridge body, the at least one suture retainer having a body defining an aperture, the shape of the aperture being defined by a top surface and a bottom surface, a central passageway extending between the top surface and the bottom surface and having a pair of diametrically opposed slots extending radially outward from the central passageway, the central passageway being sized to allow passage of the needle therethrough, each slot defines a tortured path section between the top surface and the bottom surface, a suture conformable within the tortured path section such that passage of the suture is permitted in a first direction and inhibited in a second direction.
