SUTURE LOCK
First Claim
1. A suture lock for fixing strands of one or more sutures relative to tissue, the suture lock comprising:
- a locking cylinder having a tubular body defining an interior surface and an exterior surface, the interior surface defining a first interior passageway, the tubular body defining a first aperture and a second aperture, the first aperture spaced apart from the second aperture, the first aperture and the second aperture in communication with the first interior passageway and adapted for threading suture strands therebetween; and
a retaining sleeve defining a second interior passageway sized to receive the tubular body of the locking cylinder, the second interior passageway sized to compress the suture strands between the tubular body and the retaining sleeve.

Abstract
A suture lock, as well as related methods, are provided for fixing strands of one or more sutures relative to tissue. The suture lock and method are simple and reliable in use, facilitate complete perforation closure and adjustment of the suture strands, and are adaptable to a variety of suture fixation and perforation closure situations. The suture lock includes a locking cylinder and a retaining sleeve. The locking cylinder has a tubular body defining an interior surface and an exterior surface. The interior surface defines a first interior passageway. The tubular body defines a first aperture and a second aperture that are spaced apart and in communication with the first interior passageway. The retaining sleeve defines a second interior passageway sized to receive the tubular body of the locking cylinder. The suture strands are compressed between the tubular body and the retaining sleeve.

10. A suture lock for fixing strands of one or more sutures relative to tissue, the suture lock comprising:
-
a locking cylinder having a tubular body defining a first interior passageway, the tubular body defining a first aperture and a second aperture, the first aperture and the second aperture in communication with the first interior passageway; a retaining sleeve defining a second interior passageway sized to receive the tubular body of the locking cylinder; and the suture lock being operable between an unlocked configuration and a locked configuration, the locking cylinder and retaining sleeve being connected in the locked configuration and being separated in the unlocked configuration, the locking cylinder and retaining sleeve compressing elongate sections of the suture strands between the first and second apertures in the locked configuration. - View Dependent Claims (11, 12, 13)

14. A method for fixing strands of one or more sutures relative to tissue, the method comprising:
-
providing a suture lock comprising a locking cylinder and a retaining sleeve, the locking cylinder having a tubular body defining a first interior passageway, the tubular body defining spaced apart first and second apertures in communication with the first interior passageway, the retaining sleeve defining a second interior passageway sized to receive the locking cylinder and compress the suture strands between the tubular body and the retaining sleeve; threading the suture strands through the locking cylinder, the suture strands extending through the first internal passageway, through the first aperture, along the exterior of the tubular body, through the second aperture, and again through the first internal passageway; translating the locking cylinder distally along the suture strands; threading the suture strands through the second internal passageway of the retaining sleeve; translating the retaining sleeve distally along the suture strands; placing the suture strands in tension; and translating the retaining sleeve over the locking cylinder to compress the suture strands between the retaining sleeve and locking cylinder. - View Dependent Claims (15, 16, 17, 18, 19, 20)
