Abstract:
1. A suture securement apparatus for selectively and releasably securing a suture ring of a catheter in connection with sutures positioned adjacent the suture ring of the catheter, the suture securement apparatus comprising: a body having a cavity positioned therein; a plunger slidably disposed within the cavity of the body and biased to secure the sutures and enable releasable engagement of the sutures; an extension tube extending a predetermined distance from the body such that a tip of the extension tube is adaptable to engage the sutures adjacent to an insertion point of the sutures without interference from the body; and a threading assembly having a base and a suture engaging portion to facilitate threading of the sutures through the suture ring and through a lumen of the suture securement apparatus, wherein the plunger comprises a plunger lumen through the plunger, wherein the plunger lumen forms a portion of the lumen of the suture securement apparatus, wherein the plunger lumen is configured to have a cross-section in the shape of a tear drop, and wherein at least a portion of a lumen of the extension tube is configured to have a cross-section in the shape of a tear drop and oriented such that a pointed portion of the tear drop is oriented 180 degrees relative to the pointed portion of the tear drop shape of the plunger lumen cross-section and wherein the plunger is slidably disposed within the body such that the cross-section of the plunger lumen is configured to move substantially along a plane parallel to the cross-section of the extension tube lumen to secure and release the sutures such that when the sutures are secured by the suture securement device the sutures are engaged between pointed portions of the tear drop shapes of the plunger lumen and extension tube and wherein when the plunger is in a fully depressed position, rounded portions of the tear drop shaped cross sections of the plunger lumen and the extension tube lumen are aligned such that the sutures are displaceable with respect to the suture securement apparatus when the sutures are also extending through the opening and the extension tube lumen.
