Abstract
The present disclosure provides systems, methods, devices, and kits for delivering an implant to an anatomical site in a patient. In some instances, a delivery device for delivering an implant includes a receiver with a through-lumen and a transfer pin for associating with the implant and the lumen. In some embodiments, a method for delivering an implant to an anatomical site in a patient comprises transferring the implant or a portion thereof from one section of a delivery device to another.
Claims43
A device for delivering an implant to an anatomical site in a patient comprising:
- a first section including a receiver located at a distal portion of the first section, the receiver including a through-lumen;
- and
- a second section including a transfer pin located at a distal portion of the second section, the transfer pin being adapted for associating with the implant, the second section being movable relative to the first section;
- wherein the lumen is adapted to receive the transfer pin and the implant when the transfer pin is associated with the implant.
The device of embodiment 1, wherein the receiver includes a sloped surface.
The device of embodiment 1, wherein the lumen of the receiver is substantially cylindrical.
The device of embodiment 1, wherein the cross-sectional area of the lumen of the receiver varies along a length of the lumen.
The device of embodiment 1, wherein the lumen includes a notch.
The device of embodiment 1, wherein the lumen includes a first relatively narrow and a second relatively wide notch.
The device of embodiment 1, wherein the transfer pin is substantially straight.
The device of embodiment 1, wherein the transfer pin includes at least one curved section.
The device of embodiment 1, wherein the transfer pin includes a shaft and a terminal section including a tip.
The device of embodiment 9, wherein the shaft includes a relatively narrow section and a relatively wide section.
The device of embodiment 9, wherein the transfer pin includes a shoulder or at least one projection.
The device of embodiment 9, wherein the terminal section is substantially conical.
The device of embodiment 1, wherein the transfer pin is substantially conical.
The device of embodiment 1, wherein the transfer pin is adapted to interfit within an aperture of an implant associator.
The device of embodiment 1, wherein the implant comprises a mesh strap or a sling.
The device of embodiment 15, wherein the implant includes a protective envelope at least partially enclosing the mesh strap or a sling.
The device of embodiment 16, wherein the envelope includes two sleeves that cooperate to at least partially enclose the mesh strap or a sling.
The device of embodiment 1, further comprising two handles that are adapted to close relative to one another to effect entry of the transfer pin into the lumen of the receiver.
The device of embodiment 1, further comprising a locking mechanism for releasably locking the first and second sections in at least one predetermined position relative to one another.
The device of embodiment 1, further comprising a separating mechanism for resiliently urging the first and second sections apart.
The device of embodiment 1, wherein at least one of the first and second sections includes at least one curved section.
The device of embodiment 1, further comprising a pivot system operatively connected between the first and second sections.
The device of embodiment 1, further comprising a cam system operatively connected between the first and second sections.
The device of embodiment 1, further comprising a stopper connected to at least one of the first and second sections.
The device of embodiment 1, further comprising:
- a shaft with distal and proximal ends, the first section and the second section being located adjacent the distal end of the shaft;
- and
- a housing located adjacent the proximal end of the shaft.
The device of embodiment 25, further comprising a trigger associated with the housing, the trigger being adapted to effect entry of the transfer pin into the lumen of the receiver.
A system for delivering an implant to an anatomical site in a patient comprising:
- a delivery device including first and second sections, the first section including a receiver having a through-lumen, the second section including a transfer pin;
- and
- an implant, including at least two extensions and a central portion for providing support to an anatomical site in a patient;
- wherein the transfer pin is adapted for associating with the implant.
The system of embodiment 27, wherein the implant includes at least one tanged edge.
The system of embodiment 27, wherein the implant includes at least one non-tanged edge.
The system of embodiment 27, wherein the implant comprises 2, 4, or 6 extensions.
The system of embodiment 27, wherein the implant includes an implant associator associated with at least one extension at an end thereof.
The system of embodiment 31, wherein the implant associator includes a ring with a lumen adapted to receive the transfer pin of the delivery device.
The system of embodiment 31, wherein the implant associator includes one or more wings adapted to impede advancement, at least in one direction, of the implant associator through the lumen of the delivery device.
The system of embodiment 27, wherein the implant includes a protective envelope at least partially enclosing the implant.
The system of embodiment 27, wherein the anatomical site is the sacrospinous ligament or the tendinous arch of the levator ani muscle.
A method for transferring an implant from a second section of a delivery device to a first section of the delivery device, comprising:
- associating the implant with a transfer pin of the second section;
- and
- closing the delivery device such that that the transfer pin and associated implant pass through a lumen of the first section.
The method of embodiment 36, further comprising transferring the implant through a tissue of a patient.
The method of embodiment 37, wherein the tissue is the sacrospinous ligament or the tendinous arch of the levator ani muscle.
A method for securing an implant to an anatomical site in a patient, comprising:
- creating an incision in the pelvic region of a patient;
- associating a second section of a delivery device with the implant;
- inserting the delivery device and the implant into the patient via the incision to a location near the anatomical site;
- and
- transferring the implant or a portion thereof from the second section of the delivery device, through tissue of the patient at the anatomical site, to a first section of the delivery device.
The method of embodiment 39, wherein the implant includes a protective envelope.
The method of embodiment 40, further comprising removing the protective envelope.
The method of embodiment 39, wherein the incision is a vaginal incision.
The method of embodiment 39, wherein the tissue is the sacrospinous ligament or the tendinous arch of the levator ani muscle.
