Abstract
Systems and method for delivery and positioning of a sheet-like surgical implant to a target site including a means of deploying and orienting the sheet-like implant within the body.
Core Innovation
The invention relates to a delivery system for delivering a sheet-like implant to a surgical site. The system includes a delivery tube having a lumen, an elongate shaft slideably positioned through the lumen, and a handle assembly coupled to the proximal end of the delivery tube to selectively actuate the elongate shaft relative to the delivery tube. A pair of deployment arms is attached to a distal end of the elongate shaft, and the sheet-like implant is coupled to the pair of deployment arms.
Manipulation of the handle assembly causes translation of the elongate shaft within the lumen to deploy the deployment arms from the distal end of the delivery tube, with the sheet-like implant spanning between the deployment arms. In resilient and compressible embodiments, the pair of deployment arms is resiliently biased to an open configuration wider than the lumen of the delivery tube and compressible to a closed configuration in which the deployment arms are disposed within the lumen. The sheet-like implant is in a folded configuration within the lumen and is spread to an unfolded configuration upon deployment of the deployment arms.
A fluid delivery channel extends through the delivery tube or the elongate shaft to the distal end to dispense fluid onto the sheet-like implant spanning between the pair of deployment arms. A syringe is connectible to the proximal end and is in fluid communication with the fluid delivery channel. The method aspects include advancing the delivery system to a surgical site, manipulating the handle assembly to deploy the pair of deployment arms and spread the sheet-like implant to an unfolded configuration, manipulating the syringe to dispense fluid from the distal end of the fluid delivery channel onto the sheet-like implant, and attaching the sheet-like implant to body tissue within the surgical site.
Claims Coverage
The partial content includes three independent claims: clm-00001, clm-00010, and clm-00018. Across these independent claims, the core inventive features focus on a tube-and-slideable-shaft delivery architecture with handle-actuated translation, resiliently expandable deployment arms that carry and spread a sheet-like implant, and an integrated fluid delivery channel with syringe dispensing onto the deployed implant, followed by attaching the implant to body tissue.
Handle-actuated slideable elongate shaft deploying sheet-like implant
A delivery system comprising a delivery tube with a lumen; an elongate shaft slideably positioned through the lumen; a handle assembly coupled to the proximal end of the delivery tube for selectively actuating the elongate shaft; a pair of deployment arms attached to a distal end of the elongate shaft; and a sheet-like implant coupled to the pair of deployment arms, wherein manipulation of the handle assembly causes translation of the elongate shaft within the lumen to deploy the pair of deployment arms from the distal end with the sheet-like implant spanning between the pair of deployment arms.
Resiliently biased deployment arms with folded-to-unfolded implant spreading
A delivery system wherein the pair of deployment arms is resiliently biased to an open configuration wider than the lumen of the delivery tube and compressible to a closed configuration in which the pair of deployment arms are disposed within the lumen; wherein the sheet-like implant is in a folded configuration within the lumen of the delivery tube and upon deployment of the deployment arms, the sheet-like implant is spread to an unfolded configuration.
Syringe-dispensed fluid onto deployed sheet-like implant via fluid delivery channel
A delivery system including a fluid delivery channel extending through the delivery tube to the distal end of the delivery tube; a syringe connectible to the proximal end of the handle and in fluid communication with the fluid delivery channel; and wherein manipulation of the syringe causes fluid to be dispensed from the distal end of the fluid delivery channel onto the sheet-like implant spanning between the pair of deployment arms.
Method of deploying sheet-like implant and attaching to body tissue using syringe-dispensed fluid
A method comprising manipulating the handle assembly to deploy the pair of deployment arms with the sheet-like implant spanning between the pair of deployment arms, wherein upon deployment of the pair of deployment arms, the sheet-like implant is spread to an unfolded configuration; manipulating the syringe to dispense a fluid from the distal end of the fluid delivery channel onto the sheet-like implant spanning between the pair of deployment arms; and attaching the sheet-like implant to body tissue within the surgical site.
Across the independent claims, the inventive coverage centers on a handle-actuated, slideable elongate shaft within a delivery tube that deploys a pair of deployment arms carrying a sheet-like implant. In resilient embodiments, the deployment arms move from a closed, lumen-contained configuration to an open configuration while spreading a folded implant to an unfolded state. The system further includes a syringe-connected fluid delivery channel that dispenses fluid onto the deployed implant, and the method culminates in attaching the sheet-like implant to body tissue, with dependent refinement limiting the fluid to a tissue adhesive.
