Multifunctional devices having loop configured portions and collection systems for endoscopic surgical procedures and methods thereof
| Details |
Inventors: Yoon, InBae;
Assignee:
Primary Examiner: Willse; David H.
Assistant Examiner: Polutta; Mark O.
Attorney, Agent or Firm:
A multifunctional device for use in endoscopic operative procedures includes a loop forming portion for being introduced in the body and being movable, from externally of the body, from a non-deployed position to a deployed position to form a loop structure for performing various functions including collecting substances. The loop forming portion is squeezable to squeeze collected substances into a collection bag prior to withdrawal of the loop forming portion from the body. The collection bag is movable between a non-expanded position facilitating introduction in the body and an expanded position within the body to receive the loop forming portion. A method of facilitating the performance of endoscopic procedures includes the steps of introducing the loop forming portion in the body through a narrow portal, moving the loop forming portion from the non-deployed position to the deployed position, performing an operative procedure with the loop forming portion and moving the loop forming portion to the non-deployed position for withdrawal from the body. |

DETAILED DESCRIPTION Accordingly, it is a primary object of the present invention to improve the efficacy and safety of endoscopic operative procedures.
Another object of the present invention is to expand the types of procedures that can be performed endoscopically.
An additional object of the present invention is to facilitate endoscopic procedures with a multifunctional device having a portion capable of being deployed in a loop configuration upon introduction of the portion in the body to perform various diverse functions.
It is also an object of the present invention to provide a method of facilitating the performance of endoscopic procedures including the steps of introducing a loop forming portion of a multifunctional device in the body in a non-deployed position and moving the loop forming portion, from externally of the body, to a deployed position forming a loop configuration.
Another object of the present invention is to facilitate endoscopic procedures with a collection system having a collection bag for being introduced in the body through a narrow portal to allow substances to be placed in the interior of the collection bag for removal from the body.
Some of the advantages of the present invention include improved visibility in endoscopic procedures, reduced need for insufflation, improved exposure of operative sites, protection of surrounding tissue and organ structure, irrigation and/or aspiration or drainage, cleansing of debris, stones, pus and other substances, such as fluids released by a ruptured appendix, bowel or cyst, allowing expansion of an absorbent material to greater sizes within the body, facilitating introduction and withdrawal of the devices through a narrow portal, reducing or preventing the undesirable release into the body of substances collected by the multifunctional devices, collecting substances within the body and miniaturizing the collected substances simultaneously and withdrawing collected substances from the body.
These and other objects, advantages and benefits are realized with the present invention as characterized in a multifunctional device for use in endoscopic procedures in the body including an elongate outer member, an elongate inner member and a loop forming portion connected between the outer member and the inner member for being introduced in the body
