摘要:
Apparatus for manipulating and securing tissue are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably disposed through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. The stabilizing members can be adapted to become angled relative to a longitudinal axis of the elongate tubular member. Moreover, one or all the articulation controls and functions can be integrated into a singular handle assembly connectable to the tissue manipulation assembly via a rigid or flexible tubular body.

Multi-position tissue manipulation assemblies are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably disposed through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. One or all the articulation controls and functions can be integrated into a singular handle enclosure connectable to the tissue manipulation assembly via a rigid or flexible tubular body. A needle deployment mechanism may be positioned within the enclosure. Such a mechanism can have multiple positions adapted to lock and/or advance a needle assembly within the enclosure in a controlled manner as well as for deploying the anchor assembly.
摘要:
Apparatus and methods are provided for forming a gastrointestinal tissue fold by engaging tissue at a first tissue contact point and moving the first tissue contact point from a position initially distal to, or in line with, a second tissue contact point to a position proximal of the second contact point, thereby forming the tissue fold, and extending an anchor assembly through the tissue fold from a vicinity of the second tissue contact point. Adjustable anchor assemblies; as well as anchor delivery systems, shape-lockable guides and methods for endoluminally performing medical procedures, such as gastric reduction, treatment of gastroesophageal reflux disease, resection of lesions, and treatment of bleeding sites; are also provided.

Removable apparatus and methods for manipulating and securing tissue are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have tissue stabilizing members adapted to stabilize tissue therebetween, an engagement member slidably disposed through the stabilizing members and having a distal end adapted to engage tissue, and a delivery tube pivotable about the tissue stabilizing members. The tissue manipulation assembly optionally may be configured for removable attachment to an endoscope.

Self-locking removable apparatus and methods for manipulating and securing tissue are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have tissue stabilizing members adapted to stabilize tissue therebetween, an engagement member slidably disposed through the stabilizing members and having a distal end adapted to engage tissue, and a delivery tube pivotable about the tissue stabilizing members. The tissue manipulation assembly optionally may be configured for removable attachment to an endoscope.

Interlocking tissue anchor apparatus and methods are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably disposed through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. Anchor assemblies can be delivered via the tissue manipulation assembly into or through the tissue. The anchors can incorporate various temporary interlocking features or spacing elements between one another to ensure that an anchor is not prematurely ejected from the needle assembly. This allows the anchor assembly to be advanced distally as well as withdrawn proximally within a deployment sheath while avoiding inadvertently ejecting an anchor.
