This disclosure enables various threading devices (e.g., suturing devices) that can sequentially send a plurality of carriers (e.g., needle caps, sleeves) to an object (e.g., animate, inanimate, human tissue, organ tissue, heart tissue) or sequentially receive a plurality of carriers (e.g., needle caps, sleeves) from an object (e.g., animate, inanimate, human tissue, organ tissue, heart tissue). For example, some threading devices can sequentially send some carriers in a relatively rapid succession or some threading devices can sequentially receive some carriers in a relatively rapid succession.

SUTURE DEVICE, TREATMENT DEVICE WITH SUTURE DEVICE, AND TREATMENT SYSTEM
20230165581 · 2023-06-01 ·

The invention provides a suture device, a treatment device with the suture device and a treatment system. The treatment system includes an endoscope and the treatment system. The treatment system is used in cooperation with the endoscope and includes an operating handle and the suture device. The suture device comprises a main shell, a suture needle, a needle feeding assembly and a needle anti-backoff assembly. One end of the suture needle is connected to a suture line, and the other end is a tip. The needle feeding assembly is arranged on the main shell and forms a separable engagement relationship with the suture needle so as to control advancing of the suture needle. The needle anti-backoff assembly is arranged on the main shell and forms a separable engagement relationship with the suture needle so as to prevent the withdrawal of the suture needle.

PURSESTRING SUTURE RETRACTOR AND METHOD OF USE
20220346772 · 2022-11-03 · ·

Systems, devices, and methods for endoscopically retracting a target tissue. The device includes a first shaft and a second shaft slidably coupled thereto. An internal member extends in a transverse direction from the first shaft and is configured for advancement through a penetration in the target tissue to atraumatically engage a distal surface of the target tissue after being advanced therethrough. A pair of external members extend from the second shaft generally parallel to the transverse direction. The external members are spaced apart and are configured to atraumatically engage a proximal surface of the target tissue when the internal member is moved longitudinally relative to the external members. The internal member applies traction to the target tissue when retracted past the pair of external members, which apply counter-traction to the target tissue on opposing lateral sides of the internal member, to re-shape the target tissue and enable subsequent suture placement.

Apparatus and method for minimally invasive suturing

An apparatus and method for minimally invasive suturing is disclosed. A suturing device for minimally invasive suturing includes proximal section having a proximal end, a distal end, and a longitudinal axis therebetween, a suture head assembly extending from the distal end of the proximal section; a suturing needle having a pointed end and a blunt end, the suturing needle capable of rotating about an axis approximately perpendicular to a longitudinal axis of the proximal section, wherein the pointed end of the suturing needle is positioned within the suture head assembly prior to and after rotation of the suturing needle, and an actuator extending from the proximal end of the proximal section to actuate a reciprocating needle drive having a needle driver for engaging and rotating the suturing needle.

System for meniscal repair using suture implant cinch construct

A system for repairing tears in soft tissue, e.g., meniscal tissue, by employing cinch stitching. More specifically, the present invention provides an apparatus for meniscal repair using a suture implant construct. The suture implant construct includes a first and second implant which are connected to each other via a length of suture. The implants are designed to be loaded on external surfaces of the first and second trocars.

Suture-based knotless repair
09820731 · 2017-11-21 · ·

An apparatus including a flexible member with two terminal ends configured to form a single closable loop and at least two fixation members. The first fixation member and the second fixation member are slidably received on the single closable loop formed by the flexible member.

Suturing bead, suturing needle, side suction cap and endoscopic organ suturing implement using same

The present invention relates to a suturing bead, a suturing needle, a side suction cap and to an endoscopic organ suturing implement using same. More specifically, the present invention relates to an endoscopic organ suturing implement comprising a suturing bead which can be naturally rested lying against the organ wall during discharge, a suturing needle by means of which it is possible to control discharge of the suturing bead, and a side suction cap constituted in such a way as to be able to prevent damage to other organs during surgery.

Devices and methods for advancing knots

Embodiments of a knot pusher and methods of use thereof are disclosed, that are usable for pushing a knot formed from a suture, two limbs of the suture extending from the knot. The knot pusher comprises a distal head defining top and bottom walls terminating in a distal knot pushing surface. The distal head includes at least two side grooves defined between the top and bottom walls that extend proximally from the knot pushing surface. Each of these side grooves is operable to receive one of the limbs of suture. The distal head additionally comprises at least one suture guide coupled to the top and bottom walls for guiding the one of the limbs of suture into one of the side grooves.

Wire knot delivery device

Disclosed is a wire knot delivery device, and more particularly, a wire knot delivery device for delivering and maintaining a knot of a medical wire in a medical procedure. The wire knot delivery device includes a first body, a second body parallel to the first body and moving relative to the first body, a first catching part connected to a side of the first body and caught by a side of the knot during the delivery of the knot, and a second catching part connected to a side of the second body and caught by another side of the knot during the delivery of the knot. As the second body moves, a distance between the first catching part and the second catching part is adjusted.
