A clip device for hemostasis includes a clip having a proximal end portion and at least two arm portions extending from the proximal end portion and provided with a tendency to open. A sliding ring is provided for closing the arm portions of the clip. A first retainer is attached to the clip, and the first retainer is configured to be releasably secured to a second retainer that may be attached to an operating wire or a torque cable. In operation, the clip device is advanced to a target site in a body cavity. An outer sheath is retracted to expose the clip, causing the arms to open. An inner sheath is advanced distally, causing the sliding ring to advance distally to close the arms of the clip. Stop elements may be disposed on the clip to ensure that he sliding ring is not advanced distally over the clip. Then, the first retainer is disengaged from the second retainer. Various mechanisms are disclosed to permit the first and second retainers to disengage from one another. The first retainer, attached to the clip, is left inside the patient's body cavity, while the second retainer is removed from the patient.

A multi-clip device for hemostasis includes an introducing tube (outer sheath) insertable into a body cavity. An operating wire is disposed within the introducing tube, and is advanceable and retractable within the introducing tube. A plurality of detachable clips are arranged in a serial fashion within the introducing tube. Each clip has an engagement portion at the proximal end thereof and a plurality of arms extending towards the distal end thereof. The distal end of the operating wire engages the engagement portion of the proximal most clip, and the arms of the proximal most clip engage the engagement portion of the adjacent distally located clip. An expandable collar is slidably disposed about the arms of the clip and is configured such that when the collar is moved distally over the arms it closes and holds them in a closed position. The expandable collar has an expanding portion that is engaged by the distal end of the introducing tube so that the introducing tube can be used to advance the collar distally relative to the clip.

A clip device delivery apparatus for hemostasis has an introducer tube, such as an endoscope or sheath having a distal end portion and working channel receiving an operating wire detachably securing a clip device comprising tissue engaging arms and a sliding ring for closing the arms. A protective cap having a tube mounting section and a distal section having a receiving chamber define a passageway therebetween, the mounting section being mounted to the introducer tube distal end portion and the distal section receiving tissue and clip arms to close about tissue. The operating wire and clip device are inserted within the working channel. Methods of grasping tissue are provided using the introducer tube introduced endoscopically into a patient, tissue suctioned and clip arms deployed into tissue receiving chamber, sliding ring moved distally to close the clip arms about the tissue, and the clip detached from the operating wire.

A clipping device comprises: a clip loaded into a forward end portion of a sheath; a manipulating wire connected to a rear end of the clip; and a retention ring fitted onto the clip and fitted into the sheath so as to be capable of advancing and retreating. The retention ring includes: a resin retaining portion which has two or more skirt portions which, when being situated inside the sheath, are closed inwardly by being pressed by an inner wall of the sheath and which, when being situated outside of a forward end of the sheath, are opened in a width larger than an inner diameter of the sheath to prevent retreat into the sheath, and a metal clamping portion arranged on a forward end side of the retaining portion and, when being situated on a forward end side of the clip, abutting the clip to clamp it.

The present invention relates to a safety clip device for shielding and retaining a tip of an introducer needle following insertion of a vascular catheter. The safety clip device includes a sleeve having an interlock system for locking together the sleeve and the catheter adapter. The sleeve houses a safety clip wherein a portion of the introducer needle extends through the safety clip and is pinched between arm portions of the safety clip. As the tip of the introducer needle is withdrawn from the catheter adapter, the tip of the introducer needle is retained in the safety clip, whereafter the safety clip is retained within the sleeve and the sleeve is released from the catheter adapter for safe disposal.

A vascular closure device comprising a retrievable sheath-delivered contractible, clip device with structural radial or terminal members with terminal and non-terminal hooks that engage the vessel wall. Unlike other vascular closure clips, this device is delivered on the outside rather than the inside of sheath. Closure of the tissue opening can be effected by the feet of the clip engaging the puncture, aperture, or wound edges and memory characteristics of the device cause a contraction of the members, bringing the members into apposition and the wound edges together, permitting immediate vascular closure and healing of the blood vessel. The device can be delivered and recovered by an intravascular sheath.

A medical device includes a handle, a flexible member extending from a proximal end connected to the handle to a distal end, a rotation mechanism connected to the distal end of the flexible member, an end effector coupled to a distal portion of the rotation mechanism and a push member extending through the handle and flexible member and connecting to the rotation mechanism, the rotation mechanism being configured and dimensioned to convert axial movement of the push member into rotation of the end effector.

A forceps of endoscope comprises a clip that is provided with at least three arms and a base end portion. The arms are connected to the base end portion. Each of the arms has an open-close deforming portion located close to the base end portion. A core member is provided inside the clip to be in contact with an inner surface of the open-close deforming portion at least when the arms are open. A clip open-close ring is operated by remote control performed from the base end of the sheath. The clip open-close member is engaged with the open-close deforming portion to open and close the arms with a substantially equivalent angular interval and so as to prevent each of the arms from crossing each other.

A novel occluder application and clip device for treatment of embolic stroke caused by atrial fibrillation uses multiple sutures in a non directional handle to affix the occlusion device to the applicator and manipulate the occluder from an open and receiving position to a closed and occluding position. The occluder is retained in place by a clamping means related to locks retainers, resilient material or otherwise. An actuator mechanism is used to manipulate the occluder to a locked or occluding position. The applicator with the occluder attached has a low profile and remote manipulations to allow the occluder to be delivered to the clamping location within a patient through a small incision or delivery port such as a trocar cannula or the like.
