An electro-surgical bipolar forceps includes a first tip and a second tip, each having a body. The body has a distal end and a proximal end. The body has a first groove having a substantially planar base proximate the proximal end. A substantially planar face is proximate to the distal end of the tip body. The base and the face on each tip define planes that are approximately perpendicular with respect to each other. A tip assembly includes a tip and an engagement plug. When making the tip assembly, a planar surface on the engagement plug is aligned with the planar base of the groove in the tip. Then the tip is connected to the engagement plug.

Systems, devices and methods for occluding the left atrial appendage (LAA). The device excludes the LAA from blood flow. The implantable device is delivered via transcatheter delivery into the LAA and secured within the LAA. The implant comprises an expandable and compliant frame and an expandable and conformable tubular foam body. A delivery and tether retraction system includes a handle for controlling a pusher and tether. The pusher may be moved a distance away from the implant without changing the orientation of the implant, while the tether is still attached to the implant. Severing the tether and proximally retracting a control on the hand piece by a distance causes the severed end to advance distally by at least about twice that distance. A loader includes a conical portion with guides and a reservoir for submerging the foam prior to loading and delivery.

A surgical instrument includes a housing, a shaft extending from the housing, and an end effector assembly that is disposed at a distal end of the shaft. The end effector assembly includes a tubular portion, a connection arm, and a toolbox. The tubular portion defines a lumen and the connection arm is extendable from the lumen. The toolbox has a micro-tip that is configured to be selectively secured to a connection tip of the connection arm. The toolbox has a transport configuration where the toolbox is disposed within the lumen and a deployed configuration where the toolbox is disposed entirely outside of the lumen.

Aspects of the present disclosure include a surgical device comprising electrodes on the sides of an end of an effector to aide in sealing during various surgical procedures, such as a liver resection. During a sealing procedure, the surgeon may wipe the surgical site with the end effector, causing the electrodes to touch the fractured area. Electrosurgical energy may be applied to the electrodes during the wiping, causing coagulation of smaller vessels, such as tiny blood vessels and bile ducts in the parenchyma of the liver. In some cases, due to the nature of some smaller vessels, electrosurgical energy should be delicately applied to cause sealing but to avoid overly damaging the remaining tissue. In some embodiments, the thin design of the electrodes allows for an appropriate amount of electrosurgical energy to be applied to the fractured area.

The invention concerns a multifunctional electrosurgical device for treating biological tissues comprising a first member and a second member linked by a hinge allowing the members to be moved together and apart from each other; the first member comprising, at the front end of same, a first electrode for forming a first electrical contact with the tissues and the second member comprising, at the front end of same, a second electrode for forming a second electrical contact with the tissues. The first electrode has a concave cross-section, capable of partially housing the second electrode and of making the second electrode protrude from the first electrode when the two members are moved together. The device is remarkable in that the electrodes are configured to allow the formation of the first electrical contact on the outer surface of the first electrode and the formation of the second electrical contact on the protruding part of the second electrode.

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a catheter for use in cardiac mapping and/or ablation. The catheter may include an elongate catheter shaft having a distal ablation electrode region capable of ablating tissue. An electrode assembly may be coupled to the distal ablation electrode region. The electrode assembly may include a flexible circuit having one or more electrodes disposed thereon.

A forceps includes an end effector assembly including first and second jaw members. One or both of the jaw members is movable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One or both of the jaw members is configured to conduct energy between the jaw members and through tissue grasped therebetween to treat tissue. An insulative tubular member is movable relative to the end effector assembly between a retracted position, wherein the insulative tubular member is positioned proximally of the end effector assembly, and an extended position, wherein the insulative tubular member is disposed about the end effector assembly. A monopolar member is configured to apply energy to tissue to treat tissue when the insulative tubular member is disposed in the extended position.
