Abstract: Systems, devices, and methods for treating a glaucomatous eye are provided. An amount of pulsed laser energy is delivered to the pars plana of the eye by a hand-holdable device which comprises a hand-holdable elongate member and a contact member disposed on an end of the elongate member. A contact surface of the contact member is placed in direct contact with the eye so that a reference edge of the contact member aligns with the limbus and a treatment axis defined by the elongate member is angularly offset from the optical axis of the eye. The amount of pulsed laser energy delivered is insufficient to effect therapeutic photocoagulation but is sufficient to increase uveoscleral outflow so as to maintain a reduction from pre-laser treatment intraocular pressure. Amounts of pulsed laser energy will be transmitted to a circumferential series of tissue regions of the eye.

The suture anchor assemblies can be employed in place of or in addition to traditional suture anchors. The assemblies, kits, and methods described herein can be utilized in a variety of procedures and locations in the body where anchoring a graft or tissue adjacent a bone is desired, including, for example, rotator cuff repair and ligament (e.g., the anterior cruciate ligament or ACL) reconstruction and/or repair.

Abstract: A wound closure device for closing a surgical wound includes at least one compressive clip for applying pressure to a patient's tissue. The clip includes a first clamping arm, a second clamping arm, and a flexible pin maintained between the first and second clamping arms in a press-fit relationship. Each of the first and second clamping arms has a proximal first end, an opposing distal second end and a sidewall extending therebetween. The clip has a first position in which the proximal first ends of the first and second clamping arms partially engage or do not engage each other and a second position in which the proximal first ends of the first and second clamping arms pivotally engage each other. In the second position of the clip, a compressive force generated at the proximal first ends is transferred through the first and second clamping arms to the distal second ends.

Abstract: Disclosed herein are devices for improving coaption of the mitral valve leaflets to reduce or eliminate mitral valve regurgitation. The devices may be used to perform mitral valve annuloplasty, or to serve as a docking station for a transcatheter prosthetic heart valve. The various embodiments of devices are configured for percutaneous and, in some cases, transvascular delivery. Delivery systems useful for routing the devices to the mitral valve are also disclosed, including catheters, balloons and/or mechanical expansion systems. The devices themselves include at least one tissue penetrating member. Methods of delivery include partially embedding the devices in the mitral valve annulus via at least one tissue penetrating member. Tissue penetrating members may be embedded into the tissue in a simultaneous or a nearly simultaneous fashion. Upon embedding, the devices employ various expansion and/or contraction features to adjust the mitral valve diameter.

Abstract: A helical stent is provided that is wound in a zig-zag pattern along a pitch angle with respect to a plane transverse to the axis of the stent. A bisecting line extending through a bend and between two adjacent angular struts is also angled with respect to the longitudinal axis of the stent.

Abstract: A device and a method for increasing or restoring a flow in a body lumen are provided. The device and the method may treat conditions like a stroke by removing a clot from a blood vessel and/or reopen the vessel. The device may have a plurality of engaging elements, wires that can link at least two engaging elements, a central wire, and proximal control element. The positions of the engaging elements and the distance there between can be adjusted to ensure the engagement of the clot or occlusion.

Abstract: A device 10 for repairing mitral valve leaflets 2, 3 includes a jaw mechanism 15 that may be positioned adjacent a mitral valve leaflet 2, 3. The jaw mechanism 15 may move between an open position and a closed position by pivoting a first jaw relative 16 to a second jaw 18. The first jaw 16 may include a rivet 28 that may move from a stored position to an application position projecting away from the first jaw 16 when the jaw mechanism 15 is moved from the closed to the open position. Closing the jaws 16, 18 about a valve leaflet 2, 3 causes the rivet 28 to pierce the leaflet. The jaw mechanism 15 may then be rotated to wind the leaflet 2, 3 thereabout and again pierce the leaflet. The rivet 28 may then be released from the jaw mechanism 25 and the device 10 removed from the patient.

Abstract: A stent delivery system can include a core member, a stent, and a stent engagement member. The engagement member can be positioned along a distal segment of the core member and be coupled to the core member. The engagement member can have an outer surface.
