A transluminal sheath is advanced transseptally into a left atrium of the subject. A distal end of a surrounding-sheath, having an anchor disposed therein, is advanced via a distal end of the transluminal sheath, into a left ventricle of the subject via a commissure of the mitral valve. While the distal end of the surrounding-sheath is in the left ventricle, the surrounding-sheath is pulled proximally with respect to the anchor to expose the anchor. While the distal end of the surrounding-sheath is in the left ventricle, mitral valve tissue that is within the left ventricle is encircled by helically wrapping the anchor around the mitral valve tissue. Subsequently, the surrounding-sheath is extracted from the heart. Other embodiments are also described.

An endovascular apparatus takes the form of an expandable tubular body having a retriever, which may include a pair of interconnected hooks. The retriever may be formed from a single piece of material forming the tubular body, and in the case of a pair of hooks thus has a thickness corresponding to approximately twice the wall thickness of the tubular body. The innermost radial portion of the hooks may be offset from a central axis of a lumen formed by the tubular body, which facilitates free insertion of a balloon or the like for purposes of expanding the tubular body. Related methods of manufacturing an endovascular apparatus with a retriever are also described herein.

A medical arrangement for introducing an object, such as an implant into an anatomical target position comprises a first introducer, a guide wire and a guiding catheter). The guide wire is configured to be introduced before the guiding catheter and object into or towards the anatomical target position. The guiding catheter is configured to be delivered into the position along the guide wire, after which the guide wire is configured to be retracted. The object is configured to be delivered inside the guiding catheter after the guide wire is retracted.

A medical arrangement for introducing an implant into an anatomical target position comprises a first introducer and a guide wire. The guide wire is configured to be introduced before the implant into or towards the anatomical target position. The implant is configured to be delivered along the guide wire into the anatomical target position. The guide wire is configured to be retracted after the implant has been introduced into said anatomical target position so that said object essentially maintains the shape taken when introduced into said anatomical target position.

A needle system for providing fluidic and/or instrument access to an internal body structure. Exemplary embodiments may include non-linear needles having anatomically appropriate lengths and curvatures. Some exemplary embodiments may include a pivotable base, which may assist in stabilizing the needle system with respect to a body structure and/or may be reconfigurable into a safety guard position. Exemplary needle systems may include expandable conduits providing fluidic and/or instrument pathways into internal body structures.

Provided is a ureteral stent including a bladder portion positioned in a bladder of a patient, a kidney portion positioned in a kidney and ureteral passageway of the patient, and one or more tethers coupling the bladder portion to the kidney portion. The ureteral stent allows urine to pass around a blockage, and allows a ureter orifice connecting the ureteral passageway to the bladder to move between a compressed state and an uncompressed state to prevent or minimize urinary reflux, flank pain, blood in the urine, etc., while allowing the bladder portion to move freely in the bladder to prevent the bladder portion from irritating the trigone muscle.

An implantable artificial capsule and a method of implantation are provided. The implantable artificial capsule has a ring with a central opening to accommodate an intraocular lens and at least three haptic arms extending substantially orthogonal from the outer surface of the ring. Each arm has transcleral anchors for sutureless scleral fixation. Upon implantation of the implantable artificial capsule the arms are externalized trans-sclerally and atraumatically. The arms sit subconjunctivally. The implantable artificial capsule does not have any sutures for fixation and is suturelessly implanted in an eye, which is a major advantage as it significantly reduces complications during surgery and recovery.

Soft tissue grafts, packaged soft tissue grafts, and methods of making and using soft tissue grafts are disclosed. One soft tissue graft includes processed tissue material having first and second opposed surfaces. The first and second opposed surfaces are bounded by first and second edges. The first edge has a concave shape that curves toward the second edge. The second edge has a convex shape that curves away from the first edge. The first surface comprises a plurality of apertures. At least one of the apertures is formed from a multi-directional separation in the first surface. One method of making a soft tissue graft includes positioning a cutting die on a surface of tissue material, pressing the cutting die into the tissue material to cut the tissue material, and processing the cut tissue material to create processed tissue material.

The embodiments disclosed herein relate to a ureteral stent having two stent bodies and a tether. The stent can minimize or prevent migration of the device out of the bladder of the patient while also reducing patient discomfort associated with such stents.
