Apparatus and methods are provided for treating a tissue opening, for example a trocar opening used in a minimally invasive surgical procedure. In a tissue closure device, a finger guard or shield can be used, handle or holding area or areas can be used, and positioning indicators can be used. A resiliently flexible target material can also be used for reliably holding a suture during the procedure. Introducers can be used having a suture holder, an alignment indicator and insertion limits.

Apparatus and methods for tissue closure

An apparatus and method for capturing material within a body lumen are disclosed. The apparatus includes a core wire extending from a proximal end to a distal tip, an actuator member defining a lumen for receiving at least a portion of the core wire, and a distal basket having a distal enclosed end fixed relative to the core wire and one or more elements extending from a proximal open end to a collar slidable on the core wire. The collar is slidable on the core wire within an interior of the distal basket such that, when the collar contacts the actuator member, the collar applies an inward force to direct the proximal open end of the distal basket radially inwardly.

Retrieval apparatus and methods for use

An apparatus is provided that is operable in different modes to perform various functions for treating a body lumen. The apparatus includes a shaft including proximal and distal ends, a lumen extending there between, and a balloon on the distal end. The apparatus includes a valve on the distal end that selectively opens or closes an outlet communicating with the lumen. With the valve open, fluid introduced into the lumen exits the outlet into a body lumen. With the valve closed, fluid introduced into the lumen expands the balloon. The valve may be biased to be closed, e.g., by a spring element disposed within the balloon. Optionally, the apparatus also includes an actuator for expanding a helical member within the balloon interior, e.g., either before or after expanding the balloon, such that the helical member and balloon may adopt an expanded helical shape for removing material within a body lumen.

Apparatus and methods for treating obstructions within body lumens

An apparatus and method are provided for accessing and/or removing material from a body lumen. The apparatus includes a tubular sheath including a shaft having a proximal end and an expandable distal end that is expandable between a collapsed configuration and an expanded, tapered configuration. A treatment member can be introduced into the body lumen through the tubular sheath. The treatment member includes one or more expandable members to interact with the material to be removed from the body lumen.

Apparatus and methods for accessing and removing material from body lumens

A surgical ligation clip and method of operation are described and include a top jaw member and bottom jaw member joined at a hinge section for movement about the hinge section. The hinge section can be offset or space laterally from one or both of the jaw members. Teeth arrangements and distributions are also described, as well as closing and jaw ends engagement configurations, for example for more easily engaging/piercing connective or other tissue.

Ligation clip

Apparatus and methods are provided for removing obstructive material within a body lumen. The apparatus includes a macerator device deployable from a sheath that includes an expandable cage carried by a shaft and within a constraint tube. The shaft is movable relative to the constraint tube for deploying and expanding the cage within a body lumen such that an open end of the cage is oriented towards obstructive material. The cage is advanced to capture the material or the material is directed into the cage using an expandable member expanded beyond the material and retracted to direct the material into the cage. The cage is withdrawn into the constraint tube to compress the cage radially inwardly. Materials extending through apertures in the cage are sheared off by a sharpened edge of the constraint tube. The smaller, sheared off particles are then aspirated from the body lumen through the sheath.

Flow restoration systems and methods for use

A method for removing material within a body lumen of a patient is disclosed. The method include introducing a distal end of a tubular member into a body lumen. The tubular member has a guide member extending distally from the distal end. Next, the tubular member is positioned such that the distal end is disposed adjacent material to be removed and a distal tip of the guide member is disposed beyond the material. One or more lumen clearing elements are then deployed from the distal tip of the guide member. Each lumen clearing element includes an expandable structure that expands from a contracted condition within the guide member to an expanded condition when deployed from the distal tip. Then, the deployed one or more lumen clearing elements are retracted along a track of the guide member to engage the material disposed adjacent the distal end of the tubular member and draw the material into a lumen of the tubular member.

In a tissue closure device, a finger guard or shield can be used, handle or holding area or areas can be used, and positioning indicators can be used. A resiliently flexible target material can also be used for reliably holding a suture during the procedure. The resiliently flexible target material may be included as part of a removable mating component for use with a movable wing. Introducers can be used having a suture holder, an alignment indicator and insertion limits.

Flared stents are disclosed, and apparatus and methods for delivering such stents into a bifurcation between a main vessel and a branch vessel. The stent includes a first tubular portion a second flaring portion that may be flared radially outwardly to contact the ostium. The stent may include variable mechanical properties along its length. The stent may be delivered using a catheter including proximal and distal ends, the stent overlying first and second balloons on the distal end. During use, the catheter is advanced through an ostium into the branch to place the stent within the branch. The first balloon is expanded to flare the stent to contact a wall of the ostium, thereby causing the stent to migrate partially into the ostium. The second balloon is expanded to fully expand the stent within the ostium and branch.

Flared stents and apparatus and methods for delivering them

An apparatus is provided for removing material within a body lumen that includes a catheter including a proximal end, a distal end for introduction into a body lumen, and an aspiration lumen extending therebetween; a guide member extending from the distal end and terminating in a distal tip, the guide member comprising a track adjacent a track lumen extending from the distal tip into the aspiration lumen; and an obstruction clearing device deployable from the guide member and retractable along the track. In addition or alternatively, the apparatus includes a cutting head reciprocable within the aspiration lumen adjacent the distal end for macerating material being aspirated into the aspiration lumen.
