Methods, systems and devices for endometrial ablation. In accordance with a method, a working end of an RF ablation device is positioned in a patient uterus to contact endometrial tissue, the working end comprising a dielectric wall capable of non-expanded and expanded shapes. An indicator mechanism is operatively coupled to the wall and configured to indicate non-expanded and expanded shapes of the wall.

Methods and systems for endometrial ablation utilizing radio frequency

An apparatus for sealing a puncture through a vessel wall including a positioning assembly, a sheath releasably engaged with the positioning assembly, and a support member axially advanceable through the sheath. The positioning assembly includes a positioning element positioned at a distal portion of the positioning assembly and a sealant disposed at a distal portion of the positioning assembly. The sheath guides the sealant and positioning assembly to the puncture in the vessel wall.

Apparatus and methods for sealing a vascular puncture

Sheath adapter

A closure system for delivering a sealant to an arteriotomy. A distal section of the closure system can include overlapping inner and outer sleeves that can expand with expansion of the sealant. A proximal section of the closure system can include a handle portion and a sheath adapter extending from the handle portion. The handle portion can comprise one or more actuators that when depressed or engaged can assist in deployment of the sealant in the arteriotomy and can further include tamping of the sealant and/or retraction of an expandable member. The sheath adapter can removably engage a side port or an irrigation line of a standard procedural sheath. When the sheath adapter is secured to the procedural sheath, movement of the closure system can also move the procedural sheath.

A method of reducing the risk of clinical sequelae to catheter induced vascular injuries may include introducing a guide wire into a vascular sheath residing in a blood vessel, proximally retracting the vascular sheath while leaving the wire in place, and observing indicia of the presence or absence of a vascular injury caused to the blood vessel by the vascular sheath or a procedural catheter previously advanced through the vascular sheath. If indicia of a vascular injury are observed, the method may further involve proximally retracting the guide wire to position the inflatable balloon adjacent the injury and inflating the balloon to reduce blood flow past the injury, while leaving the guide wire in place to provide subsequent access to the injury. The inflatable balloon can be inflated and deflated through a valve positioned at the proximal end of the guide wire.
