Methods, apparatuses and systems are described for stent delivery and positioning to cover an access site. A stent delivery system may include a tubular member configured to advance through an access site and a primary constrainment member configured to releasably couple the stent to the tubular member. The stent delivery system may further include a secondary constrainment member at least partially disposed around the primary constrainment member, the stent, and the tubular member. In some cases, the tubular member and the primary constrainment member may be configured to reposition the stent within the body lumen after removal of the secondary constrainment member such that at least a portion of the stent covers the access site after withdrawal of the tubular member, the primary constrainment member, and the secondary constrainment member from the body lumen through the access site.

Apparatuses for stent delivery and positioning to cover an access site

Methods, apparatuses and systems are described for expandable stent delivery apparatus to cover an access site. The method may include delivering a stent delivery system through an access site, where the stent delivery system comprises a positioning member with a first portion that is rotatable with respect to a second portion, and where the stent is releasably coupled with the first portion of the positioning member. In some cases, the method may further include withdrawing an outer constrainment member front the stent to deploy a proximal portion of the stent within the body lumen and rotating the proximal portion of the stent away from the access site by withdrawing the positioning member proximally and back through the access site. The method may further include covering the access site with the proximal portion of the stent upon fully deploying the proximal portion from the outer constrainment member.

Rotatable stent delivery apparatus to cover access site

Methods, apparatuses and systems are described for stent delivery and positioning to cover an access site. The method may include delivering the stent through an access site in a wall of the body lumen. In some cases, the method may include repositioning the stent within the body lumen to at least partially cover the access site with the stent. The stent may be repositioned within the body lumen by retracting the stent towards the access site such that a proximal portion of the stent at least partially covers the access site. The stent may then expand within the body lumen. In some cases, the stent may expand within the body lumen by releasing a primary constrainment member from the stent by pulling the primary constrainment member in a proximal direction away from the stent.

A catheter for performing a procedure at a treatment site in the lumen of a blood vessel. The catheter includes an elongate tubular shaft having a proximal bend, a distal bend and a hinge element. A distal portion of the shaft includes a window extending through the sidewall of the shaft between the hinge element and the distal end of the elongate tubular shaft. A working element is disposed within the lumen of the elongate tubular shaft and is configured for performing the procedure through the window at the treatment site. The bends and hinge element are configured to urge the window against a wall of the vessel at the treatment site.

Method for manipulating catheter shaft

The various embodiments simplify the delivery of an occlusive implant to a hollow anatomical structure, such as a fallopian tube. For example, the delivery devices don't need to be retracted manually to deploy the implant. When the devices are activated, stored energy or a powered drive member induces movement of the various components. The operator need only position the distal ends of the devices at the treatment site and then commence deployment by, for example, flipping a switch or changing the position of an activation button. The present embodiments thus increase the efficacy of occlusion procedures by reducing the likelihood of operator error.

Devices and methods for manipulating a catheter shaft

The systems and methods described herein provide for the improved three-dimensional imaging of the an internal body lumen of a living being. A medical imaging system is provided which can include an image processing system and a medical imaging device. The medical imaging device can be insertable into the internal lumen and can include an image acquisition system configured to image the lumen and detect the position and orientation of the image acquisition system within the lumen. The image acquisition system can output the image, position and orientation data to the image processing system to be used by the processing system to generate and display a virtual three-dimensional image of the internal lumen to the user. The user can use various software tools provided by the image processing system, such as distance and area measuring tools, to interact with the image.
