Delivery devices for delivering a self-expanding prosthetic heart valve

Delivery devices for delivering a self-expanding prosthetic heart valve are disclosed. The delivery device includes at least one cord is configured to selectively cinch the self-expanding prosthetic heart valve. The delivery device further includes at least one self-expanding release pin comprising a proximal segment, a distal segment, and an intermediate segment positioned between the proximal segment and the distal segment. The at least one self-expanding release pin includes a normal, expanded condition wherein the intermediate segment extends radially outward relative to a central axis of the spindle from the proximal segment to the distal segment. The delivery device further includes a capsule configured to be distally extended relative to the spindle to collapse the at least one self-expanding release pin from the normal, expanded condition of the at least one self-expanding release pin to a collapsed condition of the at least one self-expanding release pin.

Transcatheter prosthetic heart valve delivery system with lateral offset control

Delivery devices for a stented prosthetic heart valve. The delivery device includes a spindle, at least one cord, and a lateral control feature. The cord is tensioned to crimp the prosthesis to a compressed condition for delivery to a target site. Tension is lessened to allow the prosthesis to self-expand. In a tethered and expanded state in which the prosthesis has self-expanded and is connected to the spindle by the cord, the lateral control feature directs the spindle to a prescribed location relative to the prosthesis appropriate for a functional evaluation of the prosthesis. In some embodiments, the spindle is directed to a center of the prosthesis; in other embodiments, the spindle is held at a commissure of the prosthesis. The lateral control features of the present disclosure assume numerous forms.

Methods and devices for anchoring a gastroenterologic sleeve

A gastroenterologic sleeve is anchored within the digestive tract, without tissue-puncturing mechanisms, by providing anchoring mechanisms that utilize the inherent shape of the stomach to prevent sleeve migration. In at least two embodiments, the anchoring mechanism expands to conform to the interior stomach walls. In other embodiments, internal pessary rings are held in place at the gastroesophageal junction by an external band. A delivery device is provided for implanting the various device transesophageally.

Stent delivery system

An apparatus for delivery and deployment of an expandable stent within a vessel, the apparatus comprising: a) a catheter having a proximal end, a middle portion, a distal end and a catheter shaft b) an expandable stent, expandable from a delivery diameter to a deployment diameter, the stent being coaxially mounted on the distal end of the catheter for expansion thereof; c) securement means coaxially mounted on the catheter near its distal end, distal the middle portion, and over the stent, said securement means comprising: i) a securement sheath having a proximal end, a distal end, an exterior surface and an interior surface, said securement sheath being slidable mounted on the catheter shaft and being constructed and arranged for proximal retraction along the catheter shaft to expose the stent, the securement sheath having a plurality of flexibility enhancing elements, the plurality of flexibility enhancing elements being dispersed substantially throughout the securement sheath

Systems and methods for protecting the cerebral vasculature

Vascular filters and deflectors and methods for filtering bodily fluids. A blood filtering assembly can capture embolic material dislodged or generated during an endovascular procedure to inhibit or prevent the material from entering the cerebral vasculature. A blood deflecting assembly can deflect embolic material dislodged or generated during an endovascular procedure to inhibit or prevent the material from entering the cerebral vasculature.

Methods and devices for endoscopically creating an anastomosis

A method and devices that endoscopically create an anastomosis between two sections of the digestive tract, thereby allowing at least some chyme to bypass a section of the digestive tract while, optionally, the remaining chyme passes through the entire tract.

Incisionless gastric bypass method and devices

A system and method for endoscopically forming an anastomosis between two naturally adjacent points in the digestive tract. The system and method utilizes elongate magnetic devices that, when connected across a tissue boundary, necrose tissue until an anastomosis forms and the devices are passed naturally. Despite the elongate shape of the devices, the resulting anastomosis is substantially round. As such, round anastomoses can be formed having increased diameters merely by increasing the lengths of the devices, obviating the need for wider endoscopes.

Methods and devices for performing gastroplasty

A gastroplasty method involves a staple line that terminates prior to reaching the gastroesophageal junction such that the bypassed portion of the stomach does not require resection. Additionally, bougies are taught that assist a physician in following the improved staple line of the present invention.
