摘要： An apparatus is for positioning an endovascular implant, such as a stent to assist in maintaining vessel patency, adjacent a junction at a branch from a vessel. A sheath includes a first lumen and a second lumen. The first lumen is adapted for receiving a catheter including the endovascular implant for positioning within the branch. An at least partially radiopaque wire is located in the second lumen. The at least partially radiopaque wire includes a pre-shaped portion, such as a bend, for locating at the junction for use in guiding the stent into position within the branch. Related methods are also disclosed.

摘要： A multipurpose handle incorporated into a medical device delivery system. The multipurpose handle includes an elongate handle body, an actuation button, and a locking member. The elongate handle body has a proximal end extending to a distal end, which defines a longitudinal axis. The elongate body further includes a cutout that creates a movement space therein in which the actuation button is disposed and is connected to a medical device. The actuation button is movable within the cutout along the longitudinal axis and rotatable within the cutout. The locking member is connected to the elongate handle body and movable between a locked position and unlocked position. The locking member may be in contact with the actuation button and be configured to restrict the movement of the actuation button along the longitudinal axis when in the locked position.

摘要： A hand-held device is used to deliver and hydrate a temporary polymeric implant having a length, an outer surface and a cross-section, with a disruptable cover over the implant. A lumen may pass through the entire length, the lumen having a surface forming an equivalent diameter in the polymeric stent. The temporary polymeric implant includes a first aqueous-swellable, biocompatible and biodegradable composition (e.g., polymer) having a thickness. The aqueous-swellable and biodegradable polymer retaining structural integrity for at least 1 hours up to thirty days when swollen and kept moist by a moist aqueous environment. Barrier layers of biodegradable polymer(s) may be used to prevent migration of liquids into the lumen.

摘要： A design capable of both mechanical thrombectomy and stenting for treating occlusions in the cerebral vasculature provides for a three-catheter setup. The first outer catheter has the largest diameter and can serve as a guide catheter while also being a sheath for the other catheters. The second deployment catheter can be configured for the aspiration of occlusions and can include a stepped or recessed section proximal of the distal tip that can act as a housing for a braided expandable stent. The outer diameter of this stepped section can be lined with an inflation device on top of which the braided stent sits. Internal to the second deployment catheter is a microcatheter which can deliver mechanical thrombectomy devices to the target site to retrieve an occlusion in the vessel, after which the stent can be expanded and implanted in the vessel.

摘要： A stent device including a stent cover having differing porosity ratio is disclosed. The stent covers the stent body comprising of stent wires and stent cells enclosed by the stent wires. The stent cover differs in porosity ratio for areas covering the stent wires and the areas covering the stent cells. The porosity ratio for areas covering the stent wires may have a higher porosity rate in order to promote endothelialization of the stent device. A bilayer stent cover differing in porosity ratio may be used to cover the stent body, as well as stent cover not covering the entirety of the stent body.

摘要： The present disclosure describes methods of making a sleeve comprising a conical frustum having first and second end profiles and a lumen there through for covering and constraining an expandable device, and apparatuses, systems, and assemblies comprising an expandable device and a sleeve having a frustoconical shape when the expandable device is at least partially expanded. The present disclosure further describes methods for deploying an expandable device in a patient comprising releasing a releasable seam disposed on a sleeve and everting the sleeve while retracting it from the expandable device.

摘要： An implantable medical device deployment system is disclosed that employs both a sheath element and a constraint member to protect implantable medical devices during delivery in a body while providing simple, accurate, and reliable device deployment. The delivery system is configured so that loading and deployment forces are not directly related to device diameter, length, or design, thus allowing a more universal delivery system across various delivered device configurations and product lines. The deployment system can provide numerous benefits, include better protection for drug-coated implantable devices.

摘要： An endoprosthesis constraining sleeve includes a single sheet of material forming at least two folds, and a common bond line constraining the single sheet of material to maintain the at least two folds and to form at least two discrete lumens. A first lumen of the at least two lumens is configured to receive a constrained endoprosthesis therein. A second lumen of the at least two lumens is configured to receive a control feature therethrough.
