Systems and methods can remove material of interest, including blood clots, from a body region, including but not limited to the circulatory system for the treatment of pulmonary embolism (PE), deep vein thrombosis (DVT), cerebrovascular embolism, and other vascular occlusions.
摘要:
A device for occluding a vasculature of a patient including a micrograft having an absorbent polymeric structure with a lumen of transporting blood. The micrograft has a series of peaks and valleys formed by crimping. The occluding device is sufficiently small and flexible to be tracked on a guidewire and/or pushed through a microcatheter to a site within the vasculature of the patient. Delivery systems for delivering the micrografts are also disclosed.

Implantable materials for use with end effectors like surgical stapling devices, and methods for using the same, are generally provided. In some embodiments, adjunct materials for use with surgical staplers are provided. For example, a kit for stapling tissue is provided that can include a surgical stapler having an end effector. The end effector can have first and second jaws. The kit can include an adjunct material having hydrophobic surface regions and hydrophilic surface regions and the adjunct material can be configured to mate to at least one of the jaws of the end effector. Other implants, devices, and methods for surgical stapling are also provided.
摘要:
A marker device that aids in the subsequent identification of a particular area is equipped with an anchoring device that prevents migration once placed in the tissue of that particular area. The device may include a chemical agent or drug that adds a therapeutic function to the marker device.
摘要:
A device including a tissue manipulator, a conductive coating and at least one connector area. For example, the tissue manipulator may be scissors, clip appliers or clips, staplers and staple or a vessel sealing device. The conductive coating may be applied to the clip, staple or jaws of the scissors or sealing device. Electrical energy can be supplied through areas of contact (connector areas)—such as between an anvil and a pusher of the stapler and the conductive coating on the staple. The conductive coating can be energized along with mechanical application of the manipulator to transform and facilitate attachment of tissue layers.

A percuscopic access device is disclosed. The percuscopic access device has a hollow shaft with a proximal opening and a distal opening. The percuscopic access device also has one or more barrier ridges on the outside of the hollow shaft. The percuscopic access device also has one or more recesses on the inside of the hollow shaft and in communication with the distal opening. A cleaning obturator for use with the percuscopic access device is also disclosed. The cleaning obturator and percuscopic access device may be combined as a surgical apparatus. The cleaning obturator has a guide rod having a proximal end and a distal end. The cleaning obturator also has a plugging tip on the distal end. The cleaning obturator further has one or more swab guides proximal to the plugging tip.
摘要:
Described herein are compositions comprising, a polymer; a non-physiological solution; and a visualization agent; wherein the polymer is soluble in the non-physiological solution and insoluble at physiological conditions. Methods of preparing the compositions are disclosed as well as methods of using these compositions to treat vascular conditions.
摘要:
A thrombectomy device including a delivery catheter; a tapered dilator catheter configured to be movably disposed within the delivery catheter; and an expandable aspiration funnel configured to be movably disposed within the delivery catheter in a retracted position and at least partially outside the delivery catheter in an extended position, the funnel comprising a non-permeable covering, a diameter of a distal end of the funnel being greater in the extended position than in the retracted position, the funnel being configured to adapt its shape and length to a surrounding blood vessel such that the funnel lengthens as it narrows to retain a thrombus within the funnel. The invention also includes methods of using the device.

摘要:
The invention relates to a medical device intended to be inserted into the lumen of a cavity of the human or animal body or in the lumen of a blood vessel. The invention is characterised in that said device comprises a probe (5) suitable for delivering a treatment by the endovenous route, and, at the terminal end thereof, a hooked flexible tip (1), wherein the angle α formed between the extension of the end portion of the probe (5) and the extension of the end portion of the tip (1) is strictly less than +90°, said tip comprising means (3) for delivering a treatment. The invention is particularly applicable to the treatment of varicose veins, reticular veins and spider veins.
