Adhesive pad and hemostasis system
An adhesive pad for use with a hemostasis device comprising a footplate having a top surface and a receiving device positioned on the footplate, the adhesive pad comprising: (1) a flexible backing layer having a bottom surface, a central portion having an opening, a first side portion, and a second side portion; (2) an adhesive layer applied to the bottom surface of the backing layer; and (3) a release layer removably secured to the adhesive layer. The opening in the central portion of the backing layer is sized to fit the receiving device of the hemostasis device, and the adhesive layer applied to the bottom surface of the first and second side portions of the backing layer is configured to adhere to and extend beyond the top surface of the footplate.
System for Use in Sealing a Portion of Pleural Layers Together
A system for use in sealing a portion of pleural layers together includes an electrical energy source, and an electrocautery probe electrically coupled to the electrical energy source. The electrocautery probe has a cannula shaft portion, a distal penetrating tip, and an intermediate portion interposed between the cannula shaft portion and distal penetrating tip. The electrocautery probe is configured to generate heat. A protein source is coupled to the intermediate portion of the electrocautery probe, wherein the protein source has a protein that is denatured by heat.
CLOSURE DEVICES AND METHODS FOR SEALING BIOLOGIC TISSUE MEMBRANES
An implantable closure device for sealing an opening, such as a puncture, through a biologic tissue membrane, such as the meninges, against leakage of biological fluid. The closure device includes a fluid sealing plug configured to be positioned at least partially within the opening through the biologic tissue membrane. A retainer is configured to secure the fluid sealing plug at least partially within the opening. The retainer includes a proximal retainer portion configured to be disposed proximally on the biologic tissue membrane, a distal retainer portion configured to be disposed distally on the biologic tissue membrane, and a central retainer portion connecting the proximal retainer portion and the distal retainer portion. The central retainer portion is configured to extend through the opening. The fluid sealing plug is coupled to the central retainer portion.
Braided medical device and manufacturing method thereof
An medical implantable occlusion device (100) is disclosed having a collapsed state and an expanded state and comprising a braiding (101) of at least one thread, and a distal end (102) comprised of said braiding. The distal end comprises loops (103, 104, 204, 304) formed by loop strands (105, 106, 206, 306) of the at least one thread, wherein, at least in said expanded state, each loop strand has a curved shape and extends away from a centre point (117) of the distal end, whereby an apex point (107, 108, 208, 308) of each of the loop strands corresponds to the turning point of the curved shape and to the point of each of the loop strands being arranged closest to the centre point. At least one of the loop strands is displaced from the centre point by a centre distance (109, 110, 210, 310), and the apex point lie at a distance from a periphery (113) of the distal end.
Introducer sheath
An introducer sheath is disclosed configured to be percutaneously inserted into a biological lumen and can shorten the time required for hemostasis at a wound site and lessen the physical burden on the patient after withdrawal of the introducer sheath. The introducer sheath includes a catheter body to be percutaneously introduced into a biological lumen, a hub configured to be connected to the proximal side of the catheter body, and a drug part that has a hemostatic agent capable of treating a wound site in biological tissue. The drug part is disposed at the proximal side of an outer surface of the catheter body.
VASCULAR CLOSURE DEVICES AND METHODS PROVIDING HEMOSTATIC ENHANCEMENT
Vascular closure devices and methods for closing a blood vessel puncture site disposed at a distal end of a tissue tract are described. A combination of the body's own natural mechanism with chemical and/or biological agents is relied upon to accelerate the hemostatic process. Included are steps of introducing a closure device through the tissue tract and deploying an expansible member at a distal end of the device within the blood vessel to occlude the puncture site. A sealing member disposed proximal the expansible member is then displaced by retracting and tensioning a coil spring so as to expose a chemical and/or biological region or release region of the device. The retraction and tensioning of the coil spring is limited by a coupling member. Exposure of blood and tissue to the chemical and/or biological sealing member promotes the clotting processing to accelerate the occlusion process in the tract.
Clip applier and methods of use
A system having an elongate assembly, an expandable assembly having a fixed end region and a movable end region, the expandable assembly selectively transitioning between an expanded state and an unexpanded state with movement of the movable end region towards the fixed end region, and an advancement aid extending distally from the expandable assembly.
Apparatus and methods to create and maintain an intra-atrial pressure relief opening
The present disclosure relates to a method and a device for treating heart failure by normalizing elevated blood pressure in the left and right atria of a heart of a mammal. The present disclosure includes methods for creating and maintaining an opening in the atrial septum. Tools for making an opening and enlarging the opening are also disclosed. Use of the techniques and tools described herein prolongs the patency of an intra-atrial pressure relief opening.
Instrument and methods for surgically closing percutaneous punctures
A closure device for sealing a percutaneous puncture in a wall of a body passageway, the closure device including at least one of a toggle configured to engage an interior surface of the body passageway or a plug configured to engage an exterior surface of the body passageway and a guide wire configured to extend from an outside of the body to inside the body passageway, wherein at least one of the toggle and the plug is associated with the guide wire.
Apparatus and methods for transfemoral delivery of prosthetic mitral valve
Apparatus and methods are described herein for use in the transfemoral delivery and deployment of a prosthetic mitral valve. In some embodiments, a method includes inverting an outer frame of a prosthetic mitral valve when in a biased expanded configuration. After inverting the outer frame, the prosthetic mitral valve is inserted into a lumen of a delivery sheath such that the mitral valve is moved to a collapsed configuration. The delivery sheath is inserted into a femoral vein and moved through the femoral vein and a septum of a heart until a distal end of the delivery sheath is disposed in the left atrium of the heart. The prosthetic mitral valve is moved distally out of the delivery sheath such that the inverted outer frame reverts and the prosthetic mitral valve assumes its biased expanded configuration. The prosthetic mitral valve is then positioned within a mitral annulus of the heart.
