A hemostatic device includes a first tube defining a first lumen configured to channel a fluid therethrough, and a second tube housing at least a portion of the first tube and at least partially defining a second lumen configured to retain a hemocoagulant agent therein. The second tube is moveable with respect to the first tube, such that the hemocoagulant agent is at least substantially retained within the second lumen when the second tube is in a first position, and the hemocoagulant agent is at least partially exposed when the second tube is in a second position.

A hemostatic device for sealing a puncture of a vessel includes a first tube defining a first lumen. The first lumen is configured to receive a guidewire and a flow of a fluid therethrough. The hemostatic device also includes a second tube circumscribing at least a portion of the first tube and at least partially defining a second lumen. The hemostatic device further includes a substantially rigid stopper coupled to a distal end of the second tube. The stopper defines a stopper lumen that receives the first tube therethrough in an interference fit. A first opening is defined in a side wall of the first tube and positioned distally relative to the stopper. At least one injection groove defined in an outer surface of the stopper cooperates with the distal end of the second tube to define at least one second opening in flow communication with the second lumen.

Multiple endoscopic devices and methods for closing perforations and/or creating anastomoses in tissue are described. For example, this document provides devices and methods for performing esophagogastric anastomoses and for closing esophageal perforations in a minimally invasive fashion. The devices and methods provided herein can also be used for, without limitation, colorectal anastomoses, any bowel anastomosis, gastric bypass anastomoses, and broader vessel anastomoses.

Disclosed are puncture sealing systems and methods of locating a puncture site within a vessel. The systems can include elongated dilators and access sheaths that are configured to locate the puncture site within a vessel so that the position of the puncture site relative to a distal end of the access sheath is known during a puncture sealing procedure.

A hemostatic device for sealing a puncture of a vessel includes a first tube defining a first lumen, and a malecot coupled to the first tube. The malecot is selectively actuatable from a neutral configuration to a stopper configuration. The hemostatic device also includes a second tube circumscribing at least a portion of the first tube. The second tube at least partially defines a second lumen and a third lumen. The second tube includes a first opening in flow communication with the third lumen and positioned proximally relative to the malecot. The second tube is selectively orientable to at least partially expose a hemocoagulant agent retained in the second lumen.

The present invention relates to a vascular closure device for sealing a puncture site in a vascular wall comprising a sheath (10) having a distal end and at least one proximal end, wherein the sheath (10) comprises a tubular body (100). The vascular closure device (1) is characterized in that at least one distal balloon member (11) is firmly arranged at the distal end of the tubular body (100) of the sheath (10) and at least one expandable anchor member (12) is firmly arranged proximal to the distal balloon member (11) on the tubular body of the sheath (10), wherein at least the distal side of the distal balloon member (11) is a pressure area for applying pressure on the outside of the vascular wall. Furthermore a method of positioning of a vascular closure device (1) is described.

A closure system configured to facilitate hemostasis at a puncture of a vessel includes a delivery sheath that extends longitudinally from a proximal end to a distal end. The delivery sheath defines a lumen extending therethrough. The delivery sheath lumen is configured to receive a first guidewire therethrough. The system also includes an introducer needle coupled to the delivery sheath at an offset relative to the delivery sheath. The introducer needle defines a lumen extending therethrough. The introducer needle lumen is configured to receive a second guidewire therethrough.

Systems, devices, and methods for providing access to the heart. The system includes an intracardiac access device comprising an elongate member having a channel extending between a distal end and a proximal end thereof. The intracardiac access device is configured to be advanced through an extrapericardial penetration in the left atrial wall without penetrating the pericardium of the heart. An optional procedural device is configured to be advanced through the channel of the intracardiac access device into an internal chamber of the heart and configured to perform a surgical procedure in the internal chamber of the heart. A working channel of an optional suprasternal access device is configured to facilitate access of the intracardiac access device into the body of the patient by providing a path from a suprasternal opening to a position adjacent the roof of the left atrium.

A surgical instrument and method for indicating a tissue penetration site includes an inner needle and a head. The inner needle has a driver configured to translate the inner needle form a first position to a second position. The head is securely attached to the inner needle at an end opposite the driver and is configured to expand from a contracted state to an expanded state and thereby indicate the tissue penetration site.

An expandable screw includes generally a shaft, a head, and a cut pattern. The shaft includes a longitudinal axis, an outer surface including a thread to engage bone, and an expandable region configurable between a first state with a first radius measured from the longitudinal axis to the outer surface and a second state having a second radius measured from the longitudinal axis to the outer surface. The cut pattern on the shaft permits at least partial nesting of a first portion of the expandable region within a second portion of the expandable region in the second state. The central lumen is closed by the abutment of a top portion of the second cut surface with the bottom portion of the first cut surface so as to form a closed structure or fluid seal preventing a bone ingrowth inside the central lumen.
