A vessel occluder used to occlude blood flow within the vasculature is described. The vessel occluder can include an expandable mesh portion having a flexible membrane that expands within a cavity of the expandable mesh portion. When expanded, the flexible membrane blocks blood passage through the mesh portion.

A bleeding control device for mitigating bleeding includes a housing, inflation means, an inflatable balloon and a gas supply line. The bleeding control device may be used to deliver variable contents to a wound at the site of injury to control the bleeding of a victim as temporary solution for mitigating the bleeding until more advanced medical care can be provided. A bleeding control device includes a canister housing, a compressed gas canister arranged within the canister housing, a tube connected to the canister housing, an inflatable balloon disposed on the tube, the inflatable balloon being fluidly connected to the compressed gas canister, and a control element configured to activate the compressed gas canister to inflate the inflatable balloon.

A medical device for treating a PFO is presented as well as a mechanism for its delivery, repositioning and/or removal. The device includes a wire or cable framework of six shape-memory cables formed into a right side having six loops that support a right side sail and a left side having six loops that support a left side sail. The right side loops and left side loops are connected together via waist members that extend between the right side and left side loops. Each cable is threaded through a through hole of a central post and pass through one of each of four types of connecting collars that establish the basic shape of the PFO device and retain the cables together to form a flexible and resilient PFO device.

Devices are provided with an internal dimension that can be reduced and increased in vivo. In one example, an interatrial shunt for placement at an atrial septum of a patient’s heart includes a body. The body includes first and second regions coupled in fluid communication by a neck region. The body includes a shape-memory material. The body defines a passageway through the neck region for blood to flow between a first atrium and a second atrium. The first and second regions are superelastic at body temperature, and the neck region is malleable at body temperature. A flow area of the passageway through the neck region may be adjusted in vivo.

The device for closing openings or cavities in blood vessels, e.g. in veins or in the heart, said device comprises a closing body comprising an outer side having a partial region arranged for blood flow therealong at least in a part of said partial region thereof when said closing body is in its state of use for closing said opening or cavity. Furthermore, the device comprises at least one layer (16) of biostable nonwoven fiber material, which at least within a partial surface of said partial region of said outer side of the closing body is at least partially in abutment on the closing body.

A deployment instrument for deploying a closure device for sealing a percutaneous puncture in a wall of a body passageway, the deployment instrument including a carrier assembly, wherein the carrier assembly is configured to hold the closure device in a pre-deployment state, and a tensioner assembly, wherein the filament is fixedly attached to the tensioner assembly, wherein the deployment instrument is configured to increase the tension in the filament upon linear movement of the deployment instrument away from the wall of the body passageway when the closure device is anchored to the wall via the anchor such that the tension is gradually increased as the deployment instrument is moved between a first linear distance and a second linear distance greater than the first linear distance from the wall of the body passageway.

Wound closure devices, systems, and methods may be used to close an opening, such as a puncture wound or incision, formed in tissue, such as heart tissue. A wound closure device may be configured and adapted to be placed within the puncture wound or incision to close and/or seal the puncture wound or incision. A bioadhesive may be used to strengthen the closure and/or seal of the puncture wound after placement of the wound closure device relative to the puncture wound.

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.

There are shown and described embodiments of a closure device for closing holes in tissue, for example in the right atrial appendage. The closure device in particular embodiments includes first and second mesh closure members and a tether or stem connecting them. Embodiments of a delivery device for the closure device are also described.

The double “J” laparoscopic fascial closure device has a fixed jaw and a movable jaw pivotally attached to the fixed jaw. An elongated hollow tube or cannula extends from the fixed jaw. The end of the elongated cannula distal from the jaws has two needles mounted thereon defining a double “J” configuration. A spring mechanism or cable guide is attached to the hollow tube, and a cable extends between the fixed jaw and the movable jaw. The other end of the cable extends through the elongated hollow tube, through the spacer arms, and back towards the needles at the ends of the needle mount arms. A suture thread is attached to both needles so that the thread bridges the gap between fascia on opposite sides of the laparoscopic port incision when the needles are draw back through the fascia towards the incision.
