Scaffolds for implanting absorbable hemostats in field conditions
The present invention relates generally to agents and devices for promoting hemostasis and, more particularly, to bioresorbable hemostatic pads or patches releasably supported on non-resorbable scaffolds for ease of delivery in the field. A sealant and/or hemostat delivery device comprises a resorbable hemostatic pad having a wound facing side and an opposite back side, with a hemostatic and/or wound sealing agent disposed on the wound facing side; a non-resorbable scaffold having an attachment zone on said scaffold; wherein said hemostatic pad is releasably attached with the back side to the attachment zone. The bond between the scaffold and the resorbable hemostatic pad or wound dressing is either (i) severed prior to removal of the scaffold or (ii) is weakened due to the adhesive bonding them together being moisture-deactivated, or (iii) is released by mechanical disentanglement.
Vessel sealing device
A seal assembly that seals opening in the wall of a blood vessel has a first sealing element for placing inside the lumen of the blood vessel and to engage the interior wall surface, a shaft integrally formed with the first sealing element and fixed in a predetermined configuration relative to the first sealing element, an outer floating element slidingly movable along the shaft; and a second sealing element, the second sealing element slidingly movable relative to the first sealing element along the shaft to engage the outer floating element and position the outer floating element against the exterior surface and the first sealing element against the interior surface of the blood vessel to seal the opening in the blood vessel.
Vascular hole closure device
A device for closing an aperture in a vessel wall, the aperture having an external opening in an external region of the vessel wall and an internal opening in an internal region of the vessel wall. The device includes a covering member positionable inside the vessel against the internal opening of the aperture and having a dimension to prevent egress of fluid through the aperture. A securing member is positionable external of the vessel and has a plurality of pores extending therethrough. A flexible connecting member operatively connects the covering member and securing member and moves the securing member toward the covering member.
MEDICAL PLUG DELIVERY DEVICES WITH A ROTATABLE MAGAZINE AND RELATED COMPONENTS AND METHODS
Medical devices for delivering compositions or medical articles to a patient are disclosed. The medical plug delivery devices can include a fluid delivery device (e.g., a syringe), a frame, and a rotatable magazine. The rotatable magazine can include a plurality of chambers that each hold a composition or a medical article (e.g., a medical plug). By rotating the rotatable magazine relative to the frame, material within the chambers of the rotatable magazine can be sequentially deployed to a patient.
System and method for vessel access closure
Embodiments are described for closing vascular access ports, such as arteriotomies, which involve placement and deployment of an expandable device configured to prevent blood flow across a subject arteriotomy while also keeping disturbance of intravascular flow to a minimum. Suitable prostheses may comprise one or more frames constructed from lengths of flexible materials, such as shape memory alloys or polymers. Such frames may be coupled to sheetlike or tube-like structures configured to spread loads, minimize thrombosis which may be related to intravascular flow, and maintain hemostasis.
ADJUSTABLE VASCULAR CLOSURE DEVICE
The disclosed technology provides a device (10) for sealing an aperture in a tissue of a body lumen. The device includes a flexible support member (14) having a base (19) configured to engage and/or hold a sealable member (12) of the device against an interior surface of the tissue when the device is in the sealing position. The device also includes a locator (16) coupled to the support member and configured to engage with a wall of the body lumen to secure the device thereto.
Sutureless Repair of Soft Tissue
The present invention relates to a sutureless method of repairing soft tissue defects in soft tissue including ligaments such as anterior cruciate ligaments (ACLs). In particular, the present invention relates a sutureless method of repairing soft tissue defect comprising: (i) providing a collagen-containing patch adapted to enclose at least a portion of said soft tissue defect; (ii) contacting said soft tissue defect and/or collagen-containing patch with a sensitizer; (Hi) enclosing said soft tissue defect in said collagen-containing patch to produce a bioactive chamber; and (iv) adhering said collagen-containing patch to said soft tissue defect without sutures.
Surgical fastener applying apparatus
A surgical fastener applying apparatus includes an anvil half-section and a cartridge-receiving half-section including an elongated channel member having a pair of opposed openings defined through sidewalls thereof. A disposable assembly including a single use loading unit and a single use firing unit is configured to be releasably supported within the cartridge-receiving half-section. The disposable assembly includes a stationary housing for supporting the firing unit which includes a distal extension for supporting the single use loading unit. The stationary housing includes a pair of flared tabs configured to be releasably received within the openings of the cartridge-receiving half-section to releasably engage the disposable assembly within the cartridge-receiving half-section.
Mesh implant for use in reconstruction of soft tissue defects
The present invention relates to a resorbable polymeric mesh implant, that is intended to be used in the reconstruction of soft tissue defects. The mesh implant has at least a first and a second material, wherein the second material is substantially degraded at a later point in time than the first material following the time of implantation. The mesh implant is adapted to have a predetermined modulus of elasticity that gradually is decreased until the mesh implant is completely degraded and subsequently resorbed. Due to the gradual decrease in the modulus of elasticity of the inventive mesh implant, the regenerating tissue may gradually take over the load applied to the tissue defect area. Interstices between individual filaments of multifilaments create a capillary effect for cells within the body.
MEDICAL DELIVERY DEVICE AND METHODS OF USING THE SAME
A medical device comprising a first tube, a second tube configured to sheath at least a portion of the first tube and configured to translate along a length of the first tube, an expandable device at a distal portion of the first tube, the expandable device having a collapsed state and an expanded state, a patch surrounding at least a portion of an outer surface of the expandable device, and a connector for holding the patch to the expandable device when the second tube covers the patch and the expandable device and for releasing the patch from the expandable device after the second tube uncovers the patch and the expandable device.
