A composite implant is provided for repairing a tissue defect in a patient. In one embodiment, the implant is a porous tissue scaffold having at least one pocket formed therein and adapted to contain a viable tissue. The tissue scaffold can have a variety of configurations, and in one embodiment it includes top and bottom portions that can be at least partially mated to one another, and in an exemplary embodiment that are heated sealed to one another around a perimeter thereof to form an enclosed pocket therebetween. The pocket is preferably sealed with a viable tissue disposed therein. In another embodiment, the tissue scaffold is substantially wedge-shaped and the pocket comprises a hollow interior formed in the tissue scaffold, and/or at least one lumen extending into the tissue scaffold. The tissue scaffold can also optionally include at least one surface feature formed thereof to promote blood vessel formation.

Devices and techniques for modifying and maintaining a configuration of an occlusion device for the closure of physical anomalies, such as an atrial septal defect, a patent foramen ovale (PFO), and other septal and vascular defects are described. The devices and techniques relate particularly to, but are not limited to, modifying and maintaining a configuration of a PFO occluder made from a polymer tube. The proximal portion of a catch member may be provided with one or more protrusions, or arms, or bump or other raised element for securing the occluder in a partial or fully deployed configuration, either temporarily or permanently.

Catch members for occluder devices

Devices, delivery systems and delivery techniques for an occlusion device for the closure of physical anomalies, such as an atrial septal defect, a patent foramen ovale (PFO), and other septal and vascular defects are described. The devices, delivery systems and delivery techniques relate particularly to, but are not limited to, a patent foramen ovale (PFO) occluder made from a polymer tube. In certain embodiments, the occluder includes a catch system that holds the occluder in the deployed, expanded profile. The catch system includes a locking funnel cap. In some embodiments, the locking funnel cap forces the proximal ends of the occluder in a radially inward position to lock the catch member in place and prevent the occluder from moving from its deployed configuration.

Methods and apparatus for treating meniscal tissue damage are disclosed, including a biocompatible meniscal repair device comprising a biocompatible tissue repair scaffold and a cell growth conduit flap. The tissue repair scaffold is adapted to be placed in contact with a defect in the meniscus and can preferably provide a structure for supporting meniscal tissue and/or encouraging tissue growth. The cell growth conduit flap, which is attached to the tissue repair scaffold, allows communication between the synovium and the tissue repair scaffold.

Meniscal repair scaffold

The invention provides a cardiovascular occluder for treating a cardiovascular abnormality comprising a frame and an alarmin or an alarmin activator bound to the surface of the frame. The invention further provides methods of manufacturing the cardiovascular occluder and methods of treating cardiovascular abnormalities by delivering the cardiovascular occluder.

Intracardiac implant for delivery of alarmins and methods thereof

Biocompatible tissue implants are provided for repairing a tissue injury or defect. The tissue implants comprise a biological tissue slice that serves as a source of viable cells capable of tissue regeneration and/or repair. The biological tissue slice can be harvested from healthy tissue to have a geometry that is suitable for implantation at the site of the injury or defect. The harvested tissue slice is dimensioned to allow the viable cells contained within the tissue slice to migrate out and proliferate and integrate with tissue surrounding the injury or defect site. Methods for repairing a tissue injury or defect using the tissue implants are also provided.

Viable tissue repair implants and methods of use

Devices, delivery systems and delivery techniques for an occlusion device for the closure of physical anomalies, such as an atrial septal defect, a patent foramen ovale (PFO), and other septal and vascular defects are described. The devices, delivery systems and delivery techniques relate particularly to, but are not limited to, a patent foramen ovale (PFO) occluder made from a polymer tube, specifically, a petal-shaped occluder. In certain embodiments, the catch system includes a catch member with a screw catch mechanism for connecting to the occluder. A delivery system for use with the catch member includes a component for rotating the catch member relative to the occluder to engage the screw catch mechanism.

Screw catch mechanism for PFO occluder and method of use

A biocompatible meniscal repair device is disclosed. The tissue repair device includes a scaffold adapted to be placed in contact with a defect in a meniscus, the scaffold comprising a high-density, dry laid nonwoven polymeric material and a biocompatible foam. The scaffold provides increased suture pull-out strength.

Nonwoven tissue scaffold

This invention relates to a syringe-activated valve for flushing a catheter for delivering an implant to an anatomical site, such as a patent foramen ovale in a patient and method thereof. In one embodiment, a catheter includes a proximal end, a distal end, a 'Y' connector at the proximal end, the 'Y' connector having a guide wire port and a connector port, a syringe activated valve having a first end and a second end, the second end of syringe-activated valve connecting to the connector port of the &#x201c;Y&#x201d; connector, and a syringe connecting to the first end of the syringe-activated valve. Saline is injected by the syringe through the syringe-activated valve into the proximal end of the catheter, thereby flushing air from the catheter lumen out of the distal end of the catheter.
