International Classification:

A61B 17/10
A61B 17/08

US Classification:

606139, 606151

Abstract:

The invention relates to devices, systems, and methods for percutaneously suturing biological material, such as a patient's tissues. In one embodiment, a suturing device includes first and second tissue engaging members connected to one another by a first interconnecting member. In another embodiment, systems and methods are provided for forming holes through two overlapping layers of tissue. Subsequent to forming holes through the two layers of tissue, the suturing device is positioned through the holes to join or bring into contact the two layers of overlapping tissue.

International Classification:

A61N 1/00

US Classification:

607116, 606 41

Abstract:

The present invention provides systems and methods for occluding or closing a patent foramen ovale of a patient (PFO). The invention includes a catheter carrying an energy delivery element. The catheter introduces the energy delivery element into the patent foramen ovale of a patient's heart. Once appropriately positioned, the energy delivery element applies energy, such as radiofrequency energy, to the tissues surrounding the patent foramen ovale. The application of energy causes the tissues to join together, occluding the patent foramen ovale. The energy delivery element may be removable or permanently implanted in the patent foramen ovale.

International Classification:

A61B 17/08

US Classification:

606213

Abstract:

An implant for occluding a septal defect, such as a patent foramen ovale (PFO), and methods of delivering the implant are described. The implant includes a scaffold, at least one channel, and an injection port in fluid communication with the channels for inflating the scaffold.

Assignee:

NMT Medical, Inc. - Boston MA

International Classification:

A61B 17/08

US Classification:

606157, 606213

Abstract:

A delivery/recovery system to allow an operator to deploy and recover a medical implant, such as an occluder for closing a patent foramen ovale (PFO). In one embodiment, the system includes a delivery mandrel for preventing the occluder from moving in the proximal direction, a delivery wire for securing the occluder to the delivery mandrel and preventing unwanted movement in the distal direction, and a sheath for enveloping the delivery wire, mandrel and occluder. By moving the sheath relative to the occluder in a series of steps, the occluder opens first on a distal side and then on a proximal side, in a manner that holds the occluder in place.

International Classification:

A61B 18/14

US Classification:

606 49, 606 41, 606 47

Abstract:

A welding element is provided for applying heat, chemicals, pressure, or any combination thereof to tissues inside a patient's body, e. g. , a patent foramen ovale. In one aspect, the welding element is connected to a radio frequency energy source and includes an electrode and a locator. The locator facilitates positioning of the welding element and is capable of moving from an open position to a clamping position. In another aspect, a needle is provided for transseptal puncturing before the application of heat. In yet another aspect, the welding element is configured as a coil. The welding element can be made of Nitinol.

Appl. No.:

10/911980

Inventors:

Carol A. Devellian - Topsfield MA, US

Assignee:

W.L. Gore & Associates, Inc. - Flagstaff AZ

International Classification:

A61M 29/00

US Classification:

606200, 623 111, 606213

Abstract:

The embodiments of the present invention provide a device that modifies the left atrial appendage (LAA) to reduce the likelihood of thrombus formation therein. The device includes a liner that reduces the volume of the LAA and remodels the interior geometry and surfaces of the LAA thereby minimizing the crenellations in the LAA that impede blood flow. According to some embodiments, the device further includes an anchor component. The anchor component helps to expand the liner upon deployment of the device in-vivo and further prevents dislodgement and migration of the device, by ensuring the device is properly seated and completely sealed against the walls and ostium of the LAA.
