| 20080268190 | DEGRADABLE, SOFT-FEEL NETTING - The present invention provides degradable extruded netting. The netting comprises a plurality of oriented interconnected strands that intersect during extrusion. At least some of the strands include a degradable composition comprising a stiffening agent, a degradable material and a crystallinity inhibiting agent. In some embodiments, the stiffening agent comprises a polylactic acid polymer, the degradable material comprises a polyester degradable plasticizer, and the crystallinity inhibiting agent comprises a starch-based polymer. In certain embodiments, the degradable composition may comprise 10 to 70 weight percent polylactic acid polymer, 15 to 75 weight percent polyester degradable plasticizer, and 5 to 30 weight percent starch-based polymer. In other embodiments, the degradable composition may further comprise a friction reducing additive. | 10-30-2008 |

| 20080269786 | Suturing Devices and Methods for Closing a Patent Foramen Ovale - Methods and apparatuses are disclosed for closing a patent foramen ovale. Some of the disclosed apparatuses include an elongate body having a proximal end and a distal end, with first and second suture clasp arms adapted to hold end portions of a suture when in an extended position. A first suture catch mechanism is slidably housed in the elongate body and moves in a proximal-to-distal direction to engage the suture end held by the first suture clasp arm, and a second suture catch mechanism is slidably housed in the elongate body and moves in a distal-to-proximal direction to suture end held by the second suture clasp arm. The first suture clasp arm can be positioned around the septum primum to deliver a suture thereto, and the second suture clasp arm can be positioned around the septum secundum to deliver a suture thereto. | 10-30-2008 |
| 20100030242 | SUTURING DEVICES AND METHODS FOR SUTURING AN ANATOMIC VALVE - A device for suturing an anatomic valve can comprise an elongate body, a suture catch mechanism and a suture clasp arm. The suture catch mechanism can be operatively coupled to the elongate body for movement between a retracted position and an advanced position. The suture clasp arm can be attached to the elongate body for movement between a retracted position and an extended position. The suture clasp arm can comprise a suture clasp configured to releasably retain a suture portion. In some embodiments, the suture clasp is positioned on the suture clasp arm such that the suture catch mechanism retrieves the suture portion from the suture clasp arm while the arm is at least partially retracted. In some embodiments, the suture clasp arm can be closed about a tissue portion without damaging the tissue portion. | 02-04-2010 |
| 20110015655 | Handle for Suturing Apparatus - Methods and apparatus are provided for closing incisions within biological tissue. In one embodiment, a device and method are provided for suturing biological tissue, such as, for example, an organ or blood vessel. The suturing apparatus is particularly well suited for suturing an incision made in an artery, such as the femoral artery, following a catheterization procedure. The device eliminates the need to apply pressure to a patient's thigh for an extended period of time, and eliminates many of the complications and costs associated with the creation of a thrombus patch. In addition, the device comprises an improved handle portion which enables the physician to quickly and easily apply suture. The handle portion is very reliable and easy to manipulate. The suturing may be used in combination with existing catheter sheath introducers. | 01-20-2011 |
| 20110190793 | METHODS AND APPARATUSES FOR SUTURING OF CARDIAC OPENINGS - A suturing apparatus configured to suture an opening extending through an outer wall of the heart, such as a transapical opening, can comprise an elongate body having a proximal end, a distal end, a tapered or rounded tip, one or more arms, and one or more needles. A handle at the proximal end of the elongate body can be configured to be manipulated from outside of the heart. The elongate body can have a substantially constant outer diameter between the handle and the distal end. The arms can hold portions of suture a distance away from the outer diameter of the elongate body. The arms can be extendable from said body from a retracted position to an extended position. The arms in the extended position can point distally and form an acute angle with a longitudinal axis of the elongate body. The plurality of needles can be movable to pass through heart tissue into engagement with the suture portions held by the arms and back through the heart tissue to draw the suture portions through the heart tissue. | 08-04-2011 |
