  • Patent number: 8137364
    Abstract: Devices, systems, and methods for suturing of body lumens allow the suturing of vascular puncture sites located at the distal end of a percutaneous tissue tract. An elongated articulated foot near a distal end of a shaft is inserted through the penetration and actuated so that the foot extends along the lumenal axis. The foot carries suturing attachment cuffs, and needles are advanced from the shaft through the vessel wall outside of the penetration and into engagement with the needle cuffs after the foot has been drawn proximally up against the endothelial surface of the blood vessel. The cross-section of the shaft within the tissue tract can be minimized by laterally deflecting the needles as they leave the shaft, while tapered depressions within the foot can guide the advancing needles into engagement with the cuffs. The cuffs lockingly engage the needles and can be withdrawn proximally along the needle paths and through the tissue tract so as to form a loop of suture across the puncture.

  • Patent number: 7699856
    Abstract: A novel suture removal instrument, kit and technique are described herein. The invention utilizes a newly designed thermal filament to allow the tip of the suture removal instrument to be slipped under the stitch in order to heat and cut the stitch. Current suture removal techniques utilize scissors, forceps, and/or scalpels. These techniques, which are well known in the art, are problematic because they exert tension on the stitch and are associated with patient discomfort. Small stitches add to the difficulty of suture removal because they have less suture laxity for scissor insertion. The present invention therefore allows for more rapid suture removal with less patient discomfort and at a competitive or lower cost.

  • Patent number: 7131977
    Abstract: An endoscopic apparatus includes a pair of jaws pivotably connected to each other and movable between an open position and a closed position. The jaws have respective opposing gripper portions. Each gripper portion has a distal end, a proximal end, and an inside surface extending between the distal and proximal ends. At the closed position, the inside surfaces define a jaw gap therebetween. At least a portion of the jaw gap increases in distance along a direction from the distal end toward the proximal end. An actuating mechanism communicates with the jaws for moving the jaws between the open and closed position. In a surgical procedure in which a clip such as a hemostatic clip has been latched around a blood vessel or other tissue, the apparatus can be used to compress the clip and consequently unlatch the clip, thereby releasing the clip from the vessel. Thereafter, the apparatus can be rotated.

  • Patent number: 7048746
    Abstract: Novel suture removal instrument and technique are described herein. The invention utilizes a newly designed thermal filament to allow the tip of the suture removal instrument to be slipped under the stitch in order to heat and cut the stitch. Current suture removal techniques utilize scissors, forceps, and/or scalpels. These techniques, which are well known in the art, are problematic because they exert tension on the stitch and are associated with patient discomfort. Small stitches add to the difficulty of suture removal because they have less suture laxity for scissor insertion. The present invention therefore allows for more rapid suture removal with less patient discomfort and at a competitive or lower cost.

  • Publication number: 20030167062
    Abstract: Suture clips and suture clip loading, delivery, locking and severing devices in both catheter and endoscopic embodiments are disclosed that permit the delivery and application of suture clips directly in contact with or in close approximation to sutured tissue. The catheter or endoscopic versions incorporate a collet cage with a plurality of flexible collet fingers that captivate a suture clip ring and a suture clip plug for assembly with a suture. An outer sliding sleeve constrains the collet fingers when distally advanced to minimize potential trauma during delivery and assembly of the suture clip in close proximity to the stitched tissue. Proximal retraction of the sliding sleeve coupled with the distal advancement of a pusher against cam surfaces on the inner walls of the collet fingers causes the collet fingers to open. The catheter is designed to hold and assemble the suture clip in a first position and release the suture clip and sever the suture ends proximal to the suture clip in a second position.

  • Publication number: 20020029048
    Abstract: A endovascular fastener and grafting apparatus preferably made from a shape memory alloy is provided which can access internal tissue or other synthetic material by catheter delivery through an endovascular pathway. After the fastener is deployed through layers of tissue or other material, it assumes a shape that automatically applies to the layers of tissue or other material an appropriate hemostatic compression which is relatively independent of tissue or material thickness. The fastener is a suitable replacement for conventional nonbio-absorbable sutures and staples in certain clinical applications. The shape, method of deployment and low force requirements make the disclosed apparatus suitable for standard endovascular surgical procedures where access to the deployment site is limited. A method for deploying the endovascular fastener and grafting apparatus is also provided.

  • Patent number: 6126651
    Abstract: An apparatus for open-heart surgery includes a suture-needle holding tip (10) or a stapler and a handle (100). The tip is driven to oscillate relative to the handle in the same motion as the surface of the heart, which is being operated on. This cancels the motion of the heart, effectively stopping it, so that the surgeon (S) need not compensate for heart beats. The tip can grasp or release the needle (N) with a mechanism (300) under control of a switch (330) through a flexible cable 120. Independently, a drive mechanism 200 causes a cam (230) to be turned by a motor 213 for driving the needle-holding tip by means of a flexible cable 120. The cam is shaped so that the pattern of the platform oscillation follows the beating heart's motion. A momentary-contact switch triggers a pacer, which paces the heart to beat in synchrony with the motion of the needle-holding tip. The rate is set slightly above the un-paced heart beat rate.
