  • Patent number: 10743744
    Abstract: An endoscope and methods of use thereof is provided with at least one multi-functional, multi-directional arm supporting a plurality of imaging, lighting and other sensory elements. The multi-functional arms provide a mounting platform upon which cameras, lights and sensors may be mounted to generate multiple-angled images and video, arena-like lighting and other data relevant to performing a diagnostic or MIS procedure. The multi-directional arms may be inserted through a single portal in the endoscope and deployed in multiple directions from a single portal once inserted into a body cavity. The pitch, roll, length and curvature of each of the extending arms may be individually or jointly adjusted to create a customized view of an internal space during an endoscopic procedure.

  • Patent number: 10441746
    Abstract: A device, a method of making a device and a method of inserting a device into a tubular path. The device includes a tubular sheath with one or more helical slots formed therein and a control element that fits within the sheath. In one form, the device is an endoluminal device that simultaneously improves flexibility and structural rigidity though variations in one or both of slot width along the length of the slot and slot pitch along the length of the tubular sheath. When the operator pulls at the proximal end of the control element while holding the outer sheath in place, the slots will tend to close in a preferential manner such that more precise control of device length and bending is enabled, while simultaneously providing improvements in structural rigidity during device insertion and navigation through a body lumen or related tubular member where tortuous paths may be encountered along the member path.

According to some methods, the sleeve is deployed onto an elongate body of the medical device, after the body has been advanced through a lumen of the introducer shaft and to an implant site within a body of a patient, by pulling the introducer shaft proximally, out from the body of the patient, while holding the deployment tool in place, relative to the advanced body of the device.

  • Patent number: 9427257
    Abstract: A surgical access port for passage through body tissue to provide access to an underlying tissue site is provided. The access port has a working channel dimensioned for receiving a surgical instrument and a seal assembly for providing a substantial seal before, during and after insertion of a surgical instrument. The seal assembly includes an instrument seal and a zero seal. The instrument seal includes a proximal base that is interconnected to a distal instrument engaging portion by an elongate supporting portion. The engaging portion has a lateral dimension larger than the lateral dimension of the supporting portion forming a bulbous, mushroom-like head. The lateral dimension of the engaging portion decreases toward a distal opening of the instrument seal such that the distal end of the engaging portion is substantially perpendicular to the seal axis. The supporting portion closely conforms to an inserted instrument and serves to align the distal end of the seal.

  • Patent number: 9345855
    Abstract: A catheter grip and catheter assembly are provided. The catheter grip includes a body portion adapted to extend circumferentially around a catheter shaft of the catheter assembly to facilitate gripping of the catheter shaft by a user. The catheter grip also includes a head portion through which the catheter shaft can be fed and a biasing mechanism. The biasing mechanism biases the body portion and the head portion away from one another.

  • Patent number: 9233232
    Abstract: A liquid catheter, in particular a urinary catheter, includes a catheter shaft part (21) with a longitudinal liquid channel extending between a proximal and distal side thereof, and an anchoring body (22). The catheter body is intended to be received fully internally in a body cavity, such as in particular the urine bladder (50), and to drain the bladder from inside via the urethra (51). The catheter body has a length to span a distance between the bladder and a closure point (35) of the sphincter urethra. An operating member (24,25) is connected durably to the catheter body to enable a user to carry the catheter body transluminally out of the bladder past the closure point. An insertion device for the catheter includes an insertion sleeve which can be carried transluminally as far as the urine bladder and from which the catheter body can be carried into the bladder.

  • Patent number: 9211234
    Abstract: A configurable percutaneous endoscopic gastrostomy tube includes a shaft having a distal end and a proximal end. The shaft defines a lumen therethrough for passage of a feeding solution or medicine. An expandable retainer is located on the shaft, the retainer having a deployed position and an insertion position. The tube includes a releasable lock for maintaining the expandable retainer in its deployed position, the releasable lock located on the shaft proximal to the expandable retainer. A flexible sheath surrounds the expandable retainer, the sheath being generally loose around the retainer when the retainer is in an insertion position and the sheath being generally snug against an exterior surface of the retainer when the retainer is in a deployed position.

  • Patent number: 9056015
    Abstract: A spinal intervertebral support implant, for fusion or for dynamic stabilization purposes. A rod, preferably in the form of a screw, is inserted obliquely from the pedicle of an inferior vertebra into the body of a neighboring superior vertebra, through the disc space. The rod can be anchored into the body of the superior vertebra by means of a force fit or a screw thread. A pile of elements is disposed on the rod in the disc space like a pile of washers, so that the compression load between vertebrae is carried partly by these elements. These elements can be inserted through the bore through which the rod was inserted in a tightly folded configuration, and deployed into their washer-like form only when in position in the intervertebral space, such that there is no need for any additional incisions.

  • Patent number: 9039726
    Abstract: Braid-balls suitable for aneurysm occlusion and/or parent vessel occlusion/sacrifice (e.g., in treating neurovascular defects) are disclosed. Especially for aneurysm treatment, but also for either one of the aforementioned treatments, the form of the ball is very important. In particular, the density of the device is paramount in applications where braid itself is intended to moderate or stop blood flow—allowing thrombosis within a volume formed by the ball.

  • Patent number: 8840601
    Abstract: Disrupting tissue and devices and systems for disrupting tissue. The disclosure describes ways to deliver moieties to a target tissue, where the target tissue in general is not at the point of introduction, in such a way that minimal damage is produced in the tissue at the point of introduction. In some embodiments this is accomplished by jetting fluid at high velocity into the target tissue. The disclosure further describes novel agents deliverable in such systems for use in remodeling tissues. Some of these agents comprise a liquid while others do not. Additionally, although not specifically described in detail much of the disclosure may additionally be used in the delivery of therapeutic drugs.

  • Publication number: 20140276628
    Abstract: Catheter assemblies, kits and methods allowing for the drainage or administration of fluid or small particles are disclosed. A catheter assembly can include a shaft with a lumen, an expandable retention member, an elongate actuation member and a locking mechanism. The expandable retention member can be positioned at a shaft distal end portion and can include one or more filaments forming a plurality of drainage or administration interstices of variable or uniform size. The elongate actuation member can include an actuation member distal end, directly or indirectly engaged with the expandable retention member, and an actuation member proximal end. Movement of the actuation member proximal end relative to a proximal end of the shaft can cause the expandable retention member to change from a lower-profile configuration to a higher-profile configuration. A moved position of the elongate actuation member can be secured by rotating, sliding or otherwise manipulating the locking mechanism.
