  • Patent number: 11083874
    Abstract: A catheter has a double-action retention mechanism with (a) one retention mechanism having a reinforced retention body transformable into a deployed flower-like configuration when the catheter is inserted in the bodily cavity, and (b) a stabilizer securing the catheter to a patient's body to maintain a stable position. The retention mechanism for securing the catheter in the bodily cavity is configured with a thickened or reinforced wall portions of the retention body. The inner channel of the catheter body is wider than conventional catheters, thus attaining better drainage and better fluid flow. Due to the reinforced flower configuration, an inadvertent removal of the catheter with the flower configuration fully deployed will afflict no significant damage.

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.

  • Patent number: 9724125
    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: 9655506
    Abstract: Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally-invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly-expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be asymmetric around a stabilizer subsystem to maximize space for a tool and an endoscope to each be maneuvered independently to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.

  • Patent number: 9622828
    Abstract: An introducer and method provides a surgical tool with a pathway through tissue to a surgical site, wherein the surgical tool includes at least one surgical instrument. The introducer comprises a flexible sheath having a distal portion including a distal end and is arranged for receiving the surgical tool. A tissue separation tip at the distal portion of the sheath advances the sheath into the tissue towards the surgical site. The tissue separation tip is arranged to form a tissue gap and provide the at least one surgical instrument access to the tissue gap for performing a medical procedure consonant with the formation of the tissue gap or the performance of work at the surgical site.

  • Patent number: 9533128
    Abstract: Devices and methods for altering gaseous flow within a lung to improve the expiration cycle of an individual, particularly individuals having chronic obstructive pulmonary disease. The methods and devices create channels in lung tissue and maintain the patency of these surgically created channels in tissue. Maintaining the patency of the channels allows air to pass directly out of the lung tissue which facilitates the exchange of oxygen ultimately into the blood and/or decompresses hyper-inflated lungs.

  • Patent number: 9498596
    Abstract: A catheter with an improved retaining, activation and locking features is provided which is a safe device with reduced irritation and discomfort for a patient. The retaining mechanism positioned at the proximal end of the catheter assumes a “closed” position for introduction and removal of the catheter into and from the body cavity of a patient, and is transitioned into the “open” position when the catheter is positioned within the body cavity by mechanically manipulating the retaining mechanism through an activation mechanism having a piston member slideably displaceable within a cylinder housing member. A locking mechanism is included for maintaining the catheter in the “open” position.

  • Patent number: 9486607
    Abstract: A treatment device is provided including a catheter having a lumen that is opened to a distal end of the catheter; a wire passing through the lumen so that the wire is inserted into or retracted from the lumen; and a piece disposed at a distal end of the wire and having the maximum width when the piece is protruded from the distal end of the catheter is set larger than the diameter of the lumen, wherein the piece body is formed of a deformable material having a broad curved surface shape that distributes concentration of pressure acting on tissues, and when the wire is pulled in toward the catheter, the piece being extended in the axial direction by the lumen and reduced in its outer diameter so as to be pulled into the lumen.

  • Patent number: 9433756
    Abstract: An introducer assembly that may be employed to implant a medical device includes an introducer shaft, and an anchor sleeve and a deployment tool mounted on the shaft. 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: RE46306
    Abstract: A manually manipulatable tool for removing a fecal impaction, the tool is adapted for insertion into a patient's rectum to engage and penetrate the impaction. The tool is fitted with flexible, arcuately configured elements collapsible at least partially during insertion into the rectum and penetration of the fecal impaction, withdrawal of the tool deploying the elements to exert traction on the impaction thus facilitating withdrawal of at least portions of the impaction. A body member of the tool is preferably elongated and can optionally be provided with a longitudinally extending lumen for introduction of an enema solution concurrently with or independently of impaction removal.
