  • Patent number: 10874551
    Abstract: A method and apparatus for performing a surgical procedure is provided. The surgical procedure may be a phacoemulsification procedure but other procedures may employ the techniques disclosed. The design includes sensing, within the surgical site, for a material change in fluid flow relative to a predetermined threshold. Upon sensing the fluid flow materially differs from the predetermined threshold, the design temporarily increases aspiration vacuum pressure to the surgical site above a predetermined upper threshold toward a maximum vacuum level. The design applies electrically generated disruptive energy, including but not limited to laser and/or relatively low power ultrasonic energy, to the surgical site from a first point in time measured from when aspiration vacuum pressure is above the predetermined upper threshold to a second point in time where pressure falls below a predetermined lower threshold.

  • Patent number: 10850032
    Abstract: An infusion apparatus for delivering medication includes a housing, a drive mechanism, a force sensor, and a transfer element. The drive mechanism comprises first and second conveying elements, the second conveying element for advancing a plug in a reservoir in the distal direction, the first conveying element with limited axial movement relative to the housing but rotatable to cause an ejecting or resetting movement of the second conveying element. The force sensor is arranged along a central axis between the housing and the proximal end of the drive mechanism. The transfer element is axially arranged between the force sensor and the first conveying element and the force sensor bears axial forces exerted by the ejection movement. The second conveying element moves the transfer element away from the first conveying element against the bias of a restoring force such that the force sensor bears axial forces exerted by the resetting movement.

  • Patent number: 10799648
    Abstract: A passive safety needle device is disclosed having a housing, a needle hub, a needle cannula, a retractable sheath, a spring to bias the retractable sheath in a distal direction to cover the distal end of the needle cannula, a radial protrusion to cause the spring to move from the proximal spring position to the distal spring position, and a catch to secure the distal end of the spring to the distal end of the housing. The spring may bias the retractable sheath in a distal direction to cover the distal end of the needle cannula. The radial protrusion causes the spring to move from a proximal spring position to the distal spring position towards the catch located at the distal end of the housing.

  • Patent number: 10709831
    Abstract: Method and apparatus for ultrafiltration of a patient being overhydrated due to congestive heart failure, comprising a cassette having four inlets/outlets. A patient tube is connected to a patient connector, intended to be connected to a patient line for access to a peritoneal cavity of the patient. The patient tube comprises a flow pump for addition and removal of a peritoneal fluid between the cassette and the peritoneal cavity. The fluid is introduced into an intermittent bag controlled by an intermittent valve and then returned the same way back to the peritoneal cavity. Glucose is metered into the fluid entering the peritoneal cavity by means of a glucose pump. Glucose is replenished continuously or intermittently for keeping a concentration of the osmotic agent substantially constant in the peritoneal cavity. After treatment, the peritoneal fluid is drained to a drain bag, wherein the drain tube comprises a drain valve and an albumin filter.

  • Patent number: 10668208
    Abstract: Restenosis or neointimal formation may occur following angioplasty or other trauma to an artery such as by-pass surgery. This presents a major clinical problem which narrows the artery. The invention provides a balloon catheter with a particular electrode configuration. Also provided is a method whereby vascular cells in the area of the artery subjected to the trauma are subjected to irreversible electroporation which is a non-thermal, non-pharmaceutical method of applying electrical pulses to the cells so that substantially all of the cells in the area are ablated while leaving the structure of the vessel in place and substantially unharmed due to the non-thermal nature of the procedure.

  • Patent number: 10561815
    Abstract: An anchoring system secures a catheter to the body of a patient and arrests axial movement of the catheter without impairing fluid flow through the catheter. The anchoring system can include an anchor pad 12 that adheres to the patient's skin and supports a retainer. The retainer can include interengaging structure that moves the retainer between an open and a closed position. When in the open position, the retainer can receive a portion of the catheter and be subsequently moved to the closed position. The interengaging structure can allow the retainer 20 to receive catheters of various sizes. The retainer can include one or more retention mechanisms to further inhibit axial movement of the catheter relative to the retainer when the catheter is secured therein. The anchoring system can include a mount that allows the retainer to rotate relative to the anchor pad.
