  • Publication number: 20200187975
    Abstract: Polypectomy devices and methods for making and using polypectomy devices are disclosed. An example polypectomy device may include an elongate sheath having a proximal end region and a distal end region. A shaft may be slidably disposed within the sheath. A handle may be coupled to the proximal end region of the sheath. The handle may be designed to axially shift the shaft relative to the sheath. A snare may be coupled to the shaft. The snare may include a first region, a traction region, and a distal tip region. The first region may have a non-circular cross-sectional shape. The traction region may include a plurality of traction members. At a position between two adjacent traction members the snare may have a reduced cross-sectional area relative to the first region. The distal tip region may have a circular cross-sectional shape.

  • Publication number: 20190358434
    Abstract: A guide extension catheter may include a proximal shaft and a tubular distal sheath including an exchange channel allowing for access (e.g. side access) into the lumen. Guide extension catheters may be used in conjunction with a guide catheter and a medical device having a distal region disposed within the guide catheter and a proximal region disposed outside of the guide catheter. A portion of the proximal region of the medical device can be passed through the exchange channel and into the lumen, and the guide extension catheter can be advanced into the guide catheter over the medical device without removing the medical device from the guide catheter. The exchange channel can extend in a straight line path along the sheath, or may extend in an indirect path along the sheath.

  • Publication number: 20190343528
    Abstract: Exemplary embodiments of the present disclosure relate to devices, systems, and methods for tissue resection in a body lumen of a patient, and may include an endoscope and a backstop delivery device extendable through the endoscope. The backstop delivery device may deliver a backstop to a location of selected tissue for resection. A backstop may include a covering being deployable in a patient. The covering may have one or more anchoring mechanisms disposed on an edge of the covering. A tissue resecting device may be extendable through the endoscope for resecting the selected tissue for resection. The covering may be deployable to an outer surface of the body lumen, such that the anchoring mechanism may secure the covering to the outer surface of the body lumen and the covering may expand to cover the selected tissue for resection.

  • Publication number: 20190275224
    Abstract: Devices and methods for assisting blood flow are provided. The device includes a housing with an inlet and an outlet, and a fluid barrier separating the housing into a first section containing the inlet and outlet, and a second section. The device also includes an impeller shaft coupled to an impeller and a first magnet in the first section of the housing, and a drive shaft coupled to a second magnet in the second section of the housing. The first and second magnets are arranged such that rotation of the drive shaft rotates the second magnet causing rotation of the first magnet, which drives the impeller.
