  • Patent number: 11259837
    Abstract: A device for dividing a fibrous structure comprising a catheter; an expandable member positioned near a distal end of the catheter and in fluid communication with a lumen of the catheter; and a cutting element situated on an outer surface of the expandable member. A method for dividing a fibrous structure comprising positioning, proximate the fibrous structure, an expandable member having a cutting element situated thereon; expanding the expandable member outwards to tension the fibrous structure across the cutting element; and activating the cutting element to weaken or cut the fibrous structure. A method for treating carpal tunnel syndrome comprising inserting a needle into the carpal tunnel; directing a guidewire to a position proximate the transverse carpal ligament; advancing, along the guidewire, a device having an expandable member and a cutting element; positioning the cutting element; tensioning the ligament across the cutting element; and weakening or cutting the ligament.

  • Publication number: 20220054115
    Abstract: Methods and systems for cell collection. Methods and systems include a collection mechanism being transformable between a collection state having an expanded diameter and a retrieval state where the diameter is less than that of the collection state and a conveyance mechanism having a distal end to which the collection mechanism is attached and designed to place the collection mechanism at a site of interest for cell collection. The Methods and systems also include an activation mechanism to transform the collection mechanism between the collection state and the retrieval state.

  • Publication number: 20210369337
    Abstract: A device for dividing a fibrous structure comprising an expandable member positioned near the distal end of a catheter and in fluid communication with the lumen of the catheter so that the expandable member can be biased between an inflated state and a deflated state to tension the fibrous structure, and electrosurgical elements situated on or proximate to an outer surface of the expandable member and configured to deliver electrical and thermal energy to the tensioned fibrous structure in a manner that results in division of the tensioned fibrous structure. A method for dividing a fibrous structure comprising positioning proximate the fibrous structure an expandable member having electrosurgical elements, expanding the expandable member outwards to tension the fibrous structure across the electrosurgical elements, and activating the electrosurgical elements to deliver energy to the tensioned fibrous structure to divide the tensioned fibrous structure.

  • Patent number: 10687883
    Abstract: Systems and methods for continuous infusion of a fluid, which may be heated, into a balloon catheter. A system for balloon inflation, the system comprising a catheter having an inflow lumen and an outflow lumen, a balloon positioned at a distal end of the catheter, the balloon being in fluid communication with the inflow and the outflow lumen, and an infusion device in fluid communication with the balloon through the inflow and outflow lumens, the infusion device configured for continuously circulating a fluid into and out of the balloon to maintain the balloon at a constant pressure and volume by matching a flow of the fluid into the balloon via the inflow lumen with a flow of the fluid out of the balloon via the outflow lumen in order to keep the balloon volume and pressure constant during an entire infusion.

  • Patent number: 10434296
    Abstract: Example embodiments are related to intraosseous infusion port (IOP) devices to provide access to bone marrow cavities. The IOP device according to example embodiments may comprise a proximal portion with a hollow chamber extending through the proximal portion, the hollow chamber having a proximal inlet for receiving an insertion device. The IOP device may also include an anchor portion positioned distally to the proximal portion, the anchor portion may be configured for anchoring the infusion port device in a bone, and an open-ended channel extending through the anchor portion, the channel being in fluid communication with the hollow chamber, such that, when the infusion port is implanted into a bone, the channel and the hollow chamber create a substantially straight pathway terminating at an opening at its distal end for insertion of the insertion device towards the bone marrow.
