Abstract: An implant system and method of delivery includes a catheter system including a sling catheter having a plurality of distal openings and a delivery catheter, disposed within the sling catheter and having a distal port. Suture coupled anchors may be sequentially delivered by the delivery catheter to a cardiac treatment site by aligning the port of the delivery catheter with different openings of the sling catheter and pushing the anchor through the port and the sling catheter to embed the anchor into cardiac tissue such as tissue of a papillary muscle. Each anchor may have a linear configuration for translation within the delivery catheter and a biased configuration that inhibits its reentry into the sling catheter once deployed. Once all anchors are deployed, the suture may be tightened, the anchored portion of the sling catheter may be detached, and the catheter system withdrawn.

Abstract: An occlusive implant includes an expandable framework that is configured to shift between a collapsed configuration and an expanded configuration. An occlusive member is disposed along at least a portion of the expandable framework. At least part of the occlusive implant is configured to repel fibrinogen. In some cases, the occlusive implant may be configured for placement within a left atrial appendage (LAA) of a patient's heart.

Abstract: Aspects of positioning devices, methods, and systems are disclosed. An exemplary method comprises: moving a distal end of a tube into a body, the tube including a lumen and a shaft in the lumen, the shaft having a transducer; sending a first signal to the transducer; passing, with the transducer, in response to the first signal, a wave energy into the body; receiving, with the transducer, a reflected portion of the wave energy; generating, with the transducer, a second signal in response to the reflected portion of the wave energy; determining, with a processor, an indicia of the body in response to the second signal; and identifying, with the indicia, a targeted issue in the body; positioning the distal end of the tube at the targeted tissue in response to the indicia; and removing a portion of the targeted tissue with the distal end of the tube.

Abstract: Methods and systems for securing a medical implant at a valve. An illustrative method may include advancing a delivery system though a vasculature to a target location. At the target location, the delivery system may be proximally retracted to expose a medical implant carried within a lumen of the delivery system. The medical implant may be radially expanded from a collapsed delivery configuration an expanded deployed configuration. A fixation mechanism delivery system may be advanced through the vasculature to the target location. A first fixation mechanism configured to engage a native tissue and a portion of the medical implant may be deployed from the fixation mechanism delivery system. After deploying the fixation mechanism, the medical implant may be released from the delivery system.

Abstract: A guidewire system may include a guidewire having a relatively stiff proximal section and a relatively flexible distal section joined by a transition region, and a TAVI device slidably disposed on the guidewire. The guidewire may include an expandable element disposed about the transition region. The expandable element may be configured to expand from a collapsed configuration to an expanded configuration. The guidewire may include an expandable element disposed at the distal end. The distal section may be pre-configured to form more than one distal loop. A method of protecting an apex of a left ventricle during a TAVI procedure may include inserting a guidewire into the left ventricle, positioning a transition region adjacent the apex, expanding an expandable element such that the expandable element spans the apex, advancing a TAVI device distally over the guidewire to an aortic valve, and performing a TAVI procedure at the aortic valve.

Abstract: A radiopaque anchor and delivery device system may comprise a pigtail catheter and a radiopaque anchor. The pigtail catheter may be a dual lumen catheter configured to deploy the radiopaque anchor and delivery a radiopaque fluid or contrast agent. The implantable radiopaque anchor may be slidably disposed within and deployable from a lumen of the elongate shaft.

Abstract: A catheter is disclosed, which is capable of delivering embolization beads for treating uterine fibroids. The elongate catheter shaft includes a radially expandable portion at its distal end, which can expand radially locally when an embolization bead passes through it. In some cases, the catheter shaft includes a non-expandable portion, with an inner diameter comparable to the bead diameter, between the handle and the radially expandable portion. In some cases, the radially expandable portion is made from a tubular braid, stretched longitudinally over a mandrel, and encased in a lubricious soft polymer while still stretched. In other cases, the radially expandable portion is made from a slotted nitinol tube, encased in a lubricious soft polymer below the nitinol transition temperature. The polymer is thick enough to prevent the encased element from returning to its unstretched diameter or a larger size above the transition temperature.
