A catheter adapted or high density mapping and/or ablation of tissue surface has a distal electrode array with offset spine loops, each spine loop having at least a pair of linear portions and a distal portion connecting the pair of linear portions, and one or more electrodes on each linear portion. The linear portions of the plurality of offset spine loops are arranged in-plane a single common plane, and the distal portions of the plurality of offset spine loops are arranged off-plane from the single common plane.

Catheter having closed loop array with in-plane linear electrode portion

A catheter comprising an elongated catheter body, and an electrode assembly distal of the catheter body, the assembly comprising a plurality of spines, wherein each spine has a distal end that is connected to the distal end of at least one other spine, wherein each spine has an electrode-carrying portion, the electrode-carrying portions of all spines of the assembly being in a single common plane, and wherein all spines of the assembly have a uniform exposed total length.

Catheter having closed electrode assembly with spines of uniform length

A mechanical thrombectomy device includes several clot arrestors mounted on a support wire. The clot arrestors have rings of expandable frame cells. The frame cell rings include an open frame cell ring, having a gap between adjacent frame cells in the ring, and a closed frame cell ring, having no gap between adjacent frame cells. The gap allows clots to enter the clot arrestor for retrieval from a target anatomy. Other embodiments are also described and claimed.

Thrombectomy device having open frame cell ring

A catheter comprising an elongated catheter body, an electrode array distal of the catheter body, the array having a mounting member and at least first and second spine supports. Each spine support includes a base having a planar configuration, and a plurality of spines extending from the base, wherein the first base extends in a first plane and the second base extends in a second plane different from the first plane in the mounting member.

Catheter with stacked spine electrode assembly

A mechanical thrombectomy device, and methods of manufacturing and using the mechanical thrombectomy device, are described. The mechanical thrombectomy device includes several clot arrestors independently mounted on a support wire. The clot arrestors have expandable frames that are eccentrically supported on the support wire. The independently and eccentrically mounted clot arrestors are arranged to allow a clot to pass into, and be captured by, one of the expandable frames. Furthermore, the independently and eccentrically mounted clot arrestors deform independently of one another such that retraction of the mechanical thrombectomy device through tortuous vasculature can stretch one clot arrestor without stretching another one of the clot arrestors to allow the clot to be retained by the unstretched clot arrestors. Other embodiments are also described and claimed.

Thrombectomy device and method

A spine that may be used in the electrode assembly of an electrophysiologic catheter having controlled flexibility. The spine may have a flexible core that extends through a length of the spine, a polymeric cover and a plurality of electrodes, each having at least one lead, distributed longitudinally along the spine. An amount of material forming the spine may be adjusted longitudinally along the spine to compensate for changes in flexibility to the spine caused by varying numbers of electrode leads present at different relative longitudinal positions along the spine.

Electrode assembly having spines with controlled flexibility

This disclosure is directed to a catheter having a basket-shaped electrode assembly with a high electrode density. The basket-shaped electrode assembly may have a plurality of spines, such as up to twelve, each with a plurality of electrodes, such as up to sixteen. The distal ends of the plurality of spines are joined at a distal hub, all of which are fashioned from a single piece of superelastic material.
