Various surgical introducer needle and anchor systems are provided. The systems can include an introducer needle and a tissue support implant or sling device. The implant device can include one or more anchoring devices. The introducer needle device can include a handle assembly and a needle assembly. The needle assembly can include a generally hollow needle, and a wire traversable therein. The wire can include a distal tip adapted to selectively retract or withdraw from the engaged anchoring device upon deployment of the anchor and/or implant.

Surgical needle device

In an electrode assembly for a catheter system, a plurality of struts extends from a proximal end to a distal end of the electrode assembly. Each strut has a longitudinally extending proximal leg, a longitudinally extending distal leg, and a center segment extending between and interconnecting the proximal leg and the distal leg. Each strut includes at least one electrode thereon, as well as one or more hinged aspects.

Electrode assembly for catheter system

Disclosed herein is an ablation catheter that includes an irrigation conduit, a force sensor, an electrode tip assembly, a seal, and a temperature sensor. The irrigation conduit defines an irrigation lumen configured to carry irrigation fluid to a distal end of the ablation catheter. The force sensors include a deformable body coupled to the irrigation conduit adjacent a distal end thereof. The electrode tip assembly is coupled to the deformable body and extends distally therefrom, and defines an interior cavity in fluid communication with the irrigation lumen and an exterior cavity in which a distal portion of the deformable body is received. The seal is disposed between the electrode tip assembly and the deformable body, and inhibits fluid flow between the interior cavity and the exterior cavity. The temperature sensor is coupled to the electrode tip assembly and extends from the electrode tip assembly through the irrigation lumen.

Aspects of the present disclosure are directed to intravascular electrophysiology catheters including a catheter handle with a steering-wire locking mechanism.

Steerable intravascular catheter with releasable locking mechanism

In an electrode assembly for a catheter system, a plurality of struts extends from a proximal end to a distal end of the electrode assembly. Each strut has a longitudinally extending proximal leg, a longitudinally extending distal leg, and a center segment extending between and interconnecting the proximal leg and the distal leg. A hinge interconnects the proximal leg and the center segment, and another hinge interconnects the distal leg and the center segment. The center segment of each of the struts has a corresponding electrode thereon. The electrode assembly is configurable between a collapsed configuration and an expanded configuration, with the electrodes being transversely spaced from the longitudinal axis of the electrode assembly a greater distance in the expanded configuration than in the collapsed configuration.

An introducer sheath () includes a body () extending between a leading end () and a trailing end () and including a plurality of rectangular segments () extending from the leading end to the trailing end. The segments are joined to one another along longitudinal edges to form a tubular structure with a lumen () therethrough, the segments being joined at vertices (). The body has a collapsed condition with a first cross-section and is configured to transition from the collapsed condition to an expanded condition with a second cross-section when an apparatus is passed through the lumen, the second cross-section having a maximum dimension larger than a maximum dimension of the first cross-section.

Various embodiments of a pelvic treatment system and method are provided. The present invention can include one or more drug eluting darts or barbs that are lodged into the wall and will elute the drug over a desired time period (weeks, months for example) to treat OAB, BPH, tissue weaknesses, or other disorders or diseases.

Drug releasing pelvic treatment system and method

The present disclosure is directed to electrode assemblies, and specifically to struts comprising electrode assemblies and electrodes contained on the struts. The electrode assembly struts are constructed to have a low profile and to have superior strength over the length of the strut such that an electrode assembly including the strut is highly resistant to radial compression. The electrodes included on the low profile, high strength strut also is designed to have a reduced profile such that electrode assemblies including the strut and electrode can easily be used with 6 French and smaller guide catheter assemblies.

High strength electrode assembly for catheter system including novel electrode

A system includes an introducer sheath having a sheath wall and a longitudinal axis, an electrode lead including a lead body and at least one electrode at a distal end of the lead body. The distal end of the lead body is received within the sheath. At least one anchor wire is within the sheath and has a proximal end attached to the distal end of the lead body. The a least one anchor wire moves through at least one opening in the sheath wall responsive to movement of the lead body relative to the introducer sheath.

Deployable electrode lead anchor

A stimulation therapy device provides an electrical stimulation therapy to branches of the tibial nerve of a patient. The device comprises a support member configured to be worn around the ankle or foot of the patient, first and second pairs of electrodes attached to the support member, and a stimulation circuit attached to the support member. The stimulation circuit is configured to deliver electrical stimulation pulses through the first and second pairs of electrodes.

Tibial nerve stimulation device

One embodiment of an electrode lead comprises a lead body, at least one electrode at a distal end of the lead body, an actuatable member and at least one anchor wire. The actuatable member is positioned within a lumen of the lead body. The at least one anchor wire has a proximal end that is attached to the actuatable member. Movement of the actuatable member relative to the lead body moves the at least one anchor wire through at least one opening in the lead body.
