A transseptal needle assembly comprised of a cannula, a handle assembly and a stylet is described. The cannula of the needle assembly is of a uniform body construction such that the cannula main portion and needle portion are fluidly connected in one-piece. The handle assembly comprises a handle housing, a handle sleeve and a handle slug. The handle slug provides ballast which improves tactile feel of the needle assembly. In addition, the stylet comprises a stylet housing having a hinged designed that allows for easier control of the stylet.

Transseptal needle assembly

In various examples, an apparatus includes a needle assembly including an outer cannula including a tubular sidewall disposed around a lumen. At least a portion of the sidewall includes an exterior including a polymeric material configured to inhibit skiving of an interior of a dilator with movement of the outer cannula within the dilator. An inner cannula is disposed within the lumen and is selectively slidable with respect to the outer cannula. A handle is disposed at a proximal portion of the needle assembly. The handle includes a first handle portion coupled to and movable with the outer cannula. A second handle portion is coupled to and movable with the inner cannula, wherein the first handle portion is selectively movable with respect to the second handle portion to extend a distal end of the inner cannula from within the lumen of the outer cannula.

Transseptal needle apparatus

In various examples, an apparatus includes a gripping member including a body and a gripping portion attached to the body. The body includes a passage configured to accept a needle cannula within the passage. The gripping portion includes an open configuration in which the needle cannula is movable within the passage and a closed configuration in which the gripping portion engages the needle cannula to inhibit movement of the needle cannula within the passage. A coupling member is rotatably attached to the gripping member. The coupling member is configured to selectively couple with a dilator. The coupling member includes a bore fluidly coupled with the passage, the bore being configured to accept the needle cannula within the bore.

A novel catheter is described. The catheter comprises a handle, an inner sheath providing an inner sheath lumen extending along a first length from a proximal inner sheath portion supported by the handle to a distal inner sheath portion connected to a cage gripper, and an outer sheath having a second length extending from a proximal outer sheath portion supported by the handle to a distal outer sheath portion connected to a cage housing. The inner sheath rotatably resides inside the outer sheath with the cage gripper rotatably housed inside cage housing. During a surgical procedure, a distal bridge portion of the inner sheath is connected to an opening in the lead sidewall with the lead received inside the cage housing. A gear knob is manipulated to cause the inner sheath to rotate with respect to the outer sheath so that the cage gripper is moved from an un-deployed position housed inside the cage gripper to a deployed position completely surrounding the lead connected to the distal bride. The catheter connected to the lead is moved into and to a desired location in a vasculature. Then, a screw driver is inserted through the housing and inner sheath lumens and into the lead and manipulated to screw the distal electrode into body tissue. Manipulating the gear knob causes the inner sheath to rotate the cage gripper from the deployed to the un-deployed position and then the catheter is separated from the lead and removed from the vasculature, leaving the lead behind.

Catheter for positioning a lead in the vasculature

An introducer assembly includes a sheath having a sheath proximal end and distal end, and a passage therethrough. The introducer assembly further includes a handle assembly that is mechanically and/or bonded coupled with a tubular sheath.
