Publication number: 20200391024Abstract: A handheld stimulator device is described that can deliver a stimulus to tissue of a user. For example, the stimulator device can include a stimulator probe including an electrode and a deformable element configured to assist with allowing stimulus delivery by the electrode. The handheld stimulator device can also include a stimulator body configured to releasably couple to the stimulator probe. The stimulator body can include a power source and at least one contact pin positioned along the stimulator body to, during coupling of the stimulator body to the stimulator probe, form an initial contact configuration with the deformable element in an original state and cause the deformable element to transition into a deformed state. The formation of the initial contact configuration and the deformable element in the deformed state can allow delivery of a stimulus by the stimulator probe.Type: ApplicationFiled: June 9, 2020Publication date: December 17, 2020Inventor: John L.

Patent number: 8029470Abstract: Systems and methods for penetrating a tissue membrane to gain access to a target site are disclosed. In some examples, systems and methods for accessing the left atrium from the right atrium of a patient's heart are carried out by puncturing the intra-atrial septal wall. One embodiment provides a system for transseptal cardiac access that includes a stabilizer sheath having a side port, a shaped guiding catheter configured to exit the side port and a tissue penetration member disposed within and extendable from the distal end of the guide catheter. The tissue penetration member may be configured to penetrate tissue upon rotation and may be coupled to a distal portion of a torqueable shaft. In some embodiments, the stabilizer sheath and shaped guiding catheter may be moved relative to the patient's body structure and relative to each other so that a desired approach angle may be obtained for the tissue penetration member with respect to the target tissue.Type: GrantFiled: September 30, 2004Date of Patent: October 4, 2011Assignee: Pacesetter, Inc.Inventors: James S.

Patent number: 7967790Abstract: A hemostasis valve is disclosed herein. The hemostasis valve may include an inner bushing, a rotation sleeve, an elastomeric sleeve, and a biasing element. The rotation sleeve may extend about the inner bushing and be rotationally displaceable relative to the inner bushing. The elastomeric sleeve may include a first end operably coupled to the inner bushing, a second end operably coupled to the rotation sleeve, and an iris valve portion. Rotation of the rotation sleeve relative to the inner bushing may cause the iris valve to transition from an open state to a closed state. The biasing element may act between the rotation sleeve and inner bushing to bias the iris valve towards at least one of a closed state or an open state.Type: GrantFiled: September 1, 2009Date of Patent: June 28, 2011Assignee: Pacesetter, Inc.Inventors: James S.

Patent number: 7890186Abstract: An anchoring device and a delivery method thereof can effectively provide a means for securing an implant to a wall of an internal organ within a patient in a variety of clinical applications. In one embodiment, an anchoring device used to retain a cardiac pressure measurement device is provided. The device is implanted in the body by deforming it to a small cross section profile, sliding it through a low profile delivery device and ejecting from the delivery device at a targeted site. The anchoring mechanism, when ejected from the delivery device, reverts back to pre-formed configuration and engages opposite sides of an organ wall, thereby anchoring the implant in the organ wall.Type: GrantFiled: December 5, 2006Date of Patent: February 15, 2011Assignee: Pacesetter, Inc.Inventors: John L. Wardle, Neal L. Eigler

Publication number: 20110022057Abstract: A transfer guidewire assembly configured to manipulate an implanted elongate body includes a flexible elongate portion, such as a guidewire, and coupler. The flexible elongate body has a proximal end and a distal end attached to the coupler. The coupler can include a catheter and/or a handle. The handle can include a screw. The coupler is configured to be removably attached to the end of an implanted elongate body, for example, by forming an interference fit with the outside diameter of the implanted body. A method for transferring an end of an implanted medical component from first site to a second site within a patient, such as a pacemaker, defibrillator, and/or sensor lead, etc., includes inserting a guidewire into the body at the first site and externalizing the guidewire at the second site. A proximal portion of the implanted component near the first site and is attached to the guidewire.Type: ApplicationFiled: July 23, 2010Publication date: January 27, 2011Applicant: PACESETTER, INC.Inventors: Neal L.

In some examples, systems and methods for accessing the left atrium from the right atrium of a patient's heart are carried out by puncturing the intra-atrial septal wall. One embodiment provides a system for transseptal cardiac access that includes a guiding catheter, an access catheter and a guidewire. The access catheter may include a tissue penetration member disposed within a housing wherein the tissue penetration member is substantially contained within the housing when in a retracted configuration. When the distal end of the access catheter is disposed adjacent the septal wall, the user can initiate an actuator switch, which may be in a proximal portion of the system, to cause the tissue penetration member to extend through the septal wall.Type: GrantFiled: July 12, 2004Date of Patent: March 16, 2010Assignee: Pacesetter, Inc.Inventors: James S.

Patent number: 7115052Abstract: Sport ball training devices and methods for releasably holding a tennis ball or other sport ball at an appropriate height for the practice of striking the ball, either directly or indirectly with a racket or the like. An embodiment may have a support device with a base and an adjustable vertical tubular assembly for the support of a transverse arm from which a ball sling is suspended. A retainer member of the ball sling circumferentially holds a sport ball. An embodiment of the retainer member may be made from an elastometric material that lightly squeezes the ball with sufficient force to restrain it, but releases easily when the ball is hit so that the trajectory of the ball is not affected by the presence of the retainer member nor is the racquet significantly affected by the presence of the ball sling generally.Type: GrantFiled: July 21, 2004Date of Patent: October 3, 2006Assignee: Pro Tennis Training, Inc.Inventors: John L.
