Medical devices having deformable structures providing medical lead fixation
First Claim

1. A method of fixing a proximal end of medical lead into a bore of a medical device, comprising:
- inserting the proximal end of the medical lead into the bore while a grip is coupled to the medical device; and
transferring force from the grip that is movable relative to the bore to a deformable structure constrained within the bore by the medical device to cause compression of the deformable structure so that the deformable structure engages the lead within the bore to fix the position of the lead as the deformable structure compresses.

Abstract
Medical devices include deformable structures that contact a lead upon being compressed. A grip that a clinician may grasp and manipulate is engaged with a nose structure of a header block of the medical device, and manipulation of the grip causes compression of the deformable structure to ultimately create fixation of the lead within the header block.

10. An medical device, comprising:
-
a header block having a bore with an engagement surface and a plurality of electrical connectors within the bore, the bore configured to receive a lead; a grip mechanically engaged with the engagement surface of the header block while the bore is lead-less; and a deformable structure that is constrained within the bore of the header block, the deformable structure providing a compression force in a radial direction of the bore when a force is applied from the grip to the deformable structure. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A medical system, comprising:
-
a medical device having a stimulation circuit and a header block, the header block having a bore with an engagement surface and a plurality of electrical connectors within the bore that are electrically coupled to the stimulation circuit; the medical device further comprising; a grip mechanically engaged with the engagement surface of the header block; and a deformable structure that is constrained within the bore of the header block, the deformable structure providing a compression force in a radial direction of the bore when a force is applied from the grip to the deformable structure; and a medical lead having a lead body surrounding electrical conductors, the lead body having a proximal region that is positioned within the bore of the header block after the grip has mechanically engaged the engagement surface of the header block, the proximal region having a plurality of contacts that engage corresponding electrical connectors in the bore and engage the conductors within the lead body, the deformable structure being compressed into contact with a portion of the proximal region of the medical lead to fix the medical lead within the bore. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
